Problems solved by technology

[0005] However, with the development of air conditioners, especially in ultra-low temperature refrigeration conditions, the outdoor unit of the air conditioner works at 60°C, and the main power module works at around 100°C. It cannot meet the heat dissipation requirements of the main power module, and the main power module is prone to thermal damage when it works for a long time under such working conditions
At the same time, the long-term operation of the main power module at high temperature will cause the efficiency of the main power module to drive the fan and compressor to decrease

Embodiment 1

[0027] Optionally, as in image 3 with Figure 4 As shown, the microchannel flat tube 21 is thermally connected to the base 1 through bolts or silicone grease through the outer surface of the outermost straight tube section 211 . The frequency converter transfers part of the heat to the base 1 of the radiator, and the heat on the surface of the micro-channel flat tube 21 is taken away by the refrigerant in the micro-channel flat tube 21, and flows into the header 3 with the flow of the refrigerant, and then flows out The radiator flows back into the pipeline of the outdoor unit of the air conditioning system, and this part of the heat is dissipated through the refrigeration circuit; the other part of the heat is transferred to the fins 22 through the microchannel flat tubes 21, and the natural convection between the fins 22 and the air will This part of heat is taken away, thus, the radiator completes a heat exchange process. Compared with traditional plate-fin radiators, es...

Embodiment 2

[0034] After a part of the heat of the frequency converter is transferred to the base 1, it needs to be transferred to the micro-channel flat tube 201 through the base 1, and the heat is taken away by natural convection between one side of the fin 202 in the micro-channel flat tube 201 and the air, Therefore, if Figure 5 with Image 6 As shown, in order to enable the heat on the base 1 to be quickly transferred to the fins 202, the flat microchannel tube 201 is connected to the base 1 through bolts or silicone grease through the plane formed by its side, so that The base 1 can transfer heat to the micro-channel flat tube 201 and the fins 202 at the same time, and then dissipate the heat generated by the frequency converter through the natural convection between the refrigerant in the micro-channel flat tube 201 and the fins 202 and the air, The heat dissipation speed is faster. Compared with the traditional plate-fin radiator, especially in high-temperature refrigeration and...

Abstract

The embodiment of the invention provides a cooler used for an air conditioner frequency converter and a variable frequency air conditioner, and relates to the technical field of heat exchange devices. The cooler and the variable frequency air conditioner are invented for solving the problem that an existing cooler is low in cooling efficiency. The cooler used for the air conditioner frequency converter is used for cooling the air conditioner frequency converter and comprises a base and a cooling part. The base is made from a heat conduction material. The cooling part and the base are connected in a heat transfer manner. The cooling part comprises a microchannel flat pipe. The microchannel flat pipe comprises at least two straight pipe sections parallel to one another, and elbow sections used for connecting the adjacent straight pipe sections. Fins are arranged between every two adjacent straight pipe sections. The two ends of the microchannel flat pipe are each connected with a collecting pipe. A microchannel inside the microchannel flat pipe communicates with the collecting pipes. The cooler used for air conditioner frequency converter and the variable frequency air conditioner are used for regulating the indoor temperature.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a radiator for an air conditioner inverter and an inverter air conditioner. Background technique [0002] With the improvement of people's living standards, air conditioners have become an important means for people to adjust indoor temperature, and the application of frequency conversion air conditioners is becoming more and more common. The speed of the compressor in the air conditioner keeps the compressor at the best speed state all the time, thus saving the energy consumption of the air conditioner. The frequency converter is usually installed in the outdoor unit of the frequency conversion air conditioner. Since the frequency converter is mainly composed of main power modules, a large amount of heat will be generated with the long-term use of these main power modules, which will cause the temperature of the main power modules to rise. If the heat Failure to...
