Detailed description of the invention
As shown in Figure 1, be the structural representation of an embodiment of heat exchanger according to the present invention.
In the present embodiment, described heat exchanger comprises end cap layers 1, interlayer 2 and bottom 3.
The center of described end cap layers 1 is provided with a liquid-inlet 11, be provided with to the bilateral symmetry of described liquid-inlet 11 first liquid outlet 121 and second liquid outlet 122, and laying respectively at the submarginal position of described end cap layers 1, described first liquid outlet 121 and second liquid outlet 122 are through to described bottom 3.Preferably, described liquid-inlet 11 and first liquid export 121 and second liquid export 122 on same straight line.By the region that the submarginal positions that first liquid outlet 121 and second liquid outlet 122 are arranged at described end cap layers 1 are to as often as possible flow through heat exchanger inside after making liquid enter from liquid-inlet 11, and then flow out from first liquid outlet 121 and second liquid outlet 122, so that it is more even to make bottom 3 be heated, improve heat exchange efficiency.About the flow path of liquid, hereafter can be described in detail.
Described interlayer 2 is provided with multiple aperture, is preferably rectangle, along the direction spread configuration perpendicular to liquid-inlet 11 and liquid outlet line, and be provided with first row aperture 211 and secondary series aperture 212 liang row symmetrically about liquid-inlet 11.First row aperture 211 and secondary series aperture 212 are arranged at the inner side of first liquid outlet 121 and second liquid outlet 122 respectively.The object arranging first row aperture 211 and secondary series aperture 212 about liquid-inlet 11 is symmetrically, liquid enters rear shunting by described liquid-inlet 11, enter bottom respectively by first row aperture 211 and secondary series aperture 212, the object done like this and the flow path of liquid hereafter can be described in detail.
Described bottom 3 is provided with S type dividing plate 31, and described bottom 3 is divided into the first groove 311 and the second groove 312 by described S type dividing plate 31.Aliging with described secondary series aperture 212 in one end of described first groove 311, aligns with described first row aperture 211 in one end of described second groove 312.Preferably, one end of described first groove 311 and the width of described secondary series aperture 212 are consistent, one end of described second groove 312 and the width of described first row aperture 211 are consistent, to guarantee that the liquid flowed out from a certain aperture can only enter the groove of its correspondence.As the further improvement to above-mentioned embodiment, be also all provided with a baffle plate 32 in described groove 311 and 312, form U-shaped passage in the trench, to increase heat exchange area.
As a modification of the embodiment above, the corner place of end cap layers 1, interlayer 2 and bottom 3 is also all respectively equipped with a fixing hole 4, utilizes fishbolt to pass described fixing hole 4 and clamps described end cap layers 1, interlayer 2 and bottom 3.
