This is achieved by installing a liquid cooling plate on the heat-generating server and then equipping it with a liquid cooling heat exchanger to exchange heat with the liquid within the plate. However, existing heat exchangers are often bulky and complex to operate, making them difficult to install and transport. Furthermore, the lack of internal detection devices makes it difficult to accurately control temperature and flow, resulting in high energy consumption. Utility Model Content

[0021] References to "embodiments" in this disclosure mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to mutually exclusive, independent, or alternative embodiments to other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0022] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, a portable internal circulation heat exchanger device includes a shell 1, on which a controller is provided, and an input connector 2 and an output connector 3 for connecting a liquid cooling plate are provided on the outer wall of the shell 1. The liquid cooling plate is used to dissipate heat for external heating devices. A liquid storage tank 4, a liquid pump 5, a first temperature sensor 6, a proportional valve 7, a flow meter 8 and a radiator 9 are fixedly installed in the shell 1. The liquid storage tank 4 is used to hold coolant, the input connector 2 is connected to the liquid storage tank 4, the liquid pump 5, the first temperature sensor 6, the proportional valve 7, the flow meter 8 and the radiator 9 are respectively electrically connected to the controller, the input end of the liquid pump 5 is connected to the liquid storage tank 4, the output end of the liquid pump 5 is connected to the input end of the radiator 9, and the output end of the radiator 9 is connected to the output connector 3, the first temperature sensor 6, the proportional valve 7 and the flow meter 8 are respectively arranged between the liquid storage tank 4 and the radiator 9, the first temperature sensor 6 is used to detect the temperature of the coolant flowing into the radiator 9, the flow meter 8 is used to detect the flow rate of the coolant flowing into the radiator 9, and the proportional valve 7 is used to control the flow rate of the coolant flowing into the radiator 9.

[0024] During specific operation, the input connector 2 and the output connector 3 are respectively connected to the liquid cooling plate. The liquid cooling plate is placed on an external heat-generating device and exchanges heat with the heat-generating device, so that the temperature of the coolant on the liquid cooling plate will increase. The controller controls the operation of the liquid pump 5 and the radiator 9 respectively. The operation of the liquid pump 5 causes the coolant with a high temperature in the liquid cooling plate to flow into the liquid storage tank 4 through the input connector 2. The coolant in the liquid storage tank 4 flows into the liquid pump 5 through the pipeline, and then flows into the radiator 9 through the liquid pump 5. The radiator 9 works to dissipate heat from the coolant, thereby causing the temperature of the coolant to drop. The coolant after the temperature drops will flow into the output connector 3 through the pipeline, and then flow back into the liquid cooling plate, thereby causing the coolant to circulate. The liquid pump 5 causes the coolant to circulate between the heat exchanger and the liquid cooling plate, and the radiator 9 dissipates heat from the coolant, so that the coolant flowing into the liquid cooling plate can exchange heat with the external heat-generating device, thereby achieving the purpose of dissipating heat from the external heat-generating device.

[0025] During operation, the first temperature sensor 6 will monitor the temperature of the coolant flowing into the radiator 9 through the input connector 2 in real time. If the temperature is relatively high, a feedback signal will be sent to the controller, which will control the radiator 9 to increase the working power and speed up the heat dissipation of the coolant. At the same time, the controller can also control the proportional valve 7 to reduce the flow of the coolant, thereby improving the heat dissipation performance of the coolant. If the temperature detected by the first temperature sensor 6 is low, the controller can reduce the working power of the radiator 9 to reduce energy consumption. At the same time, the proportional valve 7 is controlled to increase the flow of the coolant. At the same time, the flow meter 8 also detects the flow of the coolant flowing into the radiator 9 in real time, thereby achieving the purpose of accurately controlling the flow of the coolant. It can be seen that the portable internal circulation heat exchanger device can adjust the working power of the radiator 9 in real time according to the temperature of the internal coolant, thereby avoiding the radiator 9 from being in a high-power working state for a long time, reducing the energy consumption of the heat exchanger, and saving production costs.

[0026] This portable internal-circulation heat exchanger integrates all mechanical components, including a liquid storage tank 4 and a liquid extraction pump 5, into a housing 1, reducing the heat exchanger's overall size and improving portability, making installation, handling, and transportation easier. A flow meter 8 and a proportional valve 7 monitor the coolant flow rate within the heat exchanger in real time. By controlling the operation of a radiator 9, the coolant's temperature and flow rate can be precisely controlled, reducing energy consumption and meeting energy-saving and environmentally friendly manufacturing requirements.

[0027] In this embodiment, the coolant is deionized water or a 20%-30% ethylene glycol solution; in other embodiments, the coolant may also be other liquids with good thermal conductivity.

[0028] In this embodiment, the radiator 9 includes a cooling fan 91 and a liquid cooling row 92. The cooling fan 91 and the liquid cooling row 92 are respectively installed in the housing 1. The cooling fan 91 is electrically connected to the controller. The input end of the liquid cooling row 92 is connected to the output end of the liquid pump 5. The output end of the liquid cooling row 92 is connected to the output connector 3. The cooling fan 91 is used to blow air onto the liquid cooling row 92. During operation, the liquid pump 5 delivers high-temperature coolant to the liquid cooling row 92; by controlling the cooling fan 91 to blow air onto the liquid cooling row 92, the coolant in the liquid cooling row 92 is heat-exchanged with the cold air, causing the temperature of the coolant in the liquid cooling row 92 to drop, thereby achieving the purpose of cooling the coolant. If the temperature of the coolant is high, the cooling fan 91 can be controlled to increase its speed. Otherwise, the cooling fan 91 can be controlled to decrease its speed.

[0029] To improve heat dissipation efficiency, in this embodiment, two liquid cooling radiators 92 are provided, and the two liquid cooling radiators 92 are arranged side by side within the housing 1. Two cooling fans 91 are installed on each liquid cooling radiator 92. In other embodiments, the number of liquid cooling radiators 92 and cooling fans 91 can also be any other number.

[0030] A reservoir tank 10 is mounted on the housing 1. The output end of the radiator 9 is connected to the reservoir tank 10, and the output connector 3 is also connected to the reservoir tank 10. The reservoir tank 10 is used to temporarily store cooled coolant. During actual use, the coolant cooled by the radiator 9 flows into the reservoir tank 10. This reservoir tank 10 can temporarily store the cooled coolant, ensuring smooth coolant flow within the heat exchanger when the proportional valve 7 adjusts the coolant flow. Specifically, when the proportional valve 7 reduces the coolant flow into the radiator 9, the coolant flow into the radiator 9 will be less than the coolant flow out, and the excess coolant will be temporarily stored in the reservoir tank 10. When the proportional valve 7 increases the coolant flow into the radiator 9, the coolant flow into the radiator 9 will be greater than the coolant flow out, and the coolant in the reservoir tank 10 will flow into the liquid cooling plate, thereby ensuring sufficient coolant flow to the liquid cooling plate and improving operational stability.

[0031] A second temperature sensor 11 is installed between the reservoir 10 and the radiator 9. This second temperature sensor 11 is connected to the controller and is used to detect the temperature of the coolant flowing out of the radiator 9. By detecting the coolant temperature flowing out of the radiator 9 through the second temperature sensor 11, the radiator 9's operating results can be determined, thereby determining whether the radiator 9 has dissipated the coolant to a predetermined temperature. If the temperature is too high, the cooling fan 91 can be controlled to increase its speed; if the temperature is too low, the cooling fan 91 can be controlled to decrease its speed. The coordinated control of the two temperature sensors improves the heat exchanger's control of the cooling temperature and enhances operational stability.

[0032] During actual use, the coolant evaporates as it flows, necessitating occasional additions to the heat exchanger. In this embodiment, the reservoir 4 is provided with a liquid filling port 41, which is provided with a sealing plug 42. The sealing plug 42 is removably and hermetically connected to the liquid filling port 41. To add coolant, simply remove the sealing plug 42 from the liquid filling port 41, pour new coolant into the reservoir 4 through the liquid filling port 41, and then replace the sealing plug 42.

[0033] In this embodiment, a backup water pump 12 is also installed in the shell 1. The backup water pump 12 is connected to the controller, the input end of the backup water pump 12 is connected to the liquid storage tank 4, and the output end of the backup water pump 12 is connected to the input end of the radiator 9. Under normal circumstances, the backup water pump 12 is not working; the backup water pump 12 only needs to work when the liquid pump 5 fails. Specifically, when the liquid pump 5 fails, the backup water pump 12 can be controlled by the controller to work, thereby ensuring that the heat exchanger can continue to work stably and avoiding the situation where the external heating device heats up and burns out due to sudden failure. By providing the backup water pump 12, the working stability of the heat exchanger is improved, the risk of burning out of the heating device is reduced, and the loss is reduced.

[0034] The controller includes a power adapter 13 and a touchscreen control panel 14, which are fixedly mounted within the housing 1. The power adapter 13 is used as an external power source, converting mains electricity to the voltage and current required by the heat exchanger. The power adapter 13 is electrically connected to the touchscreen control panel 14, which extends out of the side of the housing 1 and integrates a control system, such as a PLC. The heat exchanger can be turned on or off by operating the touchscreen control panel 14. The touchscreen also displays the heat exchanger's operating status in real time for easy viewing by the operator.

[0035] An indicator light 15 is installed on one side of the housing 1 and is electrically connected to the touch screen control panel 14. The indicator light 15 can be used to indicate the working status of the heat exchanger; for example, a green light indicates normal operation, a red light indicates a fault, etc.

[0036] In order to facilitate carrying and transporting the heat exchanger, in this embodiment, a handle 16 is fixedly provided on the side wall of the shell 1. The user can easily pick up the heat exchanger by holding the handle 16, thereby further improving the portability of the heat exchanger and facilitating installation and transportation.

[0037] This portable internal circulation heat exchanger integrates mechanical devices such as the liquid extraction pump 5 and the liquid storage tank 4 within the housing 1, thereby reducing the overall volume of the heat exchanger. A handle 16 is installed on the outside of the housing 1, thereby improving the portability of the heat exchanger, facilitating transportation and installation, and meeting the requirements of installation and use in smaller spaces. In addition, by installing multiple temperature sensors and flow meters 8, the flow and temperature of the coolant in the heat exchanger can be monitored, improving the accuracy of temperature and flow regulation. The radiator 9 and proportional valve 7 cooperate to adjust the workload according to actual working conditions, thereby reducing the heat exchanger's operating energy consumption, saving costs, and meeting energy-saving and environmentally friendly processing requirements.

[0038] The above-mentioned specific implementation manner is a preferred implementation manner of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation manner. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
