Problems solved by technology
However, the inventors found that when stagnation occurs in the tank or the water flow rate slows down, the liquid in the tank will quickly absorb heat and boil, resulting in high pressure in the tank, and the water will be accompanied by a large amount of steam, which is prone to injury

Embodiment Construction
[0041] The following is attached Figure 1-6 , to further describe this application in detail.
[0042] The embodiment of the present application discloses a liquid heat exchange system in a tank with a cermet heating element. refer to Figure 5 , the liquid heat exchange system in the tank includes a housing 1 with an inner flow chamber 10, a liquid temperature sensor 2 for detecting the temperature of the liquid in the inner flow chamber 10, and a cermet heating element 3 with a rated power.
[0043] The casing 1 is made of ceramic material, and its shape can be square, cylindrical or other shapes. In this embodiment, the casing 1 is cylindrical as a whole and arranged vertically. The bottom end surface of the housing 1 is provided with a through-hole 18 through which the cermet heating element 3 passes. In this embodiment, the through-hole 18 is a round hole, and the through-hole 18 is coaxial with the housing 1 set up.
[0044] The cermet heating element 3 includes a h...

This application relates to a liquid heat exchange system in a gallbladder with a cermet heating element, which includes a housing, a liquid temperature sensor and a cermet heating element. The housing is provided with an inner flow chamber for the liquid to pass through. The liquid heating section, the hot liquid output section and the gasification buffer section are set continuously from low to high. The cermet heating element penetrates into the shell and runs through the liquid heating section. The temperature of the liquid in the section increases continuously from low to high, and the temperature of the liquid in the boiling vaporization section is at the boiling point. The length of the vaporization section is positively correlated, the shell is provided with a liquid inlet at the bottom of the temperature rising section, the shell is provided with a liquid outlet at the hot liquid output section, and the liquid temperature sensor is located in the vaporization buffer section. The application has the effect of avoiding the phenomenon of high pressure in the gallbladder or dry burning of the heating element caused by rapid evaporation of the liquid in the gallbladder.
Description
technical field [0001] The application relates to the field of fast heaters, in particular to a liquid heat exchange system in a tank with a cermet heating element. Background technique [0002] In the existing liquid heat exchanger, the heating elements in it are divided into two types: metal and non-metal. The metal heating element is generally set inside or outside the liner. When the metal heating element is set inside the liner, it will easily deposit scale during long-term use. A large amount of scale will greatly reduce the heat transfer efficiency of the heating element and cause overheating damage. . If the heating element is arranged outside the gallbladder, a part of the heating element will be in direct contact with the air, which will cause a part of heat energy to disperse into the air, and the energy utilization rate will be relatively low. The non-metal heating element is generally arranged outside the tank. Similarly, the energy utilization rate is relativ...
