Abstract

The utility model provides a low-heat loss heat preservation water tank of a flat type solar water heater, comprising a water tank liner, a heat transfer medium layer, a middle liner body, a heat preservation layer and a water tank shell body, wherein the outer surface of the middle liner body is additionally stuck with a heat insulating film, and a water inlet pipe and a water outlet pipe are both communicated with the water tank liner by a linkage heat insulation control valve; the linkage heat insulation control valve can control simultaneous opening or closing of the water inlet pipe and the water outlet pipe, and ensures that the hot water in the water tank liner is separated from the water inlet pipe and the water outlet pipe when the hot water is not used; the pipes adopt the double layer heat preservation structure of heat insulating film and heat preservation sleeve, thereby maximally lowering the heat loss of the water tank. Tests show that compared with the prior heat preservation water tank, the heat preservation water tank adopting the structure has the heat loss lowered by 30 to 35 percent, so that the utility model is truly a low-heat loss heat preservation water tank.

Description

The low-heat-losing thermal water tank of flat plate solar water heater

Technical field:

The utility model relates to a kind of flat solar water heater, relates in particular to attemperater wherein.

Background technology:

In existing flat solar water heater, its attemperater is made up of inner water tank 1, heat-conducting medium layer 2, middle courage body 3, heat-insulation layer 4 and tank shell 5 from inside to outside successively, heat-conducting medium layer 2 links to each other with flat type solar heat collector by conduit 6, water inlet pipe 7 and outlet pipe 8 all communicate with inner water tank 1, and water inlet pipe 7 is arranged on the bottom of inner water tank 1, and outlet pipe 8 communicates with hot water conduit 9 in the inner water tank 1.Through analysis of experiments, water inlet pipe 7, outlet pipe 8, conduit 6 and middle courage body 3 are main heat radiation points of attemperater, and its heat scatter ratio, scatter and disappear ratio accounts for about 60% of whole attemperater system heat leakage.Along with the great attention of countries in the world to the solar energy utilization, solar energy and architecture-integral design have been risen to quite high scientific research position, people press for a kind of plate type solar water heater of low heat waste, promptly must make up, to adapt to the demand of skyscraper balcony formula high-efficient flat-plate solar water heater with the flat-plate solar collector of low heat waste and the attemperater of low heat waste.

The utility model content:

The purpose of this utility model provides a kind of low-heat-losing thermal water tank of flat plate solar water heater, to adapt to modern high-rise building the demand of balcony formula high-efficient flat-plate solar water heater must be installed.

The technical scheme that the utility model is taked is:

The low-heat-losing thermal water tank of described flat plate solar water heater, comprise inner water tank 1, heat-conducting medium layer 2, middle courage body 3, heat-insulation layer 4 and tank shell 5, heat-conducting medium layer 2 links to each other with flat type solar heat collector by conduit 6, water inlet pipe 7 and outlet pipe 8 all communicate with inner water tank 1, and water inlet pipe 7 and outlet pipe 8 all are arranged on the bottom of inner water tank 1, outlet pipe 8 communicates with hot water conduit 9 in the inner water tank 1, it is characterized in that: the outer surface at middle courage body 3 posts thermal isolation film 10, water inlet pipe 7 and outlet pipe 8 all communicate with inner water tank 1 by the heat insulation control valve 11 that links, outlet pipe 8 is connected with hot water conduit 9 in the inner water tank 1 by the heat insulation control valve 11 that links, and is enclosed with thermal isolation film 10 and thermal insulation casing 13 outside conduit 6 successively.

Further, the caliber of water inlet pipe 7 is greater than the caliber of outlet pipe 8; In inner water tank 1, above water inlet pipe 7, be provided with baffle plate 12.

Owing to stick on thermal isolation film 10 at the outer surface of middle courage body 3, water inlet pipe 7 and outlet pipe 8 all interlink with inner water tank 1 by the heat insulation control valve 11 that links, link heat insulation control valve 11 for opening or close outlet pipe 8 and water inlet pipe 7 simultaneously, when guaranteeing not user mode, hot water in the inner water tank 1 and water inlet pipe 7 and outlet pipe 8 are isolated; If adopt the caliber of the caliber of outlet pipe 8 less than water inlet pipe 7, then water outlet just can have feeling of stress; The media lines 6 that connects attemperater and flat plate collector adopts thermal insulation casing and thermal isolation film 10 double-layer heat insulations, reduces the water tank heat waste to greatest extent.Through test determination, the attemperater of this structure is compared with existing attemperater, can reduce heat waste 30%～35%, is real low heat waste type attemperater.
