[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0015] Please see Figure 1 This utility model provides an embodiment of a temperature control testing device, including a test piece 1 and a microchannel radiator 18; a first pipe 2 is provided on one side of the test piece 1 and connected to the outlet of the microchannel radiator 18; a second pipe 3 is provided on the other side of the test piece 1; the other end of the second pipe 3 is connected to a water tank 13, and a heater 12 is also provided in the water tank 13; the water tank 13 is connected to a water pump 14 through a third pipe 16, and the water pump 14 is connected to the inlet of the microchannel radiator 18 through a fourth pipe 5; a three-way proportional valve 15 is also provided on the fourth pipe 5, and one connection port of the three-way proportional valve 15 is connected to the first pipe 2 through a fifth pipe 17.

[0016] In summary, compared with conventional heat exchangers, microchannel heat exchangers are not only smaller in size and have a higher heat transfer coefficient and higher heat transfer efficiency, meeting higher energy efficiency standards, but also possess excellent pressure resistance. In particular, precise temperature control can be achieved by controlling the microchannel radiator and simultaneously adjusting the heater to regulate the heating temperature, and by using a three-way proportional control valve to adjust the flow rate.

[0017] Furthermore, it also includes a fan 19, and through the operation of the fan 19, airflow is forced to flow through the microchannel radiator 18. Therefore, the rotation of the fan 19 can accelerate the flow of airflow, thereby improving the heat dissipation capacity of the microchannel radiator 18.

[0018] Since both the first pipe 2 and the third pipe 16 are equipped with gate valves 4, the flow rate of the liquid in the first pipe 2 and the third pipe 16 can be controlled or the flow of the liquid can be cut off by the gate valves 4. Therefore, by controlling the flow rate of the liquid or stopping the flow of the liquid, the temperature of the liquid can be increased. For example, when the flow of the liquid is stopped, the liquid inside the water tank 13 is heated by the heater 12 to increase the temperature of the liquid.

[0019] Based on the above scheme, in order to obtain liquid-related data in real time and accurately, the first pipe 2 is equipped with a first temperature sensor 6, a first pressure sensor 8 and a first flow sensor 10 in sequence. Therefore, the user can accurately obtain the temperature data, pressure data and flow data of the liquid in the first pipe 2.

[0020] Furthermore, since the second temperature sensor 7 and the second pressure sensor 9 are connected in series on the second pipe 3, the user can also obtain the temperature and pressure data on the third pipe 16 in real time.

[0021] Meanwhile, a third temperature sensor 11 is also provided on the water tank 13, so the water temperature data in the water tank 13 can be obtained in real time using the third temperature sensor 11.

[0022] Specifically, the microchannel heat sink 18, fan 19, heater 12, first temperature sensor 6, first pressure sensor 8, first flow sensor 10, second temperature sensor 7, second pressure sensor 9 and third temperature sensor 11 are all connected to an external PLC controller via wires.

[0023] In summary, by sending the feedback signal from the first temperature sensor 6 to the PLC controller, the PLC calculates the temperature using PID control and controls the speed of the fan 19 on one side of the microchannel heat sink 18 while simultaneously adjusting the on / off state of the solid-state relay of the heater 12 to regulate the heating power, thus achieving precise temperature control.

[0024] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
