Description

Technical Field

[0001] The utility model relates to the technical field of component arrangement inside a refrigeration device shell, in particular to a high-efficiency heat exchange refrigeration device. Background Art

[0002] The refrigeration system usually includes several parts, such as a compressor, a condenser, an expansion valve and an evaporator. The condenser can convert gas or vapor into liquid and transfer the heat in the tube to the air near the tube in a very fast way. The working process of the condenser is an exothermic process, so the temperature of the condenser is relatively high. The outer casing structure of the traditional condenser is usually set as a rectangle, and the condenser tube is set as a straight tube connected by elbows at both ends along the length of the casing, so that the condenser is set to have air intake on one or two sides, and the cooling fan is set on one side of the casing for heat dissipation. When installing the refrigeration unit, the condenser and the compressor are installed separately, and then the condenser tube is connected to the compressor.

[0003] Although the traditional condenser can perform basic heat exchange functions by air intake on one or two sides, it still has the following defects:

[0004] 1. The traditional condenser is set in a rectangular shape. The size of the whole machine is relatively large. It only has one or two sides for air intake, and the windward area is small. In addition, the resistance of the fins is large when the air enters, so the air intake volume is small, resulting in low heat exchange efficiency and unsatisfactory cooling effect;

[0005] 2. The cooling fan is set on one side of the casing. Due to the limitation of small air intake, in order to achieve a better air intake, a cooling fan with larger power is needed to meet the heat dissipation requirements of the condenser, but it will also cause greater losses;

[0006] 3. Since the condenser and the compressor are set separately, the cooling fan on the condenser cannot dissipate heat for the compressor at the same time, causing the compressor to easily overheat and be damaged. Utility Model Content

[0034] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0035] like Figure 1-5 As shown, a high-efficiency heat exchange refrigeration equipment is used for bending the edge of a metal sheet, for example, processing it into a condensing panel assembly suitable for mutual installation with other parts. The high-efficiency heat exchange comprises a heat exchange component 10, a compressor 20, a radiator 30, a filter 40 and a base 53, wherein the heat exchange component 10 has heat exchange fins 101 and a cylindrical heat exchanger 102, and the cylindrical heat exchanger 102 is formed by bending a condenser tube group 1021, and the condenser tube group 1021 is spirally bent in the vertical direction to form a cylindrical cylindrical heat exchanger 102 with a hollow portion 1025.

[0036] The cylindrical heat exchanger 102 is placed with the hollow portion 1025 facing vertically upward during daily use. The heat exchange fins 101 are provided with a plurality of fins, and the plurality of heat exchange fins 101 are arranged in a vertical direction, so that the heat exchange fins 101 are extended in the axial direction of the cylindrical heat exchanger 102 .

[0037] When the heat exchange fins 101 and the cylindrical heat exchanger 102 are installed, a plurality of heat exchange fins 101 are arranged in parallel in the circumferential direction of the cylindrical heat exchanger 102, and the condenser tube group 1021 of the cylindrical heat exchanger 102 is connected through each heat exchange fin 101. The plurality of heat exchange fins 101 are assembled around the cylindrical heat exchanger 102 and inserted with the condenser tube group 1021, so that the plurality of heat exchange fins 101 form an annular windward portion 1027 around the cylindrical heat exchanger 102, so that air can enter the hollow portion 1025 through the gaps between the plurality of heat exchange fins 101 around the cylindrical heat exchanger 102.

[0038] The radiator 30 comprises a cooling fan 301, a cover plate 302 and a protective cover 303, wherein the cover plate 302 is arranged in a circular ring shape, the protective cover 303 is arranged on the top of the cover plate 302 and covers the circular hole in the middle of the cover plate 302, the cooling fan 301 is arranged in the circular hole in the middle of the cover plate 302 and is fixedly connected to the protective cover 303, so that the cooling fan 301 is installed above the hollow portion 1025 of the cylindrical heat exchanger 102 through the cover plate 302 and the protective cover 303.

[0039] The cooling fan 301 is disposed at the top of the cylindrical heat exchanger 102. The cooling fan 301 pumps air from the hollow portion 1025 of the cylindrical heat exchanger 102, so that a pressure difference is formed between the inner and outer sides of the cylindrical heat exchanger 102 for ventilation and heat dissipation.

[0040] The base 53 is disposed at the bottom of the cylindrical heat exchanger 102 , and the heat exchange fins 101 , the cylindrical heat exchanger 102 and the compressor 20 are supported and installed by the base 53 .

[0041] Thus, the present application bends the condenser tube group 1021 of the heat exchange assembly 10 into a cylindrical cylindrical heat exchanger 102, and the cylindrical heat exchanger 102 also has a hollow portion 1025, and the heat exchange fins 101 are arranged around the cylindrical heat exchanger 102, and the condenser tube group 1021 is inserted through each heat exchange fin 101. Therefore, when performing heat exchange work, the surrounding of the cylindrical heat exchanger 102 can form an annular windward portion 1027, which maximizes the windward area of ​​the cylindrical heat exchanger 102 and reduces the resistance of the fins. Compared with the previous implementation means of the heat exchange assembly 10 with a rectangular setting and only one or two sides for air intake, the air intake volume of the heat exchange assembly 10 of the present application can be increased by about 10%, and under the condition of the same number of condenser tubes and fins, the windward area is expanded by about 30%, which effectively improves the heat exchange efficiency and cooling effect.

[0042] The compressor 20 is arranged in the hollow part 1025 of the cylindrical heat exchanger 102, so that the condenser tube group 1021 surrounds the compressor 20, and the upper end of the compressor 20 is provided with an air inlet pipe 201, and one side of the compressor 20 is provided with an air outlet pipe 202. The condenser tube group 1021 is composed of at least two condenser pipes 1022 connected end to end and bent in parallel. The condenser tube group 1021 at the upper end of the cylindrical heat exchanger 102 forms an air inlet junction 1023 by connecting the two condenser pipes, and the condenser tube group 1021 at the lower end of the cylindrical heat exchanger 102 forms a liquid outlet junction 1024 by connecting the two condenser pipes. Therefore, the air inlet junction 1023 of the condenser tube group 1021 is connected to the air outlet pipe 202 of the compressor 20, so that the evaporated gas of the refrigerant is compressed by the compressor 20 into a high-temperature and high-pressure gas for heat exchange and then transported to the condensing pipe 1022 of the condenser tube group 1021 for heat exchange, and combined with the radiator 30 to drive the surrounding air flow effect for rapid heat dissipation.

[0043] In this way, the present application sets the compressor 20 in the hollow portion 1025 of the cylindrical heat exchanger 102, so as to make full use of the hollow portion 1025 of the cylindrical heat exchanger 102. Compared with the previous implementation method in which the heat exchange component 10 and the compressor 20 are independently set, it saves more installation space, the overall machine is more compact, and it is convenient to connect the compressor 20 with the condenser group 1021, and improve the installation efficiency.

[0044] The cylindrical heat exchanger 102 is placed with the hollow portion 1025 facing vertically upward. Therefore, an exhaust port 1026 is formed at the top of the cylindrical heat exchanger 102. The cooling fan 301 is set above the hollow portion 1025 of the cylindrical heat exchanger 102. The cooling fan 301 is used to pump air in the hollow portion 1025 of the cylindrical heat exchanger 102 so that the pumped air can be discharged outward through the exhaust port 1026. At the same time, external air enters the hollow portion 1025 through the annular windward portion 1027 of the cylindrical heat exchanger 102, thereby realizing air flow on both sides of the cylindrical heat exchanger 102, thereby ventilating and cooling the compressor 20 and the condenser tube group 1021.

[0045] A plurality of support vertical plates 50 are disposed in the hollow portion 1025 of the cylindrical heat exchanger 102. The plurality of support vertical plates 50 are equidistantly arranged in a ring along the inner wall of the cylindrical heat exchanger 102. The lower ends of the support vertical plates 50 are fixedly connected to the base 53 by screws, and the upper ends of the support vertical plates 50 are fixedly connected to the bottom of the cover plate 302 of the radiator 30.

[0046] A reinforcing plate 51 is provided between two heat exchange fins 101. Among the numerous heat exchange fins 101, a reinforcing plate 51 can be selected to be provided between two heat exchange fins 101 separated by a certain circumferential distance. The lower end of the reinforcing plate 51 is fixedly connected to the base 53, and the upper end of the reinforcing plate 51 is fixedly connected to the bottom of the cover plate 302 of the radiator 30. The condenser tube group 1021 of the cylindrical heat exchanger 102 is also connected through the reinforcing plate 51. Therefore, by providing the support vertical plate 50 and the fixed connection between the reinforcing plate 51 and the cover plate 302, the cooling fan 301 can be stably supported and installed, and by providing a plurality of reinforcing plates 51 between the heat exchange fins 101, the assembly stability of the condenser tube group 1021, the heat exchange fins 101 and the radiator 30 on the base 53 can be improved, thereby improving the structural strength of the whole machine.

[0047] In this way, the present application sets the radiator 30 above the hollow portion 1025 of the cylindrical heat exchanger 102, which can not only further reduce the lateral installation space, but also enable the cooling fan 301 to synchronously ventilate and dissipate heat to the condenser tube group 1021 and the compressor 20 through the exhaust port 1026 at the top of the cylindrical heat exchanger 102, thereby avoiding excessive heat and damage to the compressor 20 and increasing its service life; and by matching the cylindrical heat exchanger 102 with a larger frontal area and smaller fin resistance, a cooling fan 301 with a smaller working power can be selected, saving energy consumption and manufacturing costs.

[0048] The cylindrical heat exchanger 102 is connected to a filter 40, one end of which is connected to a liquid inlet pipe 401, and the other end of the filter 40 is connected to a liquid outlet pipe 402. The liquid inlet pipe 401 of the filter 40 is connected to the liquid outlet junction 1024 of the condenser tube group 1021, so that the high-temperature and high-pressure gas of the cylindrical heat exchanger 102 is cooled into liquid through heat dissipation, and the cooling liquid flows to the liquid outlet junction 1024 at the lower end of the cylindrical heat exchanger 102 under the action of gravity. The cooling liquid passes through the liquid outlet junction 1024 and the liquid inlet pipe 401 into the filter 40 for filtering treatment, and the filtered cooling liquid is transported to the evaporator through the liquid outlet pipe 402 for recycling.

[0049] In order to facilitate the arrangement of the air intake pipe 201 of the compressor 20 and the liquid outlet pipe 402 of the filter 40, a pipe layout gap 1028 is set on one side of the cylindrical heat exchanger 102. The pipe layout gap 1028 is formed by the end bends of the condenser pipe group 1021 being arranged at a distance, that is, when the condenser pipe group 1021 is bent in the circumferential direction of the cylinder and rotated in the vertical direction, a certain gap distance is reserved for the end bends of the condenser pipe group 1021 bent in the circumferential direction of the cylinder. In addition, a vertical sealing plate 52 is sealed on the outside of the pipe layout gap 1028, and a hole is opened on the vertical sealing plate 52. The air intake pipe 201 of the compressor 20 and the liquid outlet pipe 402 of the filter 40 are extended outwardly in the direction of the pipe layout gap 1028 and the vertical sealing plate 52 is penetrated through the hole, so that the air intake pipe 201 of the compressor 20 and the liquid outlet pipe 402 of the filter 40 extending outward are stably installed.

[0050] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
