Product Configuration
SS304 material defrost heater for unit cooler is one of the indispensable key components in refrigeration equipment and air conditioning system. The unit cooler deforst heater main function is to prevent the evaporator surface from affecting the refrigeration efficiency due to frost formation in low temperature environment. This device is widely used in cold storage, refrigerated trucks, household air conditioning and industrial refrigeration equipment, etc., to ensure that the equipment can maintain efficient operation under various working conditions.
The core structure of the SUS304 material defrost heater is made of stainless steel tubes with spiral electrothermal wires embedded inside. Common materials include nickel-chromium alloy and iron-chromium alloy. These alloy wires are evenly distributed along the central axis of the tube to ensure that heat is evenly transferred to the tube wall. In order to improve the performance and service life of the heater, the void in the tube is usually filled with a specially modified magnesium oxide powder. This material not only has good insulation properties, can effectively prevent the occurrence of short circuit phenomenon, but also has excellent thermal conductivity, so that the heat generated by the electric heating wire is quickly transmitted to the tube wall.
The main function of the SUS304 material defrost heater for unit cooler is to heat the aluminum tube to the appropriate temperature through electrical energy, thereby melting the frost layer formed on the surface of the evaporator. When the refrigeration equipment is operated in a low temperature environment, the moisture in the air will condense on the surface of the evaporator and gradually form frost. If these frost layers are not removed in time, the heat transfer efficiency of the evaporator will be significantly reduced, and the refrigeration effect of the entire system will be affected. Therefore, the presence of SUS304 material defrost heaters is essential to maintain the normal operation of the equipment. In practical applications, defrosting heaters for unit cooler are usually used in conjunction with temperature control systems, which can effectively remove the frost layer without causing unnecessary thermal damage to the equipment by precisely controlling the heating time and temperature.
