Fig. 2 andFig. 3 , in the embodiment, the plate heat exchanger 20 includes three firstfluid guide plates 21, two secondfluid guide plates 22 and four stoppingmembers 23. However, the quantities of the above components are not limited by the exemplary numbers. When the firstfluid guide plates 21, the secondfluid guide plates 22 and the stoppingmembers 23 are assembled, each of the first stoppingmembers 23, each of the firstfluid guide plates 23 and each of the secondfluid guide plates 22 jointly form a heat exchanging space. As such, from thefirst input pipe 24 towards the fourfluid sealing members 28, the firstfluid guide plates 21, the secondfluid guide plates 22 and the stoppingmembers 23 sequentially from afirst heating space 30, a secondheat exchanging space 40, a thirdheat exchanging space 50 and a fourthheat exchanging space 60, as shown inFig. 3 . Further, when the firstfluid guide plates 21, the secondfluid guide plates 22 and the stoppingmembers 23 are assembled, the firstfluid openings 214 respectively correspond to the secondfluid openings 224. Further, each of the stoppingmembers 23 allows only two of theheat exchanging spaces fluid openings 214 and two of the secondfluid openings 224, while the other twofirst fluid openings 214 and the other twosecond fluid openings 224 are separated. As such, one of the firstfluid openings 214 and the one correspondingsecond fluid opening 224 form afluid entrance 70 at one end, while the other firstfluid opening 214 and the other secondfluid opening 224 form afluid exit 80 at the other end. In other words, in the embodiment, the plate heat exchanger 20 includes fourfluid entrances 70 and four fluid exits 80. Further, the firstheat exchanging portions 213 of each of the firstfluid guide plates 21 and the secondheat exchanging portions 223 of each of thesecond fluid plates 22 are in a staggered arrangement, as shown inFig. 4 . - Referring to
Fig. 2 andFig. 3 , when thefirst input pipe 24 transports thefirst fluid 100, thefirst fluid 100 passes through one of the fluid entrances 70 to enter the firstheat exchanging space 30. In addition to entering the firstheat exchanging space 30, thefirst fluid 100 also continues flowing towards one of the secondfluid openings 224 of the adjacentfluid guide plate 22. At this point, being stopped by one of the stoppingmembers 23, thefirst fluid 100 is prohibited from entering the secondheat exchanging space 40. Next, thefirst fluid 100 continues flowing towards one of the firstfluid openings 214 of one of the firstfluid guide plates 21, and passes through anotherfluid entrance 70 to enter the thirdheat exchanging space 50. Similar to the above traveling method, thesecond fluid 101 passes through thesecond input pipe 26 to sequentially enter the secondheat exchanging space 40 and the fourthheat exchanging space 60. Therefore, thefirst fluid 100 and thesecond fluid 101 respectively enter the adjacentheat exchanging spaces heat exchanging spaces first fluid 100 and thesecond fluid 101 pass between the firstheat exchanging portions 213 and the secondheat exchanging portions 223 to further form a longitudinal vortex between the firstheat exchanging portions 213 and the secondheat exchanging portions 223. Meanwhile, the longitudinal vortex formed by the firstheat exchanging portions 213 and the secondheat exchanging portions 223 may vigorously stir thefirst fluid 100 and thesecond fluid 101 in theheat exchanging spaces first fluid 100 and thesecond fluid 101 such that temperatures in theheat exchanging spaces first fluid 100 and thesecond fluid 101. After heat exchange is performed between thefirst fluid 100 and thesecond fluid 101, thefirst fluid 100 and thesecond fluid 101 exit theheat exchanging spaces first fluid 100 and thesecond fluid 101 are respectively outputted via thefirst output pipe 25 and thesecond output pipe 27. In the embodiment, preferably, thefirst fluid 100 and thesecond fluid 101 enter theheat exchanging spaces - In the embodiment, the fluid entrances 70 are parallel to the fluid exits 80. For example, assume that a connecting direction between the
fluid entrance 70 and thefluid exit 80 of the firstheat exchanging space 30 is parallel to a connecting direction between thefluid entrance 70 and thefluid exit 80 of the secondheat exchanging space 40. Input and output directions along which thefirst fluid 100 and thesecond fluid 101 travel from the fluid entrances 70 to the fluid exits 80 are parallel to the connecting direction. Referring toFig. 4 andFig. 5 , each of the firstheat exchanging portions 213 and the secondheat exchanging portions 223 has a right hexagonal planar contour, and any two opposite sides of each of the firstheat exchanging portions 213 and any two sides of each of the secondheat exchanging portions 223 are parallel to the connecting direction. In other words, each of theheat exchanging portions 213 has six vertices, and a connecting direction of two opposite vertices is parallel to the connecting direction. The secondheat exchanging portions 223 are similarly configured. It should be noted that, configuration orientations of the firstheat exchanging portions 213 and the secondheat exchanging portions 223 are not limited to the above example. - In the embodiment, the first
heat exchanging portions 213 are arranged in a quantity of seven.Fig. 6 shows a diagram of data of channel pressure distributions of a high theta plate H, a low theta plate L, and the firstfluid guide plate 21 of the present invention. For the firstfluid guide plate 21 of the present invention, thevalue 1 on the horizontal axis represents the pressure of the firstheat exchanging portion 213 at the first row minus the pressure of the firstheat exchanging portion 213 at the second row, thevalue 2 represents the pressure of the firstheat exchanging portion 213 at the third row minus the pressure of the firstheat exchanging portion 213 at the fourth row, and so forth. In other words, thevalue 1 represents the channel pressure between the first row and the second row. Further, the left side of the horizontal axis represents the fluid input end, and the right side of the horizontal axis represents the fluid output end. In overall, the pressure drop of thefluid guide plate 21 is similarly to that of the conventional low theta plate L. - In the embodiment, the
first fluid 100 may be hot water, and thesecond fluid 101 may be cold water. Further, thefirst fluid 100 sequentially enters the firstheat exchanging space 30 and the thirdheat exchanging space 50, and thesecond fluid 101 sequentially enters the fourthheat exchanging space 60 and the secondheat exchanging space 40. Referring toFig. 7 , for the firstfluid guide plate 21, thevalue 1 on the horizontal axis represents a heat transfer coefficient of the firstheat exchanging space 30, thevalue 2 represents a heat transfer of the secondheat exchanging space 40, and so forth. In overall, the heat transfer coefficient of the firstfluid guide plate 21 is similar to that of the conventional high theta plate H. - As demonstrated, the plate heat exchanger 20 of the present invention simultaneously provides advantages of the low pressure drop of the conventional low theta plate L and the high heat transfer coefficient of the conventional high theta plate H. That is to say, with the present invention, respective molds of the high theta plate H and the low theta plate L for respectively manufacturing the high theta plate H and the low theta plate L need not be at the same time manufactured. In other words, compared to the high theta plate H and the low theta plate L, the plate heat exchanger 20 of the present invention is capable of significantly reducing mold developments and lowering production costs.
- In conclusion, the present invention provides a fluid guide plate and an associated plate heat exchanger. The fluid guide plate includes a first heat exchanging surface, a second heat exchanging surface, and a plurality of heat exchanging portions formed by recessing the first heat exchanging surface towards the second heat exchanging surface and disposed in protrusion at the second heat exchanging surface. Each of the heat exchanging portions has a right hexagonal planar contour. The plate heat exchanger includes a plurality of the above fluid guide plates. The heat exchanging portions of adjacent fluid guide plates are in a staggered arrangement to form a channel system. Accordingly, the heat exchanging portions allow fluids to respectively vigorously flow to form a longitudinal vortex in the channel system, so as to further generate a strong turbulence for enhancing heat transfer efficiency and reducing pressure drops of the fluids. Further, the fluid guide plate of the present invention is capable of significantly reducing mold developments and lowering production costs.
