Abstract

The utility model relates to a heat-pipe electric radiator, which is made by the principle of the gravity heat pipe. Because the heat-pipe electric radiator uses water as the working medium, and the heat-pipe electric radiator works in two strong heat-transferring states of boiling heat absorption and condensing heat release all the time, the heat-pipe electric radiator has low cost. The good insulation effect between an electric heat-pipe and a casing ensures the safety of the heat-pipe electric radiator when in use.

Description

Heat-pipe electric radiator

The utility model relates to a kind of electric heating device made from the gravity assisted heat pipe principle.

Have the electric heater of making working medium of transformer oil now, have the cost height, the shortcoming that heat exchange efficiency is low.

The purpose of this utility model is that a kind of, heat pipe electric heater that efficient high lower than above-mentioned electric heater cost will be provided.

The purpose of this utility model is achieved in that the heat exchange of heat pipe water of making according to the gravity assisted heat pipe principle cooked working medium, after the electrothermal tube energising of device in working-medium water, and the explosive evaporation and absorb a large amount of latent heats of vaporization rapidly of water on every side; Steam can be full of the inner space of heat exchange of heat pipe rapidly under the effect of pressure reduction, because the ambient temperature of heat exchange of heat pipe is low, steam can be condensed into water and discharge the latent heat of vaporization; Condensed water is subjected to thermal evaporation again in the effect decline product heat cal rod heat exchanger bottom of gravity.So constantly circulation reaches the purpose that high efficient heat exchanging heats.

The utility model is done working medium owing to water and has been used boiling heat absorption and these two heat-transfer mechanisms the strongest of condensation heat release, thereby has low cost of manufacture, the remarkable advantage that heat exchange efficiency is high.

Fig. 1 and Fig. 2 are structural representations of the present utility model.

Below in conjunction with accompanying drawing concrete structure of the present utility model is elaborated: the extremely strong heat exchange of heat pipe (1) of heat-transfer capability is that the sheet metal punching press is welded into plate shaped container, inject aquae destillata (2) from aspirating hole (7), the soldering and sealing aspirating hole (7) that is evacuated is then made.The electrothermal tube (3) that is separated with insulating heat-conductive layer (6) with a heating core (4) and metal shell (5) is made thermal source, its is installed in the aquae destillata (2) of heat exchange of heat pipe (1) lining, the steel plate shell seal welding of the two ends of metal shell (5) and heat exchange of heat pipe (1), the connector lug of heating core (4) exposes, and can be used for connecing power supply.Like this, heat exchange of heat pipe (1) has been formed heat pipe electric heater with electrothermal tube (3).

Because the heating core (4) of the used electrothermal tube (3) of the utility model and metal shell (5) insulation, thus very safe when using.

The utility model can be made the series of products of multiple overall dimensions and rated temperature by different electrothermal tube power.
