Abstract
The utility model relates to a hot pipe electric heater composed of a hot pipe, electric heater cooling fins and a deflation valve. The electric heater is sealed and soaked in the heat conducting medium in the hot pipe, and the heat conducting medium is heated by the electric heater. The hot pipe electric heater uses electricity to heat the heat conducting medium and makes the heat conducting medium generate phase state variation under the condition of negative pressure to release heat energy outwards. The utility model has the advantages of little power consumption, high thermal utilization rate, fast heat radiation and long service life.
Description
The application relates to a kind of electric heater, especially a kind of heat pipe electric heater.
Electric heater is the basic heater element in the home electrical heater, uses very extensive.Electric heater commonly used mainly contains infrared light electric heating device and Electric heater, and the former exposes by heating, fire hazardous danger, though the latter's electric heating tube is wrapped up by heat-dissipating casing and heat-conducting medium, power consumption wastes energy greatly.
The application's purpose is to disclose a kind of rapid heat dissipation, and power consumption is little, the heat pipe electric heater that the heating wire life-span is long.
For finishing above-mentioned purpose, the technical scheme that the application adopts is to utilize the ability of transmission heat of heat pipe big, the characteristics that heat transfer temperature difference is little, design a kind of heat pipe electric heater, electric heater by the tape insulation shell, heat pipe and heat-dissipating fin are formed, and it is characterized in that described electric heater envelope is dipped in the interior heat-conducting medium of heat pipe, and the end top of heat pipe heat radiation section is provided with means of deflation.
Heat pipe is a sealed tube, and the heat-conducting medium in it is about 1/3 of inner chamber, and its complementary space is the negative pressure of vacuum chamber.When the electric heater in envelope is dipped in heat pipe is switched on, electric heater is about to the heat-conducting medium in a large amount of heat transferred heat pipes, heat-conducting medium is heated vaporization (under the condition of negative pressure, vapourizing temperature is lower than vapourizing temperature under the normal pressure), the medium steam of vaporization will rush at the radiating segment of heat pipe and discharge the latent heat of vaporization and condense into liquid, the liquid that condenses is got back to lower heating along heat pipe wall again because of gravity and is vaporized once more.Constantly dispel the heat to reach the purpose of heating by the heated liquid vaporization of heat-conducting medium, the circulation that the gas heat radiation is condensed like this to the external world.
This kind utilizes medium phase-state change heat-conducting mode in the heat pipe, and its heat transfer coefficient is very high, and thermal resistance is little, installs fin in addition outside heat pipe shell additional, makes heat transfer area increase manyfold than common electric heater, reaches aim of power saving.
Electric heater soaks in the heat-conducting medium liquid that is enclosed in the heat pipe at work all the time, thereby the operating temperature of electrothermal tube is than low many of the operating temperature of common electrical heat pipe, and the insulating barrier of electrothermal tube is difficult for aging, has prolonged the life-span of heating wire.
The application provides two most preferred embodiments.
First single tube hot pipe electric heater, it two is multitube heat pipe electric heaters, below in conjunction with the embodiment accompanying drawing this application is described in further detail.
Fig. 1 single tube hot pipe electric heater
Fig. 2 multitube heat pipe electric heater
Referring to accompanying drawing, the feature of single tube hot pipe electric heater is, heat pipe 2 is the single tube structure, and electric heater 5 envelopes are dipped in the heat-conducting medium 6 in the heat pipe, the external some heat-dissipating fins 4 of heat pipe wall, and the heat pipe top has vent valve 1 to be communicated with negative pressure of vacuum chamber 3.
The feature of multitube heat pipe electric heater is that heat pipe 2 is the multitube structure, and a plurality of heat pipes are arranged side by side, and its bottom is connected with the horizontal tube 8 of a sealing, is filling with the heat-conducting medium 6 that is connected with heat pipe in the horizontal tube, and the electric heater envelope is dipped in the interior heat-conducting medium of this horizontal tube.Vent valve 1 is all arranged at the radiating end top of each heat pipe 2, is connected outward by heat-dissipating fin 4 between the heat pipe.
Connect power supplys by power connecting column 7 during use, the rising of under condition of negative pressure, vaporizing of electric heater 5 heating heat-conducting mediums 6, this medium, the lower end is got back in the condensation of dispelling the heat then again, reaches the purpose of heating with this.Assemble when incondensable gas is arranged when the end top of heat pipe negative pressure cavity 3, open vent valve 1, incondensable gas is bled off, fastening again vent valve makes the heat pipe performance of resuming work.
Claims (3)
1, a kind of heat pipe electric heater contains electric heater, heat pipe and heat-dissipating fin, it is characterized in that described electric heater, and envelope is dipped in the interior heat-conducting medium of heat pipe, and heat-dissipating fin is external on the heat radiation wall of heat pipe, and the end top of heat pipe heat radiation section is provided with means of deflation.
2, heat pipe electric heater as claimed in claim 1 is characterized in that described heat pipe is the single tube structure.
3, heat pipe electric heater as claimed in claim 1, it is a plurality of to it is characterized in that described heat pipe has, the bottom of each heat pipe is connected with the horizontal tube of a sealing, is filling with the heat-conducting medium that is connected with heat pipe in the horizontal tube, and the electric heater envelope is dipped in the interior heat-conducting medium of this horizontal tube.
