Description

Thermal-pipe two-way insertion solar water heater

The utility model relates to the two-way plug-in type solar water heater of a kind of heat pipe.

Chinese patent CN91223458.X discloses a kind of combined type solar hot-water device of can passing the winter, this device solves not bursting by freezing of water-supply-pipe, and with technical problems such as removable heat pipe corrosion proof and leakproofs.But the shortcoming of this device is heat pipe and casing junction all is equipped with sealing device, increased the complexity of structure design and processes, if gasket seal have shortcoming, assembling wrong, can not guarantee that 100% is water-tight, also have that this device setting angle is irreconcilable not to have a solar absorber plate.

Chinese patent CN89217272.X discloses a kind of overall vacuum pipe water heater of passing the winter.This device as heat collector, is finished thermosyphon circulation by water self with vacuum tube, realizes antifreeze function by cold water emptying.But the shortcoming of this device is, there is sealing device vacuum tube and water tank junction, be easy to generate during mounting or dismounting and leak, realize that by cold water emptying antifreeze use is inconvenient, because vacuum pipe inner cavity directly contacts hot and cold water, when the temperature difference of water and vacuum glass tube cavity is big, glass tube with vacuum be easy to generate split broken, and in case a glass tube with vacuum split broken meeting and cause this device integral body to leak.

The utility model has been drawn above-mentioned advantage, has improved above-mentioned shortcoming.A kind of heat pipe and water tank of making is provided, adopts the little gap two-way inserted mode that is slidingly matched to connect between the vacuum tube, need not any sealing device, the two-way plug-in type solar water heater of the heat pipe that lighting angle is adjustable.

The technical solution of the utility model is: this water heater is by heat collector that is made of skeleton case (3), pressing plate (14), transparent cover plate (10), cushion film (8), vacuum tube (11), heat pipe (12), reflecting plate (13) and the attemperater formation that is made of band fin heat transfer pipe (4), water tank (5), heat-insulation layer (6), shell (1), water inlet pipe (2), outlet pipe (18), overflow pipe (19), blast pipe (20) are installed on adjustable support (7) and the connecting rod (15).Heat-collecting box and attemperater are fused by skeleton case (3).Be characterized in: 1. the outer surface of heat pipe (12) is with the little gap two-way insertion method that is slidingly matched, one end is connected with heat-transfer pipe (17) inner surface in the water tank (5), the other end is connected with cork (7) with vacuum tube (11) inwall, 2. there is adjustment hole (7A) adjustable support (7) lower end, 3. the outer surface of heat-transfer pipe (17) is equipped with radiating fin (16), and 4. an end outer surface of heat pipe has solar absorbing layer.

Vacuum tube can be a garden shape or square etc., and material can be glass or lucite.

The heat-insulation layer of this water heater can be a rock wool, or foamed plastics, or slag wool.

The material of the water tank of this water heater (5) can be an aluminium, or copper, or stainless steel, or antirust iron sheet.

The transparent cover plate of this water heater (9), (10) can be glass, or lucite, or transparent plastic film.

The fin of this water heater (16) can be garden type or square or screw type, and material can be aluminium, or copper, or stainless steel, but should and heat-transfer pipe (17) be identical material.

The heat pipe of this water heater (12) is characterized in: in heat pipe, be filled with the working media that does not freeze winter, and as fluorine Lyons, or alcohol.

Below in conjunction with accompanying drawing an embodiment of the present utility model is elaborated.

Fig. 1 is the utility model structural representation.

Fig. 2 is heat pipe and water tank, vacuum tube mounting structure schematic diagram.

Fig. 3 is the utility model scheme of installation.

Fig. 4 is a water inlet pipe and water outlet pipe attemperator cross section structure schematic diagram.

As Fig. 1, shown in Figure 3, cold water enters water tank (5) by water inlet pipe (2), and unnecessary water can be discharged by overflow pipe (19).Heat-insulation layer (6) is arranged around the periphery of water tank (5).Water tank (5) all adopts welding method to constitute one with the junction of heat-transfer pipe (17), water inlet pipe (2), outlet pipe (18), overflow pipe (19), bleeder pipe (20).As shown in Figure 2, radiating fin (16) is to adopt slight interference method of press-fitting or welding method to link into an integrated entity with heat-transfer pipe (17).The outer surface of heat pipe (12), adopt the little gap two-way inserted mode that is slidingly matched, one end is connected with heat-transfer pipe (17) inner surface in the water tank (5), the other end is connected with vacuum tube (11) inner surface, cork (9), skeleton case (3) fuses heat collector and attemperater, with bolt (7B) adjustable support (7) is connected with connecting rod (15), skeleton case (14), with changing the method for connecting rod (15), adjust the lighting angle of this water heater at the rigging position in the accent hole of adjustable support (7) (7A).

As Fig. 1, shown in Figure 3, after sunshine sees through transparent cover plate (10), shine vacuum tube (11) and reflecting plate (13), direct projection and sunlight reflected see through the vacuum layer of vacuum tube (11), absorb the back from passing to heat-transfer pipe (17) and radiating fin (16) at a high speed, expeditiously by heat pipe (12), pass to the cold water in the water tank (5) again, along with solar light irradiation time lengthening, the heat of passing to cold water increases, and water in water tank just progressively heats up.Owing to adopt vacuum tube (11) and transparent cover plate (10) and heat-insulation layer (6), the solar heat that water heater absorbs is not easy to scatter and disappear.The water that heats up flows out through outlet pipe (18) and uses for the user.Unnecessary steam pressure in the water tank (5) is drained by bleeder pipe (20).What be connected with water inlet pipe and water outlet pipe (2), (18) of this water heater as shown in Figure 4 is delivered into the peripheral insulation construction by heat-insulation layer (21) and plastic tape (23) formation of outlet pipe (22), thereby water inlet and leaving water temperature be not subjected to ectocine, and this water heater all can use throughout the year.

Characteristics of the present utility model have been expressed in above-mentioned explanation: 1. heat pipe and water tank, vacuum tube adopt the little gap two-way inserted mode that is slidingly matched to be connected, need not any sealing device, can guarantee that 100% is water-tight. 2. owing to adopt vacuum tube heat absorbing, adopt hot tube high-efficiency to conduct heat, adopt again heat-insulation layer, radiating fin, transparent cover plate, reflecting plate etc., so thermal efficiency height. 3. employing adjustable support is so lighting angle is adjustable. 4. because the working media that water inlet pipe and water outlet pipe adopts filling in insulation construction, the heat pipe not freeze winter has heat-insulation layer around the water tank, so can both use throughout the year. 5. owing to adopt detachable combination design, so very convenient when mounting or dismounting, maintenance, transportation.

Above-described embodiment can be found out, the utility model, novel structure, thermal efficiency height, cost are lower, easy to install, safe and reliable, the life-span long, 1 year spring, summer, autumn and winter can both provide hot water, and the family and the collective that are fit to China east, south, west, northern any area use.
