Description

Evacuated panel sunlight water heater

The utility model relates to a kind of water that with sunlight is thermal source is done in the medium exchange heat pipe with medium and heats device---the evacuated panel sunlight water heater of producing hot water.

At present, known commercially available solar vacuum-tube water heater is to adopt glass-vacuum tube to accept to be circulated to after sunlight directly heats water a kind of device of producing hot water of top heat preservation storage water tank, it must occupy the bigger light space that is subjected to, as roofdeck etc., this installs and uses all concerning the user that do not possess this space, high residential building and brings inconvenience, and every expense all, therefore fails to popularize more than 1000 yuan at RMB so far.

The purpose of this utility model provides a kind of evacuated panel sunlight water heater and improves the deficiency of solar vacuum-tube water heater on above-mentioned practicality and economy, makes it to be useful for general and high residential building, is used for little swimming pool, bathroom etc. by the modulus assembling; When the heat-collecting box daylighting area was 0.5 square meter, spring and summer autumn just can make according to shining that 60 kg of water are warmed up to 40～60 degrees centigrade in the heat preservation storage water tank in 4 hours, and 300 yuan/platform of the about RMB of price is by energy savings recoverable investment in 2～3 years.Based on this, under the modern technologies condition, it is convenient to design material source fully, at the bottom of technology is popularized cost, firm in structure, safe and reliable, adorn, remove, change all simple evacuated panel sunlight water heater and obtain social widely popularization;

The purpose of this utility model is achieved in that the case face that adopts combined glass vacuum plate sealing heat-collecting box, sunlight is entered form complete heating system in the case similar in appearance to boiler, and add hot water as heat carrier by heat exchange with medium, constantly flow into heat preservation storage water tank by thermodynamic principles circulation automatically thereafter and use for the user.Because glass vacuum plate has good printing opacity heat-blocking action, therefore make above-mentioned design under the condition at medium sunshine during empty the solarization, the temperature in the heat-collecting box also can reach more than 100 degrees centigrade;

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is that evacuated panel heat-collecting box of the present utility model is only installed figure in balcony.

Fig. 2 is the configuration structure of evacuated panel heat-collecting box.

Fig. 3 is the structure chart of glass vacuum plate.

1. evacuated panel heat-collecting boxes, 2. cold cycling water pipes, 3. heat preservation storage water tank, 4. supports, 5. safety chains, 6. glass vacuum plates, 7. endothermic tubes, 8. upper headers, 9. heat exchanger tubes, 10. safety valves, 11. lower collector pipe 12.U shape pipe clamp bolts, 13. heat absorbing sheets, 14. heat collecting tanks among the figure.

Evacuated panel heat-collecting box (1) is the external heat preservation storage water tank of safety chain (5) cold cycling water pipe (2) (3) in the frame groove that is inserted in support (4) in Fig. 1, heat preservation storage water tank can be installed as kitchen, toilet etc. by the user with specifying, also can provide self-chambering for oneself, but its bottom surface should be higher than the end face of heat-collecting box; In the time of outside being installed in balcony, must guarantee firmly and at the case face to add a cover Chain Link Fence safely;

In embodiment illustrated in fig. 2, evacuated panel heat-collecting box (1) is by the setting modulus 0.5 by daylighting area, 0.75,1.0 the one group of glass vacuum plate (6) of square metre design and the assembling thickness of endothermic tube (7) upper header (8) heat exchanger tube (9) safety valve (10) lower collector pipe (11) U-shaped pipe clamp bolt (12) heat absorbing sheet (13) heat collecting tank (14) and the rectangular box that designs, wherein endothermic tube (7) adopts thin metallic tubd tightly to be welded on the lower collector pipe (8) (11) by 80～100 millimeters spacings, fill with nontoxic liquid of lightweight such as alcohol or other high-quality seasoning liquid in the pipe as thermal medium, it with the heat that absorbs in upper header (8) with heat exchanger tube (9) in the continuous inflow heat preservation storage water tank (3) of water exchange heating back circulation; Adopting thermal medium is that the advantage of medium is: 1) never fouling and deposit dirt in the endothermic tube group, 2) the good heat exchange of boiling point lazy flow is fast, 3) antifreeze, be-32 degrees centigrade as the freezing point of alcohol.Be provided with 3～10 heat absorbing sheets (13) with endothermic tube (7) fastening on the frame of heat collecting tank (14), it is that conversion sunlight heat raising the temperature inside the box is necessary, and glass vacuum plate (6) played a supportive role, the top of upper header (8) is provided with safety valve (10) and shines the exhaust protection when causing superpressure and replenish medium as empty, and what there was a cold cycling water pipe at installing heat exchanger tube (9) two ends in the pipe connects mouth through this external heat preservation storage water tank (3); Upward be fixed on the base plate of heat collecting tank (14) with 4～6 M5U shape pipe clamp bolts (12) in last lower collector pipe (8) (11), spraying of the surface of above-mentioned heat absorbing element or electricity are baked and are very led full spectrum heat-absorbing material tunic; Glass vacuum plate (6) is that tight edge is stuck in heat collecting tank (14) the frame mouth groove one group as 4,6,8, the thin bar of plastics that the printing opacity heat resistanceheat resistant is pasted in the surrounding plays sealing and buffering effect when assembling, the purpose that the glass vacuum plate group is set is to be transparent heat insulating and repair and replacement easily; Heat collecting tank (14) adopts heat-resisting foam thermal insulation layer of galvanized sheet metal liner and heat reflection plate to make;

In the embodiment shown in fig. 3, glass vacuum plate (6) is a rectangle, adopts the high high-quality glass material of light transmittance, thick 2.5～5 millimeters of upper and lower plates face, 5～8 millimeters of intermediate gaps, plant glass tube or row culture ribbed stiffener in the space, 30～40 millimeters of spacings, vacuum is less than or equal to 0.05Pa;

Cold cycling water pipe (2) is the PAP of 15 millimeters of internal diameters; Heat preservation storage water tank (3) is made for the sticking thermal insulation layer that applies of the plastics of galvanized sheet metal or nontoxic heat-resisting anti-time, the lowest part that should tightly be installed in casing is chewed in connecing of linking to each other with the cold cycling water pipe, it is the upper strata liquid level with the hot water that assurance flows in the case that hot water connects the buoy position-controlled device of chewing in the connecting box, upper hose is installed in to be established threeway and distributes when 100 millimeters places at the bottom of the case and heat supply water pipe are shared, also can provide self-chambering for oneself; Support (4) is the steel bracket that designs according to with installing; Safety chain (5) is light and handy metallic bond.

Have the evacuated panel sunlight water heater of this device, not only hot effect can satisfy the requirement of heat supply, but has more given prominence to its practicality and economy, so its social popularization is reliable.
