[0025] Figure 1 The utility model is a schematic diagram of a device for making ice water from liquid nitrogen according to an embodiment of the utility model.

[0026] like Figure 1 As shown, the utility model provides a device for making ice water with liquid nitrogen, comprising: a water container 101 for placing water at room temperature; a heat exchanger 102, arranged in the water of the water container 101, and heat exchange is performed with water by transporting liquid nitrogen in the heat exchanger 102, the heat exchanger 102 comprising an inlet pipe 103 and an outlet pipe 104; a temperature sensor 105, arranged above the water container 101 for monitoring the temperature of the water.

[0027] Specifically, the liquid nitrogen ice water making device in this embodiment can solve the problem that the test cannot be conducted if the ice maker at the test site cannot make ice. The low temperature of liquid nitrogen can be used to quickly prepare ice water to ensure that the test is carried out normally. After the liquid nitrogen is transported to the heat exchanger 102, the liquid nitrogen and water in the heat exchanger 102 are exchanged, and the low temperature of the liquid nitrogen is transferred to the normal temperature water through the heat exchanger 102, so that the temperature of the water is reduced to form an ice-water mixture. In addition, the temperature of the water is monitored by the temperature sensor 105, and the actual value of the compensation temperature can be determined, thereby improving the accuracy of the temperature measurement and the ice making effect.

[0028] In one embodiment, the test temperature of the aerospace engine needs to be based on ice water with a temperature of 0° as the temperature reference point. If the ice maker fails and cannot make ice, the device can be used to quickly prepare ice water to ensure the smooth progress of the test. When the temperature sensor 105 detects that the water temperature reaches 0°, it means that the ice water can be used for engine testing.

[0029] Among them, the liquid nitrogen ice water making device of the present application can improve the safety of ice water making, avoid the problem of splashing caused by direct mixing of liquid nitrogen and water, and has high efficiency in making ice water.

[0030] According to an embodiment of the present invention, the device for making ice water with liquid nitrogen further includes: a first pipeline 106 connected to the inlet pipe 103 for transmitting liquid nitrogen to the heat exchanger 102 .

[0031] According to an embodiment of the present invention, the device for making ice water with liquid nitrogen further includes: a second pipeline 107 connected to the outlet pipe 104 for transporting nitrogen from the heat exchanger 102 to the outside.

[0032] According to an embodiment of the present invention, the device for making ice water with liquid nitrogen further includes: a liquid nitrogen valve 108, which is arranged on the first pipeline 106 and is used to control the transmission of liquid nitrogen.

[0033] According to an embodiment of the present invention, the device for making ice water with liquid nitrogen further includes: a temperature controller 109 connected to the temperature sensor 105. When the temperature of the water reaches the set temperature, the temperature controller 109 disconnects the liquid nitrogen valve 108.

[0034] According to an embodiment of the present invention, the device for making ice water from liquid nitrogen further includes: an optical fiber, and the temperature controller 109 is connected to the temperature sensor 105 via the optical fiber.

[0035] According to an embodiment of the utility model, the device for making ice water with liquid nitrogen also includes: a sunflower radiator 110, which is arranged outside the second pipeline 107 and is used to heat the second pipeline, improve the gasification rate of liquid nitrogen, and increase the nitrogen temperature in the pipeline.

[0036] According to an embodiment of the present invention, the device for making ice water with liquid nitrogen further includes: a pneumatic vibrator 111, which is arranged on the second pipeline 107. The nitrogen in the second pipeline 107 is used to supply air to the pneumatic vibrator 111.

[0037] According to an embodiment of the present invention, the inlet pipe 103 and the outlet pipe 104 are corrugated pipes.

[0038] Specifically, liquid nitrogen is transported to the heat exchanger 102 disposed in the water container 101 to exchange heat with water, thereby reducing the water temperature. In this embodiment, a pneumatic vibrator 111 is used to vibrate the heat exchanger 102. The pneumatic vibrator 111 stirs the water around it, and the vibration causes the water disposed outside to flow, thereby making the heat exchange more uniform. The pneumatic vibrator 111 uses vaporized nitrogen as a driving force, and there is no need to prepare other driving force sources. The device is simple and practical, and while improving the heat exchange effect, it reduces the heat exchange cost. In this embodiment, the pneumatic vibrator 111 can select a vibrator of model GT4, which can rely on the vibration of nitrogen to make the heat exchanger 102 shake.

[0039] Among them, in the present application, the temperature sensor 105 can monitor the temperature of the water. For example, in the present embodiment, the temperature is set to 0°. When the set temperature is reached, the temperature controller 109 can automatically close the liquid nitrogen valve 108 on the first pipeline 106, and the operation of preparing ice water is completed, realizing full automation and unmanned management.

[0040] In this embodiment, the inlet pipe 103 and the outlet pipe 104 are made of bellows. The bellows have a certain flexibility, so that the heat exchanger 102 can be shaken more easily through the gas vibrator, thereby improving the uniformity of heat exchange and improving the heat exchange efficiency. The sunflower radiator 110 located outside the second pipeline 107 can heat the residual liquid nitrogen in the second pipeline 107, thereby increasing the nitrogen temperature in the pipeline and the liquid nitrogen gasification rate. In addition, by arranging a gas vibrator on the second pipeline, the present application can use the gasified liquid nitrogen in the second pipeline 107 to supply gas to the pneumatic vibrator 111, thereby further improving the heat exchange effect.

[0041] The above embodiments can be combined with each other and have corresponding technical effects.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
