Accompanying drawing explanation
Fig. 1 is the structural representation of the plate cored structure of invention flat plate collector.
Fig. 2 is the another kind of structural representation of the plate cored structure of invention flat plate collector.
The specific embodiment
The invention provides the plate cored structure of flat plate collector, as shown in Figure 1, especially, plate cored structure is made up of the short copper pipe 1 of plural number and two long copper pipes, wherein first long copper pipe 2 of sealing that long copper pipe is sealing two ends, second long copper pipe is open at both ends, middle-end is provided with the sector boss copper pipe 3 of block section 31, the both sides of the block section of second long copper pipe are respectively cold medium inlet tube 32 and thermal medium exit tube 33, two long copper pipes are arranged at the both sides of plural short copper pipe 1, two long copper pipes respectively with the equal vertical welding of the short copper pipe 1 of plural number, and two long copper pipes and plural short copper pipe 1 are inner unimpeded, wherein, the block section 31 of sector boss copper pipe 3 divides 1 point of short plural number copper pipe into two parts, the short copper pipe being connected with cold medium inlet tube 32 is the short copper pipe 11 of cold medium, the short copper pipe being connected with thermal medium exit tube 33 is the short copper pipe 12 of thermal medium.
Wherein, plate cored structure is provided with eight short copper pipes, and wherein four is the short copper pipe of thermal medium, and other four is the short copper pipe of cold medium, and short copper pipe negligible amounts can reduce the quality of product, reduces the cost of product.
As shown in Figure 2, for another kind of structure of the present invention, first long copper pipe 2 is an end closure, the other end is uncovered, and be connected also inner unimpeded with one the 3rd long copper pipe 4, one the 4th long copper pipe 5 is connected with second long copper pipe 3 and is inner unimpeded, between the 3rd long copper pipe and the 4th long copper pipe, is vertically welded with plural short copper pipe, and plural short copper pipe is all unimpeded with the 3rd long copper pipe and the 4th long copper pipe inside.Preferably, plate cored structure is provided with the short copper pipe of ten six roots of sensation, and wherein the short copper pipe of plural number between the 3rd long copper pipe and the 4th long copper pipe is the short copper pipe of thermal medium, can increase according to demand the quantity of the short copper pipe of thermal medium, meets the demand of product reservoir storage.
In addition, the caliber of long copper pipe is 8mm, the caliber of short copper pipe 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 flat plate collector of the present invention:
