Abstract

The utility model relates to a composite wall hanging water heater, a vacuum heat collecting pipe of which is sheathed outside a pressure bearing inner liner. The middle of the vacuum heat collecting pipe is provided with a heat insulating layer. An interlayer is formed between the inner wall of the heat collecting pipe and the pressure bearing inner liner and filled with heat conducting medium. A water inlet pipe and a water outlet pipe are arranged on the inner liner. The water outlet pipe is connected with a valve through a water outlet pipeline. A reflecting plate is connected with a guard net and sheathed outside the vacuum heat collecting pipe through an elastic clip. A heat collecting part is supported on a bracket through a barrel support. A heat insulating mattress is fixed on the inner liner through bolts. Cold water is added after the valve is opened; heat is absorbed by absorbing film arranged on the inner wall of the heat collecting pipe and transferred to the inner liner by the heat conducting medium to make cold water heated.

Description

Combined type wall-hanging solar water heater

The utility model relates to the installation that a kind of combined type wall-hanging solar water heater can adapt to the solar water heater of high floor or special construction building, belongs to the technical field of solar water heater.

Existing wall-hanging solar water heater mostly adopts water tank and heat collector separately, realize thermal-arrest by convection current or passive type circulation, shortcoming is that circulation line is long, and the thermal efficiency is low and heat waste is big, and arrange to have relatively high expectations because of pipeline and directly influence the thermal efficiency, therefore complexity and quality instability are installed.In addition, this kind structure bearing capacity is low, insulation difficulty, fault rate height.

The purpose of this utility model is that a kind of combined type wall-hanging solar water heater will be provided, and it can overcome above-mentioned shortcoming.The main body heat collector of water heater and the compound one of water storage part, promptly there is a pressure-bearing metal inner bag to be contained in the inside of the ultra-large type all-glass vacuum tube inner bag of heat collector as the storage tank of water heater, by all-glass vacuum thermal-collecting tube heat absorption and pass to water in the metal inner tube heating inner bag, heat collector and beam condensing unit are fixed on the support by barrel, support can directly be connected with the building of perpendicular, and the optically focused reflector is enclosed within the heat collector outside in order to increase heat collector surface.Only need open the outlet pipe valve during water intaking, cold water replenishes automatically, and convenient and reliable operation can realize the automation function of solar water heater.

The purpose of this utility model is achieved in that all-glass vacuum thermal-collecting tube (1) is sleeved on pressure-bearing inner bag (2) outside.This thermal-collecting tube is the U font, has muff (7) in the middle of it; Form an interlayer (9) between the inwall (5) of vacuum heat collection pipe (1) and the pressure-bearing inner bag (2), heat-conducting medium (20) wherein is housed, water inlet pipe (4) and outlet pipe (3) are housed on the inner bag (2); Between muff (7) and the vacuum heat collection pipe (1) sealing ring (8) is housed, outlet pipeline (21) joins with valve (19).

Inner bag (2) is connected with bolt (12) with heat insulating mattress (15), barrel (12) bottom is fixed in heat insulating mattress (15) with bolt (14), reflector (17) links together with protection network (10), be sleeved on vacuum heat collection pipe (1) outside by elasticity folder (11), barrel (12) is fixed on the support (18) with bolt (16).

Now in conjunction with the accompanying drawings the structure of combined type wall-hanging solar water heater is described in detail:

By Fig. 1, all-glass vacuum thermal-collecting tube (1) is sleeved on pressure-bearing inner bag (2) outside, all-glass vacuum thermal-collecting tube (1) is the U font, has muff (7) in the centre of thermal-collecting tube (1), form an interlayer (9) between the inwall (5) of vacuum heat collection pipe (1) and the pressure-bearing inner bag (2), air, heat transmission fin or other heat-conducting mediums (20) are arranged in the interlayer (9); Water inlet pipe (4) and outlet pipe (3) are housed on the inner bag (2), between muff (7) and the vacuum heat collection pipe (1) sealing ring (8) are housed.Outlet pipe (3) joins by outlet pipeline (21) and valve (19) again.Scribble selective absorbing film (6) on the inwall (5) of vacuum heat collection pipe (1), can absorb radiations heat energy.

By Fig. 2, above-mentioned thermal-arrest partly is fixed in above the support (18) with bolt (16) by barrel (12), and barrel (12) bottom uses bolt (14) to be fixed in heat insulating mattress (15) again.This heat insulating mattress also uses bolt (12) to be connected with inner bag (2), and reflector (17) connects together with protection network (10), is sleeved on vacuum heat collection pipe (1) outside by elasticity folder (11).

Will go up water earlier when water heater uses, open the valve (19) on the outlet pipe (3) earlier, running water just enters from water inlet pipe (4), is valve-off (19) till outlet pipe (3) there are flowing out; When solar radiation, the selective absorbing film (6) on the inwall of all-glass vacuum thermal-collecting tube (5) absorbs heat, conducts heat to pressure-bearing inner bag (2) by the heat-conducting medium (20) in the interlayer (9), and the cold water in the inner bag (2) is heated; As long as open outlet pipe valve (19) during use.

Compared with prior art, combined type wall-hanging solar water heater has following advantages: 1. water tank and inner bag are placed on directly heat absorption in the heat collector (all-glass vacuum thermal-collecting tube), reduce thermal resistance, thermal effect The rate height. 2. there is not circulation line and by the insulation of high vacuum and anti-reflection layer, heat waste is little. 3. inner bag is manufactured by the stainless steel of δ=0.8mm～105mm, is equipped with two mouths of a river, the bearing capacity height. 4. complete machine is in light weight, and assembly is few, simple installation. 5. reflective arc can be regulated arbitrarily setting angle according to local latitude.
