Description

A kind of electric heating heat-pipe radiator

Technical field

The utility model relates to the air heating apparatus field, relates in particular to a kind of electric heating heat-pipe radiator.

Background technology

There are a lot of defectives in the tradition hot-water heating, as: hot-water heating must guarantee that the pipe network temperature keeps more than at least 0 ℃, even the time period can not stop heat, serious waste at nobody; Hot-water heating mostly is central heating system, in the heat supply network heat waste serious, the circulation of its water need be by the circulating pump consumed power; Hot-water heating is in operation, and the radiator wall temperature is low excessively, and thermal balance, pressure balance are difficult to solve in the pipe network, have local overcooling or problems of excessive heat.Electric heater and electric radiator had appearred on the market in recent years, solved most problem that traditional hot-water heating exists, but electric heater complex structure, fragile and be not suitable for large tracts of land heating, and existing electric radiator utilizes the mode of the convection current of liquid to conduct heat, conducting heat makes the spreader surface temperature unbalanced slowly, and at high temperature its radiator cavity is very easily oxidized, makes its service life short.

Summary of the invention

The purpose of this utility model provides a kind of electric heating heat-pipe radiator, solves existing electric radiator heat transfer and makes the problem that the spreader surface temperature is unbalanced, service life is short slowly.

The technical scheme that realizes above-mentioned purpose is:

A kind of electric heating heat-pipe radiator, comprise that a plurality of bottoms are communicated with the heat pipe that constitutes heat tunnel and are arranged at the interior electrothermal tube of heat tunnel, described inside heat pipe is evacuated to higher vacuum and is filled with the heat conduction with phase change medium, the top of heat pipe and middle part are as the heat radiation chamber, the bottom of heat pipe is as heating chamber, described a plurality of heat pipe constitutes the confined space of an integral body, and described heat radiation chamber is the middle ∩ die cavity body that annular heat radiation wall is arranged, and described heat conduction with phase change medium is positioned at heating chamber.

During work, electrothermal tube energising heating, make the liquid phase-change heat-conducting medium vaporization in the heating chamber, gaseous state heat conduction with phase change medium flows to the heat radiation chamber and contacts heat radiation with the heat radiation cavity wall under pressure reduction, emit heat and be condensed into the liquid phase-change heat-conducting medium, the liquid phase-change heat-conducting medium flows back in the heating chamber along the heat radiation cavity wall by self gravitation, and so circulation endlessly.Annular heat radiation wall is arranged in the centre in heat radiation chamber, increased the surface area in heat radiation chamber, promptly increased the contact area of heat radiation chamber and outside air, more help gaseous state heat conduction with phase change medium release heat.Heat pipe charges into the heat conduction with phase change medium under the higher environment of vacuum, medium heats under subnormal ambient, has reduced the boiling point of medium, has increased the concentration of saturated vapor, has improved heat transfer rate; Phase-change material has the advantages that the latent heat of vaporization is big, the coefficient of heat conduction is high, can strengthen heat-transfer effect; A plurality of heat pipes are joined together to form independently closed circulation space, do not have heat supply network heat loss problem.

The utlity model has following beneficial effect:

1, adopts the principle of hot pipe technique, utilize the evaporation and the condensation of heat conduction with phase change medium to transmit heat, because evaporation---in the diabatic process of condensation, working fluid is in saturation state in the pipe, therefore almost be under isothermal, to transmit heat, have high thermal conductivity, good isothermal;

2, increased the surface area in heat radiation chamber, and then increased area of dissipation, the heat transfer efficiency of heat conduction with phase change medium is improved;

3, phase-change material has the advantages that the latent heat of vaporization is big, the coefficient of heat conduction is high, can strengthen heat-transfer effect, and the heat conduction with phase change medium heats under subnormal ambient, has reduced the boiling point of heat conduction with phase change medium, has increased the concentration of saturated vapor, has improved heat transfer rate;

4, the heat conduction with phase change medium leans in circulation and carry out not consumption of power under gravity;

5, a plurality of heat pipes are joined together to form independently closed circulation space, do not have heat supply network heat loss problem;

6, simple in structure, not fragile, be fit to the large tracts of land heating.
