Small-size high-efficiency electric heating device with waste heat recovery function

Abstract

The invention relates to the technical field of liquid electric heating, in particular to a small-size high-efficiency electric heating device with a waste heat recovery function. The device comprisesa plurality of electric heating tubes, the plurality of electric heating tubes communicates with each other through connecting tubes to form a liquid electric heating channel, a heat conduction shellare arranged outside the electric heating tubes in a sleeved mode, the upper ends and the lower ends of the electric heating tubes are fixed together with the heat conduction shell through fixing pieces, the heat conduction shell is integrally formed with a water inlet tube, and the water inlet tube communicates with the water inlet end of the liquid electric heating channel. According to the device, a liquid electric heating assembly can effectively reduce the size of the assembly under the same power, the occupied volume of the space is reduced, meanwhile, heat can be recycled, so that theheat efficiency is improved, the energy is saved, the environment is protected, and meanwhile, the temperature of the outer sleeve shell is kept low and the outer sleeve shell is convenient to use ina narrow space.

Description

technical field [0001] The invention relates to the technical field of liquid electric heating, in particular to a small-volume high-efficiency electric heating device with a waste heat recovery function. Background technique [0002] With the continuous advancement of science and technology, the electrical equipment involved in home life gradually tends to be miniaturized. The miniaturization of electrical equipment can reduce the space occupied by the volume. In order to make electrical equipment smaller and meet people's normal needs, electrical manufacturers will choose If the heating element with high efficiency and high power density dissipates slowly or the heat of the liquid is not absorbed in time, it will cause the heating element to burn out. At the same time, if the structural design is unreasonable, it will cause energy waste. At the same time, most of the current instant heating components are placed vertically, which limits the overall design and application s...
