Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention is described in detail.
The flat formula heat exchange unit of a kind of double helix is proposed in one embodiment of the present of invention.
Fig. 1 shows the structural representation of the flat formula heat exchange unit of double helix of the present invention.Fig. 2 shows the sectional view of the pipe heat pipe of the flat formula heat exchange unit of double helix of the present invention.
With reference to Fig. 1, the flat formula heat exchange unit of double helix of one embodiment of the present of invention specifically comprises:
Entrance 1, the helical disk be connected with described entrance is coiled into the heat exchanger tube 2 of tubular, and the outlet 3 be connected with another port of described heat exchanger tube.
In the present embodiment, heat exchanger tube 2 comprises the internal spiral cylinder and external spiral cylinder that are interconnected, and internal spiral cylinder and external spiral cylinder are arranged to have identical axis, thus can make the medium of heat exchanger tube outside can uniformly across heat exchanger tube 2.
In addition, heat exchanger tube 2 is flat tube structure, the form that cross section is rectangle as made, and is connected by arc-shaped transition on the both sides of rectangle.
In addition, the minor face that heat exchanger tube 2 also can make cross section as shown in Figure 2 relative with two by two relative long limits is formed, and long limit is straight line, and minor face is by interior arc outwardly.
In addition, in the present embodiment, above-mentioned flat structure by directly being formed through specific technique compacting by pipe, thus can prepare the heat exchanger tube of the present embodiment quickly and easily.
In the present embodiment, heat exchanger tube 2 inside is used for by first medium, outside by second medium, and second medium enters in the middle part of the spiral-tube of heat exchanger tube 2, and flows out from the gap between described internal spiral cylinder and the adjoining spiral pipe of described external spiral cylinder successively.
