Said heat pipe comprises and places the interior pipe in the cover glass tube and place the outer condenser pipe of said cover glass tube, said in pipe and the coaxial setting of condenser pipe and be tightly connected with said cover glass tube respectively;
Said heat pipe is provided with said cover glass tube is eccentric, and the downside inner headed face of said cover glass tube is provided with the mirror surface that is used to collect said heat pipe both sides light, and the light of said heat pipe both sides gathers on the said heat pipe after said mirror surface reflection.
Said mirror surface is the reflecting material that is plated on the said cover glass tube inwall; Be coated with on the periphery of pipe in said and be used for light is carried out the light-absorbing coating that selectivity absorbs, said in the light of pipe both sides after said mirror surface reflection, gather and be positioned at said pipe and deviate from the light-absorbing coating of light side.
Further, pipe and the said condenser pipe structure that is formed in one in said.
Said heat pipe is the enclosed vacuum glass tube, is filled with heat-transfer working medium in it.
The beneficial effect of the technical scheme that the utility model embodiment provides is:
1. the utility model is plated on the inside of cover glass tube with speculum, has simplified the structure of complete machine, makes the structure of thermal-collecting tube more simple;
2. through the reflecting condensation effect of built-in mirror surface, increased the effective utilization rate of light of thermal-collecting tube, the thermal-arrest ability is stronger, and temperature is higher, has avoided the drawback of external reflecting plate accumulated snow, incrustation, increase windage simultaneously again;
3. the cover glass tube of interior light-focusing type combines with heat pipe structure, realizes transmitting heat through flowing of heat-transfer working medium and phase transformation, conducts heat sooner, more efficient;
4. this heat pipe replaces metal material as heat resistant material with glass material, and cost is lower, and the realization of the process for sealing between the cover glass tube is easier.
