Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to a refrigeration machine with good heat dissipation. Background Technology

[0002] A refrigeration machine is a device that transfers heat from a low-temperature object to a high-temperature environment through mechanical or thermodynamic cycles, thereby achieving cooling or maintaining a low temperature. Its core principle is based on the second law of thermodynamics, and common types include compression, absorption, and semiconductor refrigeration. Compression refrigeration machines use a compressor to drive the refrigerant (such as Freon) through a cycle of compression, condensation, expansion, and evaporation to complete heat absorption and release. Absorption refrigeration machines utilize thermal energy (such as natural gas or waste heat) to drive a chemical reaction between the refrigerant and the absorbent to achieve cooling. Refrigeration machines are widely used in household refrigerators, commercial freezers, industrial refrigeration, air conditioning systems, and low-temperature research environments (such as superconducting experiments), featuring high efficiency, energy saving, and precise temperature control. With increasing environmental protection demands, new refrigeration technologies are gradually adopting low GWP (Global Warming Potential) refrigerants and natural working fluids (such as CO2 and ammonia) to reduce the impact on the ozone layer and climate. Modern refrigeration machines also integrate intelligent control technology to optimize the coefficient of performance (COP), promoting the development of green refrigeration.

[0003] Refrigeration machines are crucial in modern society, widely used in food preservation, medical refrigeration, industrial refrigeration, air conditioning systems, and low-temperature scientific research to ensure the quality of production and daily life. During the daily use of refrigeration machines, the flow rate or volume of the cooling medium to be cooled may be too fast, making it difficult for the refrigeration machine to dissipate heat and cool these cooling media in a timely manner, thus affecting the cooling efficiency of the refrigeration machine. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a refrigeration unit with good heat dissipation.

[0005] This utility model is achieved by the following technical solution: a refrigerator with good heat dissipation, including a cooling mechanism, a heat dissipation mechanism and a main body mechanism, wherein the cooling mechanism is located inside the main body mechanism and the heat dissipation mechanism is located at the top of the main body mechanism;

[0006] The cooling mechanism includes a water inlet, a diverter tube frame is fixedly connected to the end of the water inlet, a finned tube is fixedly connected to the back of the diverter tube frame, a rectifier tube frame is fixedly connected to the end of the finned tube, and a water outlet is fixedly connected to the top of the rectifier tube frame.

[0007] Through the above technical solution, the inlet is fixedly connected to the diversion pipe rack, and the diversion pipe rack is fixedly connected to the finned tubes. When the inlet sends the cooling medium to be cooled into the equipment, the diversion pipe rack can divert the cooling medium and guide it into the finned tubes. By diverting the cooling medium in advance, the flow rate in each finned tube is reduced, thereby avoiding the phenomenon of incomplete cooling of the cooling medium due to excessive flow. The finned tubes are fixedly connected to the rectifier pipe rack, and the rectifier pipe rack is fixedly connected to the outlet. After the cooling medium is cooled by the finned tubes, the rectifier pipe rack can rectify the cooling medium in each finned tube and guide it to flow out through the inside of the outlet. By setting the finned tubes to cool the cooling medium, the heat dissipation efficiency is improved by increasing the heat dissipation area, thereby further increasing the cooling efficiency of the equipment.

[0008] As a further improvement to the above solution, a cooling tank is fixedly connected to the outer wall of the shunt pipe rack, heat dissipation fins are fixedly connected to the outer wall of the cooling tank, and a fixing bracket is fixedly connected to the outer wall of the cooling tank.

[0009] Through the above technical solution, the shunt pipe rack is fixedly connected to the cooling tank, and the cooling tank is fixedly connected to the heat dissipation fins. By setting multiple heat dissipation fins on the outer wall of the cooling tank, the overall heat dissipation volume of the cooling tank can be increased, thereby increasing the heat dissipation effect of the equipment. A fixed support is set to fix the cooling tank to the main body of the refrigeration unit, thereby fixing the cooling tank inside the main body of the refrigeration unit and increasing the stability of the overall structure of the equipment.

[0010] As a further improvement to the above solution, a condensate inlet is fixedly connected to the side wall of the cooling tank, and a condensate outlet is fixedly connected to the side wall of the cooling tank.

[0011] Through the above technical solution, the outer wall of the cooling tank is fixedly connected with a condensate inlet and a condensate outlet. Through the cooperation between the condensate inlet and the condensate outlet, the condensate inside the cooling tank can be circulated, preventing the condensate temperature from rising due to prolonged working time, which would affect the subsequent cooling effect.

[0012] As a further improvement to the above solution, the heat dissipation mechanism includes a protective net, the bottom of which is fixedly connected to the main body of the refrigeration unit, and the top of which is fixedly connected to a mounting bracket.

[0013] Through the above technical solution, the protective net is fixedly connected to the main body of the refrigeration unit. By setting the protective net on the top of the main body of the refrigeration unit, the motor and fan blades can be protected by the protective net, preventing foreign objects from falling in or personnel from accidentally touching them during operation, thereby increasing the safety of the overall equipment.

[0014] As a further improvement to the above solution, a motor is fixedly connected to the bottom of the mounting bracket, and a fan blade is fixedly connected to the output end of the motor.

[0015] Through the above technical solution, the mounting bracket is fixedly connected to the motor and the main body of the refrigeration unit. The motor can be fixed to the top of the refrigeration unit through the mounting bracket. The output end of the motor is fixedly connected to the fan blade. When the motor is driven by an external 220V AC power source, the motor can drive the fan blade to rotate. Through its cooperation with the heat dissipation fins on the surface of the cooling tank, the cooling tank is cooled by air, thereby further increasing the cooling effect of the equipment.

[0016] As a further improvement to the above solution, the main structure includes a refrigeration unit body, a sealing door panel is hinged to the inner wall of the refrigeration unit body, and a foot brake pulley is fixedly connected to the bottom of the refrigeration unit body.

[0017] Through the above technical solution, the main body of the refrigeration unit is hinged to a sealing door panel. By setting a sealing door panel on the outer wall of the main body of the refrigeration unit, the convenience of maintenance and inspection of internal parts can be increased through the sealing door panel. The main body of the refrigeration unit is fixedly connected to foot brake pulleys. By setting multiple foot brake pulleys at the bottom of the main body of the refrigeration unit, the flexibility of the equipment during movement can be increased through the foot brake pulleys.

[0018] As a further improvement to the above solution, ventilation openings are provided on the side wall of the main body of the refrigeration unit.

[0019] Through the above technical solution, ventilation openings are provided on the side wall of the refrigeration unit, which increases the airflow inside the refrigeration unit, thereby increasing the overall heat dissipation efficiency of the equipment. Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention features a fixed inlet and distribution pipe rack. When the cooling medium is introduced into the equipment, the distribution pipe rack diverts the medium and guides it into the finned tubes. By pre-diverting the cooling medium, the flow rate in each finned tube is reduced, preventing incomplete cooling due to excessive flow. A rectifier pipe rack is fixedly connected to the finned tubes, which in turn is fixedly connected to the outlet. After the cooling medium passes through the finned tubes, the rectifier pipe rack rectifies the medium and guides it out through the outlet. The finned tubes increase the heat dissipation area, improving heat dissipation efficiency and further enhancing the equipment's cooling capacity. Multiple heat dissipation fins on the outer wall of the cooling tank increase the overall heat dissipation volume, further improving the cooling effect. The coordinated operation of the refrigerant inlet and outlet ensures refrigerant circulation, preventing excessive refrigerant temperature from affecting the cooling effect.

[0021] This invention features a fan blade fixedly connected to the output end of a motor. When the motor is driven by an external 220V AC power source, it rotates the fan blade, which, in conjunction with the heat dissipation fins on the surface of the cooling tank, provides air cooling, thereby increasing the cooling effect of the equipment. A motor mounting bracket is provided, which is fixedly connected to the main body of the refrigeration unit. The motor can be fixed to the top of the refrigeration unit by the mounting bracket. A protective net is installed on the top of the refrigeration unit to protect the motor and fan blade, preventing foreign objects from falling in or personnel from accidentally touching them during operation, thus increasing the overall safety of the equipment.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figures 1-5 A refrigerator with good heat dissipation according to this embodiment includes a cooling mechanism 1, a heat dissipation mechanism 2 and a main body mechanism 3. The cooling mechanism 1 is located inside the main body mechanism 3 and the heat dissipation mechanism 2 is located on top of the main body mechanism 3.

[0032] The cooling mechanism 1 includes a water inlet 101, a diversion tube frame 102 fixedly connected to the end of the water inlet 101, a finned tube 103 fixedly connected to the back of the diversion tube frame 102, a rectifier tube frame 104 fixedly connected to the end of the finned tube 103, and a water outlet 105 fixedly connected to the top of the rectifier tube frame 104.

[0033] A cooling tank 106 is fixedly connected to the outer wall of the distribution pipe rack 102, and heat dissipation fins 107 are fixedly connected to the outer wall of the cooling tank 106. A fixing bracket 108 is fixedly connected to the outer wall of the cooling tank 106.

[0034] A condensate inlet 109 is fixedly connected to the side wall of the cooling tank 106, and a condensate outlet 110 is fixedly connected to the side wall of the cooling tank 106.

[0035] The heat dissipation mechanism 2 includes a protective net 201, the bottom of which is fixedly connected to the main body of the refrigeration unit 301, and the top of which is fixedly connected to the mounting bracket 202.

[0036] A motor 203 is fixedly connected to the bottom of the mounting bracket 202, and a fan blade 204 is fixedly connected to the output end of the motor 203.

[0037] The main body 3 includes a refrigeration unit body 301, a sealing door panel 302 is hinged to the inner wall of the refrigeration unit body 301, and a foot brake pulley 303 is fixedly connected to the bottom of the refrigeration unit body 301.

[0038] Ventilation openings 304 are provided on the side wall of the main body 301 of the refrigeration unit.

[0039] The implementation principle of a refrigeration unit with good heat dissipation in this application embodiment is as follows: A diversion pipe frame 102 is fixedly connected to an inlet 101. When the cooling medium to be cooled is sent into the equipment through the inlet 101, the diversion pipe frame 102 can divert the cooling medium and guide it into the finned tubes 103. By pre-diverting the cooling medium, the flow rate in each finned tube 103 is reduced, thereby avoiding incomplete cooling due to excessive flow. A rectifier pipe frame 104 is fixedly connected to the finned tubes 103. The rectifier tube frame 104 is fixedly connected to the outlet 105. After the cooling medium is cooled by the finned tubes 103, the rectifier tube frame 104 can rectify the cooling medium in each finned tube 103 and guide it to flow out through the inside of the outlet 105. By setting the finned tubes 103 to cool the cooling medium, the heat dissipation efficiency can be improved by increasing the heat dissipation area of ​​the finned tubes 103, thereby further increasing the cooling efficiency of the equipment. By setting multiple heat dissipation fins 107 on the outer wall of the cooling tank 106, the heat dissipation fins can be used to further improve the cooling efficiency of the equipment. 107 increases the overall heat dissipation volume of the cooling tank 106, thereby increasing the heat dissipation effect of the equipment. The interaction between the condensate inlet 109 and the condensate outlet 110 ensures condensate circulation, preventing excessively high condensate temperatures from affecting the cooling effect. A fan blade 204 is fixedly connected to the output end of the motor 203. When the motor 203 is driven by an external 220V AC power source, it rotates the fan blade 204. This fan blade, in conjunction with the heat dissipation fins 107 on the surface of the cooling tank 106, effectively cools the cooling tank 106. 6. Air cooling is used to further increase the cooling effect of the equipment. The motor 203 is fixedly connected to the mounting bracket 202, which is fixedly connected to the main body of the refrigeration unit 301. The motor 203 can be fixed to the top of the main body of the refrigeration unit 301 through the mounting bracket 202. By setting a protective net 201 on the top of the main body of the refrigeration unit 302, the motor 203 and the fan blades 204 can be protected to prevent foreign objects from falling in or personnel from accidentally touching them during operation, thereby increasing the overall safety of the equipment.

[0040] It should be noted that motor 203 can be a three-phase asynchronous motor of the Nanjing Mingtai brand, model "YE3-110L1-4", which is a common type of motor drive in mechanical structures.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
