Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat dissipation device, in particular to a heat dissipation device for air conditioner main unit. BACKGROUND

[0002] When the air conditioner works, the compressor sucks the low-temperature and low-pressure refrigerant vapor generated by the evaporator into the cylinder, and the pressure and temperature of the refrigerant are increased after being compressed by the compressor. When the pressure is higher than that in the condenser, the high-temperature and high-pressure refrigerant vapor in the cylinder is transported to the condenser. The high-temperature and high-pressure refrigerant vapor in the condenser exchanges heat with the coolant and condenses into liquid refrigerant. The liquid refrigerant is cooled and decompressed by the expansion valve and then enters the evaporator. After absorbing heat in the evaporator, the refrigerant vapor is vaporized again. The refrigerant vapor is sucked away by the compressor, and the cycle is completed through the processes of compression, condensation, expansion and evaporation.

[0003] During the operation of the air conditioner main unit, especially when the compressor compresses the refrigerant, a large amount of heat is generated, which causes the temperature of the air conditioner main unit to rise rapidly. In order to achieve cooling, a fan is usually provided on the air conditioner main unit. The rotating fan blades suck air from one side of the air conditioner main unit and discharge it from the other side to carry away part of the heat.

[0004] However, during the process of cooling by air flow induced by the fan, the discharged hot air is not guided, which causes the temperature of the air around the fan to gradually rise, and the temperature of the air sucked into the air conditioner main unit also rises, affecting the cooling effect of the fan and the service life of the air conditioner main unit. In particular, when the air conditioner main unit is installed indoors, the indoor temperature rises with the operation of the air conditioner main unit, and the fan cannot achieve the cooling effect. Therefore, the present application proposes a heat dissipation device for air conditioner main unit to overcome the above-mentioned defects. SUMMARY

[0005] The present application aims to solve at least one of the above technical problems in the technical field. To this end, the purpose of the present application is to provide a heat dissipation device for air conditioner main unit, so that the cooling effect is better when the air conditioner main unit operates, and the operating noise of the air conditioner main unit can be reduced.

[0008] According to the air conditioner main unit heat dissipation device, the air inlet channel is formed between the fan air inlet side of the air conditioner main unit and the opposite closed body, the air inlet channel is communicated with the external air and the fan air inlet side, the external air is sucked into the air conditioner main unit from the fan air inlet side through the air inlet channel, heat exchange takes away heat and air is exhausted from the fan air exhaust side, and the temperature of the exhausted air is relatively high; the air deflector arranged obliquely is arranged in the air exhaust direction of the fan air exhaust side, the air exhausted from the fan air exhaust side is guided away from the air inlet of the air inlet channel, so that the air with the relatively high temperature is isolated from the air with the relatively low temperature, and the air sucked into the air conditioner main unit from the fan air inlet side is always the air with the relatively low temperature. Therefore, the cooling effect of the air conditioner main unit is better when the air conditioner main unit operates. Meanwhile, since the air conditioner main unit is installed in the opposite closed body, the operation noise of the air conditioner main unit can be reduced.

[0009] In addition, the air conditioner main unit heat dissipation device can have the following additional technical features.

[0010] Further, the opposite closed body with one side opening is a box with one side opening, the box comprises a bottom plate, a top plate, a first side plate, a second side plate and a third side plate; the upper side of the first side plate is connected with the top plate, and the lower side of the first side plate is connected with the bottom plate which is arranged in the same direction and opposite to the top plate; the left side of the first side plate is connected with the second side plate, and the right side of the first side plate is connected with the third side plate which is arranged in the same direction and opposite to the second side plate.

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] Example 1

[0031] like Figure 1 and Figure 2 As shown, the present invention discloses an air conditioning unit heat dissipation device, which includes a relatively enclosed body 1 with an opening on one side and an air guiding mechanism 2.

[0032] The air conditioner main machine 3 is installed in the relative closed body 1, and the fan 31 of the air conditioner main machine 3 is connected with the relative closed body 1 to form an air inlet channel 4, which is communicated with the outside air and the fan 31.

[0033] The air guide mechanism 2 is installed in the relative closed body 1 and located at the opening side of the relative closed body 1. The air guide mechanism 2 includes an air guide plate 21 arranged obliquely, which is located at the front end of the air outlet direction of the fan 31, and is used to guide the air outlet from the fan 31 to the air inlet of the air inlet channel 4.

[0034] The air conditioner main machine 3 is installed in the relative closed body 1, and the fan 31 of the air conditioner main machine 3 is connected with the relative closed body 1 to form an air inlet channel 4, which is communicated with the outside air and the fan 31.

[0035] In some examples, the relative closed body 1 with one side opening is a box with one side opening, which includes a bottom plate 11, a top plate 12, a first side plate 13, a second side plate 14 and a third side plate 15. The upper side of the first side plate 13 is connected with the top plate 12, and the lower side of the first side plate 13 is connected with the bottom plate 11 arranged in the same direction and opposite to the top plate 12. The left side of the first side plate 13 is connected with the second side plate 14, and the right side of the first side plate 13 is connected with the third side plate 15 arranged in the same direction and opposite to the second side plate 14. The shape of the box is generally matched with the shape of the air conditioner main machine 3.

[0036] In the embodiment, the air guide mechanism 2 further comprises a mounting plate 22 integrally connected with the air guide plate 21 arranged obliquely, and the mounting plate 22 is connected with the second side plate 14 and the third side plate 15 respectively. A support 5 is arranged between the mounting plate 22 and the bottom plate 11. The mounting plate 22 can isolate the air conditioner main unit 3 from the air inlet channel 4, and further prevent the air with high temperature discharged by the fan 41 from entering the air inlet channel 4. The angle between the air guide plate 21 and the mounting plate 22 is adjustable, so that the air guide direction of the air guide plate 21 can be adjusted, and the cooling effect is further improved.

[0037] In the embodiment, the air conditioner main unit 3 is arranged on the mounting plate 22, and the mounting plate 22 and the bottom plate 11 and the air conditioner main unit 3 and the first side plate 13 together form the air inlet channel 4 which is in communication with the fan 31 and the external air respectively; and the air guide plate 21 is arranged obliquely upward.

[0038] The air conditioner main unit 3 and the top plate 12 form an air passing channel 6 which is in communication with the air inlet channel 4, and a one-way valve plate 61 is arranged in the air passing channel 6 to allow air in the air inlet channel 4 to be discharged.

[0039] Embodiment two

[0040] As shown in the drawings, the air conditioner main unit cooling device disclosed by the present application comprises a relatively closed body 1 with one side open and an air guide mechanism 2. Figure 3

[0041] The air conditioner main unit 3 is arranged in the relatively closed body 1, and the fan 31 of the air conditioner main unit 3 and the relatively closed body 1 form an air inlet channel 4, and the air inlet channel 4 is in communication with the external air and the fan 31, and the fan 31 of the air conditioner main unit 3 is located at the open side of the relatively closed body 1.

[0042] The air guide mechanism 2 is arranged in the relatively closed body 1 and located at the open side of the relatively closed body 1. The air guide mechanism 2 comprises an air guide plate 21 arranged obliquely, and the air guide plate 21 is located at the front end of the air discharge direction of the fan 31, and is used for guiding the air discharged by the fan 31 to be away from the air inlet of the air inlet channel 4.

[0043] ​Because an air intake channel 4 is formed between the air intake side of the fan 31 of the air conditioning unit 3 and the relatively enclosed body 1, and the air intake channel 4 is connected to the outside air and the air intake side of the fan 31, the outside air temperature is lower. The outside air is drawn into the air conditioning unit 3 through the air intake channel 4 from the air intake side of the fan 41, heat exchange carries away the heat, and it is discharged from the exhaust side of the fan 31. At this time, the discharged air temperature is higher. An inclined air guide plate 21 is provided in the direction of the air discharged from the exhaust side of the fan 31, which guides the air discharged from the exhaust side of the fan 41 away from the air intake of the air intake channel 4, thereby isolating the higher temperature air from the lower temperature air, ensuring that the air drawn into the air conditioning unit 3 from the air intake side of the fan 31 is always lower temperature air. Therefore, the air conditioning unit 3 has a better cooling effect when it is running. At the same time, because the air conditioning unit 3 is installed in the relatively enclosed body 1, the operating noise of the air conditioning unit 3 can also be reduced.

[0044] In some examples, the relatively enclosed body 1 with an opening on one side is a box-shaped enclosure, which includes a bottom plate 11, a top plate 12, a first side plate 13, a second side plate 14, and a third side plate 15. The upper side of the first side plate 13 is connected to the top plate 12, and the lower side of the first side plate 13 is connected to the bottom plate 11, which is arranged opposite to the top plate 12 in the same direction. The left side of the first side plate 13 is connected to the second side plate 14, and the right side of the first side plate 13 is connected to the third side plate 15, which is arranged opposite to the second side plate 14 in the same direction. The shape of the enclosure typically matches the shape of the air conditioning unit 3.

[0045] In this embodiment, the air guiding mechanism 2 further includes a mounting plate 22 integrally connected to the inclined air guiding plate 21. The mounting plate 22 is connected to the second side plate 14 and the third side plate 15 respectively. The mounting plate 22 can isolate the air conditioning unit 3 from the air inlet channel 4, further preventing the high-temperature air discharged from the exhaust side of the fan 41 from entering the air inlet channel 4. The angle between the air guiding plate 21 and the mounting plate 22 is adjustable, thereby adjusting the air guiding direction of the air guiding plate 21 and further improving the cooling effect.

[0046] The air conditioning unit 3 is placed on the base plate 11. The air conditioning unit 3 and the top plate 12, as well as the air conditioning unit 3 and the first side plate 13, together form the air intake channel 4, which is connected to the air intake side of the fan 31 and the external air respectively; the air guide plate 21 is inclined downward.
