Technical field
The utility model relates to a kind of solar thermal collector, relates in particular to the U-shaped tube solar heat-collecting device of a kind of coiled.
Background technology
U-shaped tube solar heat-collecting device is by parts such as thermal-arrest box, copper coin core, vacuum tube, tailstock and tailstocks.Copper coin core price, and the water capacity of relative Stainless Steel Coil is little, U-shaped copper pipe adopts parallel-connection structure, and main line and U-shaped copper pipe are connected in parallel after adopting welding.
U-shaped copper pipe also needs the aluminium wing of special construction to be combined with U-shaped copper pipe, purpose first is to fix U-shaped copper pipe not at the vacuum tube inside shaking, the secondth, fitting with the vacuum tube inwall absorbs heat, and the heat that vacuum tube is absorbed passes to copper pipe, thereby the water in copper pipe is heated up.
U-shaped tube solar heat-collecting device of the prior art, the water nozzle outlet is substantially all that an end import one brings out mouth, and be used for the words of small-sized household solar energy system, preferably the outlet form of water nozzle is one to bring out mouth, like this, the pipeline of other end outlet will do also that insulation makes two water nozzles again and to connecting together heat storage water tank.Its shortcoming is: the copper pipe diameter is less, and heat-transfer working medium can not use running water, causes the operation of heat collector localized hyperthermia otherwise incrustation scale can stop up U-shaped copper pipe.
Summary of the invention
The purpose of this utility model is to provide that a kind of cost of manufacture is low, the U-shaped tube solar heat-collecting device of the coiled of good in thermal property.
The purpose of this utility model is achieved through the following technical solutions:
The U-shaped tube solar heat-collecting device of coiled of the present utility model, comprise the thermal-arrest box, be provided with the plate core box in described thermal-arrest box, be provided with coil pipe plate core in described plate core box, described plate core box is connected with vacuum tube, the crooked position of described coil pipe plate core reaches in described vacuum tube, and described coil pipe plate core is provided with circulating water intake and circulating water outlet.
Can be found out by the technical scheme that above-mentioned the utility model provides, the U-shaped tube solar heat-collecting device of the coiled that the utility model embodiment provides, owing to comprising the thermal-arrest box, be provided with the plate core box in the thermal-arrest box, be provided with coil pipe plate core in the plate core box, the plate core box is connected with vacuum tube, and the crooked position of coil pipe plate core reaches in vacuum tube, coil pipe plate core is provided with circulating water intake and circulating water outlet, and cost of manufacture is low, good in thermal property.
Description of drawings
The structural representation of the U-shaped tube solar heat-collecting device of coiled that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the structural representation of plate core box in the utility model embodiment;
Fig. 3 is the structural representation of the utility model embodiment mid-game tube sheet core.
In figure: 1. thermal-arrest box, 2. plate core box, 3. coil pipe plate core, 4. sealing ring, 5. vacuum tube, 6. tailstock, 7. tailstock.
The specific embodiment
The below will be described in further detail the utility model embodiment.
The U-shaped tube solar heat-collecting device of coiled of the present utility model, its better specific embodiment is:
Comprise the thermal-arrest box, be provided with the plate core box in described thermal-arrest box, be provided with coil pipe plate core in described plate core box, described plate core box is connected with vacuum tube, the crooked position of described coil pipe plate core reaches in described vacuum tube, and described coil pipe plate core is provided with circulating water intake and circulating water outlet.
The position that described plate core box is connected with vacuum tube is provided with sealing ring.
Described coil pipe plate core is the corrosion resistant plate core.
Foam by polyurethane integral between described plate core box and thermal-arrest box.
The lower end of described vacuum tube is provided with tailstock and tailstock.
The utility model absorbs by vacuum tube and passes to inner coil pipe plate core after heat, and coil pipe plate core inner coolant-temperature gage is raise, and the low and technique of cost of manufacture is better than traditional U-shaped tube solar heat-collecting device, and the hot property aspect increases.
In manufacturing process, length can be carried out U crook reason through the coil pipe of adjusting, again the U-shaped coil pipe of vacuum tube inside is fixed with vacuum tube and coordinates, water return pipeline is placed in the plate core box, plate core box and sealing ring in the thermal-arrest box can be fixed vacuum tube upper orifice position and return pipe is placed in inside.Plate core box and sealing ring in the thermal-arrest box can absorb the surplus air heat on vacuum tube top, and be conducive to the cross-ventilation of vacuum tube top and the bottom, increase the heat exchange amount.The outlet aspect, one brings out mouth, and return pipe is inner at heat-insulation layer, has reduced external insulation.
The U-shaped tube solar heat-collecting device of coiled of the present utility model becomes the material of the plate core segment of the U-shaped tube solar heat-collecting device of tradition the material of stainless steel 304; Reduced manufacturing cost, coil pipe coordinates the aluminium alar part that has reduced traditional U-shaped pipe with vacuum tube; Coil pipe has increased the heat exchange area that contacts with the vacuum tube inner air, can improve the whole efficiency of heat collector; Return pipe is built-in, and Inlet and outlet water one brings out mouth, is convenient to being connected of domestic solar and storage tank; The coil pipe internal diameter strengthens, and can directly use running water as heat-transfer working medium.
Specific embodiment:
As Fig. 1, Fig. 2, shown in Figure 3:
Intercept corresponding size after will the corrosion resistant plate core calculating through size, then carry out U crook reason according to the heat collector tube pitch.Plate core box 2 is for two halves is welded, and half needs piercing and flanging to process, and then sealing ring 4 is installed, and after coil pipe plate core 3 is placed in plate core box 2, will carry out soldering after plate core box 2 and 3 combinations of coil pipe plate core.Tailstock 7 and tailstock 6 are used for supporting the vacuum tube afterbody and are convenient to install fixing.Foam by polyurethane integral between plate core box 2 and thermal-arrest box 1, guarantee thermal-arrest and heat-insulating property.
