Description

Technical Field

[0001] This utility model relates to the field of heat pipe thermostatic bath technology, specifically a heat pipe thermostatic bath for calibrating short temperature sensors. Background Technology

[0002] The heat pipe constant temperature bath for short temperature sensor calibration is a special heat pipe temperature control device designed to provide a high-precision and high-stability temperature environment for small temperature sensors to achieve their calibration function.

[0003] Existing patent document CN101608956A discloses a heat pipe constant temperature bath for calibrating short temperature sensors. It includes a heat pipe condenser, a heat pipe core, and a sensor insertion tube disposed within the heat pipe core. The heat pipe condenser is positioned higher than the upper end of the heat pipe core. The key feature is that the upper end of the heat pipe core is connected to the lower end of the heat pipe condenser via a pipe. Compared to the previous bent-pipe connection structure (connected to the middle or upper part of the heat pipe condenser), this improved structure increases the heat pipe's transmission power, improves its dynamic performance, reduces the temperature difference between the area near the upper end face of the test insertion hole and the constant temperature zone of the heat pipe, and improves the load-bearing capacity of this area. Temperature field test results also show that the structural improvement significantly reduces the temperature difference above each sensor test hole, resulting in a more uniform temperature distribution, which is more conducive to the calibration / testing of short sensors.

[0004] However, while existing short-type temperature sensor calibration heat pipe thermostat baths can calibrate temperature sensors, they typically require heating the liquid during calibration. The temperature sensor monitors the temperature rise of the liquid to check if the sensor temperature matches the liquid temperature. However, when the liquid temperature in the heat pipe thermostat bath reaches a certain level and low-temperature testing is required, the liquid needs to be cooled before low-temperature calibration can be performed. Since it is difficult to circulate the liquid in the heat pipe thermostat bath, the calibration efficiency is low. To address this issue, we propose a short-type temperature sensor calibration heat pipe thermostat bath. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a short-type temperature sensor calibration heat pipe thermostatic bath to solve the problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a heat pipe constant temperature bath for calibrating a short temperature sensor, comprising a constant temperature bath body, a pump and a temperature monitor installed inside the constant temperature bath body, a pipe threaded to the outside of the pump, a liquid delivery pipe and a water delivery pipe threaded to one end of the pipe, a refrigeration box bolted to one side of the constant temperature bath body, a heat dissipation groove installed on one side of the refrigeration box, a liquid pump, a semiconductor cooling chip and a cooling fan installed inside the refrigeration box, a liquid pump threaded to the outside of the liquid pump and a liquid extraction pipe, and a water storage tank bolted to the other side of the constant temperature bath body, a water extraction pipe installed inside the water storage tank and a water pump threaded to the outside of the water extraction pipe.

[0007] Preferably, a sealing cover is bolted to the top of the constant temperature bath body, a calibration tube passes through the top of the sealing cover, and a heating tube is installed on the outside of the calibration tube.

[0008] Preferably, a control panel is bolted to the front of the constant temperature bath body, and a display screen and a control switch are respectively installed on the front of the control panel.

[0009] Preferably, the bottom of the constant temperature bath body is bolted to a base, and the four corners of the bottom of the base are threaded with support legs.

[0010] Preferably, an infusion valve is threaded onto the outer side of the infusion tube, and one end of the infusion tube is threaded onto the refrigeration box.

[0011] Preferably, a water supply valve is threadedly connected to the outer side of the water supply pipe, and one end of the water supply pipe is threadedly connected to the water storage tank.

[0012] Preferably, the thermostatic bath body is made of metal material and the outer surface of the thermostatic bath body is smooth.

[0013] (III) Beneficial Effects This invention provides a heat pipe constant temperature bath for calibrating short temperature sensors, which has the following advantages: (1) This type of short-type temperature sensor calibration heat pipe thermostatic bath, through the setting of a cooling box and a water storage tank, when using the temperature sensor calibration heat pipe thermostatic bath, the operator places the temperature sensor in the calibration tube and connects it to the control panel. Then the heating tube emits heat to heat the water, at which time the water temperature rises. At the same time, the temperature monitor monitors the water temperature, and the temperature is applied to the calibration tube. The temperature sensor in the calibration tube can then monitor the water temperature to obtain whether the temperature monitored by the temperature sensor is consistent with the temperature monitored by the temperature monitor. When it is necessary to perform low-temperature calibration of the temperature sensor, the heating tube stops running. At this time, the water pump draws hot water from the inside of the thermostatic bath through the water pumping pipe. The hot water enters the water storage tank. When the hot water is exhausted, the pump runs, and the infusion valve opens. The infusion pipe draws water from the cooling box into the thermostatic bath. Inside the main body of the heat pipe thermostat, the thermoelectric cooler continuously operates during operation. The cooling surface of the thermoelectric cooler cools the water in the cooling chamber, keeping it at a low temperature. The same temperature monitor monitors the water temperature. The cold water cools the calibration tube, allowing the temperature sensor to monitor at a low temperature, thus verifying whether the temperature monitored by the temperature sensor matches the temperature monitored by the temperature monitor. When high-temperature monitoring is required, the pump draws low-temperature water through the pumping pipe and stores it in the cooling chamber. Then, the pump runs and draws water through the water supply pipe. At the same time, the water supply valve opens, and hot water in the storage tank flows into the main body of the thermostat, allowing the heat pipe thermostat to circulate and alternate between hot and cold liquids. This enables the heat pipe thermostat to quickly perform high-temperature and low-temperature alternation operations, thus improving the calibration efficiency of the heat pipe thermostat.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a heat pipe constant temperature bath for calibrating a short temperature sensor, including a constant temperature bath body 1. A pump 22 and a temperature monitor 24 are installed inside the constant temperature bath body 1. A pipe 23 is threaded to the outside of the pump 22. One end of the pipe 23 is threaded to a liquid delivery pipe 15 and a water delivery pipe 20. A refrigeration box 9 is bolted to one side of the constant temperature bath body 1. A heat dissipation groove 10 is installed on one side of the refrigeration box 9. A liquid pump 12, a semiconductor cooling chip 13, and a cooling fan 14 are installed inside the refrigeration box 9. A liquid pump 11 is threaded to the outside of the liquid pump 12. A water storage tank 17 is bolted to the other side of the constant temperature bath body 1. A water pump 18 is installed inside the water storage tank 17. A water pump 19 is threaded to the outside of the water pump 18.

[0018] Furthermore, a sealing cover 2 is bolted to the top of the constant temperature bath body 1, and a calibration tube 3 passes through the top of the sealing cover 2. A heating tube 301 is installed on the outside of the calibration tube 3. Heat can be emitted through the heating tube 301, so that the heating tube 301 can heat the water, thereby performing temperature sensor calibration.

[0019] Furthermore, a control panel 4 is bolted to the front of the constant temperature bath body 1. The control panel 4 has a display screen 5 and a control switch 6 installed on its front, making it convenient for staff to operate.

[0020] Furthermore, the bottom of the constant temperature bath body 1 is bolted to a base 7, and the four corners of the bottom of the base 7 are threaded with support legs 8. The support legs 8 make the constant temperature bath more stable and less prone to shaking.

[0021] Furthermore, an infusion valve 16 is threaded onto the outer side of the infusion tube 15, and one end of the infusion tube 15 is threaded into the refrigeration unit 9. The infusion valve 16 can be used to open and close the infusion tube 15.

[0022] Furthermore, a water supply valve 21 is threadedly connected to the outside of the water supply pipe 20. One end of the water supply pipe 20 is threadedly connected to the water storage tank 17. The water supply valve 21 can be used to open and close the water supply pipe 20.

[0023] Furthermore, the thermostatic bath body 1 is made of metal material and has a smooth outer surface, making it more robust and durable and less prone to damage.

[0024] Working Principle: After installation, first check the installation, fixation, and safety precautions of this utility model. When using the constant temperature bath for temperature sensor calibration, the operator places the temperature sensor inside the calibration tube 3 and connects it to the control panel 4. Then, the heating tube 301 emits heat to heat the water, causing the water temperature to rise. Simultaneously, the temperature monitor 24 monitors the water temperature, and the temperature is applied to the calibration tube 3. The temperature sensor inside the calibration tube 3 can then monitor the water temperature, determining whether the temperature monitored by the temperature sensor matches the temperature monitored by the temperature monitor 24. When low-temperature calibration of the temperature sensor is required, the heating tube 301 stops operating. At this time, the water pump 19 draws hot water from inside the constant temperature bath body 1 through the water pipe 18, and the hot water enters the water storage tank 17. When the hot water is completely drawn out, the pump 22 starts running, and the infusion valve 16 opens, allowing the infusion pipe 15 to draw... Water from the cooling chamber 9 enters the body of the constant temperature bath 1. During the operation of the heat pipe constant temperature bath, the semiconductor cooling chip 13 continuously operates, and the cooling surface of the semiconductor cooling chip 13 cools the water in the cooling chamber 9, keeping the water in the cooling chamber 9 at a low temperature. The temperature monitor 24 monitors the water temperature. The cold water cools the calibration tube 3, allowing the temperature sensor to monitor at a low temperature, thus determining whether the temperature monitored by the temperature sensor is consistent with the temperature monitored by the temperature monitor 24. When high-temperature monitoring is required, the liquid pump 12 draws low-temperature water through the liquid pumping pipe 11 and stores it in the cooling chamber 9. Then, the pump 22 runs and draws water through the water supply pipe 20. At the same time, the water supply valve 21 opens, and the hot water in the water storage tank 17 flows into the body of the constant temperature bath 1. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
