Abstract

The invention discloses a vacuum heat preservation flat-plate solar collector, comprising a collector shell, a heat absorption plate core assembled in the collector shell, and a transparent cover plate connected with an opening at an upper part of the collector shell in a sealed manner. The collector shell consists of an inner shell and an outer shell; an upper end of the inner shell is connected with an upper end of the outer shell in a sealed manner; a vacuum heat preservation interlayer is formed by vacuumizing between the upper end of the inner shell and the outer shell, so as to realize the vacuum heat preservation in the flat-plate solar collector, achieve good heat preservation property, greatly reduce the heat loss of the flat-plate solar collector and improve the heat efficiency of the flat-plate solar collector. The inner shell and the outer shell of the collector shell are respectively integrally formed, so as to greatly simplify a mounting process of the flat-plate solar collector. The flat-plate solar collector is convenient to mount; no butt-joint seam is reserved or no sharp corner is formed; the occurrence of water leakage and injuries can be effectively prevented; and the vacuum heat preservation flat-plate solar collector has beautiful appearance.

Description

The vacuum heat-preserving flat-plate solar collector

Technical field

The present invention relates to a kind of solar thermal collector, more particularly, relate to a kind of vacuum heat-preserving flat-plate solar collector.

Background technology

Traditional flat-plate solar collector mainly is the housing that is formed by connecting on four frames, is installed in absorber plate in the confined space of the housing that is assembled by frame, is installed in the transparent cover plate on the top of the housing that is assembled by frame; Be installed in following press strip, the backboard of the bottom of the housing that assembles by frame; The comb, the collector that are arranged on the absorber plate bottom constitute, and transparent cover plate is pressed on the top of the housing that is assembled by frame through four ceiling moldings, and adopt securing member to fix; Ceiling molding leaves abutment joint and forms wedge angle in each corner; Abutment joint can cause and leak, and wedge angle can be hurted sb.'s feelings, and influences the attractive in appearance of product; Complex structure, difficult installation.In addition, need be incubated by the dress insulation material on backboard top, volatile matter produces and the meeting moisture absorption because insulation material has, and causes the heat-insulating property of insulation material to reduce greatly, is unfavorable for improving the thermal efficiency of flat-plate solar collector.Moreover, the housing of traditional flat-plate solar collector be by four independently frame be easy to generate problems of welded quality through being made of welded connection, production cost is high.

Summary of the invention

The objective of the invention is to overcome above-mentioned defective of the prior art; Provide a kind of production cost low, save material; Good heat insulating is convenient to install, and can effectively prevent to leak and the casualty accident generation; And product design is attractive in appearance, and can improve the vacuum heat-preserving flat-plate solar collector of the thermal efficiency of flat-plate solar collector.

For realizing above-mentioned purpose; Technical scheme provided by the invention is following: a kind of vacuum heat-preserving flat-plate solar collector is provided, comprises the heat collector housing, be installed in the heat-absorbing plate core in the heat collector housing; The transparent cover plate that is tightly connected with heat collector housing upper opening; Said heat collector housing is to be made up of inner housing, shell body, and said inner housing upper end is tightly connected with the shell body upper end, forms the vacuum heat-preserving interlayer through vacuumizing between inner housing upper end and the shell body.

Said vacuum heat-preserving interlayer is provided with the perforate that supplies collector to stretch out, and supplies collector to stretch out from this perforate, is equiped with sealing ring in this perforate.

Said perforate is to be made up of the sleeve pipe that an end is connected with inner housing and the other end is connected with shell body, and collector stretches out in sleeve pipe.

The beneficial effect of vacuum heat-preserving flat-plate solar collector of the present invention is: through constructing the heat collector housing that is made up of inner housing and shell body; Said inner housing upper end is tightly connected with the shell body upper end, forms the vacuum heat-preserving interlayer through vacuumizing between inner housing upper end and the shell body.Thereby realize that good heat insulating greatly reduces the heat loss of flat-plate solar collector, and can improve the thermal efficiency of flat-plate solar collector to carrying out vacuum heat-preserving in the flat-plate solar collector.And need not in the heat collector housing, to adorn insulation material; Can not only save material; Also solved the classic flat-plate solar thermal collector need in the heat collector housing, adorn insulation material be incubated existing insulation material can the moisture absorption; And insulation material can produce volatile matter and cause heat-insulating property poor, is unfavorable for improving the technical problem of the flat-plate solar collector thermal efficiency.

In addition, inner housing and shell body are one-body molded respectively, only need inner housing upper end and shell body upper end be tightly connected during assembling; Flat-plate solar collector is packed in the heat collector housing, and the heat collector housing is tightly connected through encapsulant and transparent cover plate, just can accomplish the assembling of flat-plate solar collector; Simplified the installation process of flat-plate solar collector greatly; Just can accomplish the assembling of heat collector housing, be convenient to install, can not leave abutment joint or form wedge angle; Can effectively prevent to leak, reach casualty accident and take place, and product design is attractive in appearance.

Below in conjunction with accompanying drawing and embodiment vacuum heat-preserving flat-plate solar collector of the present invention is described further.
