The capillary pore plate can be fixed in the water channel 121 of the water cooling block 12 in a welding mode, and can also be fixedly installed in a screwing or buckling mode, the shape of the capillary pore plate is not specifically limited, the capillary pore plate can be a copper plate, an aluminum plate, a stainless steel plate or a hard metal plate with good heat dissipation effect and good ductility, and the capillary pores on the capillary pore plate can be arranged more densely so as to improve the heat dissipation effect. The water-cooling liquid penetrates each capillary hole of the capillary hole plate when passing through the water channel 121 of the water-cooling block 12 so as to take away heat.
In an alternative embodiment, the capillary orifice is disposed on a side of the water-cooled block 12 adjacent to the electronic control box 13 (not shown). The capillary hole plate is arranged in such a position to increase the contact area between the water cooling liquid flowing through the water cooling block 12 and the electric control box 13, and particularly, the capillary hole plate is close to one side of the electric control box 13 with a heat dissipation surface, so that the heat dissipation effect is better.
In an alternative embodiment, as shown in fig. 5, the water cooling block 12 is attached to the heat dissipating surface of the electronic control box 13. The water cooling block 12 is attached to the heat dissipation surface of the electric control box 13, so that heat dissipation of the electric control box 3 is facilitated, of course, the water cooling block 12 can be away from the electric control box 13 by a certain distance, such as 3mm, 5mm or other numerical values, but the distance is not too large, and the heat dissipation effect of the water cooling block 12 on the electric control box 13 is not affected.
In an alternative embodiment, the water cooling block 12 has one or more grooves (not shown) on the surface contacting the electronic control box 13, and each groove can completely cover at least one power device 115 in the electronic control box 13. Specifically, when one groove is formed in the surface of the water cooling block 12, the most serious important power device 115 can be selected to be completely covered, when a plurality of grooves are formed in the surface of the water cooling block 12, the most serious important power devices 115 can be selected to be completely covered, the depth of the groove can be matched with the height of the corresponding power device 115, and the opening shape of the groove is matched with the shape of the corresponding power device 115, so that the distance between the power device 115 and the groove can be ensured to be as small as possible, and the cooling effect of the water cooling block can be improved.
In an alternative embodiment, as shown in fig. 5, the cold water pipe 14 is arranged to be circuitous on the surface of the heat sink 16. The roundabout arrangement of the cold water pipeline 14 increases the contact area between the cold water pipeline 14 and the heat dissipation device 16, further improves the heat dissipation effect of the water cooling liquid in the cold water pipeline 14, and improves the heat dissipation efficiency of the water cooling liquid flowing in the water cooling block 12 on the power device 115 in the electronic control box 13.
According to a second aspect of the embodiments of the present invention, an air conditioner is provided, which includes the air conditioner outdoor unit 1 described above. As shown in fig. 6, specifically, the outdoor unit 1 and the indoor unit 2 of the air conditioner are connected, when the air conditioner performs cooling, the compressor 11 of the outdoor unit 1 starts to operate, the power device 115 in the electronic control box 13 generates a large amount of heat when the outdoor environment temperature is high, at this time, the water pump controller 19 turns on the water pump 15, the water pump 15 drives the water-cooling liquid in the cold water pipeline 14 to circulate in the cold water pipeline 14, when the water-cooling liquid flows through the water-cooling block 12, the power device 115 in the electronic control box 13 is cooled down to take away the heat generated by the power device 115, at this time, when the water-cooling liquid flowing through the heat dissipation device 16 due to the temperature rise of the heat absorbed by the power device 115 passes through the heat dissipation device 16, the heat dissipation device 16 absorbs the heat of the water-cooling liquid to cool the water-cooling liquid, so as to ensure that the water-cooling liquid is always in a low temperature state, and the, the temperature of the heat sink 16 is reduced. A four-way valve 113, a three-way valve 112, a two-way valve 111 and an electronic expansion valve 114 are arranged on a refrigerant pipeline 18 between the compressor 11 and an evaporator 21 in the indoor unit 2 of the air conditioner, the outdoor fan 17 is used for discharging high-temperature and high-pressure gas discharged by the indoor unit 2 of the air conditioner to the outside and simultaneously radiating heat for the condenser 110, and the indoor fan 22 is used for supplying air to and discharging air from the indoor unit 2 of the air conditioner, so that the whole air conditioner cools a power device 115 in the electronic control box 13 in the refrigeration process.
It is to be understood that the present invention is not limited to the procedures and structures described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the invention is limited only by the appended claims.
