Abstract

The utility model relates to a pressurized natural circulation type wall-hung solar energy hot water heater belonging to a technical field of solar energy hot water heater manufacture, comprising a glass vacuum heat collection tube, a horizontal hot tube, a co-jointed tank inner body, a co-jointed tank inner body, a co-jointed tank outer shell, a tail box, a heat circulation tube, a reflux circulation tube, a hot water output tube, a heat preservation water tank and an electric heating tube. Wherein the heat absorption end of the horizontal hot tube passes through the glass vacuum heat collection tube, the heat discharge end of the horizontal hot tube passes through the co-jointed tank inner body, the co-jointed tank inner body is arranged in the co-jointed tank outer shell by heat preservation foam material, the co-jointed tank outer shell and the tail end are respectively connected with a support, the heat circulation tube and the tap water tube are respectively connected with the heat preservation water tank. During use, the glass vacuum heat collection tube obtains the heat energy from the sunlight, then the heat energy is transferred to the circulation water of the co-jointed tank inner body rapidly, the rise of the hot water makes the water in the heat perversion water tank be heated constantly, due to the pressurized operation, the outputted hot water has large pressure and is comfortable for bathing.

Description

Pressure-bearing natural recirculating type wall-hanging solar water heater

Technical field

The utility model relates to a kind of pressure-bearing natural recirculating type wall-hanging solar water heater, belongs to solar water heater manufacturing technology field.

Background technology

Present pressure wall-mounted solar water heater, adopt U-shaped pipe medium heat exchange or water cycle heat exchange mostly, because of its reasons in structure, Natural Circulation heat exchange effect is bad, adopt forced circulation, and the heat exchange of employing heat pipe-type, because the pressure-bearing water shutoff technical barrier of heat pipe release end of heat and header inner bag interface, the release end of heat of heat pipe is not directly contacted with the recirculated water of header inner bag, but conduct heat by additional disrance sleeve, or the heat pipe release end of heat is welded on the outer surface of header inner bag, by metal pipe-wall heat conduction, thermal resistance is bigger, causes the partial heat energy loss.

Summary of the invention

The utility model is at the deficiencies in the prior art, provide a kind of reasonable in design, simple in structure, use pressure-bearing natural recirculating type wall-hanging solar water heater reliable, that have higher heat exchange efficiency.

The purpose of this utility model is achieved through the following technical solutions: a kind of pressure-bearing natural recirculating type wall hanging solar energy water heater, mainly by glass heat-collecting vacuum tube, Horizontal heat pipe, header inner bag, header shell, tail end box, heat circulation pipe, reflux cycle pipe, hot water delivery pipe, running water pipe, attemperater, electrical heating and blowdown Butterworth Hatch are formed.Wherein, the heat absorbing end of Horizontal heat pipe penetrates in the glass heat-collecting vacuum tube, release end of heat penetrates in the header inner bag, the header inner bag is fixed in the header shell by heat-insulation foam material, the header shell all is connected with support with the tail end box, heat circulation pipe and reflux cycle pipe, the hot water delivery pipe all is connected with attemperater with running water pipe.

Described Horizontal heat pipe is that inside is filled with heat-exchange working medium, the tube wall metal heat-conducting pipe with the closed at both ends with certain vacuum degree of metallic fiber, capillary suction-operated because of metallic fiber, make not rely on gravity after the heat-exchange working medium condensation and just can be back to heat absorbing end, can be used for horizontal heat conduction.

Described header inner bag takes the shape of the letter U, and wherein an end is a heat circulation pipe, and the other end is the reflux cycle pipe, and the upper orifice position is provided with hickey.Because of bearing operation, the section of heat circulation pipe and reflux cycle pipe is circle.Heat circulation pipe is thicker, and longitudinally axis is evenly distributed with the short tube of some band seal grooves that stretch out to the both sides level, is used to insert the release end of heat of Horizontal heat pipe, and the reflux cycle pipe is thinner, is communicated with heat circulation pipe in the bottom of header inner bag.

When the utility model uses, glass heat-collecting vacuum tube from the sunlight width of cloth hit obtain heat energy after, conduct to rapidly by Horizontal heat pipe in the recirculated water of header inner bag, because being vertical direction substantially, installs the header inner bag, being heated afterwards by the recirculated water of some Horizontal heat pipe release end of heat heating, proportion lightens, rising from bottom to top along heat circulation pipe, rise in the attemperater always, because the hot water in the heat circulation pipe rises, be negative pressure in the return duct that the bottom is communicated with, the lower water of temperature of attemperater bottom is drawn into the header bottom, so forms the thermal siphon Natural Circulation between header inner bag and the attemperater, the water in the attemperater constantly is heated.Running water pipe in service is always on-state, tap water pressure is all born on header inner bag and attemperater and hot water delivery pipe road, when opening hot water valve on the hot water delivery pipe or shower, the hot water that is in the attemperater upper strata is ejected, because of water delivery pressure is big, running water pipe and hot water delivery pipe all can adopt the minor diameter pipeline, do not limit and turn and pipeline length, made things convenient for the hidden of construction and hot and cold water pipeline and decorated, have reasonable in design, convenient and practical, etc. advantage.
