Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving cooling, in particular to an energy-saving cooling device for testing. Background Art

[0002] After production, motors and other equipment are subject to a series of tests before they can be shipped. Many devices generate heat during testing, and some require cooling fluids to maintain temperature.

[0003] In the related art, the coolant circulation of the current cooling system is usually carried out by a main pump responsible for the circulation of the coolant, and the outlet can be divided into multiple outlets, and the flow rate of the coolant required by the equipment can be controlled by adjusting the valve; according to the difference in test conditions, the heat generation of the equipment during the test is not consistent. Most tests are operated at low power, at this time the heat generation is small, and only a small flow rate of coolant is required. When operating at rated power or overload, there is also a specified flow rate, and the specified flow rate is mostly less than the total flow rate of the main pump. In this way, during the test process, the main pump is always running at rated power, and in most cases the flow rate supplied to the equipment is small. The excess coolant pumped out can only return to the main pump or the cooling oil tank through the bypass, which greatly wastes energy and causes high equipment testing and production costs. Utility Model Content

[0004] The purpose of the present invention is to provide an energy-saving cooling device for testing, so as to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An experimental energy-saving cooling device, comprising:

[0007] Main pump, frequency converter, power switch, first equipment, second equipment and heat exchange system;

[0008] A three-way valve is provided at one end of the main pump, and two ends of the three-way valve are respectively connected to a first valve and a second valve;

[0009] The first valve is in communication with the first device, and the second valve is in communication with the second device;

[0010] The first device and the second device are respectively in communication with a heat exchange system, and the heat exchange system is in communication with the main pump;

[0011] A cooling oil tank is provided between the heat exchange system and the main pump.

[0012] The energy-saving cooling device for testing according to this scheme has at least the following technical effects:

[0013] The energy-saving cooling device for the test can control the speed of the main pump's variable frequency motor through the frequency converter, so that the coolant flow output by the main pump can be adjusted according to the working conditions of the equipment test, which improves the adaptability and flexibility of the device. Compared with the rated power operation of the traditional main pump, it can effectively avoid high power providing small flow, so that the remaining coolant returns to the cooling tank or the main pump, causing energy waste; it can effectively meet the different flow rates of coolant required by the equipment during the test, and can save energy and reduce the testing and production costs of the product.

[0014] As a further solution of the present invention: a flow meter is respectively provided between the first valve and the first device and between the second valve and the second device.

[0015] By respectively arranging flow meters between the first valve and the first device and between the second valve and the second device, the output of the coolant delivered to the first device through the first valve and to the second device through the second valve can be monitored in real time, and the flow output of the valve can be adjusted according to the coolant required for the actual product test, ensuring that the output of the coolant matches the test requirements and avoiding excess or deficiency, thereby achieving real-time monitoring and precise adjustment of the coolant flow and improving the accuracy of the test results.

[0016] As a further solution of the present invention: an oil filtering device is respectively provided between the first valve and the first device, and between the second valve and the second device.

[0017] During the repeated circulation process, the coolant will produce pollutants such as particles and impurities. By respectively arranging oil filtering devices between the first valve and the first device and between the second valve and the second device, particles, impurities and other pollutants in the coolant can be effectively filtered out, thereby reducing the thermal resistance of the heat exchange system and improving the heat exchange efficiency. At the same time, it can prevent the valve from being blocked, ensure the flow efficiency of the coolant, and accurately control the coolant flow rate.

[0018] As a further solution of the present invention: the control flow rate of the main pump coolant is 0L / min-30L / min.

[0019] Since the control flow rate of the main pump coolant is 0L / min-30L / min, the main pump can meet different test requirements and working conditions. The coolant supply amount can be adjusted and controlled by the frequency converter, which can avoid the main pump using high power to provide test coolant that only requires a small flow rate, and prevent the remaining coolant flow from flowing back to the main pump or cooling oil tank, effectively saving energy and reducing product testing and production costs.

[0020] As a further solution of the present invention: the control flow rate of the coolant of the first valve and the second valve is 0L / min-30L / min respectively.

[0021] Since the control flow rates of the coolant in the first valve and the second valve are 0L / min-30L / min respectively, when one of the first valve and the second valve is in operation, the control flow value corresponding to the main pump can be supplied according to the control flow rate of the main pump; when the first valve and the second valve are in operation at the same time, the sum of the control flow values ​​of the first valve and the second valve is equal to the upper limit of the control flow value of the main pump at that time.

[0032] like Figure 1 The embodiment of the utility model shown is an energy-saving cooling device for testing, comprising: a main pump 1, a frequency converter 2, a power switch 3, a first device 4, a second device 5 and a heat exchange system 6; a three-way valve 7 is provided at one end of the main pump 1, and the two ends of the three-way valve 7 are respectively connected to a first valve 8 and a second valve 9; the first valve 8 is connected to the first device 4, and the second valve 9 is connected to the second device 5; the first device 4 and the second device 5 are respectively connected to the heat exchange system 6, and the heat exchange system 6 is connected to the main pump 1; a cooling oil tank 10 is provided between the heat exchange system 6 and the main pump 1.

[0033] Specifically, the energy-saving cooling device for the test can control the speed of the variable frequency motor of the main pump 1 through the frequency converter 2, so that the coolant flow output by the main pump 1 can be adjusted according to the working conditions of the equipment test, thereby improving the adaptability and flexibility of the device. Compared with the rated power operation of the traditional main pump, it can effectively avoid high power providing small flow, so that the remaining coolant returns to the cooling tank 10 or the main pump 1, causing energy waste; it can effectively meet the different flow rates of coolant required by the equipment during the test, and can save energy and reduce the testing and production costs of the product.

[0034] Furthermore, flow meters 11 are respectively provided between the first valve 8 and the first device 4 and between the second valve 9 and the second device 5 .

[0035] Specifically, by respectively arranging flow meters 11 between the first valve 8 and the first device 4 and between the second valve 9 and the second device 5, the output of the coolant delivered to the first device 4 through the first valve 8 and to the second device 5 through the second valve 9 can be monitored in real time, and the flow output of the valve can be adjusted according to the coolant required for the actual product test to ensure that the output of the coolant matches the test requirements and avoid excess or deficiency, thereby realizing real-time monitoring and precise adjustment of the coolant flow and improving the accuracy of the test results.

[0036] like Figure 1 As shown, an oil filter device 12 is provided between the first valve 8 and the first device 4 and between the second valve 9 and the second device 5 .

[0037] Specifically, the coolant will produce pollutants such as particles and impurities during the repeated circulation process. By respectively arranging the oil filter device 12 between the first valve 8 and the first device 4 and between the second valve 9 and the second device 5, the particles, impurities and other pollutants in the coolant can be effectively filtered out, the thermal resistance of the heat exchange system can be reduced, and the heat exchange efficiency can be improved. At the same time, the valve can be prevented from being blocked, ensuring the flow efficiency of the coolant and the precise control of the coolant flow rate.

[0038] According to an embodiment of the present invention, the control flow rate of the coolant of the main pump 1 is 0L / min-30L / min.

[0039] Specifically, since the control flow rate of the coolant of the main pump 1 is 0L / min-30L / min, the main pump 1 can meet different test requirements and working conditions, and the coolant supply amount can be adjusted and controlled by the frequency converter 2, which can avoid the main pump 1 using high power to provide test coolant that only requires a small flow rate, and prevent the remaining coolant flow from flowing back to the main pump 1 or the cooling oil tank 10, effectively saving energy and reducing the test and production costs of the product.

[0040] Furthermore, the control flow rates of the coolant of the first valve 8 and the second valve 9 are 0 L / min-30 L / min respectively.

[0041] Specifically, since the control flow rates of the coolant of the first valve 8 and the second valve 9 are 0 L / min-30 L / min respectively, when one of the first valve 8 and the second valve 9 is in operation, the control flow value corresponding to the main pump can be supplied according to the control flow rate of the main pump 1; when the first valve 8 and the second valve 9 are in operation at the same time, the sum of the control flow values ​​of the first valve 8 and the second valve 9 is equal to the upper limit of the control flow value of the main pump 1 at that time.

[0043] When the first device 4 and the second device 5 are tested simultaneously under a certain working condition, the first device 4 requires a coolant flow rate of 10L / min, and the second device 5 requires a coolant flow rate of 15L / min, then the first valve 8 and the second valve 9 are both opened first, and the coolant flow rate of the main pump 1 is adjusted to 25L / min through the inverter 2, and then the coolant flow rate of the first valve 8 is controlled at 10L / min, and the coolant flow rate of the second valve 9 is controlled at 15L / min.
