Description

Ring type heat pipe device

Technical field: the utility model relates to and utilizes ring type heat pipe heat radiation, heating, air conditioning, waste heat recovery, and low temperature is antifreeze, especially at volume and space requirement is strict or conventional heat pipe design does not reach the occasion of requirement; Be specially a kind of ring type heat pipe device.

Background technology: at present, known heat pipe structure is to be made of a metal tube, it has made full use of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, is delivered to rapidly outside the thermal source through the heat of heat pipe with thermal objects, and its capacity of heat transmission surpasses the capacity of heat transmission of any known metal.Known heat pipe is made up of shell, imbibition core and end cap.Inside heat pipe is to be pumped into negative pressure state, charges into suitable liquid, and this boiling point of liquid is low, easily volatilization.Tube wall has the imbibition core, and it is made of the capillary porous material.Heat pipe is an evaporation ends for one section, other one section is condensation end, when one section of heat pipe is heated, liquid in the capillary evaporates rapidly, and steam flows to an other end under small pressure differential, and discharges heat, regelation becomes liquid, liquid flows back to evaporator section along porous material by the effect of capillary force again, and so circulation is more than, and heat reaches an other end by heat pipe one end.This circulation is carried out fast, and heat can be come by conduction continuously.But conventional heat pipe is because structure limits, and evaporation ends must separate with condensation end, and, also need be around heat pipe when gas exchanges around sheet to increase efficient, like this in some specific occasion, conventional heat pipe constitutes the bulky of product, therefore heaviness is unfavorable for the popularization and application of heat pipe.

Summary of the invention: in order to overcome existing heat pipe in the deficiency of installing and using, it is a kind of simple in structure, with low cost that the utility model provides, also have two exchanges of internal diameter and external diameter interface, can form the ring type heat pipe device of exchange radiating end inside and outside the heat pipe.The purpose of this utility model is achieved in that it comprises internal diameter tube wall (1), external diameter tube wall (2), external diameter pipe vacuum chamber (3), internal diameter tube chamber (4).An internal diameter tube wall (1) is arranged in the external diameter tube wall (2), form external diameter pipe vacuum chamber (3) between external diameter tube wall (2) and the internal diameter tube wall (1), the medium fill orifice (5) of bleeding on an end of external diameter tube wall (2) has vacuum suction medium fill orifice (7) on the end of internal diameter tube wall (1).In external diameter pipe vacuum chamber (3), there is the external diameter plumber to make medium (6).The beneficial effects of the utility model are, the appearance of ring type heat pipe, the application popularization that has improved heat pipe greatly, ring type heat pipe is applied to every field such as waste heat recovery, air conditioning, vehicle exhaust Waste Heat Recovery because of the superior ring type heat pipe that makes in its design, the system bulk that ring type heat pipe constitutes is little, reduce the place and take, reduce weight metal, increase operating efficiency, toggle speed is fast, recovering effect is good, at the different medium of its work intra-bladder instillation, can be applied to all temps occasion.

Description of drawings: Fig. 1 is a structural principle schematic diagram of the present utility model; Fig. 2 (a) is a shape tube side structure principle schematic of the present utility model; Fig. 2 (b) is a normal type pipe side structure principle schematic of the present utility model; Fig. 3 is a cross-section structure principle schematic of the present utility model; Fig. 4 is the cross-section structure principle schematic of the utility model vacuum suction medium fill orifice.

The specific embodiment: an internal diameter tube wall (1) is arranged in the external diameter tube wall (2), form external diameter pipe vacuum chamber (3) between external diameter tube wall (2) and the internal diameter tube wall (1), the medium fill orifice (5) of bleeding on an end of external diameter tube wall (2) has vacuum suction medium fill orifice (7) on the end of internal diameter tube wall (1).In external diameter pipe vacuum chamber (3), there is the external diameter plumber to make medium (6).Ring type heat pipe is by the internal diameter tube wall, the external diameter tube wall, external diameter pipe vacuum chamber constitutes an independently conventional hot-pipe system, form (work hot junction gravity assisted heat pipe does not below need to install the imbibition core) comprising evaporation ends, imbibition core, condensation end, with be pumped into 1.3 in the pipe * fill with an amount of hydraulic fluid after the negative pressure of (10 negative 1---10 negative 4) Pa, make to be sealed after being full of liquid in the imbibition core capillary porous material of being close to inside pipe wall.An end of pipe is evaporator section (bringing-up section) when using as conventional heat pipe, and the other end is condensation segment (cooling section), and inwall and outer arm carry out heat exchange evaporative condenser end each other when using as ring type heat pipe.So circulation is not own, and heat-shift is transmitted to outer wall or opposite by the inwall of heat pipe.In traditional application, the conventional heat pipe end socket can be pressed in the two ends of internal diameter tube wall 1, increase internal diameter tube vacuum suction medium fill orifice, at high temperature inject the phase transformation storage medium that phase transition temperature is fit to external diameter pipe vacuum chamber operating temperature in the internal diameter tube chamber, this ring type heat pipe possesses hot memory function, during ring type heat pipe work, by internal diameter tube wall 1, the external diameter tube wall, external diameter pipe vacuum chamber constitutes an independently conventional hot-pipe system and constantly heats up, its waste heat supply temperature constantly gives the internal diameter tube wall 1 heating, be positioned over the continuous storing heat of phase change memory body in the internal diameter tube chamber, after external environment heat was withdrawn, the phase change memory body in the internal diameter tube chamber constantly dispelled the heat, ring type heat pipe also in work, is lower than the working media evaporating temperature until phase change memory body temperature degree and just quits work.

The conventional heat pipe end socket is pressed at two ends with the internal diameter tube wall of the present utility model, increase internal diameter tube vacuum suction medium fill orifice, inject the phase transformation storage medium that phase transition temperature is fit to external diameter pipe vacuum chamber operating temperature in the internal diameter tube chamber, this ring type heat pipe possesses hot memory function.
