Description
Technical field
The utility model relates to a kind of technology of field of heat exchangers, specifically a kind of Novel saw tooth form offset strip fin.
Background technology
Conventional heat-exchanger fin is all a thin plate by punch forming, forms the identical tooth of several rows of structure, often
Toothrow forms fluid channel by the windowing of male-female arrangement.Windowing for fixed width, heat dissipation area and aisle spare are one
Fixed, it is difficult to meet the heat exchange demand under different situations.
Utility model content
The utility model is directed to deficiencies of the prior art, it is proposed that a kind of Novel saw tooth form offset strip fin,
The secondary windowing piece of main windowing on piece superposition of zigzag offset strip fin, can increase the heat dissipation area of fin.
The utility model is achieved through the following technical solutions：
The utility model includes the main windowing piece of several zigzag of stagger arrangement setting, is formed by drawing quality steel sheet；Described
Tooth-shape structure includes top plate and the both side plate that is connected with top plate, and two adjacent tooth-shape structures of the same main windowing on piece of zigzag are logical
Bottom plate is crossed to be connected；
The tooth-shape structure is provided with secondary windowing piece, and one end of the secondary windowing piece is connected with tooth-shape structure side plate.
The other end of the secondary windowing piece is connected with bottom plate or top plate.
Preferably, the secondary windowing piece both ends are connected using rounded structure with tooth-shape structure side plate, top plate or bottom plate.
Preferably, the both side plate of the tooth-shape structure is equipped with secondary windowing piece；On the both side plate of the same tooth-shape structure
The windowing direction of pair windowing piece is identical.
The windowing direction of the main windowing on piece of two zigzag being disposed adjacent, pair windowing piece is opposite.
The width of each secondary windowing piece is no more than the half of the main windowing piece width of zigzag, the height of each secondary windowing piece
Half of the degree no more than tooth-shape structure height.
Technique effect
Compared with prior art, the utility model increases heat dissipation area by being superimposed secondary windowing piece in main windowing on piece；
In fluid flow direction under windowing on piece tooth-shape structure orientation unanimous circumstances, increased while increasing heat dissipation area
Aisle spare；In the case where fluid flow direction is vertical with windowing on piece tooth-shape structure orientation, increase heat dissipation area
Better turbulent flow effect is played to fluid simultaneously.

Specific implementation mode
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Embodiment 1
As shown in Figure 1, the present embodiment includes the main windowing piece of several zigzag of stagger arrangement setting, pass through drawing quality steel sheet shape
At.
Preferably, the main windowing piece of the zigzag includes identical first main windowing piece, the 1 and second main windowing of structure width
Piece 2, the 1 and second main windowing piece 2 of the first main windowing piece are staggered on fin.
Preferably, the described first main windowing piece 1 is equipped with secondary windowing piece on tooth-shape structure both side plate, including externally protrudes out in tooth
The the first secondary windowing piece 11 and indent of shape structure are in the second secondary windowing piece 12 of tooth-shape structure, wherein the first secondary windowing piece 11 with
Bottom plate is connected, and the second secondary windowing piece 12 is connected with top plate；
Preferably, the described second main windowing piece 2 is equipped with secondary windowing piece on tooth-shape structure both side plate, including indent is in tooth
The third pair windowing piece 21 of shape structure and the fourth officer windowing piece 22 for externally protruding out in tooth-shape structure, third pair windowing piece 21 and top plate phase
Even, fourth officer windowing piece 22 is connected with bottom plate；
On the main 1 and second main windowing piece 2 of windowing piece of first be disposed adjacent, adjacent tooth-shape structure upwards is arranged in fin
The secondary windowing direction of same side plate is opposite.
Preferably, the size of the described first secondary windowing piece 11 and third pair windowing piece 21 is identical, highly for tooth it is high one
Half, the one third for the piece width that opens a window based on width.
Preferably, the size of the described second secondary windowing piece 12 and fourth officer windowing piece 22 is identical, highly for tooth it is high one
Half, the one third for the piece width that opens a window based on width.
The present embodiment is related to a kind of plate-fin heat exchanger, including several zigzag offset strip fins being stacked, institute
The flank of tooth for stating zigzag offset strip fin bumps is welded with upper and lower heat exchange chip 3 respectively, as shown in Figure 2；Two pieces be disposed adjacent
The windowing direction of zigzag offset strip fin is vertical.
As shown in figure 3, fluid flow direction is under windowing on piece tooth-shape structure orientation unanimous circumstances, fluid is from main windowing
The second flow channel 5 formed between piece flows through, while the third flow channel 6 also formed from secondary windowing piece in main windowing on piece flows through；It is secondary
The third flow channel 6 that windowing piece is formed in main windowing on piece considerably increases the aisle spare of fin, reduces the resistance of fluid, simultaneously
Also increase the heat dissipation area of fin.
As shown in Figure 2 and Figure 4, in the case that fluid flow direction is vertical with windowing on piece tooth-shape structure orientation, fluid stream
Overheat the first flow 4 and second flow channel 5 that exchange chip 3 is formed with fin；Although on the other hand third flow channel 6 reduces the
The flow area of two runners 5, but secondary windowing piece plays better action of turbulent flow to fluid.
