Description

Glassy metal sealing-in formula Horizontal heat pipe

Technical field

The utility model belongs to technical field of solar water heaters, relates to a kind of glassy metal sealing-in formula Horizontal heat pipe.

Background technology

At present, solar electric water heater has been widely used in residential building, and its principle is: sunshine sees through glass tube, is radiated on absorber plate, and the solar energy selective absorbing film of high-absorbility is converted into heat energy by solar radiant energy.The heat that absorber plate absorbs is rapidly by a small amount of working medium vaporization in heat pipe, for guaranteeing that the working medium of vaporization rises to rapidly condensation end, during vacuum tube work and the inclination angle on ground should be greater than 15 degree, the working medium being vaporized rises to condensation end of heat pipe and emits after the latent heat of vaporization to heated working medium (water or air), be condensed into liquid, at the dirty product heat cal rod evaporation ends of Action of Gravity Field, utilize the vapour-liquid phase of a small amount of working medium in heat pipe to become cyclic process, continuously the solar radiant energy of absorption is delivered to condensation end heating working medium.

Existing heat pipe is mostly gravity assisted heat pipe, must have certain angle when mounted, in installing and using process, limited to, cannot with building perfect adaptation, realize integrated.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of glassy metal sealing-in formula Horizontal heat pipe simple in structure, ingenious, rational is provided, and this heat pipe can level be installed, and then attractive in appearance and well behaved heat collector is provided.

The technical scheme providing according to the utility model: a kind of glassy metal sealing-in formula Horizontal heat pipe, be characterised in that: comprise heat transfer tube core, casting coping, outer glass pipe, heat absorption aluminium flake, wherein said outer glass pipe one end is openend, one end is blind end, described openend capping has casting coping, in outer glass pipe inner chamber, be fixedly installed circular heat absorption aluminium flake, heat transfer tube core stretches into the endoporus of heat absorption aluminium flake from the openend of outer glass pipe; Described heat transfer tube core front portion is condensation end, has ring-type gear cap on the outer circumference surface of core body rear portion, and described ring-type gear cap is arranged on casting coping.

As further improvement of the utility model, the center of described outer glass pipe blind end has a columned projection.

As further improvement of the utility model, described heat-transfer pipe in-core wall has the groove of uniform setting.

As further improvement of the utility model, described heat absorption aluminium flake laminating is arranged on described outer glass pipe inwall, and described heat absorption aluminium flake extends to blind end from the openend of outer glass pipe.

Compared with prior art, advantage is the utility model: the utility model glass sealing formula Horizontal heat pipe collecting efficiency is high, and long service life is influenced by ambient temperature little, also can guarantee higher collecting efficiency in the winter time; Adopt metal sealing hot pipe type vacuum heat collection pipe, thermal capacitance is little, startup is fast, and superconductive medium conducts heat, in glass tube, do not leak water, effective anti-sealing fouling and freezing, thermal-collecting tube condensation head does not directly contact with water, not impact system operation while changing thermal-collecting tube, easy to maintenance, heat collecting module water resistance is little, and pump energy consumption is low, bearing operation, operating pressure is 0.6Mpa, can level install, and not limited by setting angle.
