Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, specifically to a liquid-cooled industrial refrigeration machine. Background Technology

[0002] Industrial refrigeration units are specialized refrigeration equipment used in industrial production scenarios to precisely control temperature and maintain stable process flows. Their core function is to transfer or dissipate heat generated during production through artificial refrigeration technology, ensuring that materials, equipment, or the environment remain within a specific low-temperature range. Their working principle is based on a refrigeration cycle, typically using refrigerants such as ammonia, Freon, or ethylene glycol. Through core components such as compressors, condensers, evaporators, and expansion valves, they achieve the compression, condensation, throttling, and evaporation of the refrigerant, thereby absorbing heat and lowering the temperature of the target area.

[0003] Current liquid-cooled industrial chillers have significant limitations in application. Their cooling coverage area is generally small, making it difficult to meet the cooling needs of large production equipment or large-area process scenarios. More importantly, the cooling area of ​​existing equipment is mostly fixed in design, lacking flexible adjustment capabilities. In actual industrial production, localized cooling needs are very common, such as only needing to control the temperature of materials in the upper part of a device to prevent volatilization, or only needing to dissipate heat to ensure the safety of core components in the lower part of the device. However, due to the limitations of the fixed design, the equipment must be activated across the entire area to meet the localized needs. This not only results in energy waste in areas that do not need cooling, increasing enterprise operating costs, but may also affect process stability due to excessive cooling of non-target areas. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a liquid-cooled industrial refrigeration machine that allows for adjustment of the refrigeration zone and avoids energy waste.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a liquid-cooled industrial refrigeration machine, comprising:

[0006] The frame has a perforated mounting plate symmetrically fixed to its bottom surface.

[0007] Cooling pipes are fixedly installed inside the frame, and several are installed at equal intervals.

[0008] The liquid inlet pipe rack includes a main liquid inlet pipe and branch liquid inlet pipes. The main liquid inlet pipe is located on one side of the frame. The branch liquid inlet pipes are fixedly installed on the main liquid inlet pipe and are connected to the cooling pipes one by one. Control valves are fixedly installed on them.

[0009] The liquid outlet pipe rack includes a main liquid outlet pipe and branch liquid outlet pipes. The main liquid outlet pipe is located on the other side of the frame, and the branch liquid outlet pipes are fixedly installed on the main liquid outlet pipe and are connected to the cooling pipes one by one.

[0010] The cooling plate is detachably mounted on the front side of the frame, with the cooling pipes attached to its rear wall.

[0011] Furthermore, the perforated mounting plate extends to the front and rear sides of the frame, and there are no fewer than four mounting holes on the same perforated mounting plate.

[0012] Furthermore, the cooling pipe is a square pipe.

[0013] Furthermore, the end of the main inlet pipe is provided with an inlet.

[0014] Furthermore, an outlet pipe is provided at the end of the main outlet pipe.

[0015] Furthermore, the cooling plate is an aluminum alloy plate, and connecting plates are fixed at its four corners. The connecting plates are connected and fixed to the frame by screws.

[0016] Compared with existing technologies, the advantages of this invention are as follows: the control valve on the inlet branch pipe can independently regulate the coolant supply to the corresponding cooling pipe. When only local cooling is needed, the control valve of the area not requiring cooling can be closed, reducing coolant circulation consumption in unnecessary areas. Simultaneously, the cooling plate adopts a detachable design, allowing for selective installation and removal based on actual cooling needs, suitable for both environmental and object-specific heat dissipation. The cooling pipes are tightly fitted to the rear wall of the cooling plate, ensuring cooling efficiency. This allows for precise adjustment of the cooling area to meet specific requirements without excessive energy consumption due to ineffective cooling, thus avoiding energy waste.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 Appendix Figure 3A liquid-cooled industrial refrigeration unit includes: a frame 1, with a perforated mounting plate 2 symmetrically fixed on the bottom surface. The perforated mounting plate 2 extends to the front and rear sides of the frame 1, and there are no fewer than four mounting holes on the same perforated mounting plate 2. This can greatly improve the stability of the refrigeration unit during installation, and at the same time provide more fixed point options for different installation scenarios, making it more adaptable.

[0024] Combined with appendix Figure 4 Cooling pipes 3 are fixedly installed inside the frame 1, and several are evenly spaced. The cooling pipes 3 are square pipes, which can increase the contact area with the back wall of the cooling plate 9 compared with round pipes, making heat transfer more efficient and accelerating the cooling speed. At the same time, the square structure is also convenient to be neatly arranged inside the frame 1, improving the space utilization rate.

[0025] Combined with appendix Figure 1 Appendix Figure 2 The inlet pipe rack includes a main inlet pipe 4 and inlet branch pipes 5. The main inlet pipe 4 is located on one side of the frame 1. The inlet branch pipes 5 are fixedly installed on the main inlet pipe 4 and are connected to the cooling pipes 3 one by one. A control valve 6 is fixedly installed on each branch pipe. The end of the main inlet pipe 4 is provided with an inlet port 10, which makes it easier to connect when the coolant is input, avoids connection misalignment or leakage, simplifies the coolant replenishment process, and reduces the difficulty of daily maintenance operations.

[0026] Combined with appendix Figure 2 Appendix Figure 4 The liquid outlet pipe rack includes a main liquid outlet pipe 7 and branch liquid outlet pipes 8. The main liquid outlet pipe 7 is located on the other side of the frame 1. The branch liquid outlet pipes 8 are fixedly installed on the main liquid outlet pipe 7 and are connected to the cooling pipes 3 one by one. The end of the main liquid outlet pipe 7 is provided with a liquid outlet pipe 11, which can smoothly discharge the coolant after absorbing heat, avoid accumulating in the main pipe and affecting the circulation efficiency, ensure the continuity of coolant circulation in the refrigeration system, and maintain a stable cooling effect.

[0027] Combined with appendix Figure 1 Appendix Figure 2 The cooling plate 9 is detachably mounted on the front side of the frame 1, with the cooling pipe 3 attached to its rear wall. The cooling plate 9 is made of aluminum alloy, which has good thermal conductivity and can improve heat exchange efficiency. Connecting plates 12 are fixed at its four corners. The connecting plates 12 are connected and fixed to the frame 1 by screws, which facilitates the disassembly, use and replacement of the cooling plate 9 in the future and reduces maintenance costs.

[0028] The specific implementation method of this utility model is as follows: First, using the perforated mounting plate 2 on the bottom surface of the frame 1, with at least four mounting holes, the refrigeration unit is securely installed in the required position to adapt to different installation scenarios. Next, coolant is continuously injected from the inlet 10 at the end of the main inlet pipe 4. The coolant is distributed to each inlet branch pipe 5 through the main inlet pipe 4. The coolant supply to the corresponding cooling pipe 3 can be independently adjusted according to the cooling demand through the control valve 6 on the inlet branch pipe 5. If only local cooling is required, the control valve 6 of the area that does not need cooling can be closed.

[0029] After the coolant enters the cooling pipe 3, it transfers heat through the pipe to achieve cooling. For ambient cooling, the cooling pipe 3 can be directly exposed to the environment for heat exchange. For cooling an object, a cooling plate 9 can be installed on the front side of the frame 1, with the object to be cooled in contact with the front wall of the cooling plate 9. Because the cooling pipe 3 is a square tube, it can fully fit against the rear wall of the cooling plate 9, increasing the contact area and efficiently transferring heat. The aluminum alloy cooling plate 9 further enhances the heat exchange efficiency. The coolant, after absorbing heat, flows through the outlet branch pipes 8, which are connected one-to-one with the cooling pipe 3, into the outlet main pipe 7, and is finally discharged from the outlet main pipe 7, ensuring continuous coolant circulation. The entire process precisely meets cooling needs while avoiding energy waste.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
