Abstract
Description
Technical Field
[0001] The utility model relates to the field of refrigeration, in particular to a condenser. Background Art
[0002] When the air-conditioning system is working, the condenser will generate a lot of heat. In order to improve the heat exchange effect, the condenser needs to be effectively cooled. At present, the condenser is usually cooled and cooled by a cooling fan. Due to the influence of the condenser heat, the surrounding environment temperature of the cooling fan is relatively high. The hot air blown by the cooling fan cools the condenser, and the cooling effect is general.
[0003] In addition, the condensed water generated by the air conditioning refrigeration system is usually discharged directly. For example, in the Chinese invention patent application "A Heat Pump Type Waste Heat Recovery Fresh Air Unit" with patent application number CN201310350786.5 (publication number CN103398430A), a fan unit is disclosed. After the condensed water drips on the evaporator and falls on the water receiving tray, it is injected into the rotating nozzle by the condensed water pump. Finally, the condensed water is collected in the water receiving tank four and discharged out of the machine through the condensed water pipe. The equipment is also equipped with a water receiving tray, a condensed water pipe and a condensed water pump, which increases material costs and labor costs. The water receiving tray and the condensed water pipe will age and fail after long-term use, reducing the user experience; and if the external discharge position is unreasonable, it will cause long-term erosion of the user's external wall and dripping in the external environment. If it is in a mobile air conditioner, the condensed water is collected in the water box and needs to be cleaned regularly, which is time-consuming and labor-intensive. It can be seen that the existing air conditioning refrigeration system does not make effective use of condensed water. Utility Model Content

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0022] like Figure 1-3 As shown, a condenser of this embodiment includes a pipeline 1, a water pump 2, an exhaust valve 3, a baffle 4 and a heat sink 5.
[0023] Among them, the pipeline 1 is a tortuous coil structure, and the pipeline 1 has an inner ring 8 and an outer ring 9 which are not connected to each other in the radial direction, the condensate channel 11 is arranged in the inner ring 8, and the refrigerant channel 12 is arranged in the outer ring 9. Of course, the condensate channel 11 can also be arranged in the outer ring 9, and the refrigerant channel 12 can be arranged in the inner ring 8. However, compared with the condensate treatment method in which the condensate is distributed on the surface of the condenser, the condensate channel 11 is arranged in the inner ring 8, and the direction of the condensate is more controllable, which can reduce the surface corrosion of the condensate on the condenser.
[0024] An air passage 13 is provided outside the pipe 1. The refrigerant passage 12 has a refrigerant passage inlet 12a and a refrigerant passage outlet 12b. After the compressor works, the high-temperature refrigerant enters the refrigerant passage 12 from the refrigerant passage inlet 12a to achieve heat exchange inside and outside the pipe 1.
[0025] A water pump 2 is provided at the inlet 11a of the condensate channel for driving the condensate to flow in the condensate channel 11. Several exhaust valves 3 are provided in the condensate channel 11 for discharging water vapor and / or air in the condensate channel 11, which can reduce the loss of heat exchange area. The exhaust valve 3 is provided at the turning point of the coil structure to achieve the maximum heat exchange area between the refrigerant and the water. Finally, the water in the condenser is heated to near boiling, so as to achieve zero discharge of condensate water later.
[0026] Of course, in the absence of condensed water, the heat exchange between the refrigerant and the air is not affected. In the presence of condensed water, the condensed water and the air cool the refrigerant at the same time.
[0027] In this embodiment, the inner ring inner wall 81 of the pipeline 1 is provided with a baffle 4 extending inward, and the height of the baffle 4 is less than the height of the inner ring 8. There are multiple baffles 4, and the multiple baffles 4 extend inward and are radially staggered to form a circuitous condensate channel 11. The inner ring outer wall 82 of the pipeline 1 is provided with first fins 6 for heat dissipation that are distributed circumferentially along the inner ring outer wall 82.
[0028] The outer ring inner wall 91 of the pipe 1 is provided with concave-convex parts 7 which are spaced apart along the circumference of the outer ring inner wall 91 and are used to increase the heat exchange area. The concave-convex parts 7 are internal thread strengthening pipes. The outer ring outer wall 92 of the pipe 1 is provided with heat sinks 5 which are second fins spaced apart along the circumference of the outer ring outer wall 92 of the pipe 1. The baffles 4, the first fins 6 and the heat sinks 5 can further enhance the heat exchange.
[0029] The condensate channel inlet 11a and the refrigerant channel outlet 12b are located at one end of the pipe 1 and at the top of the coil structure. The condensate channel outlet 11b and the refrigerant channel inlet 12a are located at the other end of the pipe 1 and at the bottom of the coil structure. In this way, the condensate in the condensate channel 11 and the refrigerant in the refrigerant channel 12 flow in opposite directions, which can achieve a higher heat transfer coefficient.
