Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant 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 liquid-phase refrigerant in a high-temperature and high-pressure state 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 cooling effect by heat-exchanging 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 and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator.

In order to achieve a better heat dissipation effect, the remaining structure after the heat dissipation assembly 30 is connected with the electronic control box 20 can be completely placed in the recessed portion 12 of the volute casing 10, so that the flowing air flow in the recessed portion 12 can take away the heat transferred from the electronic components in the electronic control box 20 to the heat dissipation assembly 30, and the purpose of dissipating the heat of the electronic components in the electronic control box 20 can be achieved.

Therefore, according to the utility model discloses an air conditioner 100, the produced heat of the inside electronic components of its automatically controlled box 20 passes through radiator unit 30 and transmits the depressed part 12 of spiral case 10, and the heat is again along with the outside transmission of the interior air current of depressed part 12 to reach the radiating purpose to the inside electronic components of automatically controlled box 20.

In the embodiment of the present invention, as shown in fig. 1, the electronic control box 20 includes: a case 21, a circuit board 22, and a support plate 23. The box body 21 is connected with the scroll casing 10 through a connecting piece 40, the box body 21 has a hollow portion 211, and the hollow portion 211 is communicated with the recessed portion 12.

In detail, as shown in fig. 1, in order to protect the circuit board 22, the circuit board 22 and the supporting plate 23 may be connected by screws, and then the supporting plate 23 is fixed to the bottom of the box body 21 by screws, at this time, the supporting seat 231 on the supporting plate 23 may pass through the hollow portion 211 on the box body 21 and protrude out of the outer surface of the box body 21. In addition, a through hole is formed in the connecting member 40 at a position corresponding to the hollow portion 211, and the size of the through hole is equal to that of the hollow portion 211, so that the heat dissipation assembly 30 can pass through the connecting member 40 to reach the recessed portion of the scroll casing 10.

The supporting seat 231 is a recess recessed toward one side of the circuit board 22, so that the heat dissipation assembly 30 can be placed on the supporting seat 231, and a portion of the heat dissipation assembly 30 is located on the supporting seat 231, and another portion is located in the outer space of the supporting seat 231. Wherein, the heat dissipation assembly 30 can be in clearance fit or over fit with the supporting seat 231, so that the supporting seat 231 can limit the heat dissipation assembly 30 to a certain extent. In addition, since the hollow portion 211 is located in the recessed portion 12, and the hollow portion 211 and the recessed portion 12 are communicated with each other, the free end of the heat dissipation assembly 30 is located in the recessed portion 12, and the flowing air flow of the recessed portion 12 can wrap the heat dissipation assembly 30, so that the heat in the heat dissipation assembly 30 is transferred to the flowing air flow.

As shown in fig. 1, the heat dissipation assembly 30 includes: a heat conductive plate 31 and heat radiating fins 32. The heat conducting plate 31 is connected to the support base 231, the heat radiating fins 32 are connected to the heat conducting plate 31, and the heat radiating fins 32 are inserted into the recess 12.

Specifically, as shown in fig. 1, the projection 311 is in contact with the power module 221 of the circuit board 22. Because the electronic components on the front surface of the circuit board 22 are arranged more, and there is not enough space to provide a heat sink structure, the power module 221 with large heat generation amount can be designed on the back surface of the circuit board 22, and the heat dissipation of the circuit board 22 is performed to the maximum extent by dissipating the heat of the power module 221 with the largest heat generation amount. In addition, since the surface area of the side of the power module 221 opposite to the supporting plate 23 is small, a protrusion 311 may be disposed on the heat conducting plate 31, and the surface area of the protrusion 311 contacting the power module 221 is equal. Therefore, the circuit board 22 can achieve the purpose of rapid heat dissipation in a limited space, and the manufacturing cost of the heat conducting plate 31 can be reduced, thereby reducing the production cost.

In the embodiment of the present invention, as shown in fig. 1, the heat conducting plate 31 is adhered to the supporting plate 23 or the heat conducting plate 31 is connected to the supporting plate 23 by screws. It can be understood that, since the heat dissipating fins 32 are located in the recessed portion 12 of the scroll casing 10, the recessed portion 12 has a flowing air flow, and when the flow rate of the air flow is high, the flowing air flow exerts a force on the heat dissipating fins 32, and the heat dissipating fins 32 exert a force on the heat conducting plate 31.

In addition, the plurality of reinforcing ribs 2313 are arranged on the supporting plate 23 to increase the structural strength of the supporting plate 23, and the plurality of reinforcing ribs 2313 arranged on the supporting plate 23 can stabilize the connection between the box body 21 and the connecting piece 40 to a certain extent because the supporting plate 23 is connected with the bottom of the box body 21 and the box body 21 is connected with the connecting piece 40.

In some optional embodiments of the present invention, the supporting plate 23 may be provided as a metal member. The metal member has good thermal conductivity and hardness, so that heat of the circuit board 22 can be transferred through the support plate 23 on one hand, and the support plate 23 can stably support the circuit board 22 on the other hand. For example, the metal piece may be made of iron, aluminum, or steel, etc.

Furthermore, the connecting member 40 is a sheet metal member. Since the sheet metal part has the characteristics of light weight, high strength, low cost and the like, the connecting member 40 is provided as the sheet metal part, so that the overall weight of the air conditioner 100 can be reduced while the box body 21 and the scroll case 10 can be stably connected.
