[0017] 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.

[0018] Please see Figure 1-3 This utility model provides an embodiment of a cold storage linear cooling high and low temperature testing machine, including a testing component 2, which includes a water tank 20 and a cold storage box 24; antifreeze is introduced into the water tank 20 through a first pipeline 213 on one side of the water tank 20, and the antifreeze in the water tank 20 is led out through a second pipeline 214; thus, the antifreeze inside the water tank 20 can circulate. Furthermore, the cold storage tank 24 is connected to the first pipeline 213 via a third pipeline 216, and the cold storage tank 24 is also connected to the second pipeline 214 via a fourth pipeline 217. The antifreeze in the cold storage tank 24 is delivered to the water tank 20 via the output component 21. Therefore, the cold storage tank 24 can be used to store antifreeze, and then the antifreeze can be delivered to the water tank 20 via the output component 21 to regulate the temperature of the antifreeze in the water tank 20 and keep the temperature of the antifreeze in the water tank 20 constant.

[0019] Meanwhile, a water supply pipe 25 is also provided on the side of the water tank 20 away from the first pipeline 213, and the antifreeze in the water tank 20 is transported to the client through the water supply pipe 25. Since the water temperature inside the water tank 20 is continuously regulated by the cold storage tank 24, the water temperature at the client is kept constant. In addition, the antifreeze passing through the client is diverted back to the water tank 20 through the provided return water pipe 26. Therefore, by utilizing the circulation of the antifreeze, the temperature of the antifreeze can be maintained for a long time to meet the requirements of linear cooling.

[0020] To cool the antifreeze, a refrigeration assembly 1 is also included. The refrigeration assembly 1 includes a heat exchanger 13. The hot-side outlet 14 of the heat exchanger 13 is connected to the first pipeline 213, and the hot-side inlet 15 of the heat exchanger 13 is connected to the second pipeline 214. Therefore, the first pipeline 213 and the second pipeline 214 can be used to connect the heat exchanger 13 to the water tank 20, allowing the antifreeze to flow between the heat exchanger 13 and the water tank 20. Furthermore, since a second pump 28 is also provided on the second pipeline 214, and the second pump 28 causes the antifreeze to circulate between the cold storage tank 24 and the heat exchanger 13, the operation of the second pump 28 can be used to circulate the antifreeze between the heat exchanger 13 and the water tank 20, thereby facilitating heat exchange within the heat exchanger 13. In particular, the flow rate of the antifreeze can be increased by adjusting the rotation speed of the second pump 28, thus controlling the antifreeze temperature.

[0021] Since the end of the third pipeline 216 away from the cold storage tank 24 is connected to the first three-way valve 210 on the first pipeline 213, and the end of the fourth pipeline 217 away from the cold storage tank 24 is connected to the second three-way valve 212 on the second pipeline 214, the flow direction of the antifreeze can be adjusted by opening and closing the two three-way valves. For example, when the A / B ports of the first three-way valve 210 and the second three-way valve 212 are connected, the antifreeze circulates between the heat exchanger 13 and the cold storage tank 24. In addition, the cold storage tank 24 is also equipped with a liquid level sensor 215. Therefore, when the liquid level inside the cold storage tank 24 reaches a preset value, the liquid level sensor 215 outputs a signal, and then the controller causes the A / B ports of the first three-way valve 210 and the second three-way valve 212 to be closed, so that the antifreeze in the cold storage tank 24 no longer participates in the antifreeze circulation.

[0022] When the customer needs to conduct a linear cooling experiment, the A / B ports of the first three-way valve 210 and the second three-way valve 212 are connected in advance, and the pipelines between the second pump body 28, the heat exchanger 13 and the cold storage tank 24 are connected. Then, the refrigeration component 1 is started, and the refrigeration component 1 cools down the antifreeze in the cold storage tank 24. When the antifreeze in the cold storage tank 24 drops to the predetermined temperature, the A / C ports of the first three-way valve 210 and the second three-way valve 212 are connected to start the linear cooling experiment.

[0023] At the start of the experiment, the second pump 28, the third pump 211, and the refrigeration component 1 are activated, supplying antifreeze at a suitable temperature to the client. In the early stages of the experiment, the refrigeration component 1 has a large cooling capacity, which can be met by adjusting the power of the heating element 29 to satisfy the required cooling. Later in the experiment, when the cooling capacity of the refrigeration component 1 is insufficient to meet the cooling demand, the flow rate of the first pump 23 is adjusted to meet the linear cooling requirement. For example, if the cold storage tank is pre-cooled to a low temperature, such as -50℃, during the linear cooling process, the refrigeration component 1 may not be able to meet the linear requirement at -20℃. Since the antifreeze temperature in the cold storage tank 24 is low, the speed of the first pump 23 is adjusted to transfer the lower-temperature antifreeze from the cold storage tank 24 to the water tank 20 to compensate for the insufficient cooling capacity of the refrigeration component 1 and achieve the linear cooling requirement. The first three-way valve 210 and the second three-way valve 212 are preferably electrically operated three-way valves.

[0024] Furthermore, since the output component 21 includes an output pipeline 22 and a first pump body 23 is provided to cause the antifreeze in the cold storage tank 24 to flow into the water tank 20, the speed at which the antifreeze in the cold storage tank 24 flows into the water tank 20 can be adjusted and controlled by controlling the opening and closing of the first pump body 23 and its rotation speed.

[0025] Furthermore, since the water tank 20 is also equipped with a heating element 29 for heating the antifreeze, when high-temperature testing is required, the heating element 29 is used to heat the coolant in the water tank 20 to meet the client's high-temperature testing requirements. Based on this, the device can perform both low-temperature and high-temperature testing. In addition, the temperature of the coolant can also be adjusted through the heating element 29.

[0026] In addition, a third pump body 211 is provided on the water supply pipe 25. Therefore, the third pump body 211 can be used to drive the antifreeze to the client. At the same time, the delivery volume can be controlled by controlling the rotation speed of the third pump body 211. A temperature sensor 27 is provided on the side of the third pump body 211 away from the water tank 20. Therefore, the temperature of the antifreeze output from the water supply pipe 25 can be monitored in real time so that the user can obtain the temperature of the antifreeze when it is output.

[0027] Based on the above scheme, the cold-side outlet of the heat exchanger 13 is connected to the compressor 10, and the outlet of the compressor 10 is connected to the condenser 11. The condenser 11 is connected to the cold-side inlet of the heat exchanger 13 via a sixth pipeline 16. Therefore, the compressor 10 can be used to circulate the refrigerant between the compressor 10, the condenser 11, and the heat exchanger 13 to facilitate heat exchange between the refrigerant and the antifreeze. Simultaneously, an electronic expansion valve 12 is installed on the sixth pipeline 16 between the condenser 11 and the heat exchanger 13. Therefore, the electronic expansion valve 12 can be used to further reduce the refrigerant temperature, widen the temperature difference between the refrigerant and the antifreeze, and thus give the device a larger temperature regulation range.

[0028] Furthermore, a seventh pipeline 218 is provided between the water tank 20 and the cold storage tank 24, and the coolant in the water tank 20 is guided back to the cold storage tank 24 through the seventh pipeline 218. Based on this, the antifreeze circulates between the heat exchanger 13 and the water tank 20. At the same time, the circulation of antifreeze between the cold storage tank 24 and the water tank 20 is achieved by the conveying component 21 and the seventh pipeline 218, which provides cooling supplement for the circulation of antifreeze between the heat exchanger 13 and the water tank 20, so as to solve the problem that the cooling rate is not enough by relying solely on the circulation of antifreeze between the heat exchanger 13 and the water tank 20.

[0029] 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.
