Radiator and air condensing units

Technical Field

The present application relates to the field of air conditioners, and for example, to a heat sink and an outdoor unit of an air conditioner.

Background

The inverter air conditioner has become the mainstream of the air conditioner industry, but with the continuous appearance of high-temperature weather in recent years, the high temperature of 42 ℃ or even close to 50 ℃ in summer attacks all places in the world. The air conditioner does not refrigerate, and the refrigerating capacity is reduced to become a new complaining point of users. In order to solve the user pain and meet the direction of people to good life, the high-temperature refrigeration non-attenuation air conditioner becomes a new research and development direction of air conditioning enterprises.

The frequency conversion chip is an important component in the frequency conversion air conditioner and determines the running frequency of the compressor. The higher the compressor frequency is, the stronger the refrigerating capacity in summer is, and the heating of the frequency conversion chip is increased rapidly at the moment. The frequency conversion chip mainly comprises: the inverter Module is a frequency conversion Module, which is formed by packaging and integrating an Intelligent Power Module (IPM for short), an Insulated Gate Bipolar Transistor (IGBT for short), a diode and a rectifier bridge. Since the frequency conversion module is the main heat source, the frequency conversion module may also be referred to as a heat source module. With the improvement of semiconductor technology, the chip design is more compact, the heat flux density of the chip is continuously increased, and the volume of the chip tends to be miniaturized. Therefore, the problems of high temperature, large heat flux density, high power heating and heat dissipation of the frequency conversion chip seriously restrict the working safety and high-temperature refrigerating capacity of the air conditioner. The high-temperature refrigeration of the air conditioner can be realized without attenuation only by solving the problem of high-temperature heat dissipation of the frequency conversion chip, which is very important in the field of air conditioners.

At present, in consideration of cost performance, an aluminum extruded section radiator is generally adopted for heat dissipation of a heat source module of an air conditioner outdoor unit, forced convection heat dissipation is realized by matching with a fan of the air conditioner outdoor unit, and heat dissipation optimization is performed by changing the area and the shape of fins of the aluminum extruded section radiator. However, due to the problems of small size and large heating power of the frequency conversion chip, the heat flux density generated by the frequency conversion chip is very high, and the conventional aluminum extruded section radiator cannot effectively solve the heat dissipation problem caused by the large heat flux density, so that the temperature of the frequency conversion module is rapidly increased at high ambient temperature, and the frequency reduction operation has to be carried out to ensure the operation safety of the air conditioner, thereby causing the phenomena of great reduction of the refrigeration capacity of the air conditioner and no refrigeration.

Part of the air conditioners adopt the compressor refrigerant pipeline to cool the frequency conversion chip, so that the cooling performance of the frequency conversion chip is ensured, but a part of the loss of the refrigeration energy of the compressor refrigeration system is also brought, and the overall refrigeration capacity is reduced although the working temperature safety of the chip is ensured. Moreover, the risk of the frequency conversion chip being burnt out by condensation and the leakage of the refrigerant exist, and the air conditioner can not work completely easily.
