Description

Technical Field

[0001] The utility model relates to the technical field of thermal shock testing, in particular to a temperature control device for rapid thermal shock testing. Background Art

[0002] Thermal shock tester is an essential test equipment in the fields of aviation, automobile, home appliance, scientific research, etc. It is used to evaluate and determine the products of electrical, electronic, automotive electrical appliances, materials, etc. Thermal shock tester is used to test the degree to which composite materials and material structures can withstand continuous extremely high and low temperatures in an instant, that is, to test the chemical changes or physical damage caused by thermal expansion and contraction in the shortest time.

[0003] Patent No. CN209841590U proposes a temperature control device for rapid hot and cold shock testing, which includes a return pipe, an outlet pipe, a hot water tank, a cold water tank, a variable frequency pump arranged on the outlet pipe, an electric heater arranged in the hot water tank, a circulating pump and an evaporator forming a circulation loop with the cold water tank, and a refrigeration system for cooling the water in the cold water tank at the evaporator. A first proportional regulating valve is arranged at one end of the return pipe and is divided into two paths to flow back to the hot water tank and the cold water tank respectively. A pipe is arranged at the bottom of the hot water tank and the cold water tank and is respectively connected to the two input interfaces of a second proportional regulating valve and then converged into the outlet pipe. The utility model device has high integration, small size, and can quickly mix and output the target temperature in proportion.

[0004] There are still some defects in the above patent. For example, when the water that has undergone heat exchange flows back to the hot water tank and the cold water tank, it will come into contact with the water in the hot water tank and the cold water tank again. Due to the lack of a mixing mechanism, there is a temperature deviation between the water bodies, which can easily cause uneven water temperature. In this way, when using water heat exchange for temperature control, the temperature of the water body is difficult to control stably, which reduces the temperature control effect. Therefore, we need to propose a temperature control device for rapid hot and cold shock testing. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 The utility model provides a technical solution: a temperature control device for rapid hot and cold shock testing, comprising a base 1, with water tanks 2 respectively arranged on both sides of the top of the base 1; the water tanks 2 include a cold water tank for storing cold water and a hot water tank for storing hot water.

[0026] Furthermore, temperature control components for heating and cooling the water temperature are respectively installed on the rear side of the top of the base 1, and the temperature control components are connected to one side of the water tank 2; the temperature control components include a thermostat 6 and a pump 7, the pumping end of the pump 7 is connected to the drainage end of the thermostat 6, the drainage end of the pump 7 is connected to a first pipe body 8, and the end of the first pipe body 8 away from the pump 7 is connected to the upper part of the interior of the second cavity 5, and the thermostat 6 includes a water heater for heating the water body and a water cooler for cooling the water body.

[0027] Specifically, the injection end of the thermostat 6 is connected to a second tube body 9, and one end of the second tube body 9 away from the thermostat 6 is connected to the lower part of the first cavity 4. The water in the cold water tank or the hot water tank enters the corresponding water heater or water cooler through the second tube body 9, and the water is temperature-controlled accordingly through the water heater and the water cooler.

[0028] Furthermore, a thermal insulation board 3 is installed inside the water tank 2, and a first cavity 4 and a second cavity 5 are formed inside the water tank 2 through the thermal insulation board 3. The mixing assembly is located inside the first cavity 4. After the water heater and the water cooler adjust the temperature of the water, after the water temperature reaches the preset temperature, the pump 7 is started, and the pump 7 transports the water in the water heater and the water cooler to the first pipe body 8, and then enters the second cavity 5 through the first pipe body 8 for storage and standby use.

[0029] It is worth noting that: a third tube body 10 is disposed above one side of the water storage tank 2, and one end of the third tube body 10 is connected to the interior of the first cavity 4. A fourth tube body 11 is disposed below one side of the water storage tank 2, and one end of the fourth tube body 11 is connected to the interior of the second cavity 5. By providing the third tube body 10, the water after the heat exchange is completed can enter the first cavity 4 in the water storage tank 2 again through the third tube body 10, thereby achieving the purpose of circulating heat exchange.

[0030] In addition, an electric control valve 12 is installed on the surface of the fourth tube body 11, and a thermometer 13 is installed on the outside of the water tank 2. The temperature measuring end of the thermometer 13 extends to the inside of the water tank 2.

After the temperature of the water in the second cavity 5 reaches the discharge standard, the thermometer 13 transmits the temperature signal to the controller 14, and the controller 14 controls the electric control valve 12 to open, and the water in the second cavity 5 is discharged through the fourth tube body 11 and enters the inside of the hot and cold shock device, and the temperature of the test piece and the test environment is controlled by heat exchange.

[0031] The water after heat exchange flows back to the first cavity 4 through the third tube 10, and then flows into the temperature controller 6 through the second tube 9 again, and is heated and cooled accordingly, thereby achieving the purpose of cyclic heat exchange.

The mixing assembly includes a rotating shaft 16 arranged inside the first cavity 4, and stirring blades 17 are equidistantly installed on the surface of the rotating shaft 16. The top of the rotating shaft 16 rotates and extends to the outside of the water tank 2 and is connected to a motor 18 through a coupling, and the outside of the motor 18 is connected to the surface of the water tank 2. By starting the motor 18, the power output end of the motor 18 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the stirring blade 17 to rotate while the rotating shaft 16 rotates. While the stirring blade 17 rotates, the original water in the first cavity 4 and the water subsequently injected into the third tube 10 are stirred and blended, so that the temperature of the water remains uniform, and the effect of subsequent temperature adjustment is improved.
