The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

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

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

[0023] like Figure 1-3 As shown, a portable internal circulation heat exchanger device comprises a shell 1, on which a controller is provided, on the outer wall of the shell 1 are provided an input connector 2 and an output connector 3 connected to a liquid cooling plate, the liquid cooling plate is used to dissipate heat for an external heating device, 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 a 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, 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 of the coolant flowing into the radiator 9, and the proportional valve 7 is used to control the flow 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, and the liquid cooling plate is laid on the external heating device to exchange heat with the heating 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 cooling liquid with the increased temperature in the liquid cooling plate to flow into the liquid storage tank 4 through the input connector 2. The cooling liquid 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 the heat of the cooling liquid, so that the temperature of the cooling liquid decreases. The cooling liquid after the temperature decreases will flow into the output connector 3 through the pipeline, and then flow back into the liquid cooling plate, so that the cooling liquid can circulate. The cooling liquid is circulated between the heat exchanger and the liquid cooling plate by the liquid pump 5, and the cooling liquid is dissipated by the radiator 9, so that the cooling liquid flowing into the liquid cooling plate can exchange heat with the external heating device, thereby achieving the purpose of dissipating the heat of the external heating 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, and the controller 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 relatively 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 consumption working state for a long time, reducing the energy consumption of the heat exchanger, and saving production costs.

[0026] The portable internal circulation heat exchanger device integrates all mechanical structures such as the liquid storage tank 4 and the liquid pump 5 into the housing 1, thereby reducing the overall volume of the heat exchanger, improving portability, and facilitating installation, handling and transportation. The flow rate of the coolant in the heat exchanger can be detected in real time through the cooperation of the flow meter 8 and the proportional valve 7, and the operation of the radiator 9 can be controlled to achieve precise control of the temperature and flow of the coolant, reduce energy consumption, and meet the processing requirements of energy saving and environmental protection.

[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, which 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, and 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; the cooling fan 91 is controlled to blow air onto the liquid cooling row 92, so that the coolant in the liquid cooling row 92 exchanges heat with the cold air, so that the temperature of the coolant in the liquid cooling row 92 decreases, 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 the speed, otherwise the cooling fan 91 can be controlled to reduce the speed.

[0029] In order to improve the efficiency of heat dissipation, in this embodiment, there are two liquid cooling radiators 92, and the two liquid cooling radiators 92 are arranged side by side in the housing 1, and 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 liquid storage tank 10 is installed on the housing 1, the output end of the radiator 9 is connected to the liquid storage tank 10, and the output connector 3 is connected to the liquid storage tank 10. The liquid storage tank 10 is used to temporarily store the cooled coolant. In actual use, the coolant cooled by the radiator 9 will flow into the liquid storage tank 10, and the cooled coolant can be temporarily stored by the liquid storage tank 10 to ensure that when the proportional valve 7 adjusts the flow of the coolant, the coolant in the heat exchanger can flow smoothly. Specifically, when the proportional valve 7 reduces the flow of the coolant flowing into the radiator 9, the flow of the coolant flowing into the radiator 9 will be less than the outflow flow, and the excess coolant will be temporarily stored in the liquid storage tank 10; when the proportional valve 7 increases the flow of the coolant flowing into the radiator 9, the flow of the coolant flowing into the radiator 9 will be greater than the outflow flow, and the coolant in the liquid storage tank 10 will be supplemented and flow into the liquid cooling plate, thereby ensuring that there is enough coolant flowing into the liquid cooling plate, improving the stability of the work.

[0031] A second temperature sensor 11 is provided between the liquid storage tank 10 and the radiator 9. The 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 temperature of the coolant flowing out of the radiator 9 by the second temperature sensor 11, the working result of the radiator 9 can be judged, thereby judging whether the radiator 9 dissipates the coolant to a predetermined temperature. If the temperature is too high, the cooling fan 91 can be controlled to increase the speed. If the temperature is too low, the cooling fan 91 can be controlled to reduce the speed. Through the coordinated control of the two temperature sensors, the control accuracy of the heat exchanger for the heat dissipation temperature can be improved, and the working stability can be improved.

[0032] In actual use, the coolant will evaporate during the flow process, so it is necessary to add coolant to the heat exchanger from time to time. In this embodiment, a liquid injection port 41 is provided on the liquid storage tank 4, and a sealing plug 42 is provided on the liquid injection port 41. The sealing plug 42 is detachably sealed and connected to the liquid injection port 41. When it is necessary to add coolant, it is only necessary to pull out the sealing plug 42 from the liquid injection port 41, and then pour new coolant into the liquid storage tank 4 through the liquid injection port 41, and then re-cover 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. Normally, 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 a 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 touch screen control panel 14 fixedly installed in the housing 1. The power adapter 13 is used for external power supply and can convert the mains electricity into the voltage and current required by the heat exchanger. The power adapter 13 is electrically connected to the touch screen control panel 14. The touch screen control panel 14 extends out of the side of the housing 1. A control system, such as a PLC control system, is integrated in the touch screen control panel 14. The heat exchanger can be controlled to work or shut down by operating the touch screen control panel 14. At the same time, the touch screen can also display the working status of the heat exchanger in real time for the operator to view.

[0035] An indicator light 15 is installed on one side of the housing 1, and the indicator light 15 is electrically connected to the touch screen control panel 14. The indicator light 15 can be used to indicate the working state 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, and 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] The portable internal circulation heat exchanger device integrates mechanical devices such as the liquid pump 5 and the liquid storage tank 4 into the shell 1, thereby reducing the overall volume of the heat exchanger; and a handle 16 is installed on the outside of the shell 1, thereby improving the portability of the heat exchanger, facilitating transportation and installation, so that it can meet the installation and use requirements of a smaller space. 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 to improve the accuracy of temperature and flow regulation; and through the cooperation of the radiator 9 and the proportional valve 7, the workload can be adjusted according to the actual working conditions, thereby reducing the working energy consumption of the heat exchanger, saving costs, and meeting the processing requirements of energy saving and environmental protection.

All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
