Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange of electric boilers, and specifically relates to a heat exchange device of a heat pump coupled with an electric boiler. Background Art

[0002] An electric boiler, also known as an electric heating boiler or an electrothermal boiler, as the name implies, uses electricity as an energy source and converts it into heat energy. Then, through the conversion of the boiler, it outputs steam, high-temperature water or organic heat carriers with a certain amount of heat energy.

[0003] However, the existing devices have the following problems:

[0004] The existing devices mainly directly heat the heating wire and the heat exchange tube, so that during the heating process of the heating wire, the heat exchange tube is in direct contact with the heating wire, resulting in too fast temperature rise of the heat exchange tube and affecting the service life of the heat exchange tube.

[0005] At the same time, in some devices, when the power of the heating wire is too high, the pressure of the heat exchange tube becomes large, and the pressure of the heat exchange tube cannot be regulated, which easily leads to too large pressure of the heat exchange tube and causes the heat exchange tube to break.

[0006] Therefore, in order to solve the above problems, a heat exchange device of a heat pump coupled with an electric boiler is proposed. Summary of the Invention

[0007] The purpose of the utility model is to provide a heat exchange device of a heat pump coupled with an electric boiler to solve the problem of heat exchange of the electric boiler in the existing technology mentioned in the above background art.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model drives the circulation pipe to be heated by heat transfer oil. By starting the rotary pump, the rotary pump drives the rotary vane to circulate the liquid inside the circulation pipe and discharge the heat. When the pressure inside the circulation pipe is too high, the pressure pushes the pressure relief column, and the pressure relief column pushes the pressure relief spring to relieve the pressure. When the pressure is too high, the pressure relief column pushes the detection ball, and the detection ball drives the connecting switch. By closing the wire, the display bulb, the magnetic switch and the connecting speaker are started to warn the staff. By starting the magnetic switch to close the rotary pump, the pressure is relieved.

[0016] By fixedly connecting a circulation housing below the circulation pipe, fixedly connecting a rotary pump to the outer side of the circulation housing, fixedly connecting a rotary vane to the outer side of the rotary pump, fixedly connecting a discharge pipe to the outer side of the circulation housing, fixedly connecting an input pipe below the circulation pipe, and fixedly connecting an input port inside the heating box, the present utility model can isolate the heat exchange pipe from the heating wire during the heating process of the heating wire, thereby improving the service life of the heat exchange pipe.
