[0038] like Figure 1-Figure 5 As shown, the utility model provides a heat dissipation box 10, which includes a box body 100, a heat exchange part 200 and a flow equalizing part 300. The top of the box body 100 has a medium inlet 101, the bottom of the box body 100 has a medium outlet 102, and the box body 100 has a first side wall 103, and the first side wall 103 is used to connect with the electric control box. The heat exchange part 200 is arranged in the box body 100, and the heat exchange part 200 includes a plurality of heat exchange fins 201 arranged at intervals and connected to the first side wall 103. The flow equalizing part 300 is arranged between the heat exchange part 200 and the medium inlet 101, and the flow equalizing part 300 is used to evenly distribute the cooling medium entering from the medium inlet 101 to the plurality of heat exchange fins 201.

[0039] It should be noted that the first side wall 103 and the heat exchanger 201 of the box body 100 are both made of metal materials, so that the first side wall 103 and the heat exchanger 201 have good thermal conductivity. The first side wall 103 is generally directly connected to the outer shell 20 of the electric control box, so that the first side wall 103 can better dissipate heat from the electric control box.

[0040] The plurality of heat exchange fins 201 are generally arranged at intervals along the length direction of the box body 100 , that is, the plurality of heat exchange fins 201 are arranged at intervals along the length direction of the first side wall 103 , so that each position of the first side wall 103 can exchange heat through the heat exchange fins 201 .

[0041] The medium inlet 101 is generally connected to a cooling medium supply device, and the medium outlet 102 is generally connected to a cooling medium recovery device. After the cooling medium enters the box body 100 through the medium inlet 101, the flow equalizer 300 equalizes the flow so that the cooling medium can be evenly distributed on the heat exchange plate 201, taking away the flow on the heat exchange plate 201, and finally flowing out through the medium outlet 102.

[0042] It can be understood that the cooling medium flows in through the medium inlet 101 and is evenly distributed to the multiple heat exchange fins 201 through the flow equalizer 300. According to the principle of heat transfer, the heat is transferred from the high heat area to the low heat area. The first side wall 103 is used to take away the heat of the electric control box. The heat is transferred to the heat exchange fins 201 through the first side wall 103. The heat on the heat exchange fins 201 is taken away by the cooling medium. Through liquid cooling heat exchange, the heat dissipation box 10 can dissipate heat from the electric control box, thereby improving the heat dissipation efficiency of the electric control box.

[0043] In some embodiments, the box body 100 is generally made of metal material as a whole, and the box body 100 is in the shape of a rectangular parallelepiped, and the first side wall 103 is a side of the rectangular parallelepiped box body 100 along the length direction.

[0044] In some embodiments, the plurality of heat exchange fins 201 are arranged at equal intervals along the length direction of the first side wall 103 .

[0045] In some embodiments, along the height direction of the box body 100 , the heat exchange portion 200 and the flow equalizing portion 300 have a certain distance.

[0046] In some embodiments of the present invention, the flow balancing portion 300 includes a sponge layer 302 , and the orthographic projection of the sponge layer 302 on the bottom of the box body 100 completely covers the orthographic projection of the heat exchange portion 200 on the bottom of the box body 100 .

[0047] It should be noted that the sponge layer 302 is made of sponge.

[0048] It is understandable that after the cooling medium enters the box body 100, it first soaks the entire sponge layer 302, and then the saturated sponge layer 302 penetrates and drips onto each heat exchange fin 201 of the heat exchange part 200. Since the sponge layer 302 completely covers the heat exchange part 200, the sponge layer 302 can ensure that the heat exchange fins 201 at each location of the heat exchange part 200 can receive the cooling medium leaked from the sponge layer 302, thereby achieving uniform heat exchange of the heat exchange part 200, and further ensuring that the first side wall 103 can continuously dissipate heat from the electric control box. At the same time, due to the characteristics of the sponge layer 302, it can filter out most of the impurities in the cooling medium to prevent the impurities from clogging adjacent heat exchange fins 201.

[0049] In some embodiments of the present invention, the flow equalizing portion 300 also includes a filter mesh layer 301, which is arranged on the side of the sponge layer 302 close to the medium inlet 101, and the orthographic projection of the filter mesh layer 301 on the bottom of the box body 100 completely covers the orthographic projection of the sponge layer 302.

[0050] It can be understood that the filter layer 301 is arranged on the side of the sponge layer 302 close to the medium inlet 101. Before the cooling medium reaches the sponge layer 302, the filter layer 301 performs a coarse filtration on the cooling medium, thereby preventing larger impurities from clogging the sponge layer 302 and affecting the heat dissipation effect.

[0051] In some embodiments, the flow equalizing unit 300 includes a flow dividing plate, and the flow dividing plate includes a plurality of flow dividing holes, and each flow dividing hole is arranged in alignment with a heat exchange plate 201 .

[0052] In some embodiments of the present invention, the current equalizing unit 300 can be plugged into the box body 100 .

[0053] It can be understood that the current balancing unit 300 is pluggable and connected to the box body 100. When the current balancing unit 300 needs to be maintained, the current balancing unit 300 can be directly pulled out for cleaning or replacement.

[0054] In some embodiments, the flow balancing unit 300 includes a frame, the sponge layer 302 and the filter layer are both arranged on the frame, and the frame is plugged and matched with the box body 100, so as to realize the pluggable connection between the flow balancing unit 300 and the box body 100. The box body 100 has a second side wall, and a plug-in hole is arranged on the second side wall, and the frame can be inserted into or pulled out of the box body 100 along the plug-in hole. The first side wall 103 is connected to the second side wall and the first side wall 103 is perpendicular to the second side wall.

[0055] A handle is provided at one end of the frame, and the frame can be pulled by the handle to slide in the box body 100 along the length direction of the box body 100 , thereby sliding the frame into or out of the box body 100 .

[0056] In some embodiments of the present invention, the heat exchange fins 201 are arranged along a first direction, and the first direction is a line direction connecting the top of the box body 100 and the bottom of the box body 100 .

[0057] It can be understood that the first direction is essentially the height direction of the box body 100. Since the medium inlet 101 and the medium outlet 102 are respectively arranged at the top and the bottom of the box body 100, the heat exchange plate 201 is arranged along the height direction of the box body 100, so that the cooling medium can move in the vertical downward direction, so that the cooling medium can quickly bring the heat of the heat exchange plate 201 out of the box body 100, thereby avoiding excessive heat in the box body 100.

[0058] In some embodiments of the present invention, the heat exchange fins 201 are in a straight shape.

[0059] In some embodiments of the present invention, the heat exchange fins 201 are wavy.

[0060] It can be understood that the wavy heat exchange fins 201 can have a larger surface area within the same length range, and thus have better heat dissipation performance than the straight heat exchange fins 201 .

[0061] In some embodiments of the present invention, the heat exchange fins 201 are arranged at an angle.

[0062] It is understandable that the inclined setting of the heat exchange plate 201 can slow down the flow speed of the cooling medium on the heat exchange plate 201, thereby making the cooling medium flow on the heat exchange plate 201 for a relatively long time, so that the cooling medium and the heat exchange plate 201 can have enough time to exchange heat.

[0063] In some embodiments, the utility model further provides an electric control assembly, which includes an electric control box and the above-mentioned heat dissipation box 10, the electric control box has an outer shell 20, and the outer shell 20 has a heat dissipation opening. The first side wall 103 of the heat dissipation box 10 is attached to the heat dissipation opening and covers the heat dissipation opening.

[0064] It should be noted that the outer shell 20 is generally made of metal material, which can improve the heat conduction efficiency between the electric control box and the heat dissipation box 10 and improve the heat dissipation effect of the heat dissipation box 10 .

[0065] Generally, the surface area of ​​the first side wall 103 is larger than the opening area of ​​the heat dissipation opening, and the first side wall 103 completely covers the heat dissipation opening. The first side wall 103 is detachably connected to the outer shell 20 by screws.

[0066] It can be understood that the first side wall 103 directly transfers the heat inside the electric control box through the heat dissipation opening, thereby improving the heat dissipation efficiency of the heat dissipation box 10 to the electric control box.

[0067] In some embodiments, the utility model further provides a refrigeration cycle system, which includes a compressor, a condenser 60, an evaporator 70, a gas-liquid separator 80 and the above-mentioned heat dissipation box 10. The inlet of the condenser 60 is connected to the outlet of the compressor, the inlet of the evaporator 70 is connected to the outlet of the condenser 60, the inlet of the gas-liquid separator 80 is connected to the outlet of the evaporator 70, the outlet of the gas-liquid separator 80 is connected to the inlet of the compressor, the medium inlet 101 is connected to the outlet of the evaporator 70, and the medium outlet 102 is connected to the inlet of the gas-liquid separator 80.

[0068] That is, the condensed water of the evaporator 70 is used to exchange heat with the heat dissipation box 10 of the electric control box, thereby improving the heat dissipation efficiency of the heat dissipation box 10 to the electric control box.

[0069] In some embodiments, the utility model further provides an air conditioner, including the above-mentioned heat dissipation box 10. Since the air conditioner includes the heat dissipation box 10 of the above-mentioned embodiment, it has at least some or all of the beneficial effects of the heat dissipation box 10 of the above-mentioned embodiment, which will not be described one by one here.

[0070] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the application concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
