Description

Air conditioner outdoor unit and air conditioner

Technical Field

The present disclosure relates to the field of air conditioning technologies, and for example, to an outdoor unit of an air conditioner and an air conditioner.

Background

The frequency conversion power device is an important component in the frequency conversion air conditioner, and the higher the frequency of the compressor is, the more the heat productivity of the frequency conversion power device is. In addition, because the design of the frequency conversion power device is compact, the heat flow and the power density of the frequency conversion power device in the working process are continuously increased. Therefore, the cooling performance and reliability of the air conditioner under high-temperature working conditions are seriously affected by the heat dissipation problem of the variable-frequency power device.

For a multi-split air conditioner, a frequency conversion power device is mainly packaged by an Insulated Gate Bipolar Transistor (IGBT) array and a rectifier bridge chip, which is called a frequency conversion module for short. The frequency conversion module generally carries out heat dissipation and cooling in an air cooling aluminum fin mode. However, under the working condition of high ambient temperature, the temperature of the frequency conversion module is increased sharply because the high heat flux density and high power of the frequency conversion module cannot be effectively dissipated by using an aluminum fin radiator. In order to ensure the safety of the frequency conversion module and avoid the frequency conversion module from being burnt due to overheating, the frequency conversion module is generally prevented from being overhigh in temperature by adopting a compressor frequency reduction mode, but the refrigeration capacity of the air conditioner is greatly reduced in a high-temperature environment.

In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

the current radiator has insufficient heat dissipation capacity on the frequency conversion module under the high-temperature refrigeration working condition, so that the air conditioner greatly reduces the frequency, and the environment refrigeration effect in high-temperature days is poor.

Thus, the heat is transferred to the heat transfer working medium in the inflation channel 401 of the mounting edge part 402 by the base 30, the heat transfer working medium is heated and vaporized, the heat is rapidly transferred to the whole inflation plate fin 40, the inflation plate fin 40 is subjected to enhanced heat dissipation through air cooling, and the heat dissipation efficiency of the radiator is improved. Optionally, the inflation plate fin 40 further comprises an inflation portion 404, the inflation channel 401 being located at the inflation portion 404. Wherein the free portion 403, the inflation portion 404 and the mounting edge portion 402 are arranged in sequence, and neither the free portion 403 nor the mounting edge portion 402 is provided with an inflation channel 401. Optionally, the blowing plate fins 40 are provided with an injection port 405 for injecting a heat transfer medium. Optionally, the free portion 403 of the inflate plate fin 40 is provided with a pour port 405. The infusion port 405 communicates with the inflation channel 401. As shown in connection with fig. 2 to 5.

Optionally, the inflation channel 401 is inclined upwards at an angle a from the mounting edge portion 402 to the free portion 403, a > 5 °. Thus, the heat transfer medium is heated at the mounting edge portion 402, vaporized and turned into a gaseous heat transfer medium, which flows along the laterally inclined inflation channel 401 towards the free portion 403. Then, after the gaseous heat transfer working medium is condensed at the free portion 403 and changed into a liquid heat transfer working medium, the gaseous heat transfer working medium rapidly returns to the mounting edge portion 402 along the inflation channel 401 under the action of pressure difference and self gravity, so that a thermal circulation loop is realized.

Alternatively, as shown in connection with fig. 4 and 5, the blowing plate fin 40 includes a missing corner edge portion 406, wherein the missing corner edge portion 406 includes a mounting edge portion 402, and an extension portion extending along the mounting edge portion 402, the mounting edge portion 402 and the extension portion forming a missing corner 407.

For ease of distinction and understanding, the mounting edge portion of the blowing plate fin is defined as the "first mounting edge portion". The mounting edge portion of "the missing edge portion 406 includes the mounting edge portion" is defined herein as "the second mounting edge portion". The extension is located between the first mounting edge portion and the second mounting edge portion. Wherein the distance from the first mounting edge portion to the free portion 403 is greater than the distance from the second mounting edge portion to the free portion 403. Between the second mounting edge portion to the free portion 403 an inflation channel 401 is provided. The second mounting edge portion and the extension portion constitute a missing corner 407.

In practice, an inflation channel 401 is provided below the unfilled corner 407. And communicates with the inflation channel 401 between the second mounting edge portion and the free portion 403. Thus, in practical application, the heat transfer medium is heated and vaporized at the first mounting edge portion, and becomes a gaseous heat transfer medium, and the gaseous heat transfer medium flows along the transversely inclined inflation channel 401 towards the free portion 403 and the inflation channel 401 between the second mounting edge portion and the free portion 403. Gaseous heat transfer working medium is condensed at the free part 403 and/or the blowing part 404, and after the gaseous heat transfer working medium is changed into liquid heat transfer working medium, the gaseous heat transfer working medium rapidly flows back to the first installation edge part and the second installation edge part along the blowing channel 401 under the action of pressure difference and self gravity, so that a thermal circulation loop is realized. And the liquid heat transfer working medium reflowing to the second mounting edge part falls to the first mounting edge part under the action of gravity. Therefore, the liquid heat transfer working medium can rapidly flow back and exchange heat with the base 30 to dissipate heat and cool the frequency conversion module. Further, optionally, the base 30 is in thermally conductive connection with the first mounting edge portion and not in thermally conductive connection with the second mounting edge portion.

Optionally, two radiators are arranged laterally side by side at the back of the inverter module mounting part 201.

Through setting up two radiators, be favorable to further improvement to frequency conversion module's radiating efficiency. The temperature uniformity of the base 30 of the radiator is improved through the efficient phase change heat transfer of the base 30 of the radiator and the blowing plate fin group, so that the temperature uniformity and the heat dissipation efficiency of the whole radiator are improved.
