Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric heaters, in particular to a tubular fluid electric heater. Background Art
[0002] A tubular fluid electric heater is a device that uses electric heating elements to heat fluids. It consists of many straight tubes through which the fluid (such as water, oil, air, etc.) is transported to the heater. Inside the heater, the electric heating elements convert electrical energy into thermal energy, causing the fluid to heat up. The heater is designed so that each tube can be heated evenly, thereby achieving uniform heating of the entire fluid.
[0003] The existing patent authorization number is: CN214250155U, which discloses a tubular fluid electric heater, including a junction box, an electric heating element, a connecting sleeve, a heat sink, a tube sheet, an electric heater shell, a baffle and a temperature measuring element. The electric heater shell is a semi-enclosed container with an opening at one end. The interior of the electric heater shell is provided with a plurality of electric heating elements and evenly distributed baffles. The end of the electric heater shell is provided with a tube sheet that seals the open end thereof. The electric heating element is U-shaped and its open end extends to the interior of the junction box after passing through the baffle and the tube sheet. The heater heats a large flow of fluid to the temperature required by the process. After analyzing the above electric heating, it is found that the main way to uniformly heat the internal heating medium is by shortening the heat transfer path and setting a baffle in the heater. However, the above method lacks effective driving ability for the flow of the heating medium in the heater, that is, the fluidity of the medium is insufficient. In most cases, the liquid is transferred only within a certain area thereof, resulting in a position far away from the heating component, which is always heated slowly, affecting the overall heating uniformity.
[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes a shell-and-tube fluid electric heater. Utility Model Content

A circle of stirring component boxes are installed at intervals on the circumferential outer walls on the front and rear sides of the heater shell. A stirring component directly in contact with the heating medium inside the heater shell is arranged on the inner side of the stirring component box. The stirring component performs circular stirring on the heating medium inside the heater shell, and a transmission part is connected to the top of the stirring component. A group of main driving parts are connected and rotated together between the transmission parts on both sides, that is, under the operation of the active part, the transmission parts on both sides are driven to control the operation of the corresponding stirring components, thereby stirring multiple positions inside the heater shell, thereby fully improving the heating speed of the heating medium.
