[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] like Figures 1 to 3 As shown, one embodiment of this utility model provides a refrigeration device, which includes a compressor body 1, a heat exchanger 2, and a heat exchange component 3. The compressor body 1 has a refrigerant inlet 11 for introducing refrigerant and a refrigerant outlet 12 for discharging refrigerant. The heat exchanger 2 includes a refrigerant flow path 21 and a cooling medium flow path 22 for heat exchange with the refrigerant flow path 21, and the outlet of the refrigerant flow path 21 is connected to the refrigerant inlet 11. The heat exchange component 3 is disposed on the outer wall of the compressor body 1, and the heat exchange component 3 has a heat exchange cavity 31 for heat exchange with the outer wall of the compressor body 1, and the outlet of the cooling medium flow path 22 is connected to the heat exchange cavity 31.

[0046] The refrigeration equipment provided in one embodiment of this utility model prepares a low-temperature cooling medium through the refrigerant in the heat exchanger 2. The cooling medium is then introduced into the heat exchange chamber 31 of the heat exchanger 3 via the heat exchange element 3. By exchanging heat between the outer wall of the compressor body 1 and the heat exchange chamber 31, the compressor exhaust temperature can be reduced, thereby avoiding the risk of decreased equipment efficiency or damage due to excessively high temperatures. Using the heat exchanger 2 to prepare the cooling medium avoids the additional energy consumption required for its preparation, reducing energy consumption, lowering operating costs, and improving the integration and overall thermal efficiency of the equipment. Therefore, the refrigeration equipment provided in this embodiment can solve the problem of insufficient heat dissipation of compressors in existing refrigeration equipment.

[0047] Specifically, the cooling medium in the cooling medium flow path 22 is pure water or hydraulic oil. Pure water or hydraulic oil has a high specific heat capacity, which can absorb and store a large amount of heat, helping to maintain the temperature stability of the compressor body 1.

[0048] In one embodiment, the heat exchanger 3 is in the form of a multi-layer coil, which is made of a highly thermally conductive metal and is wound around the outer wall of the compressor body 1. The multi-layer coil design increases the contact area with the outer wall of the compressor body 1, thereby improving the heat exchange efficiency.

[0049] In one embodiment, the heat exchanger 3 adopts a sandwich structure, wherein the heat exchange cavity 31 is formed by two plates spaced apart from each other, serving as a flow channel for the cooling medium. One of the plates is tightly attached to the outer wall of the compressor body 1. This design allows the cooling medium to indirectly contact the outer wall of the compressor body 1 and achieve heat exchange when flowing through the heat exchange cavity 31, thereby enhancing heat transfer.

[0050] In one embodiment, the heat exchanger 3 includes an upper end plate, a wall plate, and a lower end plate connected in sequence. The upper and lower end plates are arranged opposite to each other, forming a heat exchange cavity 31. The ends of the upper and lower end plates away from the wall plate are both connected to the outer wall of the compressor body 1. This arrangement allows the cooling medium flowing in the heat exchange cavity 31 to directly contact the outer wall of the compressor body 1, thereby producing a better heat exchange effect and improving heat exchange efficiency.

[0051] In one embodiment, the heat exchanger 3 is a microchannel plate structure with tiny flow channels distributed on the plate, allowing the cooling medium to circulate rapidly within a very small space. The microchannel plate structure is in close contact with the outer wall of the compressor body 1. The use of the microchannel structure increases the heat exchange area per unit volume, thereby significantly improving the heat exchange efficiency.

[0052] In one embodiment, an ultrasonic generator is provided in the heat exchange chamber 31 of the heat exchanger 3. The ultrasonic generator is used to periodically remove deposits and scale in the chamber, maintain stable heat exchange efficiency, and reduce maintenance requirements.

[0053] Specifically, the heat exchanger 3 has a first end 32 and a second end 33 spaced apart along the height direction of the compressor body 1, with the first end 32 located above the second end 33; wherein the second end 33 is located below the motor 15 of the compressor body 1 or flush with the end of the motor 15 near the pump body 13 of the compressor body 1. With this structural arrangement, the second end 33 is the lower end of the heat exchanger 3, which helps to cover the hottest part of the compressor body 1 (usually near the motor 15), thereby directly and effectively reducing the temperature of the motor 15 area. Since the motor 15 generates a large amount of heat during operation, placing the second end 33 of the heat exchanger 3 in this position allows for effective management of the motor 15 temperature, improving the reliability and operating efficiency of the compressor.

[0054] Specifically, the heat exchanger 3 has a first end 32 and a second end 33 spaced apart along the height direction of the compressor body 1, with the first end 32 located above the second end 33; wherein the second end 33 is located above the upper flange 14 of the compressor body 1 or flush with the end of the pump body 13 away from the compressor body 1 of the upper flange 14. With this structural arrangement, by placing the bottom end face of the heat exchanger 3 above the upper flange 14 or flush with the upper end of the upper flange 14, interference with the pump body 13 can be avoided, ensuring the normal operation of the compressor body 1.

[0055] Specifically, the end of the upper flange 14 away from the pump body 13 of the compressor body 1 is the point closest to the bottom of the compressor body 1 on the side of the upper flange 14 away from the pump body 13.

[0056] Specifically, the heat exchanger 3 has a first end 32 and a second end 33 spaced apart along the height direction of the compressor body 1, with the first end 32 located above the second end 33; wherein the first end 32 is located above the motor 15 of the compressor body 1 or flush with the end of the motor 15 away from the pump body 13 of the compressor body 1. With this structural arrangement, placing the first end 32 of the heat exchanger 3 above the motor 15 or flush with the end of the motor 15 away from the pump body 13 allows for rapid absorption of the heat generated during the operation of the motor 15. This not only helps control the temperature of the motor 15 but also reduces efficiency loss and potential failure risks caused by overheating of the motor 15.

[0057] Specifically, the heat exchanger 3 has a first end 32 and a second end 33 spaced apart along the height direction of the compressor body 1, with the first end 32 located above the second end 33. Specifically, the first end 32 is located above the motor 15 of the compressor body 1 or flush with the end of the motor 15 away from the pump body 13 of the compressor body 1. The second end 33 is located below the motor 15 of the compressor body 1 or flush with the end of the motor 15 near the pump body 13 of the compressor body 1. This structural arrangement, with the second end 33 being the lower end of the heat exchanger 3, facilitates the heat exchanger 3 covering part of the motor 15, thereby directly and effectively reducing the temperature in the motor 15 area. Since the motor 15 generates a large amount of heat during operation, this arrangement enables effective management of the motor 15 temperature, improving the reliability and operating efficiency of the compressor.

[0058] Specifically, the heat exchanger 3 includes an upper end plate, a wall plate, and a lower end plate connected in sequence. The upper and lower end plates are arranged opposite to each other, and the upper end plate, wall plate, and lower end plate form a heat exchange cavity 31. The ends of the upper end plate and the lower end plate that are away from the wall plate are both connected to the outer wall of the compressor body 1. The first end 32 is the side of the upper end plate away from the wall plate, and the second end 33 is the side of the lower end plate away from the wall plate.

[0059] Specifically, for ease of assembly and processing, as well as for versatility, the heat exchanger 3 is coaxially assembled with the compressor body.

[0060] In one embodiment, the heat exchanger 3 is flexibly attached to the outer wall of the compressor body 1. This structural arrangement allows for flexible placement of the heat exchanger 3 based on the heat generation at different locations within the compressor body 1. This enables the most efficient heat absorption and dissipation according to the actual operating conditions and environmental factors of the compressor body 1, thereby better controlling the temperature of the compressor body 1 and ensuring its operation within the optimal temperature range.

[0061] Specifically, the refrigeration equipment also includes a noise detection device, the detection end of which is located on one side of the compressor body 1 and is used to detect the frequency of noise from the compressor body 1. The refrigeration equipment also includes a control device, to which both the heat exchanger 3 and the noise detection device are connected. The control device is used to control the position of the heat exchanger 3 based on the detection results of the noise detection device.

[0062] Specifically, when the peak frequency of the noise detected by the noise detection device is in the range of 0-2000Hz (inclusive), it is generally airflow pulsation noise caused by the compressor pump body 13. The control device is used to adjust the position of the heat exchanger 3 to be closer to the pump body 13. When the peak frequency of the noise detected by the noise detection device is in the range of 2000-5000Hz (exclusive to 2000Hz, inclusive to 5000Hz), it is generally electromagnetic noise caused by the compressor motor 15. The control device is used to adjust the position of the heat exchanger 3 to be closer to the motor 15.

[0063] Specifically, the height, thickness, and placement of the heat exchanger 3, as well as the volume of the heat exchange chamber 31, can be adjusted according to the compressor's noise peak frequency and resonant frequency. Specifically, the placement of the heat exchanger 3 is adjusted based on the peak frequency of the spectrum through compressor noise spectrum analysis or acoustic simulation software.

[0064] In one embodiment, the heat exchanger 3 has an annular structure and is fitted onto the compressor body 1, with the heat exchange chamber 31 surrounding the compressor body 1. This structural arrangement allows the annular heat exchanger 3 to tightly surround the outer wall of the compressor body 1, meaning it can efficiently absorb heat emitted from the compressor body 1 from all directions, achieving comprehensive and uniform heat exchange. This helps reduce the overall temperature of the compressor body 1, improving its operating efficiency and reliability. The annular design also allows the heat exchanger 3 to fit compactly onto the compressor body 1, saving internal space in the refrigeration equipment and facilitating overall layout optimization, especially in space-constrained applications. Furthermore, the annular structure of the heat exchanger 3, fitted onto the compressor body 1, provides additional lateral support and protection, enhancing the structural stability and vibration resistance of the entire device.

[0065] In one embodiment, the heat exchanger 3 further includes a liquid inlet 34 and a liquid outlet 35 for discharging the cooling medium. Both the liquid inlet 34 and the liquid outlet 35 are connected to the heat exchange chamber 31. The liquid inlet 34 is connected to the outlet of the cooling medium flow path 22, and the liquid outlet 35 is located above the liquid inlet 34. This structural arrangement, with the liquid outlet 35 positioned above the liquid inlet 34, helps ensure that the heat exchange chamber 31 is filled with cooling medium, facilitates automatic air venting at the start of cooling medium circulation, avoids air resistance, and ensures smooth flow of the cooling medium.

[0066] Specifically, the inlet 34 and outlet 35 are arranged opposite each other. This structural arrangement, with the inlet 34 and outlet 35 facing each other, helps the cooling medium to form a circulation after entering the heat exchange chamber 31, thereby increasing the path and time of contact between the cooling medium and the outer wall of the compressor body 1. This circulation path helps improve heat exchange efficiency because the cooling medium can more fully absorb the heat dissipated by the compressor body 1. At the same time, the oppositely arranged inlet 34 and outlet 35 also helps to ensure the uniform distribution of the cooling medium inside the heat exchange chamber 31, reducing the temperature gradient and ensuring that all parts of the compressor body 1 receive a consistent cooling effect, which helps to extend the service life of the compressor body 1 and improve operational stability.

[0067] Specifically, there are multiple liquid inlets 34 and multiple liquid outlets 35. The multiple liquid inlets 34 are spaced apart along the outer edge of the heat exchanger 3, and the multiple liquid outlets 35 are spaced apart along the outer edge of the heat exchanger 3. With this structural arrangement, the design of multiple liquid inlets 34 and liquid outlets 35 can further promote the uniform distribution and circulation of the cooling medium in the heat exchange chamber 31. Especially for large or high heat load compressor bodies 1, it can ensure that the heat exchange effect of each area is consistent and avoid local overheating.

[0068] In one embodiment, the heat exchanger 3 extends along the periphery of the compressor body 1; wherein: a guide channel is provided on the inner wall of the heat exchange cavity 31, and the guide channel is spirally arranged around the outer wall of the compressor body 1; there are multiple guide channels, which are spaced apart along the height direction of the compressor body 1. With this structural arrangement, the spiral guide channel design guides the cooling medium to form a spiral upward flow path, increasing the contact area and time between the cooling medium and the outer wall of the compressor body 1, thereby significantly improving the heat exchange efficiency. During the flow process, the cooling medium can more thoroughly absorb the heat emitted by the compressor body 1, achieving a more efficient cooling effect. The multiple spiral guide channels spaced apart along the height direction of the compressor body 1 help promote the uniform distribution of the cooling medium in the heat exchange cavity 31, ensuring a uniform temperature on the surface of the compressor body 1, avoiding the generation of local hot spots, and improving the operational stability and reliability of the refrigeration equipment.

[0069] In one embodiment, the heat exchanger 3 extends along the periphery of the compressor body 1; wherein: multiple guide vanes are provided on the inner wall of the heat exchange cavity 31, and the multiple guide vanes are spaced apart along the height direction of the compressor body 1; each guide vane extends along the periphery of the compressor body 1, and each guide vane is provided with a flow port, with the flow ports of adjacent guide vanes staggered. This structural arrangement, with multiple guide vanes, helps guide the cooling medium to form a more complex and orderly flow pattern within the heat exchange cavity 31. The staggered flow ports prevent direct short-circuit flow of the cooling medium, promoting thorough mixing and circulation of the cooling medium within the cavity, and improving heat exchange efficiency. Simultaneously, the flow port design on the guide vanes also induces turbulence in the cooling medium as it passes through the flow ports. The turbulence effect significantly increases the heat transfer coefficient of the cooling medium, thereby increasing the heat exchange rate and achieving faster temperature regulation.

[0070] In one embodiment, the refrigeration equipment further includes a first connecting flow path 41 and a first valve body 42. The outlet of the cooling medium flow path 22 is connected to the heat exchange chamber 31 through the first connecting flow path 41. The first valve body 42 is disposed on the first connecting flow path 41, and the opening degree of the first valve body 42 is adjustable. With this structural arrangement, the combination of the first connecting flow path 41 and the first valve body 42 can quickly respond to temperature changes in the compressor body 1 and adjust the flow rate of the cooling medium in real time. When the exhaust temperature of the compressor body 1 is low, the flow rate of the cooling medium can be limited by reducing the opening degree of the first valve body 42 to avoid overcooling; conversely, when enhanced cooling is required, the opening degree of the first valve body 42 can be increased to increase the flow rate of the cooling medium, achieve rapid cooling, and ensure that the compressor body 1 is within the ideal operating temperature range.

[0071] Specifically, the first valve body 42 is a proportional solenoid valve, which has opening, closing, and proportional adjustment functions. The first valve body 42 can also be a combination of a common solenoid valve and an electronic expansion valve, wherein the common solenoid valve controls opening and closing, and the electronic expansion valve controls the opening degree.

[0072] In one embodiment, the refrigeration equipment further includes a control component, with the first valve body 42 connected to the control component. The refrigeration equipment also includes a temperature detection component, the detection end of which is located at the refrigerant outlet 12 and used to detect the exhaust temperature at the refrigerant outlet 12. The temperature detection component is connected to the control component, which controls the opening degree of the first valve body 42 based on the detection result of the temperature detection component. With this structural arrangement, the exhaust temperature at the refrigerant outlet 12 is monitored in real time by the temperature detection component, and the data is fed back to the control component, achieving automatic adjustment of the opening degree of the first valve body 42. This automatic adjustment mechanism can precisely control the flow rate of the cooling medium according to the actual operating temperature of the compressor body 1, ensuring that the temperature of the compressor body 1 is maintained within a safe and ideal range, avoiding equipment damage caused by excessively high or low temperatures.

[0073] In one embodiment, the refrigeration equipment further includes a control component, with the first valve body 42 connected to the control component. The refrigeration equipment also includes a liquid level detection component, the detection end of which is disposed within the heat exchange chamber 31 and used to detect the liquid level of the cooling medium within the heat exchange chamber 31. The liquid level detection component is connected to the control component, which controls the opening degree of the first valve body 42 based on the detection result of the liquid level detection component. With this structural arrangement, the introduction of the liquid level detection component enables the system to monitor the cooling medium level within the heat exchange chamber 31 in real time. When the liquid level is lower than a set value, the control component automatically adjusts the opening degree of the first valve body 42, increasing the flow rate of the cooling medium to ensure sufficient cooling medium within the heat exchange chamber 31 and maintain the normal operation of the system.

[0074] Specifically, the control unit has a receiving unit and a control unit connected to each other; wherein: when the refrigeration equipment includes a temperature detection unit, the receiving unit is used to receive the detection signal from the temperature detection unit, and the control unit is used to open the first valve body 42 when the temperature detection unit detects that the exhaust temperature is greater than or equal to a preset exhaust temperature; and to close the first valve body 42 when the temperature detection unit detects that the exhaust temperature is less than the preset exhaust temperature; wherein the preset exhaust temperature is greater than or equal to 85°C and less than or equal to 105°C. With this structural arrangement, real-time monitoring of the exhaust temperature by the temperature detection unit, combined with dynamic adjustment of the opening degree of the first valve body 42 by the control unit, reduces unnecessary cooling medium circulation, lowers energy consumption, and achieves energy efficiency optimization of the refrigeration equipment.

[0075] It should be noted that the preset exhaust temperature needs to be determined according to the actual use of the system. The preset exhaust temperature will vary depending on the type of compressor, the type of refrigerant, etc.

[0076] In one embodiment, the preset exhaust temperature is 90°C.

[0077] Specifically, the control unit has a receiving unit and a control unit connected to each other; wherein: when the refrigeration equipment includes a liquid level detection unit, the receiving unit is used to receive the detection signal from the liquid level detection unit, and the control unit is used to increase the opening of the first valve body 42 when the liquid level detection unit detects that the liquid level in the heat exchange chamber 31 is less than a preset liquid level; and to keep the opening of the first valve body 42 unchanged when the liquid level detection unit detects that the liquid level in the heat exchange chamber 31 is greater than or equal to the preset liquid level; wherein the ratio of the preset liquid level to the height of the heat exchange chamber 31 along the height direction of the compressor body 1 is greater than or equal to 3 / 4 and less than or equal to 1. With this structural arrangement, the cooperative use of the liquid level detection unit and the control unit enables the system to accurately manage the cooling medium liquid level in the heat exchange chamber 31, ensuring sufficient liquid level and avoiding equipment performance degradation or overheating due to excessively low liquid level.

[0078] Specifically, such as Figure 3As shown, the heating equipment also includes a condenser 81, a fan blade 82, a drive motor 83, and an expansion valve 84. The refrigerant outlet 12 of the compressor body 1 is connected to the condenser 81, the condenser 81 is connected to the expansion valve 84, and the expansion valve 84 is connected to the refrigerant flow path 21 of the heat exchanger 2. The fan blade 82 is located on one side of the condenser 81, and the drive motor 83 is connected to the fan blade 82 to drive the fan blade 82 to rotate and dissipate heat from the condenser 81.

[0079] like Figure 3 As shown, one embodiment of this utility model provides a refrigeration system, which includes the aforementioned refrigeration equipment, a cooling flow path 5, and a storage component 6. The storage component 6 has a storage cavity for containing a cooling medium and a drain port 61 connected to the storage cavity. The storage cavity is connected to the cooling flow path 5, which has a mounting portion 51 for connecting to the device 9 to be cooled. The drain port 61 is connected to the inlet of the cooling medium flow path 22 of the heat exchanger 2 of the refrigeration equipment. The refrigeration system also includes a second connecting flow path 7, through which the storage cavity is connected to the heat exchange cavity 31 of the refrigeration equipment.

[0080] The refrigeration system provided in one embodiment of this utility model uses a cooling medium stored in a storage chamber to cool the device 9 to be cooled through a cooling flow path 5. However, the device 9 to be cooled usually has precise requirements for the temperature of the cooling medium, and a cooling medium with an excessively low temperature can easily damage the device 9. This solution allows the cooling medium in the heat exchange chamber 31, which exchanges heat with the compressor body 1, to flow into the storage chamber, so that this portion of the hot cooling medium exchanges heat with the cooling medium in the storage chamber, thereby increasing the temperature of the cooling medium in the storage chamber. Thus, when the mounting part 51 is connected to the device 9 to be cooled, a cooling medium of a suitable temperature can flow through the cooling flow path 5 to the device 9 to be cooled, achieving cooling of the device 9 without causing damage to it. Simultaneously, a low-temperature cooling medium is prepared using refrigerant in heat exchanger 2 of the refrigeration equipment. This cooling medium is then introduced into the heat exchange chamber 31 of heat exchanger 3 via the heat exchange component 3. By exchanging heat between the outer wall of the compressor body 1 and the heat exchange chamber 31, the compressor exhaust temperature is reduced, thus avoiding the risk of equipment efficiency degradation or damage due to excessively high temperatures. Using heat exchanger 2 to prepare the cooling medium avoids the need for additional energy consumption, reducing energy consumption, lowering operating costs, and improving equipment integration and overall thermal efficiency. By establishing full connectivity between the refrigeration equipment, cooling flow path 5, storage component 6, and the second connecting flow path 7, the refrigeration system achieves efficient management of the cooling medium circulation and an integrated thermal management system. The connection between the storage chamber, the inlet of the cooling medium flow path 22 of heat exchanger 2, and the heat exchange chamber 31 forms a closed loop for cooling medium circulation, improving the utilization efficiency of the cooling medium. This design ensures smooth circulation of the cooling medium throughout the system, effectively absorbing and transferring the heat generated by the compressor body 1 and the equipment 9 to be cooled, achieving comprehensive thermal balance of the system. Therefore, the refrigeration system provided in this embodiment can solve the problem of insufficient heat dissipation of the compressor in the prior art refrigeration equipment.

[0081] Specifically, the equipment to be cooled 9 includes various CNC machine tools, laser equipment, semiconductor manufacturing equipment, energy storage, new energy battery swapping stations and other heat-generating equipment.

[0082] Specifically, the cooling flow path 5 includes a third connecting flow path 52 and a second valve body 53. One end of the third connecting flow path 52 is connected to the cooling medium flow path 22, and the other end is connected to the mounting part 51, so that the cooling medium flows into the device 9 to be cooled. The second valve body 53 is disposed on the third connecting flow path 52, and the opening degree of the second valve body 53 is adjustable. With this structural arrangement, by adjusting the opening degree of the second valve body 53, the system can precisely control the flow rate of the cooling medium flowing into the device 9 to be cooled. The second valve body 53 can automatically adjust its opening degree according to the heat load condition of the device 9 to be cooled, thereby adjusting the flow rate of the cooling medium and realizing adaptive temperature regulation.

[0083] Specifically, when the temperature of the cooling medium in the cooling flow path 5 is too low and it is necessary to increase the temperature of the cooling medium in the cooling flow path 5, the opening degree of the second valve body 53 is set to 0, so that the third connecting flow path 52 is not connected to the mounting part 51. At this time, the first valve body 42 is in the open state. The cooling medium flows from the cooling medium flow path 22 to the heat exchange chamber 31. After exchanging heat with the compressor body 1, the temperature of the cooling medium rises, and then flows into the storage chamber through the second connecting flow path 7 to exchange heat with the cooling medium in the storage chamber, thereby increasing the temperature of the cooling medium in the storage chamber. In this way, the entire liquid circuit does not pass through the device to be cooled 9, but only flows in the circuit of the refrigeration system, forming an internal circulation, which avoids the low temperature liquid from damaging the device to be cooled 9. The second valve body 53 is opened after the temperature of the cooling medium in the internal circulation rises, so that the cooling medium of suitable temperature can be introduced into the device to be cooled 9 to cool it, while ensuring that the device to be cooled 9 is not damaged by the low temperature medium.

[0084] Specifically, the second valve body 53 is a proportional solenoid valve, which has opening, closing, and proportional adjustment functions. The second valve body 53 can also be a combination of a common solenoid valve and an electronic expansion valve, wherein the common solenoid valve controls opening and closing, and the electronic expansion valve controls the opening degree.

[0085] Specifically, the refrigeration equipment includes a first connecting flow path 41 and a first valve body 42 disposed on the first connecting flow path 41. The outlet of the cooling medium flow path 22 is connected to the heat exchange chamber 31 through the first connecting flow path 41. The opening degree of the first valve body 42 is adjustable. The refrigeration equipment also includes a control component. The refrigeration system also includes a second temperature detection component, the detection end of which is disposed on the storage component 6 and used to detect the temperature of the cooling medium in the storage chamber. The first valve body 42, the second valve body 53, and the second temperature detection component are all connected to the control component, which controls the opening degree of the first valve body 42 and the second valve body 53 based on the detection result of the second temperature detection component. With this structural arrangement, the control component intelligently adjusts the opening degree of the first valve body 42 and the second valve body 53 based on the information fed back by the second temperature detection component, achieving coordination between the heat exchange chamber 31 and the compressor body 1 for heat exchange and the cooling requirement of the device 9 to be cooled. The coordinated control of the first valve body 42 and the second valve body 53 can effectively cope with external temperature fluctuations and changes in the heat load of the equipment to be cooled 9, ensuring stable operation of the refrigeration system under various operating conditions, improving the reliability of the system, and reducing failures caused by equipment overheating or improper temperature control.

[0086] Specifically, when the temperature of the cooling medium meets the requirements for use of the device 9 to be cooled, that is, when there is no need to heat the cooling medium, after the refrigeration system is turned on, the second valve body 53 opens and the first valve body 42 closes. The first valve body 42 will only open to cool the compressor when the compressor discharge temperature reaches the preset discharge temperature.

[0087] Specifically, the refrigeration system is a liquid temperature-controlled cooler used to cool the heat-generating equipment 9.

[0088] Specifically, such as Figure 3 As shown, the refrigeration system also includes a booster pump 85, which is disposed between the heat exchanger 2 and the storage unit 6 and located in the cooling flow path 5 to provide power to the cooling medium flowing in the cooling flow path 5.

[0089] like Figure 4 As shown, an embodiment of the present invention provides a control method applicable to the above-mentioned refrigeration system. The control method includes: acquiring the temperature of the cooling medium in the storage cavity; comparing the temperature of the cooling medium in the storage cavity with a preset adjustment temperature; and controlling the on / off connection between the cooling flow path 5 and the device to be cooled 9, and the on / off connection between the cooling medium flow path 22 of the refrigeration device and the heat exchange cavity 31 of the refrigeration device, based on the difference between the temperature of the cooling medium in the storage cavity and the preset adjustment temperature.

[0090] The control method provided in one embodiment of this utility model achieves precise temperature control of the system by real-time monitoring of the temperature of the cooling medium in the storage cavity and comparing it with the preset adjustment temperature. This ensures that the temperature of the cooling medium is always maintained within the optimal range suitable for the operation of the device 9 to be cooled, effectively avoiding equipment damage caused by excessively low temperatures. By controlling the on / off connection between the cooling flow path 5 and the device 9 to be cooled, excessively low-temperature cooling medium can be prevented from flowing into the device 9 and causing damage. By controlling the on / off connection between the cooling medium flow path 22 of the refrigeration equipment and the heat exchange chamber 31 of the refrigeration equipment, the cooling medium in the cooling medium flow path 22 can be better utilized to exchange heat with the compressor, thereby reducing the compressor's exhaust temperature, ensuring the stability of the compressor's operating performance, and simultaneously forming a higher-temperature cooling medium, which facilitates heat exchange with the cooling medium in the storage cavity, thereby increasing the temperature of the cooling medium in the storage cavity. By dynamically adjusting the flow path based on the temperature difference, the system can intelligently optimize energy distribution, reduce unnecessary cooling medium circulation and energy consumption. Especially when the cooling medium temperature is close to a preset value, it can effectively control the cooling medium flow rate, avoiding energy waste caused by over-cooling and improving system energy efficiency. Therefore, the control method provided in this embodiment can solve the problem of insufficient heat dissipation in the compressor of existing refrigeration equipment.

[0091] It should be noted that the specific value of the preset temperature adjustment needs to be adjusted according to the needs of different types of equipment to be cooled.

[0092] In one embodiment, the method for controlling the connection / disconnection between the cooling flow path 5 and the device to be cooled 9, and between the cooling medium flow path 22 of the refrigeration equipment and the heat exchange chamber 31 of the refrigeration equipment, based on the difference between the temperature of the cooling medium in the storage cavity and the preset adjustment temperature, includes: when the difference between the temperature of the cooling medium in the storage cavity and the preset adjustment temperature is greater than the preset adjustment difference, the cooling flow path 5 is disconnected from the device to be cooled 9, and the cooling medium flow path 22 is connected to the heat exchange chamber 31; when the difference between the temperature of the cooling medium in the storage cavity and the preset adjustment temperature is less than or equal to the preset adjustment difference, the cooling flow path 5 is connected to the device to be cooled 9. With this setup, by setting the preset adjustment difference, the method can dynamically adjust the circulation path of the cooling medium in the system, effectively manage temperature deviations, and ensure that the difference between the cooling medium temperature and the preset adjustment temperature is controlled within a reasonable range. This strategy avoids the potential equipment performance problems or overcooling risks that may result from directly supplying the cooling medium to the device to be cooled when the temperature is too low. When the temperature difference between the cooling medium in the storage chamber and the preset adjustment temperature is large, the system disconnects the cooling flow path 5 from the device to be cooled 9, and connects the cooling medium flow path 22 to the heat exchange chamber 31 for internal circulation. This fully utilizes the heat energy generated by the compressor body 1 to raise the temperature of the cooling medium, avoiding the use of high-energy-consuming solutions such as electric auxiliary heating, and improving the system's energy efficiency and heat utilization rate.

[0093] Specifically, when the temperature difference between the cooling medium in the storage cavity and the preset adjustment temperature is less than or equal to the preset adjustment difference, the cooling medium flow path 22 and the heat exchange cavity 31 can be connected or disconnected.

[0094] It should be noted that the specific value of the preset adjustment difference needs to be adjusted according to the requirements of different types of equipment to be cooled. Generally, the preset adjustment difference is less than 3℃.

[0095] In one embodiment, a second valve body 53 is provided between the cooling flow path 5 and the device to be cooled 9, and a first valve body 42 is provided between the heat exchange chamber 31 and the cooling medium flow path 22. The control method further includes: acquiring the on / off state between the cooling flow path 5 and the device to be cooled 9, and the on / off state between the cooling medium flow path 22 and the heat exchange chamber 31; when the cooling flow path 5 is connected to the device to be cooled 9 and the cooling medium flow path 22 is connected to the heat exchange chamber 31, acquiring the exhaust temperature at the refrigerant outlet 12 of the compressor body 1 of the refrigeration equipment, and obtaining the difference between the exhaust temperature and the preset exhaust temperature based on the exhaust temperature; adjusting the opening degree of the first valve body 42 and the second valve body 53 based on the difference between the exhaust temperature and the preset exhaust temperature and the difference between the temperature of the cooling medium in the storage chamber and the preset operating temperature. With this setting, by monitoring the difference between the exhaust temperature of the compressor body 1 and the preset exhaust temperature, and the difference between the temperature of the cooling medium in the storage chamber and the preset operating temperature, fine adjustment of the opening degree of the first valve body 42 and the second valve body 53 is achieved. By acquiring and controlling the on / off states of the cooling flow path 5 and the cooling medium flow path 22 in real time, the system can dynamically adjust the direction of heat energy flow. When the exhaust temperature of the compressor body 1 is too high, the opening of the first valve body 42 is increased to promote more cooling medium to enter the heat exchange chamber 31 for heat exchange, thereby reducing the exhaust temperature; conversely, the opening is decreased to reduce the consumption of cooling medium. Similarly, the opening adjustment of the second valve body 53 is based on the temperature of the cooling medium and the needs of the equipment 9 to be cooled, realizing the effective distribution and management of heat energy, avoiding unnecessary cooling medium circulation and energy waste, and achieving efficient management of the refrigeration system's energy consumption.

[0096] In one embodiment, the method for adjusting the opening of the first valve body 42 and the second valve body 53 based on the difference between the exhaust temperature and a preset exhaust temperature and the difference between the temperature of the cooling medium in the storage cavity and a preset operating temperature includes: when the difference between the exhaust temperature and the preset exhaust temperature is less than or equal to a first preset difference, and the difference between the temperature of the cooling medium in the storage cavity and the preset operating temperature is greater than a second preset difference; or when the difference between the exhaust temperature and the preset exhaust temperature is greater than the first preset difference, and the difference between the temperature of the cooling medium in the storage cavity and the preset operating temperature is less than or equal to the second preset difference. When setting the difference, the opening degree of the first valve body 42 is the same as the opening degree of the second valve body 53. When the difference between the exhaust temperature and the preset exhaust temperature is less than or equal to the first preset difference, and the difference between the temperature of the cooling medium in the storage cavity and the preset operating temperature is less than or equal to the second preset difference, the opening degree of the second valve body 53 is greater than the opening degree of the first valve body 42. When the difference between the exhaust temperature and the preset exhaust temperature is greater than the first preset difference, and the difference between the temperature of the cooling medium in the storage cavity and the preset operating temperature is greater than the second preset difference, the opening degree of the first valve body 42 is greater than the opening degree of the second valve body 53. By setting two preset differences (the first preset difference and the second preset difference), the relationship between the equipment cooling temperature requirement and the compressor heat dissipation requirement can be balanced according to the changes in exhaust temperature and cooling medium temperature. When the compressor's heat dissipation demand exceeds the equipment's cooling temperature requirement (i.e., the difference between the corresponding exhaust temperature and the preset exhaust temperature is greater than the first preset difference, and the difference between the temperature of the cooling medium in the storage chamber and the preset operating temperature is greater than the second preset difference), the system enhances the heat exchange effect on the compressor by making the opening degree of the first valve body 42 greater than the opening degree of the second valve body 53; when the compressor's heat dissipation demand is less than the equipment's cooling temperature requirement (i.e., the difference between the corresponding exhaust temperature and the preset exhaust temperature is less than or equal to the first preset difference, and the difference between the temperature of the cooling medium in the storage chamber and the preset operating temperature is less than or equal to the second preset difference), the second valve body... The opening degree of valve 53 is greater than that of the first valve body 42, thereby enhancing the heat exchange effect on the cooling medium. When the compressor's heat dissipation demand is the same as the equipment's cooling temperature demand (i.e., the difference between the corresponding exhaust temperature and the preset exhaust temperature is less than or equal to the first preset difference, and the difference between the temperature of the cooling medium in the storage cavity and the preset operating temperature is greater than the second preset difference, or the difference between the exhaust temperature and the preset exhaust temperature is greater than the first preset difference, and the difference between the temperature of the cooling medium in the storage cavity and the preset operating temperature is less than or equal to the second preset difference), the opening degree of the first valve body 42 is the same as that of the second valve body 53 to ensure simultaneous response to the two demands.

[0097] It should be noted that the preset operating temperature corresponds to the cooling temperature required by the cooling medium of the device 9 to be cooled, which is connected to the mounting unit 51. The specific value of the preset operating temperature needs to be obtained by adjusting according to the requirements of different types of devices 9 to be cooled.

[0098] It should be noted that, in order to ensure the normal operation of the refrigeration system and form a medium loop, at least one of the first valve body 42 and the second valve body 53 needs to be in the open state. That is, when the first valve body 42 is opened due to the heat dissipation requirements of the compressor, the second valve body 53 can be opened or closed; when the second valve body 53 is opened due to the increased temperature requirements of the cooling medium of the device 9 to be cooled, the first valve body 42 can be opened or closed.

[0099] It should be noted that when the second valve body 53 is open, the temperature of the cooling medium in the storage chamber is necessarily greater than or equal to the preset operating temperature. That is, the temperature of the cooling medium flowing in the cooling flow path 5 will not be too low and damage the equipment 9 to be cooled. At this time, the greater the temperature difference between the cooling medium in the storage chamber and the preset operating temperature, the smaller the need to increase the temperature of the cooling medium.

[0100] One embodiment of this utility model provides a control device applicable to the above-described control method. The control device includes an acquisition unit, a judgment unit, and a control unit. The acquisition unit is used to acquire the temperature of the cooling medium in the storage cavity; the judgment unit is used to compare the temperature of the cooling medium in the storage cavity with a preset adjustment temperature; the control unit is used to control the on / off state between the cooling flow path 5 and the device to be cooled 9, and between the cooling medium flow path 22 of the refrigeration device and the heat exchange cavity 31 of the refrigeration device, based on the difference between the temperature of the cooling medium in the storage cavity and the preset adjustment temperature.

[0101] One embodiment of this utility model provides a non-volatile storage medium, which includes a stored program, wherein the program controls the device where the non-volatile storage medium is located to execute the above-described control method during runtime.
