Jiangsu HELIKE Fluid Technology Co., Ltd. is a wholly-owned subsidiary of Dongxu Hydraulics. It is specialized in the research and development, design, production and sales of aluminum plate-fin heat exchangers.

1.Why Choose Air Cooler

● DX series products are designed in various types and specifications, which can meet the requirements of many different occasions. 

● The cooler should be equipped with various forms of bypass circuits to protect the cooler core from damage.

A. Pressure bypass loop

The pressure bypass circuit is divided into built-in or external pressure bypass circuit, and the opening pressure of the bypass valve is set to 5bar. When the pressure of the fluid entering the cooler is ≤5bar, the bypass valve is closed, and the fluid circulates back to the oil tank through the inner channel of the cooler. When the fluid pressure entering the cooler is ≥5bar, the bypass valve is opened. The fluid does not go through the inner channel of the cooler, but directly returns to the oil tank through the bypass circuit, which avoids or reduces the damage to the cooler caused by the back pressure caused by the impact pressure and excess flow.

B. Temperature control bypass loop

The operating temperature of the temperature control valve in the temperature control bypass circuit is 40°C, that is: 

- When the oil temperature is less than or equal to 40°C, the temperature control valve is opened, and the oil does not pass through the cooler. The bypass circuit returns directly to the oil tank, thus avoiding damage to the cooler and system components due to excessive back pressure generated under low temperature conditions. 

- When the oil temperature is higher than 40°C, the opening of the temperature control valve becomes smaller gradually. At this time, part of the fluid passes through the cooler, and part of the fluid returns directly to the oil tank. 

-When the oil temperature is higher than 60°C, the temperature control valve is completely closed, and all the fluid is cooled by the cooler. This bypass circuit is suitable for the system circuit with frequent low-temperature startups. In the lubrication system, due to the increase of oil viscosity at low temperature, a certain back pressure will be generated when passing through the cooler. This will increase the load of the system and cause certain damage to the cooler and system components, so it is recommended to use a temperature control bypass circuit for such a system. 

● DX series products are equipped with a temperature switch interface, which can also be used as an oil port, and the various types of oil inlet and outlet are convenient for installation and use. 

● For use in special environments, dust-proof nets or anti-stone nets can be installed to protect the cooler.
