Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of condensers, in particular to a finned condenser for rapid evaporation of condensate. BACKGROUND

[0002] At present, the light business industry is developing rapidly, and the product update iteration speed is accelerating. Energy saving is the main trend of industrial development. Especially in the domestic dairy industry, there is a large demand for open air curtain cabinets every year, and the main terminal storage, display and sales products are whole open air curtain cabinets. This type of product has large heat dissipation, which makes the refrigeration condensate drainage large. Taking a 1.2m length open air curtain cabinet product as an example, it discharges 0.7L of evaporator condensate per hour (about 5℃), and the running power is 1.2kW, which will release a large amount of heat. The operation and management of such products in stores have great challenges.

[0003] At present, the refrigeration system has many problems when in use. Since the compression type refrigeration system circulates air through the condenser fan, the high-temperature and high-pressure refrigerant gas in the condenser is condensed into liquid, and a large amount of heat is discharged at the same time. The larger the refrigerating capacity of the whole cabinet product, the larger the heat discharge, and the store needs to increase the air conditioning system to reduce the heat, resulting in an increase in the energy consumption of the whole store. And the defrosting of the refrigeration product will produce a large amount of low-temperature condensate, which is discharged to the outside of the cabinet through the drain pipe. The whole cabinet has the characteristics of flexible placement, and the condensate is discharged continuously during the whole refrigeration operation. However, subway stations, newly decorated supermarkets and other places do not have the sales scene of hidden drain pipes, and the problem of condensate discharge needs to be solved. In order to solve the problem of condensate discharge, the condensate after evaporation refrigeration is mainly discharged in the following ways: discharged into the evaporation water box inside the condensing unit, and the condensate in the evaporation dish is heated by the condensing pipe of the compressor to evaporate. The water that has not evaporated is discharged. However, in the above-mentioned way, since the condensing pipe is high-temperature refrigerant, if it is soaked in condensate for a long time, once it leaks, it will cause damage to the compressor and may also cause the water to be sucked into the compressor, causing damage to the compressor. SUMMARY

[0004] In view of the above-mentioned problems in the current condensate discharge mode, when the condensing pipe leaks, the compressor is easy to suck in the condensate and cause damage to itself, the present application provides a finned condenser for rapid evaporation of condensate.

[0005] In order to solve the above-mentioned technical problems, the present application adopts the following technical scheme:

[0006] The finned condenser for quick evaporation of condensate water comprises a shell, heat dissipation pipes, a drainage pipe and fins, and the heat dissipation pipes, the drainage pipe and the fins are fixed in the shell. The two sides of the heat dissipation pipes are spirally coiled and form two groups of heat dissipation parts; the drainage pipe is S-shaped coiled and located between the two groups of heat dissipation parts.

[0007] Further, the spiral directions of the two groups of heat dissipation parts are opposite.

[0008] Further, the two groups of heat dissipation parts are a first heat dissipation part and a second heat dissipation part respectively, and a condensing fan is fixed on one side of the shell adjacent to the first heat dissipation part.

[0009] Further, the end opening of the first heat dissipation part is a refrigerant inlet, and the end opening of the second heat dissipation part is a refrigerant outlet.

[0010] Further, the end openings of the first heat dissipation part and the second heat dissipation part are located at the upper part of the shell.

[0011] Further, the connection between the first heat dissipation part and the second heat dissipation part is located at the lower part of the shell.

[0012] Further, the upper end opening of the drainage pipe is a condensate water inlet, and the lower end opening is a condensate water outlet.

[0013] Further, an evaporation dish is fixedly connected to the bottom of the shell, and the lower end opening of the drainage pipe faces into the evaporation dish.

[0014] The beneficial effects of the present application are: the present application utilizes the heat exchange principle of the finned condenser, divides the pipeline of the finned condenser into heat dissipation pipes and drainage pipes, fully utilizes the temperature difference between the low-temperature condensate water and the high-temperature gaseous refrigerant, and realizes quick heat exchange between them, which not only can increase the temperature of the condensate water, speed up the evaporation efficiency to reduce the discharge of the condensate water, but also can make the high-temperature gaseous refrigerant quickly condense into liquid refrigerant, effectively improve the heat exchange efficiency of the finned condenser.

[0017] The application discloses a fin condenser for quick evaporation of condensed water.

[0018] As shown in the drawings, the fin condenser for quick evaporation of condensed water comprises a shell 1, a heat dissipation pipe, a drainage pipe 4, a condensing fan 6 and a plurality of fins, wherein the heat dissipation pipe, the drainage pipe 4 and the plurality of fins are fixed in the shell 1. Figure 1 The left side of the heat dissipation pipe is spirally coiled to form a first heat dissipation part 2. The end opening of the first heat dissipation part 2 is a refrigerant inlet 201 and is fixed on the upper left side of the shell 1. The right side of the heat dissipation pipe is spirally coiled to form a second heat dissipation part 3. The end opening of the second heat dissipation part 3 is a refrigerant outlet 301 and is fixed on the upper right side of the shell 1. The spiral direction of the first heat dissipation part 2 is opposite to that of the second heat dissipation part 3, and the connection between the first heat dissipation part 2 and the second heat dissipation part 3 is located on the lower part of the shell 1. The condensing fan 6 is fixed on the left side of the shell 1 and is adjacent to the first heat dissipation part 2.

[0019] The drainage pipe 4 is spirally coiled and is located between the first heat dissipation part 2 and the second heat dissipation part 3. The upper end opening of the drainage pipe 4 is a condensed water inlet 401 and the lower end opening is a condensed water outlet 402. The bottom of the shell 1 is fixedly connected with an evaporating dish 5, and the lower end opening of the drainage pipe 4 faces the evaporating dish 5.

[0020] In use, high-temperature and high-pressure refrigerant enters the first heat dissipation part 2 through the refrigerant inlet 201, then enters the second heat dissipation part 3 and finally flows out from the refrigerant outlet 301. The refrigerant is fully exchanged with the plurality of fins in the spirally coiled first heat dissipation part 2 and second heat dissipation part 3. The condensing fan 6 drives the air to blow along the direction from the second heat dissipation part 3 to the first heat dissipation part 2, so as to realize heat dissipation of the first heat dissipation part 2 and the second heat dissipation part 3. The condensed water generated by the evaporator evaporates and enters the drainage pipe 4 through the condensed water inlet 401. The condensed water in the drainage pipe 4 is quickly exchanged with the plurality of fins, so as to accelerate the speed of condensation of the refrigerant into low-temperature liquid. The low-temperature condensed water absorbs the heat of the high-temperature gaseous refrigerant after heat exchange and becomes high-temperature condensed water, and then flows into the evaporating dish 5 from the condensed water outlet 402. At this time, the condensed water has a higher temperature after heat exchange, so that the evaporation efficiency of the condensed water is improved and the evaporation speed is accelerated.

[0021] The application utilizes the heat exchange principle of the finned condenser, divides the pipeline of the finned condenser into the heat dissipation pipe and the drainage pipe 4, fully utilizes the temperature difference between the low-temperature condensate water and the high-temperature gaseous refrigerant, makes them quickly exchange heat with each other, can not only improve the temperature of the condensate water, speed up the evaporation efficiency to reduce the discharge of the condensate water, but also can make the high-temperature gaseous refrigerant quickly condense into liquid refrigerant, effectively improves the heat exchange efficiency of the finned condenser, solves the problems that the traditional condensing pipe is easily corroded and leaked by being soaked in the evaporating pan 5, improves the use safety and service life.

[0022] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the skilled in the art within the essential scope of the present application shall also belong to the protection scope of the present application.
