Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration devices, and particularly to an energy-saving circulating refrigeration unit capable of quickly discharging heat. Background Art

[0002] Refrigeration units are core devices used to achieve temperature control in industrial, commercial, and civil fields. Heat transfer is realized through the refrigerant cycle, and their technical characteristics, application scenarios, and energy efficiency performance directly affect the use effect.

[0003] The core of the energy-saving circulating refrigeration unit is based on the vapor compression refrigeration cycle. Heat transfer is achieved through the phase change process of the refrigerant among the compressor, condenser, expansion valve, and evaporator. Specifically: the compressor compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gas, consuming electrical energy. The high-temperature and high-pressure gas releases heat to the external environment (air or water) in the condenser and condenses into a high-pressure liquid. The high-pressure liquid passes through the expansion valve for throttling and pressure reduction and becomes a low-temperature and low-pressure wet steam. The low-temperature and low-pressure wet steam absorbs the heat of the medium to be cooled in the evaporator and evaporates into a gas, completing the refrigeration cycle.

[0004] When existing refrigeration units are in use, most of them are cooled through a water-cooling cycle, and generally, a fan is also provided to dissipate heat by accelerating the air circulation. However, the flowing time of the condensed liquid after heat absorption in the water storage tank is short, which cannot ensure that the condensed liquid after heat absorption can well export the absorbed heat, resulting in residual heat in the condensed liquid re-entering the condenser body, and thus the heat in the condenser cannot be fully circulated and absorbed, reducing the refrigeration efficiency.

[0005] Therefore, it is necessary to provide an energy-saving circulating refrigeration unit capable of quickly discharging heat to solve the above problems. Summary of the Invention

[0038] In this embodiment, through the setting of the protective shell 1, effective safety protection can be provided for the refrigeration unit, avoiding damage to the refrigeration unit caused by external impacts or scratches. Through the setting of the heat dissipation component 6, the flow time of the heat-absorbed condensate in the water storage tank 5 can be greatly extended, which helps to fully absorb and treat the condensate, facilitating the enhancement of the refrigeration effect of the refrigeration unit. At the same time, the heat dissipation component 6 conducts the absorbed heat out of the water storage tank 5. Through the cooperation of the air-cooling component 4, the air intake net opening 103 and the heat dissipation grid 104, rapid and efficient air-cooling treatment of the heat can be carried out. Through the cooperation of the cleaning component 7 and the collection component 8, the surface of the heat dissipation component 6 can be reciprocally cleaned, avoiding dust introduced during the air-cooling process from adhering to the surface of the heat dissipation component 6 and affecting the heat dissipation effect of the heat dissipation component 6, helping to maintain the heat dissipation efficiency, facilitating rapid heat dissipation, and at the same time, the cleaned dust can be centrally processed, avoiding dust adhering to the inner wall of the protective shell 1 and affecting heat dissipation and cleanliness.

[0041] In this embodiment, the heat-absorbed condensate flows back into the water storage tank 5 through the return pipe 503. The flowing-back condensate flows along the surface of the left first heat conducting plate 601 towards the two side walls of the water storage tank 5, and then the condensate on both sides flows along the surfaces of the corresponding second heat conducting plates 603 towards the middle of the water storage tank 5. Then, the flowing condensate continues to flow towards the direction close to the first slots 602 after passing through the spacing between the symmetrically arranged third heat conducting plates 604; the flowing-back condensate will flow in a multiple S-shaped manner in sequence. Finally, the water inlet pipe 502 pumps out the condensate on the right side of the water storage tank 5 and introduces it into the condenser body 302 through the return pipe 503, realizing the refrigeration treatment of the refrigeration unit;

[0042] By providing a plurality of first heat conducting plates 601 and second heat conducting plates 603, the flowing time of the condensate inside the water storage tank 5 can be greatly extended, facilitating the absorption and conduction of heat in the condensate by the first heat conducting plates 601 and the second heat conducting plates 603 to the outside. Through the provision of the first slots 602 and the second slots 605, the contact area between the first heat conducting plates 601 and the third heat conducting plates 604 and the air inside the protective housing 1 can be enlarged, facilitating rapid heat dissipation treatment.

[0043] In an embodiment of the present invention, referring to Figures 1 - 5, the cleaning component 7 includes a mounting plate 701 installed on the inner wall of the protective shell 1 near the heat dissipation grid 104. A reciprocating lead screw 703 is rotatably connected between the mounting plate 701 and the bottom of the protective shell 1. The reciprocating lead screw 703 is connected to a rotating motor 702 installed on the mounting plate 701. A lifting plate 704 is movably arranged inside the protective shell 1. The lifting plate 704 is slidably matched with the reciprocating lead screw 703. A guide rod 708 that is slidably matched with the lifting plate 704 is connected between the mounting plate 701 and the bottom of the protective shell 1.

A plurality of first cleaning brushes 707 that are movably in contact with the outer wall of the third heat conducting plate 604 are installed at one end of the connecting plate 705 away from the heat dissipation grid 104. A vertical rod 706 that is slidably matched with the connecting plate 705 is connected between the mounting frame 304 and the bottom of the protective shell 1.

[0045] In this embodiment, the rotating motor 702 drives the reciprocating lead screw 703 to rotate. The reciprocating lead screw 703 drives the lifting plate 704 to reciprocate up and down by means of being slidably matched with the lifting plate 704 and the lifting plate 704 being slidably matched with the guide rod 708. The lifting plate 704 drives the connecting plate 705 to synchronously move up and down by being connected to the connecting plate 705 and the connecting plate 705 being slidably matched with the vertical rod 706. The connecting plate 705 drives a plurality of first cleaning brushes 707 and the second cleaning brush 709 to synchronously move up and down;

[0046] The first cleaning brush 707 sweeps the dust adhering to the surface of the third heat conducting plate 604 by reciprocating up and down, which can effectively maintain the heat conduction performance of the third heat conducting plate 604, avoid excessive dust accumulation resulting in the inability of the third heat conducting plate 604 to transfer heat with the air inside the protective shell 1, and improve the heat dissipation performance;

[0047] The second cleaning brush 709 cleans the dust adhering to the inside of the heat dissipation grid 104 by reciprocating up and down, preventing dust accumulation from blocking the ventilation channel of the heat dissipation grid 104, facilitating the circulation of air between the inside and outside of the protective shell 1, and facilitating rapid heat dissipation;

[0048] The dust adhering to the surface of the third heat conduction plate 604 will fall into the first collection box 802 through the first through groove 801 after being cleaned, and the dust adhering to the inner wall of the heat dissipation grid 104 will fall into the second collection box 804 through the second through groove 803 after being cleaned, which can achieve centralized collection of dust. Through the sliding fit between the first collection box 802 and the protective shell 1 and the sliding fit between the second collection box 804 and the protective shell 1, the first collection box 802 and the second collection box 804 can be pulled out and the dust collected inside the first collection box 802 and the second collection box 804 can be centrally processed, facilitating the orderly processing of dust.

[0049] Among them, the first cleaning brush 707 is set as a U-shaped brush, which can clean the two side surfaces of the third heat conduction plate 604.
