In order to dissipate the heat generated during the operation of the air conditioner, the existing air conditioner mainly adopts the method of adding a fan, which is rotated by the fan. Air convection to achieve the purpose of cooling fins. When the temperature of the application is high and the temperature difference between the air formed by convection and the heat sink is small, the heat dissipation capacity of the heat sink is greatly reduced, so that the temperature of the electronic components connected to the heat sink will rise sharply, thereby reducing the temperature of the electronic components.

As shown in Figure 1, an air conditioner provided by an embodiment of the present invention includes: an indoor unit 1, an outdoor unit 2, a first water pipe 71, a first cooling fin 61 and a first drain pipe 101, wherein:

The indoor unit 1 is provided with an evaporator 3 and a water storage container 4 located below the evaporator 3 for collecting condensed water. During the operation of the air conditioner, the refrigerant in the evaporator 3 of the indoor unit 1 exchanges heat with the surrounding air And absorb the heat in the surrounding air to reduce the temperature of the indoor air. When the air around the evaporator 3 is cooled, the moisture in the air will condense into condensed water. condensation.

The first cooling fin 61 is connected with the first heating element 51 for dissipating the heat generated by the first heating element 51 to reduce the temperature of the first heating element 51; the water inlet of the first water pipe 71 is connected with the water storage container 4 , to lead out the condensed water collected in the water storage container 4, the first water receiving pipe 71 is made of plastic or sheet metal material.

The first cooling fin 61 is provided with a plurality of first cooling pipes 610, and the water outlets of the first water receiving pipe 71 are respectively connected to the inlets of a plurality of first cooling pipes 610 through the first flow divider 81, and the first drain pipe 101 passes through the first The confluence 91 is respectively connected to the outlets of the plurality of first heat dissipation pipes 610 , and the first confluence 91 and the first drain pipe 101 are used to collect water passing through the first heat dissipation pipes 610 and discharge it out of the outdoor unit. Both the first diverter 81 and the first confluence 91 are made of plastic or rubber.

When the air conditioner is in the cooling mode, the first heating element 51 of the outdoor unit 2 will generate a large amount of heat due to energization. The heat generated by the heating element 51 is often difficult to dissipate, causing the temperature of the first heating element 51 to rise, and the maximum temperature can reach 70-80°C. The air conditioner provided in this embodiment uses the condensed water produced by the condenser 3 of the indoor unit 1. The temperature of the condensed water is generally 10°C. Especially when the operating temperature is high, the temperature of the condensed water is higher than that of the first cooling fin. The temperature of 61 is much lower, so that when the condensed water passes through the first heat pipe 610 of the first heat sink 61, it will have an effective heat exchange with the first heat sink 61, taking away most of the heat of the first heat sink 61, and passing through the first heat sink 61. After the water in a cooling pipe 610 is combined by the first confluencer 91 , it is discharged from the outdoor unit through the first drain pipe 101 . There are multiple first heat dissipation pipes 610 in this embodiment, and the first water receiving pipe 71 divides the condensed water collected in the water storage container 4 through the first flow divider 81 and then guides them into each first heat dissipation pipe 610, which greatly increases condensation. The heat exchange area between water and the first heat sink 61 can quickly and effectively reduce the temperature of the first heat sink 61, and then effectively reduce the temperature of the first heat generating element 51 connected to the first heat sink 61, avoiding the first heat generating element The temperature of 51 is too high, which effectively prevents the first heating element from being damaged due to too high temperature. The invention has a simple structure, only needs to use water pipes, diverters and confluences, and has low cost, and there is no possibility of mechanical failure; the invention uses condensed water and cooling fins to dissipate heat, which can quickly cool down and has a good cooling effect.

Preferably, the second water receiving pipe 72 is made of plastic or sheet metal. Both the second diverter 82 and the second confluence 92 are made of plastic or rubber material.

The cooling process of the second heating element 52 is the same as the cooling process of the first heating element, and will not be repeated here. By cooling the second heating element 52 of the indoor unit 1, the influence of the heat generated by the indoor unit 1 on the indoor temperature is reduced, and the indoor temperature is guaranteed to be lowered as much as possible, which can effectively save energy and avoid the second heating of the indoor unit 1. The heating element 52 is lost due to excessive temperature.

The first cooling fins 61 of the air conditioner in this embodiment can be multiple, and the plurality of first cooling fins 61 are arranged on the first heat generating element 51 at intervals, thus the heat dissipation effect can be further enhanced, and the first cooling fins 61 can be further reduced. The temperature of the heating element 51 prolongs the service life of the first heating element 51 . The first heat sink 61 can be disposed on the side, top or bottom of the first heating element 51 , which has the advantages of convenient installation, low cost and obvious and reliable effect. Similarly, the second heat sink can also be a plurality of second heat sinks 62, and a plurality of second heat sinks 62 are arranged on the second heat generating element 52 at intervals, and the second heat sink 62 is arranged on the second heat generating element 52. Either the side or the top or the bottom of the member 52 is acceptable.

Preferably, N=5. So that the amount of condensed water entering the first heat dissipation pipe 610 and the second heat dissipation pipe 620 through the first flow divider 81 and the second flow divider 82 is sufficient, and will not be too much to cause waste, so that the condensed water and the first heat dissipation fin 61 The heat exchange effect with the second heat sink 62 is better and the waste of condensed water is avoided, the heat exchange efficiency is further improved, and the heat dissipation capacity of the first heat sink 61 and the second heat sink 62 is improved. It should be noted that the structure of the branch pipe and the confluence pipe can be the same, and the directions are reversed during use.

Further, the inner diameters of the first heat dissipation pipe 610 and the second heat dissipation pipe 620 are both set to 3mm, and the first heat dissipation pipe 610 and the second heat dissipation pipe 620 are made of copper pipes, thereby further enhancing the condensed water and the first heat dissipation fins. 61 The heat exchange effect of the second heat sink 62 makes the heat dissipation capability of the first heat sink 61 and the second heat sink 62 stronger.

It should be noted that the first water receiving pipe 71 of the outdoor unit 2 may also be connected to the second drain pipe 102 .
