Abstract

The invention relates to a liquid heat-conducting medium injection pipe and a heating device. The injection pipe is installed in a shell of a heat exchange device and provides a liquid heat-conducting medium into the shell, and a liquid outlet for the liquid heat-conducting medium to flow out is formed in the shell. The injection pipe comprises a main liquid inlet pipe and a branch pipe communicated with the main liquid inlet pipe, wherein one end of the main liquid inlet pipe is a closed end, the other end of the main liquid inlet pipe is a liquid inlet for the liquid heat-conducting medium to flow in, the closed end is close to the liquid outlet, the branch pipe is arranged at the position close to the liquid inlet of the main liquid inlet pipe, spraying holes are uniformly formed in the main liquid inlet pipe, one end of the branch pipe is a closed end, the other end of the branch pipe is communicated with the main liquid inlet pipe, and jet flow holes are formed in the pipe wall, facing the closed end of the main liquid inlet pipe, of the branch pipe. Compared with the prior art, the heat exchanger has the advantages of high heat exchange efficiency, no overheating phenomenon and the like.

Description

technical field

[0001] The invention relates to a liquid heater, in particular to a liquid heat-conducting medium injection pipe and a heating device. Background technique

[0002] In the roller temperature controller, it is necessary to heat the heat-conducting medium. The traditional heater is similar to a U-shaped tube heat exchanger. One end is filled with heating tubes, and the heat-conducting medium is passed through the shell. Since there is no baffle in the middle to interfere with the fluid, the thermal flow of the flow-guiding medium in the heater cannot be fully turbulent, and it is difficult for the heat-conducting medium to fully contact the heat exchange tube, and the medium is heated unevenly. It is also found in the actual use that there is Carbonization due to overheating of the medium. Therefore, it is not only necessary to enhance the heat exchange efficiency of the heat exchanger, but also to avoid overheating of the heating pipe. Contents of the inven...
