Abstract
The utility model discloses a high-efficiency solar heat collecting vacuum tube which comprises a vacuum tube body and heat transfer water pipes; the vacuum tube body is a U-shaped double-layered glass tube; the heat transfer water pipes are distributed in the vacuum tube in a spiral shape; the outer walls of the heat transfer water pipes and the inner wall of the inner layered glass tube are adhered tightly; the water inlet and the water outlet of the heat transfer water pipes are respectively connected with a water inlet pipe and a water outlet pipe in a water tank. Because the heat transferwater pipes in the vacuum tube, the high-efficiency solar heat collecting vacuum tube prevents the water from directly contacting with the vacuum tube, and scaling and cracking in the tube; and because the heat transfer water pipes are screwed in the vacuum tube and tightly adhered with the inner wall of the vacuum tube, the heat transmission with the solar vacuum tube can be improved, and the heat efficiency of the solar vacuum tube is improved.
Description
Technical field
The utility model relates to a kind of solar water heater, relates in particular to a kind of heat collecting vacuum pipe that is used on the solar water heater.
Background technology
In the heat utilization of solar energy, key is that the radiant energy with the sun is converted to heat energy.Because solar energy relatively disperses, and must manage it is put together, so heat collector is the various key components of utilizing solar energy equipment.Solar water heater is a kind of of heat collector, it is a kind of helioplant that adds hot water, at present, the most frequently used solar water heater mainly is made of water tank that is filled with water and the vacuum tube that adds hot water, vacuum tube is inside and outside double-layer glass tube, and inside is evacuated, and inner tube outer surface is painted the coating that can absorb heat, water is heated in interior pipe, and and circulatory system of water tank formation.Also there is certain problem in this solar vacuum-tube water heater, because water directly contacts with vacuum tube, service time is of a specified duration, easily at in-tube fouling, influences endothermic effect, because of in managing water is arranged at severe cold area simultaneously, makes the vacuum tube bursting by freezing.
Summary of the invention
The purpose of this utility model is the above problem that exists at existing vacuum tube, a kind of improved high-efficiency solar heat collecting vacuum pipe is provided, by the thermal conductive water pipe is set in vacuum tube, water in the water heater is not directly contacted with vacuum tube, overcome problem at in-tube fouling and bursting by freezing in winter vacuum tube.
The purpose of this utility model is achieved through the following technical solutions, this high-efficiency solar heat collecting vacuum pipe comprises the vacuum body, the thermal conductive water pipe, described vacuum body is the double-layer glass tube of " U " type, it between described double-layer glass tube vacuum layer, described inner layer glass tube is an endothermic tube, the surface scribbles heat-sink shell, described thermal conductive water pipe's curl is distributed in the vacuum tube, described thermal conductive water pipe's outer wall closely pastes mutually with the inwall of true inner layer glass tube, to reach best heat-transfer effect, described thermal conductive water pipe's water inlet, delivery port respectively with the water inlet pipe that is positioned at water tank, outlet pipe links to each other.
The beneficial effects of the utility model: owing in vacuum tube, be provided with the thermal conductive water pipe, avoided water directly to contact with vacuum tube, in pipe, produce the problem of fouling and bursting by freezing, again because the thermal conductive water pipe is that spiral is in vacuum tube, fit tightly with the inwall of vacuum tube, can increase and solar energy vacuum tube between the heat transmission, improved the thermal efficiency of solar energy vacuum tube.
