Description

Dual-opening type high-capacity vacuum tube solar water heater

(1) technical field:

The utility model relates to a kind of domestic solar-energy water heater, especially relates to a kind of dual-opening type high-capacity vacuum tube solar water heater of not establishing storage tank.

(2) background technology:

At present, China's solar energy vacuum glass thermal-collecting tube technology maturation, good product quality, low price has become the leading products of the market supply.But because the vacuum tube internal diameter is little, be generally 33～43mm, volume 0.8～1.2L/m only possesses heat collection function, must rely on water storage cylinder to carry out heat exchange.Though the vacuum tube price is not high, water storage cylinder processing technology more complicated cost height.With the 150L solar vacuum-tube water heater is example, and the water storage cylinder cost is about 800 yuan, and 20 1500 * 47mm vacuum tubes only need about 350～400 yuan, add the price that accessory such as upper bracket also is no more than water storage cylinder, and the complete machine accessory is many, and assembling is complicated.Therefore, water storage cylinder cost height, structure assembling complexity is to influence the main cause that solar vacuum-tube water heater is popularized.

(3) summary of the invention:

It is one that the purpose of this utility model is to provide a kind of thermal-arrest, heat exchange, heat accumulation water, simple in structure, installation and easy to use, and can the dual-purpose dual-opening type high-capacity vacuum tube solar water heater of weather.

The purpose of this utility model is achieved through the following technical solutions, it is made up of thermal-collecting tube, fixed frame, it is characterized in that: thermal-collecting tube is the dual-opening type vacuum tube that all there is through hole at two ends, form by inner bag, shell, it between inner bag and the shell all-sealed vacuum interlayer, the length and the number of fixed frame length and width size and vacuum tube are complementary, establish the water pipe that is connected with the dual-opening type vacuum tube in the upper and lower side frame, quantity according to the dual-opening type vacuum tube has corresponding installing hole, and dual-opening type vacuum tube and fixed frame are tightly connected.

The utlity model has following advantage:

1, simple in structure.The dual-opening type vacuum tube is made up of inner bag, heat-sink shell, shell.Inner bag and shell are made of 3mm heavy sheet glass pipe, and the 10mm interlayer is a vacuum layer between the two.Heat-sink shell is made of layer of copper (aluminium) gauze and layer of copper (aluminium) sheet.And, vacuumize processing at last after fusion process closes up inner bag and outer casing shell pipe and seals.Because without water storage cylinder, only need in the framework that the water pipe tube connector is housed the dual-opening type vacuum tube is connected and fixed.

2, thermal efficiency height.The vacuum tube heat absorbing material helps increasing endotherm area because of adopting copper (aluminium) sheet and copper (aluminium) gauze composite construction, improves the photo-thermal conversion ratio.Above-mentioned material is through electroplating the melanism treatment process, and black coating is prolonged constant, adds the booster action that there is the sunlight reflected plate at the upper frame back side, has strengthened intensity of illumination, and thermal conversion rate can reach about 60%.Because be provided with the polyurethane insulating foam layer in upper and lower side frame side's aluminum pipe, dual-opening type vacuum tube layer vacuum is≤5 * 10Pa ^-2, reach the heat insulation effect of thermos bottle substantially.

3, good airproof performance.Because dual-opening type vacuum tube caliber is big, the mouth of pipe is little, and thermos flask shape spout diameter has only about 35mm, helps sealing.The utility model also special connects the steel wood Luo cap that is complementary with the vacuum tube installing hole in straight-through except silicone gasket is sealed in design.This Luo cap both can pass through the fastening mouth of pipe of spinning silica gel sealing ring, connect Luo line sealing antiseepage problem in can solving self and lead directly to by the timber imbibition again, can also reduce the heat conduction and scatter and disappear.

4, pattern is attractive in appearance.The utility model does not have storage tank, and complete machine thickness is no more than the diameter of dual-opening type vacuum tube, and fuselage is lightly attractive in appearance, both can on platform, install, also can be hung on the exterior wall, especially be directly installed on the roofing of sloping top without support, can merge one with building, seem very harmonious.

5, easy to use.The utility model has been installed electric heating tube in the lower frame water inlet pipe, mix the control corresponding device after, have automatic loading water, functions such as automatic temperature-controlled electrical heating realize that weather is dual-purpose, full-time heat supply.Because complete machine dispatches from the factory, need not show the field boundary assembling, easy to maintenance, bring very big facility to the user.

6, cheap.Because dual-opening type vacuum tube cost is not high, does not need storage tank, parts are few in addition, and thin thickness can the complete machine packing dispatch from the factory, and transportation and on-the-spot mounting cost are low, and the after-sale service expense is also low, so low price.According to measuring and calculating, 100 with 150L dual-opening type vacuum tube water heater with compare with the ordinary vacuum tube water heater of capacity band storage tank, it is cheap 30～40% that the dual-opening type vacuum tube water heater is wanted, and has the very strong market competitiveness.
