Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 and 2, the heat dissipating device for an outdoor cabinet of the present invention comprises an outer casing 1 having an outer air inlet 11, an outer air outlet 12, an inner air inlet 13 and an inner air outlet 14, and an inner casing 2 located in the middle of the outer casing 1, wherein the inner casing 2 is divided by an obliquely disposed partition 21 into an outer circulation chamber 22 communicating with the outer air inlet 11 and an inner circulation chamber 23 communicating with the inner air inlet, the outer circulation chamber 22 communicates with an upper chamber 15 located above the inner casing 2 and provided with the outer air outlet 12, an outer circulation fan 3a is disposed in the upper chamber 15, the inner circulation chamber 23 communicates with a lower chamber 16 located below the inner casing 2 and provided with the inner air outlet 14, an inner circulation fan 3b is disposed in the lower chamber 16, a first heat exchange tube 4 and a second heat exchange tube 5 are disposed in the inner casing 2, a condensation section 41 of the first heat exchange tube 4 is located inside the outer air inlet 11, and an evaporation section 42 is located on an inlet side of the inner circulation fan 3b, the condensation section 51 of the second heat exchange pipe 5 is positioned at the inlet side of the external circulation fan 3a, and the evaporation section 52 is positioned at the inner side of the inner air inlet 13. The partition plate 21 allows the outer circulation chamber 22 and the inner circulation chamber 23 not to communicate with each other. The inner air inlet 13 and the inner air outlet 13 of the heat dissipation device are both connected to an outdoor cabinet. When the air conditioner works, outdoor air passes through the outer air inlet 11, the outer circulation cavity 22, the upper cavity 15 and the outer air outlet 12 in sequence under the action of the outer circulation fan 3a and returns to the outdoor environment, and air in the cabinet passes through the inner air inlet 13, the inner circulation cavity 23, the lower cavity 16 and the inner air outlet 14 in sequence under the action of the inner circulation fan 3b and returns to the indoor environment. In the process, the refrigerant in the first heat exchange tube 4 absorbs the heat of the air in the cabinet from the evaporation section 42 to become a gas state, then the refrigerant enters the condensation section 41 to emit heat to the outdoor air, and then the refrigerant turns into a liquid state and returns to the evaporation section 42; meanwhile, the refrigerant in the second heat exchange tube 5 absorbs the heat of the air in the cabinet from the evaporation section 52, turns into a gas state, then enters the condensation section 51 to emit heat to the outdoor air, and then turns into a liquid state to return to the evaporation section 52. The condensing section 41 and the evaporating section 42 of the first heat exchange tube 4 and the condensing section and the evaporating section 42 of the second heat exchange tube 5 are provided with fins for increasing the heat exchange area, so that when forced convection of a fan is performed, heat can be transferred to a refrigerant when hot air of the internal circulation passes through the fins, and then the heat is transferred to cold air of the external circulation. The utility model can use the two heat exchange tubes 4 and 5 to accelerate the heat exchange efficiency between the internal and external circulating air, and can help the heating components in the outdoor cabinet to be quickly cooled under the condition of saving energy.
As shown in fig. 1 and 2, an air filter 6 is provided inside the external air inlet 11. The air filter 6 can prevent impurities in outdoor air from entering the device, and has the effects of insect prevention, dust prevention and particle prevention.
As shown in fig. 1, the upper chamber 15 is provided with a diversion drain hole 17 above the air filter 6 to communicate the external circulation chamber 22 with the upper chamber 15, and the housing 1 is provided with a drain hole 18 below the air filter 6. The condensation section 41 of the first heat exchange pipe 4 is located inside the air filter 6, and if the outdoor air has more moisture and is liquefied during heat exchange, the outdoor air can be discharged to the lower part of the shell 1 by the diversion drain hole 17 and the drain hole 18, so that the corrosion of the shell 1 by the accumulated moisture can be inhibited.
As shown in fig. 2, the housing 1 is provided with a side suction groove 19 for taking out the air filter. After the dust on the air filter 6 is accumulated to a certain degree, the dust can be drawn out from the side for cleaning or replacement, and the operation is convenient.
As shown in fig. 2, the first heat exchanging pipe 4 is fixed obliquely in the housing 1. When the first heat exchange tubes 4 are obliquely arranged, the condensing section 41 and the evaporating section 42 are inevitably higher on one side than on the other side. The lower side is used for collecting liquid downwards, and the higher side is used for evaporating upwards, so that the refrigerant can directionally circulate. The second heat exchange tube 5 can also adopt an inclined method to assist the directional circulation of the refrigerant.
As shown in fig. 1 and 2, the outer air outlet 12 and the inner air outlet 14 are provided with a plurality of uniform flow holes. The flow equalizing holes can disperse air into small air flow for uniform air outlet, and help to reduce air turbulence and working noise.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
