Technical Field

[0001] The present disclosure relates to the technical field of air conditioning, and in particular to a heat dissipation and waterproof structure, an electric control box and an air conditioner. Background Art

[0002] The outdoor unit of the air conditioner is generally installed outdoors. The outdoor unit is equipped with components such as a compressor, a fan, and an electronic control box. In summer, the outdoor temperature is high. After being exposed to the sun for a long time, the temperature inside the compressor cavity rises sharply, causing the operating temperature of the components in the electronic control box to exceed the standard, thereby affecting the life of the components. In the related art, ventilation and heat dissipation holes are provided on the electronic control box or the wind-proof vertical plate to reduce the temperature of the components in the electronic control box. However, in stormy weather, rainwater can enter the electronic control box and the compressor cavity through the ventilation and heat dissipation holes, accelerating the aging of components and corrosion of circuit boards.

[0003] It can be seen that how to reduce the temperature of components in the electronic control box while preventing rainwater from entering the components in the electronic control box and the compressor cavity is a problem that researchers are currently concerned about. Summary of the invention

[0004] The problem solved by the present disclosure is how to prevent rainwater from entering the components of the electric control box and the compressor cavity while reducing the temperature of the components in the electric control box.

[0005] In order to solve the above problems, the present disclosure provides a heat dissipation and waterproof structure on the one hand, which is used for the electrical control box of the air conditioner. The heat dissipation and waterproof structure includes a double-layer partition 1 and a bottom plate 6. The double-layer partition 1 includes a first grille hole 2 and a second grille hole 3 which are staggered. The first grille hole 2 is arranged on the air outlet side partition of the double-layer partition 1, and the second grille hole 3 is arranged on the air inlet side partition of the double-layer partition 1.

[0006] Therefore, the double-layer grille holes are staggered to achieve heat dissipation and waterproof effect.

[0007] Optionally, the first grille holes 2 are higher than the second grille holes 3 .

[0008] Optionally, the projection of the first grille hole 2 on the air inlet side partition is on one side of the air inlet side partition, and the second grille hole 3 is on the other side of the air inlet side partition.

[0009] Thus, the positions of the first grille holes and the second grille holes are staggered up and down and / or left and right, thereby ensuring heat dissipation and waterproofing functions.

[0010] Optionally, the height between the bottom of the second grille hole 3 and the bottom plate 6 is not less than 3 mm.

[0011] Thus, rainwater accumulated in the double-layer partition is prevented from entering into the components (for example, the compressor chamber) located on one side of the air inlet-side partition through the second grille holes.

[0012] Optionally, the first grille holes 2 and / or the second grille holes 3 are provided with wind guide angles.

[0013] This speeds up the gas flow and improves the heat dissipation rate.

[0014] Optionally, the bottom plate 6 is arranged to be inclined relative to a horizontal plane.

[0015] Optionally, drainage holes 4 are provided in the area of ​​the bottom plate 6 at a lower height from the ground.

[0016] As a result, rainwater in the double-layer partition is discharged through the drainage holes, thereby improving the waterproof effect.

[0017] Optionally, the heat dissipation and waterproof structure further includes: wind guiding ribs 5, and the wind guiding ribs 5 are provided with an inclination.

[0018] As a result, the speed at which gas flows into the air inlet side baffle is further accelerated, thereby improving the heat dissipation speed.

[0019] Optionally, the top of the heat dissipation and waterproof structure is configured as an open structure.

[0020] Optionally, the number of the first grille holes 2 is at least 2, and / or the number of the second grille holes 3 is at least 2.

[0021] Therefore, the number of grille holes is set to be no less than 2 to improve the heat dissipation speed.

[0022] Another aspect of the present disclosure provides an electric control box, which includes the heat dissipation and waterproof structure as described above, and is used for an air conditioner.

[0023] The advantages of the electric control box and the above-mentioned heat dissipation and waterproof structure over the prior art are the same, which will not be repeated here.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] Figure 1This is a schematic diagram of an application scenario of the heat dissipation and waterproof structure provided by an embodiment of the present disclosure. Figure 1 , and describe the application scenario in detail.

[0043] Figure 1 The application scenario shown is an outdoor unit of an air conditioner, which includes a fan cavity 7, a compressor cavity 8, a condenser 9, a bottom panel 10, a controller 11, and an electric control box 12. A fan is arranged in the fan cavity 7, and a compressor is arranged in the compressor cavity 8. The fan cavity 7 and the compressor cavity 8 are arranged adjacent to each other in the outdoor unit, and the condenser 9 is arranged at the top of the outdoor unit.

[0044] The compressor absorbs the heat at the low-pressure area end of the air conditioner into the refrigerant, and then sends the heat to the high-pressure area end and radiates it. Therefore, a large amount of heat is generated in the compressor chamber 8. If the heat cannot be radiated in time, the life of the compressor, the controller 11 and the electric control box 12 will be affected.

[0045] In the disclosed embodiment, the electrical control box 12 is arranged between the fan cavity 7 and the compressor cavity 8, and a heat dissipation and waterproof structure is arranged in the electrical control box 12. The gas in the compressor cavity 8 flows into the fan cavity 7 through the heat dissipation and waterproof structure, thereby taking away a large amount of heat, and can also prevent rainwater from flowing into the compressor cavity 8 and the electrical control box 12 through the heat dissipation and waterproof structure, thereby improving the life of the compressor, controller 11 and electrical control box 12.

[0046] It should be noted that Figure 1 The examples shown are merely examples of application scenarios to which the embodiments of the present disclosure can be applied, in order to help those skilled in the art understand the technical content of the present disclosure, but do not mean that the embodiments of the present disclosure cannot be used in other devices, systems, environments or scenarios.

[0047] Embodiment 1:

[0048] This embodiment provides a heat dissipation and waterproof structure, which is used, for example, Figure 1 The electric control box 12 in the application scenario shown. Figure 2 , while combining Figure 3A-Figure 5 , the heat dissipation and waterproof structure in this embodiment is described in detail.

[0049] like Figure 2 As shown, the heat dissipation and waterproof structure comprises a double-layer partition 1 and a bottom plate 6. The double-layer partition 1 comprises a first grille hole 2 and a second grille hole 3 which are staggered. The first grille hole 2 is arranged on the air outlet side partition of the double-layer partition 1, and the second grille hole 3 is arranged on the air inlet side partition of the double-layer partition 1. The bottom plate 6 is arranged at the bottom of the double-layer partition 1 and connects the air inlet side partition and the air outlet side partition.

[0050] Furthermore, the heat dissipation waterproof structure may be provided with a left side plate and a right side plate on its left and right sides respectively, the left side plate is connected to the air inlet side baffle plate and the air outlet side baffle plate on the left side of the heat dissipation waterproof structure, and the right side plate is connected to the air inlet side baffle plate and the air outlet side baffle plate on the right side of the heat dissipation waterproof structure. The heat dissipation waterproof structure may also be provided with no side plates on its left and right sides, and the air inlet side baffle plate and the air outlet side baffle plate are connected only through the bottom plate.

[0051] In this embodiment, combined with Figure 1 The outdoor unit of the air conditioner in the scene shown illustrates the heat dissipation and waterproof structure. It can be understood that the heat dissipation and waterproof structure can also be used in other structures with heat dissipation and waterproof requirements. Figure 1 In the outdoor unit in the application scenario shown, the air outlet side partition is located on the fan cavity side of the outdoor unit, and the air inlet side partition is located on the compressor cavity side of the outdoor unit.

[0052] The staggered setting means that the first grille hole 2 and the second grille hole 3 do not directly correspond to each other, so as to prevent rainwater from directly entering through the first grille hole 2 and the second grille hole 3. Figure 1 In the electric control box and the compressor cavity in the scene shown, the first grille hole 2 and the second grille hole 3 can still form a heat dissipation channel, thereby reducing the temperature of the components in the electric control box and the compressor cavity and preventing rainwater from entering the components in the electric control box and the compressor cavity through the grille holes.

[0053] In this embodiment, a staggered double-layer partition board 1 is provided. Specifically, the first grille holes 2 are higher than the second grille holes 3, so that the positions of the first grille holes 2 and the second grille holes 3 are staggered up and down.

[0054] In this embodiment, another staggered double-layer partition 1 is provided. Specifically, the projection of the first grille hole 2 on the air inlet side partition is on one side of the air inlet side partition, and the second grille hole 3 is on the other side of the air inlet side partition, so that the positions of the first grille hole 2 and the second grille hole 3 are staggered left and right.

[0055] In this embodiment, another staggered double-layer partition 1 is provided. Specifically, the first grille hole 2 is higher than the second grille hole 3, and the projection of the first grille hole 2 on the air inlet side partition is on one side of the air inlet side partition, and the second grille hole 3 is on the other side of the air inlet side partition, so that the positions of the first grille hole 2 and the second grille hole 3 are staggered up and down and left and right. The position of the first grille hole 2 in the electric control box is as shown in FIG. Figure 3A As shown, the position of the second grille hole 3 in the electric control box is as follows Figure 3B See Figure 3A and 3B It can be seen that the first grille hole 2 is located at the upper position of the air outlet side partition of the double-layer partition 1 and is close to the outer side of the air outlet side partition, and the second grille hole 3 is located at the lower position of the air inlet side partition of the double-layer partition 1 and is close to the inner side of the air inlet side partition.

[0056] The heat dissipation and waterproof structure is used for Figure 1 In the outdoor unit in the scenario shown, the position of the first grille hole 2 on the fan cavity side and the position of the second grille hole 3 on the compressor cavity side are staggered up and down and left and right, thereby ensuring that the hot air on the compressor cavity side enters the fan cavity side through the staggered second grille hole 3 and the first grille hole 2, thereby achieving the heat dissipation function, and preventing rainwater from entering the compressor cavity side through the first grille hole 2 and the second grille hole 3, thereby achieving the waterproof function.

[0057] In this embodiment, the number of the first grille holes 2 is at least 2, and / or the number of the second grille holes 3 is at least 2. By providing a larger number of first grille holes 2 and second grille holes 3, the heat dissipation speed is guaranteed.

[0058] In this embodiment, the height between the bottom of the second grille hole 3 and the bottom plate 6 is not less than 3 mm. When a small amount of rainwater enters the double-layer partition 1, the rainwater cannot enter through the second grille hole 3. Figure 1 The compressor cavity in the illustrated scenario.

[0059] In this embodiment, the bottom plate 6 is inclined relative to the horizontal plane. Furthermore, the bottom plate below the second grille hole 3 is higher than the bottom plate below the first grille hole 2, forming an inclined bottom plate 6. The heat dissipation and waterproof structure is used for Figure 1 In the scenario shown, the bottom plate 6 located inside the indoor unit is inclined toward the condenser side, and the bottom plate 6 located outside the indoor unit is inclined toward the bottom panel side, as shown in FIG. Figure 5 shown.

[0060] When no side panels are provided on the left and right sides of the heat dissipation waterproof structure, water entering the heat dissipation waterproof structure can flow out through the side edge of the lower side of the bottom plate 6 .

[0061] In this embodiment, a drainage hole 4 is provided on the area of ​​the bottom plate 6 at a lower height from the ground. When side panels are provided on the left and right sides of the heat dissipation waterproof structure, the left and right sides are blocked by the side panels. At this time, water entering the heat dissipation waterproof structure can be discharged through the drainage hole 4.

[0062] See also Figure 4A and 4B , Figure 4A A schematic diagram showing the positions of the drain hole 4 and the first grille hole 2 is shown. Figure 4B A schematic diagram showing the positions of the drainage hole 4 and the second grille hole 3 is shown.

[0063] See also Figure 4A The drainage hole 4 is arranged on the area where the bottom plate 6 is lower than the ground. Figure 1 In the scenario shown, further, the drainage hole 4 is arranged on the fan cavity side, which can ensure that rainwater discharged from the drainage hole 4 will not enter the compressor cavity.

[0064] See also Figure 4B It can be seen that the bottom of the second grille hole 3 is higher than the drainage hole 4. When the bottom plate 6 is an inclined surface, the height of the second grille hole 3 from the drainage hole 4 can be further increased, further preventing rainwater in the double-layer partition 1 from entering the compressor cavity, and further improving the waterproof effect of the heat dissipation waterproof structure.

[0065] In this embodiment, the first grille hole and the second grille hole are staggered on the double-layer partition plate to achieve heat dissipation and waterproof function. Drainage holes are provided, an inclined bottom plate is provided, and the height between the second grille hole and the bottom plate is not less than 3 mm, which further improves the waterproof effect.

[0066] Embodiment 2:

[0067] This embodiment provides a heat dissipation and waterproof structure. Compared with the above embodiment, in this embodiment, the first grille hole 2 and / or the second grille hole 3 are provided with a wind guide inclination angle, and the heat dissipation and waterproof structure is also provided with a wind guide rib 5, and the wind guide rib 5 has an inclination. Fig. 6A It can be seen that the air guide ribs 5 surround the first grille holes 2 and / or the second grille holes 3, so that the gas enters the second grille holes 3 through the air guide ribs 5, and / or the gas flowing out of the first grille holes 2 enters the air guide ribs 5. Figure 1 The fan cavity side in the scene shown accelerates the gas circulation speed. Figure 6B It can be seen that the air guide inclination angle makes the hole spacing in the second grille holes 3 gradually increase along the gas flow direction, and the slope makes the spacing surrounded by the air guide ribs 5 around the second grille holes 3 gradually decrease along the gas flow direction.

[0068] Figure 7 A schematic diagram of the gas flow in a heat dissipation and waterproof structure provided by an embodiment of the present disclosure. Figure 7 It can be seen that the heat dissipation and waterproof structure is used Figure 1 In the scenario shown, the gas flow direction in the embodiment of the present disclosure is: the hot gas in the compressor cavity flows through the second grille holes 3 and the first grille holes 2 in sequence and then reaches the fan cavity.

[0069] In this embodiment, the first grille hole 2 and / or the second grille hole 3 are configured as grille holes with an air guide inclination angle, and a circle of inclined air guide ribs 5 are arranged around the first grille hole 2 and / or the second grille hole 3, which can accelerate the speed at which the gas in the compressor cavity flows into the fan cavity and improve the heat dissipation speed.

[0070] In this embodiment, the top of the heat dissipation and waterproof structure is set as an open structure. Figure 1 In the scenario shown, the radiator reference edge 13 of the air conditioner can be used to cover the opening structure. The opening structure at the top of the heat dissipation waterproof structure is as shown in FIG. Fig. 8A As shown, the heat sink reference edge 13 is as shown in Figure 8B As shown, the radiator is covered on the electric control box so that the radiator reference edge 13 also covers the opening structure of the heat dissipation waterproof structure, as shown in FIG. Figure 8C shown.

[0071] In this embodiment, the top of the heat dissipation waterproof structure is set as an open structure and covered with a radiator reference edge 13 with heat dissipation performance, which can further enhance the heat dissipation effect of the heat dissipation waterproof structure.

[0072] The disclosed embodiment further provides an electric control box, which includes the heat dissipation and waterproof structure as described in the above-mentioned embodiments 1 to 2, and the electric control box is used for an air conditioner.

[0076] To sum up, in this embodiment, the first grille hole and the second grille hole are staggered on the double-layer partition plate to achieve heat dissipation and waterproof function at the same time, and drainage holes are provided, an inclined bottom plate is provided, and the height between the second grille hole and the bottom plate is not less than 3 mm, which further improves the waterproof effect, and an air guide inclination angle is set for the first grille hole 2 and / or the second grille hole 3, and air guide ribs are provided, and the top opening structure is covered with the radiator reference edge, which further improves the heat dissipation effect.
