The present embodiment provides an air conditioner that performs a cooling and heating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The cooling and heating cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant medium to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigerating effect by heat exchange with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor, an outdoor heat exchanger, and an outdoor fan, the indoor unit of the air conditioner includes a portion of an indoor heat exchanger and an indoor fan, and a throttling device (such as a capillary tube or an electronic expansion valve) may be provided in the indoor unit or the outdoor unit.

The refrigeration working principle of the air conditioner is as follows: the compressor works to enable the interior of the indoor heat exchanger (in the indoor unit, the evaporator at the moment) to be in an ultralow pressure state, liquid refrigerant in the indoor heat exchanger is rapidly evaporated to absorb heat, air blown out by the indoor fan is cooled by the coil pipe of the indoor heat exchanger to become cold air which is blown into a room, the evaporated and vaporized refrigerant is compressed by the compressor, is condensed into liquid in a high-pressure environment in the outdoor heat exchanger (in the outdoor unit, the condenser at the moment) to release heat, and the heat is dissipated into the atmosphere through the outdoor fan, so that the refrigeration effect is achieved by circulation.
The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor to become high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the indoor heat exchanger (the condenser at the moment), is condensed, liquefied and released heat to become liquid, and simultaneously heats indoor air, so that the aim of increasing the indoor temperature is fulfilled. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (an evaporator at the moment), is evaporated, gasified and absorbs heat to form gas, absorbs the heat of outdoor air (the outdoor air becomes cooler) to form gaseous refrigerant, and enters the compressor again to start the next cycle.
Referring to fig. 1 to 7, according to some embodiments of the present application, an outdoor unit of a top-discharge type air conditioner for connecting an indoor unit of an air conditioner includes: the air conditioner comprises a shell 1, a compressor (not shown), an outdoor heat exchanger 2, an outdoor fan 3, an electric control box 4 and a heat dissipation assembly 5.

In order to facilitate maintenance, disassembly and assembly of the heat dissipation assembly 5, the heat dissipation assembly 5 is detachably disposed on the front side of the circuit board 41.
Specifically, in the actual assembly process, the circuit board 41 is first installed in the electronic control box 4, and then the heat dissipation assembly is installed on the front side of the circuit board 41. Therefore, the heat sink 5 can absorb heat to the circuit board 41 and dissipate heat quickly, so that the heat sink 5 can dissipate heat and cool the circuit board 41.

Specifically, the case 401 is used for mounting the circuit board 41 and the heat dissipation assembly 5, and shields and protects the circuit board 41 and the heat dissipation assembly 5 through the case cover 402.
In another embodiment, the front surface of the circuit board 41 is formed with a mounting area (not labeled) in which the heat sink assembly 5 is disposed and thermally conductively coupled to the circuit board 41. Specifically, a separate mounting area is formed on the circuit board 41 for mounting the heat dissipating component 5, and no electronic components will be arranged in the mounting area.
In order to facilitate the assembly of the heat sink assembly 5 and the circuit board 41, the circuit board 41 is provided with a heat conducting base 42 in the mounting area, the heat conducting base 42 is provided with heat pipes 43, and the heat pipes 43 penetrate through the circuit board 41 and are distributed on the back surface of the circuit board 41; the heat dissipation assembly 5 is disposed on the heat conduction seat 42.
Since the heat dissipating component 5 is arranged at the mounting area of the circuit board 41, and the electronic components are arranged at the periphery of the mounting area. Heat generated from the electronic component is transferred to the heat dissipating member 5 through the circuit board 41, and thus, a reduction in heat dissipation efficiency of the electronic component away from the mounting area occurs.
By arranging the heat pipe 43 on the back of the circuit board 41, heat generated by electronic components in different areas on the circuit board 41 can be quickly absorbed by the heat pipe 43 at the back. The heat pipe 43 can rapidly transfer heat to the heat conducting base 42, and further transfer heat to the heat dissipation assembly 5 through the heat conducting base 42, so as to meet the requirement of uniform heat dissipation in different areas of the circuit board 41.
As for the heat conduction seat 42, it can be made of a material having good heat conduction performance, for example; aluminum or copper and other materials with excellent heat-conducting property. In addition, the heat conducting base 42 can be connected to the circuit board 41 by means of screw fixation or embedding, and the heat dissipating assembly 5 is fixed to the heat conducting base 42 by screws, and a first heat conducting gasket 43 is disposed between the heat conducting base 42 and the heat dissipating assembly to reduce an assembly gap therebetween, thereby improving heat transfer efficiency.
The heat pipes 43 are disposed on the back of the circuit board 41 in a winding manner to cover the circuit board 41 to the maximum extent. In order to increase the heat transfer area with the circuit board 41, the heat pipe 43 is adhered to the back surface of the circuit board 41 by a heat conductive adhesive.
In other embodiments, in order to improve the heat dissipation performance, the heat dissipation assembly 5 absorbs the heat released by the electronic control board 41 by using the cooling medium.
Specifically, the heat dissipation assembly 5 performs heat dissipation processing on the electronic control board 41 by using a refrigerant flowing in the refrigeration circuit. The heat released by the electric control board 41 is directly absorbed by the heat dissipation assembly 5, and the heat is quickly taken away by the circularly flowing refrigerant, so that the requirement of quick heat dissipation of the electric control board 41 is met.
In some embodiments of the present application, in order to enable the heat released by the electronic control board 41 to be directly and efficiently absorbed and carried away by the heat dissipation assembly 5, the heat dissipation assembly 5 includes: a heat-conducting plate 51 and a refrigerant heat-radiating member 52.
As for the heat conductive plate 51, it is used for conducting heat. For example: can be made of materials with good heat-conducting properties, such as; aluminum or copper and other materials with excellent heat-conducting property.
The refrigerant heat dissipating member 52 has a refrigerant flow passage formed therein for flowing a refrigerant; the refrigerant flowing into the refrigerating circuit in the refrigerant flow passage absorbs heat to take away heat.
The heat conductive plate 51 is sandwiched between the refrigerant heat-dissipating member 52 and the electric control plate 41, and the heat conductive plate 51 is thermally connected to the refrigerant heat-dissipating member 52 and the electric control plate 41, respectively. The heat generated by the operation of the electric control board 41 is directly absorbed by the heat conducting plate 51, and the heat is transferred to the refrigerant heat dissipating member 52 by utilizing the excellent heat conducting performance of the heat conducting plate 51. Because flowing refrigerants pass through the refrigerant heat radiating part 52, the flowing refrigerants absorb heat conducted by the heat conducting plate 51, and further the refrigerants directly absorb heat of the electric control plate 41, so that the purpose of quickly radiating heat is achieved.
In other embodiments of the present application, the coolant heat dissipation part 52 includes: a heat conduction block 521 and a refrigerant pipe 522.
Similarly, the heat-conducting block 521 may be made of a material having excellent heat-conducting property, such as aluminum or copper, and is used for conducting heat. The refrigerant pipe 522 is used to transmit the refrigerant. The refrigerant pipe 522 is provided on the heat-conducting block 521, and the heat-conducting block 521 is provided on the heat-conducting plate 51.
The heat conducting plate 51 absorbs heat generated by the electric control plate 41 and transfers the heat to the refrigerant pipe 522, and the refrigerant flowing in the refrigerant pipe 522 absorbs heat and rapidly takes away the heat.
In order to increase the heat conduction area, the refrigerant pipe 522 may be sandwiched between the heat conduction block 521 and the heat conduction plate 51, on one hand, one side of the refrigerant pipe 522 directly contacts with the heat conduction plate 51 to absorb heat, and on the other hand, the heat conduction block 521 absorbs heat conducted by the heat conduction plate 51 and is absorbed by the other side of the refrigerant pipe 522 in a heat conduction manner, thereby improving the heat conduction efficiency.
In addition, in order to increase the heat conduction area of the refrigerant pipe 522, the refrigerant pipe 522 may be wrapped by the heat conduction block 521, that is, a groove is formed in the heat conduction block 521, and the refrigerant pipe 522 passes through the groove, so that the pipe wall circumference of the refrigerant pipe 522 is uniformly contacted with the heat conduction block 521 well, and thus, the heat conduction area of the refrigerant pipe 522 can be effectively increased, and the heat dissipation efficiency is improved.
In some embodiments of the present disclosure, for the manner of flowing the refrigerant into the refrigerant pipe 522, the refrigerant pipe 522 may be connected in series in the refrigeration circuit of the air conditioner. Thus, after the compressor is started, a refrigerant flows through the refrigerant pipe 522, and the heat dissipation performance is improved to the maximum extent.

During heating operation, the exhaust gas of the compressor enters the indoor heat exchanger through the four-way valve, the heat is condensed and released in the indoor heat exchanger to generate a heating effect, the heat is released to the indoor environment in the refrigerant condensation process, the temperature of the condensed liquid refrigerant is higher than the temperature of the indoor environment, the indoor temperature of the common heating operation is higher than the outdoor temperature, and the temperature of the refrigerant is also far higher than the temperature of the outdoor environment; at this time, the indoor expansion valve is fully opened, and no throttling is performed, so that the refrigerant returns to the outdoor side through the indoor expansion valve and enters the heat dissipation assembly 5, the temperature of the refrigerant is still higher than the ambient temperature, and condensation cannot be generated. Then the refrigerant enters an outdoor expansion valve for throttling, enters an outdoor heat exchanger for evaporation after being throttled, and then returns to the compressor to complete the heating cycle.
By adopting the control mode, under the condition of meeting the heat dissipation requirement of the electric control board 41, condensation caused by too low temperature of the heat dissipation assembly 5 can be avoided, and then the short circuit of the electric control board 41 caused by condensation can be avoided, so that the use reliability is improved.
