Preferably, the caliber of described short copper pipe is 22mm.
Beneficial effect of the present invention is mainly reflected in:
1. adopt the short copper pipe of the long copper pipe of thermal medium connection thermal medium, the long copper pipe of cold medium to connect the mode of the short copper pipe of cold medium, and the long copper pipe of two ends shutoff by opposite side carries out water conservancy diversion, increased the flow path distance of current, improved the Heat-collecting effect of product;
2. adopt the larger short copper pipe of diameter to replace the short copper pipe that traditional diameter is less, the heating surface area of short copper pipe is increased, reduced the quantity of arranging of short copper pipe, reduced the weight of product simultaneously, reduced the cost of product;
3. adopt the less long copper pipe of diameter to replace the long copper pipe that traditional diameter is larger, waterflood injection rate is reduced, increased the thermal-arrest time of short copper pipe, improved the Heat-collecting effect of product;
4. the long copper pipe of thermal medium and the long copper pipe of cold medium are arranged at a side, facilitate the pipeline attaching of product, reduce the difficulty of later stage installing construction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the plate cored structure of a kind of flat plate collector of invention.
The specific embodiment
The invention provides a kind of plate cored structure of flat plate collector, as shown in Figure 1, plate cored structure is made up of with the parallel each other short copper pipe 4 of plural number the long copper pipe 1 of two ends shutoff, the long copper pipe 2 of thermal medium of one end shutoff, the long copper pipe 3 of cold medium of one end shutoff, and wherein plural short copper pipe 4 is divided into the short copper pipe 41 of thermal medium and the short copper pipe 42 of cold medium; Long copper pipe 1 is arranged at plural short copper pipe 4 one sides, and the long copper pipe 2 of thermal medium and the long copper pipe 3 of cold medium are all arranged at the opposite side of plural short copper pipe 4, facilitates the later stage pipeline installing of product; Long copper pipe 1 welds mutually with whole plural short copper pipes 4 and is inner unimpeded; The long copper pipe 2 of thermal medium welds mutually with the short copper pipe 41 of thermal medium and is inner unimpeded; The long copper pipe 3 of cold medium welds mutually with the short copper pipe 42 of cold medium and is inner unimpeded; The short copper pipe 41 of thermal medium is shorter than the short copper pipe 42 of cold medium, and the long copper pipe 2 of thermal medium is less than the long copper pipe 3 of cold medium to the distance between long copper pipe 1 to the distance between long copper pipe 1, and the long copper pipe 2 of thermal medium is parallel to the long copper pipe 3 of cold medium.
Wherein, preferred plate cored structure is provided with eight short copper pipes 4, and wherein four be the short copper pipe 41 of thermal medium, and other four is the short copper pipe 42 of cold medium, and short copper pipe 4 negligible amounts can reduce the quality of product, the cost of reduction product.
In addition, the caliber of long copper pipe 1, the long copper pipe 2 of thermal medium and the long copper pipe 3 of cold medium is 8mm, the caliber of short copper pipe 4 is 22mm, short copper pipe adopts the tubing of Large Diameter Pipeline, makes the Heat-collecting effect of short copper pipe more obvious, and inlet/outlet pipe adopts small-bore long copper pipe simultaneously, control the turnover water yield, make into water thermal-arrest fully, increase the thermal-arrest time of water inlet, optimized the performance of product.
Below use principle and the process of the plate cored structure of a kind of flat plate collector of the present invention:
As shown in the direction of arrow in Fig. 1, the direction of arrow is water (flow) direction, water carries out water filling from the long copper pipe of cold medium, water enters the long copper pipe that enters two ends shutoff after the short copper pipe of cold medium, then enter the short copper pipe of thermal medium from the long copper pipe of two ends shutoff, finally from the short copper pipe of thermal medium to the long copper pipe water outlet of thermal medium, wherein, short copper pipe place is thermal-arrest state, and the short copper pipe of cold medium and the short copper pipe of thermal medium all have insulation effect simultaneously.In the time carrying out water filling, because the bore of long copper pipe is less, so waterflood injection rate has obtained effective control, in short copper pipe, water speed is lower, and the thermal-arrest time increases, and has improved the Heat-collecting effect of product.
