Cooling method for solar inverters

Leave a comment ,

Air cooling: Air cooling is a common cooling method. The air-cooled heat exchanger we produce has good heat dissipation effect and can adapt to inverters of different powers. We can design the number, position, and speed of fans for you based on the heating situation of the inverter, in order to achieve efficient heat dissipation.

Liquid cooling: For high-power solar inverters, liquid cooling is more suitable. Liquid cooling systems typically consist of cooling pipes, coolant pumps, radiators, and other components. The coolant circulates in the cooling pipes inside the inverter, absorbing heat and dissipating it to the outside through the radiator. Our liquid cooled heat exchanger has the advantages of high heat dissipation efficiency, precise temperature control, and low noise.

The importance of cooling for solar inverters

Leave a comment

Solar inverters generate heat during operation due to energy losses in their internal power devices during the conversion of electrical energy, which are released in the form of thermal energy. If this heat is not dissipated in a timely manner, the temperature of the inverter will continue to rise.

Excessive temperature can have a negative impact on the performance and lifespan of inverters. On the one hand, an increase in temperature can lead to a decrease in the performance of power devices, a decrease in conversion efficiency, and thus affect the overall power generation efficiency of the solar power generation system. On the other hand, long-term high-temperature operation will accelerate the aging of components, increase the probability of faults, and shorten the service life of inverters.

How does the heat exchanger function in the mushroom cultivation workshop

Leave a comment ,

Mushroom cultivation and ventilationHeat exchangers have various important uses in the edible mushroom cultivation industry. Heat exchangers can be used to optimize the ventilation system of mushroom cultivation workshops, accurately control the temperature and humidity of the air entering the workshop, provide a stable and suitable environment for the growth of edible mushrooms, and improve the yield and quality of edible mushrooms.

1. Control the cultivation temperature: The temperature of the cultivation environment can be precisely adjusted through a heat exchanger, providing stable and suitable temperature conditions for the growth of mycelium, promoting rapid and robust growth of mycelium, and shortening the cultivation period.

2. Adjust air humidity: Edible fungi require suitable air humidity for growth, generally around 85% -95%. Heat exchangers can be used in conjunction with air handling systems to regulate the humidity of the air by heating or cooling it. When the humidity is low, heat the air to contain more water vapor, and then increase the air humidity by spraying water or other methods; When the humidity is high, cooling the air can condense water vapor, reduce air humidity, and create a suitable humidity environment for the growth of edible fungi.

3. Optimize the ventilation system: Good ventilation is required during the cultivation process to provide sufficient oxygen and exhaust gases such as carbon dioxide. The heat exchanger can preheat or pre cool the fresh air entering the cultivation chamber, avoiding temperature fluctuations and affecting the growth of edible fungi. At the same time, it can also recover heat from the discharged exhaust gas, saving energy.

4. Fermentation process control: In the liquid fermentation culture of edible mushrooms, heat exchangers are used to control the temperature inside the fermentation tank. During the fermentation process, microbial metabolism generates heat. If not removed in a timely manner, it can lead to excessive temperature and affect the fermentation effect. The heat exchanger removes excess heat by circulating cooling water or other cooling media, maintains the fermentation temperature within an appropriate range, and ensures the stability of the fermentation process and the quality of the products.

How to ventilate the storage of agricultural products

Leave a comment ,

Cold storage ventilation: In cold storage, heat exchangers can be used for ventilation systems. Through heat exchange, fresh air is introduced while preventing external hot air from entering the cold storage and causing temperature fluctuations. This maintains a low temperature environment in the cold storage, reduces the operating time and energy consumption of refrigeration equipment, ensures the storage quality of agricultural products, and extends the storage period.
Granary ventilation: For granaries storing grain, the heat exchanger can adjust the temperature and humidity of the air during the ventilation process to prevent the grain from becoming moldy and deteriorated due to moisture and heat, keep the grain dry and low temperature, and ensure the safe storage of grain.

How to use heat exchangers in the livestock and poultry breeding industry

Leave a comment ,

Improving air quality: Livestock farms produce large amounts of harmful gases such as ammonia and hydrogen sulfide, as well as water vapor. Heat exchangers can transfer the heat from the polluted air discharged to the fresh air entering during the ventilation process, while achieving preheating and purification of the air, reducing the indoor temperature drop caused by ventilation, providing warm and fresh air for livestock and poultry, improving the breeding environment, and reducing the incidence of livestock and poultry diseases.
Reduce stress reactions: Due to the sensitivity of livestock and poultry to changes in environmental temperature, heat exchangers can gradually bring the temperature of the introduced fresh air closer to the indoor temperature, avoiding stress reactions caused by sudden temperature changes in livestock and poultry, which is beneficial for their growth, development, and production performance.

What is the role of heat exchangers in greenhouse cultivation

Leave a comment ,

1. Temperature regulation: In winter, the heat exchanger can recover the heat from the humid and hot air discharged from the greenhouse, preheat the cold air entering the greenhouse, reduce heating energy consumption, maintain stable indoor temperature, and promote crop growth. In summer, it can utilize cool nighttime air or low-temperature resources such as groundwater to cool the air entering the greenhouse through a heat exchanger, reducing indoor temperature and avoiding high temperature hazards to crops.
2. Humidity control: In some greenhouses with high humidity, heat exchange can be carried out through heat exchangers to remove moisture from the air during the cooling process, achieving the purpose of dehumidification, creating a suitable humidity environment for crops, and reducing the occurrence of pests and diseases.

The role of heat exchangers in agricultural ventilation

Leave a comment ,

Energy conservation and consumption reduction: In agricultural facilities such as greenhouses and breeding farms, heat exchangers can utilize the energy of exhaust air to pretreat fresh air. For example, in winter, transferring the heat from the exhaust to the incoming cold air can increase the temperature of the fresh air and reduce heating energy consumption; In summer, the cooling capacity of exhaust can be used to cool the fresh air and reduce the cooling load of air conditioning.
Improving the environment: By using heat exchangers for heat exchange, the temperature of the air entering agricultural facilities can be brought closer to the indoor ambient temperature, reducing temperature fluctuations caused by ventilation and providing a more stable and suitable environment for crop growth or animal husbandry. At the same time, some heat exchangers can achieve complete isolation between fresh air and exhaust air, avoid cross contamination, and ensure the cleanliness of fresh air, which is particularly important for agricultural production with high environmental requirements such as aseptic cultivation and SPF level animal breeding.

Plate heat exchanger: Its advantages are compact structure, high heat transfer efficiency, small footprint, and easy disassembly, cleaning, and maintenance. A ventilation system suitable for various agricultural facilities such as greenhouses and breeding farms, which can achieve efficient sensible heat exchange.
Heat pipe heat exchanger: With the heat pipe as the core heat exchange element, it utilizes the phase change heat transfer of the working fluid inside the pipe to achieve heat transfer. Heat pipe heat exchangers have the advantages of high heat transfer efficiency, good isothermal properties, and the ability to achieve long-distance heat transfer. In the agricultural field, especially in places with strict requirements for environmental temperature and humidity control, such as animal rooms and laboratories, heat pipe heat exchangers can effectively recover waste heat while avoiding cross contamination and adapting to a wide temperature range environment.
Shell and tube heat exchanger: composed of shell, tube bundle, tube plate and other components, the fluid flows in the tube and shell sides for heat exchange. The shell and tube heat exchanger has a sturdy structure and can withstand high pressure and temperature, making it suitable for large-scale agricultural facilities that require high stability and reliability of ventilation systems, such as large greenhouse clusters or large-scale breeding farms. By installing fins on the tube, its heat transfer efficiency can be further improved and its applicability in agricultural ventilation can be enhanced.

What is air to air heat recovery unit?

Leave a comment ,

An air-to-air heat recovery unit is a device that transfers heat (and sometimes moisture) between two separate air streams—typically incoming fresh air and outgoing exhaust air—without mixing them. It improves energy efficiency by recovering heat from the exhaust air to precondition the incoming air, reducing the energy needed for heating or cooling in HVAC systems or industrial processes.

Key Features:

  • Operation: Uses a heat exchanger (e.g., counterflow, cross-flow, or rotary) to transfer heat. In counterflow units, air streams flow in opposite directions for maximum efficiency (70-90%).
  • Types:
    • Plate Heat Exchangers: Fixed plates separate air streams, transferring sensible heat (temperature only).
    • Rotary Heat Exchangers: Rotating wheels transfer both sensible and latent heat (moisture).
    • Heat Pipes: Use phase-change technology for efficient heat transfer.
  • Applications: Ventilation systems in buildings, industrial processes, data centers, and energy recovery systems.
  • Benefits: Lowers energy costs, reduces carbon footprint, and maintains indoor air quality by preventing cross-contamination.
  • Example: In winter, a unit might transfer heat from warm exhaust air (e.g., 20°C) to cold incoming air (e.g., 0°C), raising the fresh air temperature to reduce heating demands.
