Abstract
The utility model provides a heat pipe collector with a compound insulating layer, comprising a frame, a vacuum tube arranged on the frame, a collecting tank arranged on one end of the frame, a water holding tube arranged in the collecting tank, a glass wool layer covering the outer side of the water holding tube, an aluminum foil layer covering the glass wool layer, and a polyurethane layer covering the aluminum foil layer. The utility has the advantages that the compound insulating layer adopted in the heat collector improves the integral thermal insulating performance of the heat collector greatly, improves the overall efficiency, keeps the compound insulating layer from aging, and guarantees a long service life, and thus improves the thermal efficiency of the heat collector.
Description
Technical field
The utility model relates to solar thermal collector, is a kind of heat pipe collector with composite heat-insulating layer.
Background technology
Standpipe in the solar heat collector generally adopts materials such as mineral wool, mineral wool or glass foam to be incubated, but, these heat-insulation layers are quick aging at high temperature easily, causes making its heat-insulating property to reach better level, causes the thermal efficiency reduction of heat collector etc. easily.
Summary of the invention
The purpose of this utility model provides a kind of heat pipe collector with composite heat-insulating layer, adopts composite heat-insulating layer that standpipe is incubated, and to reach the raising heat-insulating property, improves the purpose of the thermal efficiency.
The utility model for achieving the above object, be achieved through the following technical solutions: heat pipe collector with composite heat-insulating layer, comprise framework, vacuum tube is installed on the framework, framework one end is installed header, and standpipe is installed in the header, and the standpipe periphery coats the mineral wool layer, mineral wool layer periphery coats aluminium foil layer, and the aluminium foil layer periphery coats layer of polyurethane.The layer of polyurethane periphery closely is connected with the inwall of header.Aluminium foil layer is made up of 2-6 layer aluminium-foil paper.The thickness of layer of polyurethane is greater than the thickness of mineral wool layer.
Advantage of the present utility model is: owing to adopt composite heat-insulating layer in this heat collector, heat collector integral heat insulation performance has been had by a relatively large margin improve, improved whole efficiency, composite heat-insulating layer is difficult for aging, long service life, thus the thermal efficiency of heat collector is improved a lot.
Description of drawings
Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is A-A section structure for amplifying schematic diagrames in the accompanying drawing 1.
The specific embodiment
2 is frameworks among the figure, and vacuum tube 1 is installed on the framework 2, and framework 2 one ends are installed header 3, and standpipe 4 is installed in the header 3, and standpipe 4 peripheries coat mineral wool layer 5, and mineral wool layer 5 periphery coat aluminium foil layer 6, and aluminium foil layer 6 peripheries coat layer of polyurethane 7.Layer of polyurethane 7 peripheries described in the utility model closely are connected with the inwall of header 3.Described aluminium foil layer 6 can be made up of 2-6 layer aluminium-foil paper, and it can further be locked in inside with heat loss through radiation.In order further to increase heat-insulating property, make the thickness of the thickness of layer of polyurethane 7 greater than mineral wool layer 5.Aluminium foil layer 6 described in the utility model adopts aluminium foil layer or aluminium foil to make.Mineral wool layer 5 described in the utility model is locked in higher temperature in the resistant to elevated temperatures glassy layer in insulation, and aluminium foil layer 6 is locked in inside with heat loss through radiation, and layer of polyurethane 7 is the assurance integral heat insulations further.The utility model is mainly used on the split-type solar energy heat collector, under the situation that does not change the heat collector profile, has effectively improved the heat-insulating property of heat collector, thereby has improved collecting efficiency.
