Embodiment 1

[0035] This example of a heater for cryogenic fluids, such as figure 1As shown, it includes a heating cylinder 1, a heating cylinder end cap 2, a liquid outlet pipe 3, a liquid inlet pipe 4, a sleeve pipe 6, a support plate 5 and a heating layer 7; the heating cylinder 1 is a long and thin cylindrical cylinder with an open end, heating The cylinder end cover 2 is fixed on the opening of the heating cylinder 1, and the heating cylinder 1 is sealed; the liquid outlet pipe 3 and the liquid inlet pipe 4 are fixed on the heating cylinder end cap 2, penetrate the heating cylinder end cover 2 and extend into the heating cylinder 1 In addition, the liquid inlet pipe 4 extends into the position where the middle and lower part of the heating cylinder 1 is close to the bottom end, and the liquid outlet pipe 3 extends into the position where the middle and upper part of the heating cylinder 1 is close to the open end. The liquid outlet pipe 3 and the liquid inlet pipe 4 The heating layer ...

Embodiment 2

[0039] In this example, the low-temperature fluid heater of Embodiment 1 is applied to a low-temperature fluid circulation system for simulating thermal shock, and the low-temperature fluid circulation system for simulating thermal shock in this example, such as image 3 As shown, including cold source 11, power element 12, thermal shock simulation element 13 and end user 14, the cold source 11, power element 12, thermal shock simulation element 13 and end user 14 form a closed low-temperature fluid circulation system, and the low-temperature fluid Driven by the power element 12, it circulates in the circulation system. Among them, the thermal shock simulation element 13 is the low-temperature fluid heater of the first embodiment, which is used to provide heat to the low-temperature fluid to simulate the thermal shock generated by the end user 14 under working conditions; the cold source 11 provides cooling capacity for the circulation system.

Abstract

The application discloses a heater for cryogenic fluid and its application. The heater used for cryogenic fluid in this application includes a heating cylinder, a heating cylinder end cover, a liquid outlet pipe, a liquid inlet pipe, a sleeve and a heating layer; the heating cylinder is a cylindrical cylinder with one end open, and the heating cylinder end cover is fixed to the heating cylinder Seal the opening; the liquid outlet pipe and the liquid inlet pipe are fixed on the end cover of the heating cylinder, penetrate the end cover of the heating cylinder and extend into the heating cylinder, the liquid inlet pipe extends into the position near the bottom of the heating cylinder, and the liquid outlet pipe extends into the heating cylinder The heating layer is evenly wrapped on the outer surface of the heating cylinder, and the heating cylinder is sealed and fixed in the sleeve. There is a gap between the heating layer and the sleeve. When in use, the gap is a vacuum environment. The heater of the present application has a compact structure, small size and light weight, flexible installation, safety and reliability, high-efficiency heat insulation, can accurately calculate and control the heating power of the low-temperature fluid, and solves the problems of the existing low-temperature fluid heater with complex structure and bulky volume. Improved heating efficiency.

Description

technical field [0001] The present application relates to the field of low-temperature fluid heating, in particular to a heater for low-temperature fluid and its application. Background technique [0002] Cryogenic fluids generally refer to fluids whose boiling point is lower than 120 Kelvin (abbreviated as K), that is, about minus 153 degrees Celsius. Cryogenic fluid heating is different from conventional fluid heating. First, the heating amount must be strictly controlled. The heat provided by the heater and the heat absorbed by the low-temperature fluid must be accurately calculated; second, the heating must be uniform, otherwise it will easily occur. Cryogenic fluid vaporizes, creating a risk of overpressure. [0003] In the Chinese patent with the notification number CN 204963158U, a conventional liquid heater is described. The liquid flows through the liquid inlet pipe and the liquid outlet pipe connected to both ends of the heater box, and the heating belt is detacha...
