Phase change type heat accumulation electric heater

Abstract

The invention relates to the technical field of electric heating, in particular to a phase change type heat accumulation electric heater. The electric heater comprises a housing, wherein phase change heat accumulation modules are mounted on both sides of an inner cavity of the housing; a heat dissipation channel is formed between the two phase change heat accumulation modules; a plurality of flat heat-conducting aluminum pipes are mounted on the side, which is close to the corresponding heat dissipation channel, of each of the two phase change heat accumulation modules at equal intervals; a heating device is arranged at the bottom of the inner cavity of the housing; the heating device comprises a heating pipe and a metal rack; the metal rack is located between the two phase change heat accumulation modules and is in contact connection with the heating pipe; heat dissipation holes are formed in the upper end of the housing; the heat dissipation holes communicate with the heat dissipation channel; and a power interface electrically connected with the heating pipe is arranged on the outer side of the housing. By adopting phase change type heat accumulation instead of heat accumulation bricks, the electric heater achieves high heat accumulation capacity, a lightweight design is realized, and the problem that heating cannot be performed at once after the electric heater is started is solved; and with the design of heating supplemented by heat accumulation, the total power of the electric heater is low.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a phase-change heat storage electric heater. Background technique [0002] At present, the vast majority of heat storage electric heaters on the market use heat storage bricks to store heat. The temperature rises to about 700 degrees and continues to dissipate heat. The existing problems are that the products dissipate heat slowly at the beginning, the heat storage effect is poor, and strong convection cannot be formed. , the heating part is easy to be damaged due to continuous high temperature, the product is bulky, the heat dissipation is uneven, the heat dissipation duration is short, and the ideal effect cannot be achieved, and the product power is relatively large. For this reason, we have introduced a phase change heat storage electric heater. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art...
