Preferably, the first tube wall of described heat-exchange tube is made up of metallic plate, and the thickness range of described metallic plate is 0.05-0.2mm.Adopt the metal sheet that 0.05-0.2mm is thick, the heat exchanger effectiveness of heat-exchange tube can be improved.
The utility model in use, first the first tube wall of two heat-exchange tubes be close to the pipeline that need dispel the heat and be combined to form the through hole passed for described pipeline, then making the heat-conducting medium in heat-exchange tube and the refrigerant of the pipeline that need dispel the heat flow to do coaxial reverse flow to carry out heat exchange.
The beneficial effect that the utility model brings is:
1) the utility model overcomes heat exchanger in prior art and refrigeration plant refrigerant solution matter and heat exchange heat conduction solution matter can not be carried out the shortcoming of the coaxial reverse exchange of whole process, by the first tube wall of described heat-exchange tube being close to the outer wall of described pipeline, thus the heat exchange that can realize under maximum temperature gradient, therefore the heat exchange peak value temperature difference that causes of the utility model is large, can not waste refrigeration plant and a large amount of useful work of heat exchange solution matter.
2) component key element of the present utility model is simple, existing for refrigeration plant shell and tube, casing formula condenser or evaporator heat exchanger weight minimizing more than 95-98% on year-on-year basis.
3) the utility model surrounds a closed circular by the first tube wall of two heat-exchange tubes, gapless can balancedly disperse the pressure of heat exchanger heat heat conduction solution matter, and be close to condenser of refrigeration equipment or evaporimeter refrigerant solution matter pipe surface and exchange with maximum temperature gradient and the coaxially reverse thermally conductive heat of refrigerant solution matter, thus shorten heat exchange stroke and shortening heat exchange time to peak, while avoiding the short circuit of part heat conduction solution matter, dead angle, also reduce the impact of the oxidation of heat conduction solution confrontation refrigeration plant refrigerant solution matter pipeline external surface, incrustation scale and corrosion.
The further improvement of technique scheme is: the inner side of the second tube wall of described heat-exchange tube is interval with the wave groove of multiple U-shaped along the length direction of heat-exchange tube.Like this, not only can strengthen the bulk strength of heat-exchange tube, and the heat-conducting medium in heat-exchange tube can be made to form turbulent flow, improve the efficiency of heat exchange.
The further improvement of technique scheme is: also comprise the sealing ring that two plastic materials are made, two sealing rings all fit tightly with heat exchange tube inner wall and lay respectively at the two ends of heat-exchange tube, each sealing ring is equipped with from heat-exchange tube outside through the conduit extend into after sealing circle in heat-exchange tube, and described conduit is away from forming the heat-conducting medium entrance or heat-conducting medium outlet that are used interchangeably.Like this, by sealing ring, heat-conducting medium entrance and heat-conducting medium outlet are tightly connected with heat-exchange tube, heat-conducting medium entrance and heat-conducting medium exit portion is made to become flexible structure, heat exchange solution matter not only can be prevented excessive, and the slight vibrations in the running of refrigeration plant rigid conduit can be avoided, resonance harm can not be produced because of rigid structure.
