DETAILED DESCRIPTION OF THE INVENTION A heat exchange module in accordance with a preferred embodiment of the present invention will now be described with reference to the accompanying drawings, wherein like reference numerals will be used.

[0017]

1A is an exploded perspective view of a heat exchange module according to a first embodiment of the present invention, and FIG. 1B is a partial cross-sectional view of the heat exchange module shown in FIG. 1A. Referring to FIG. 1A and FIG. 1B simultaneously, the heat exchange module 1 is used for heat exchange between two fluids, and the fluid may include a liquid, a gas, or a mixture of a liquid and a gas. The heat exchange module 1 includes a first cover 11 , a second cover 12 , and a plurality of plates 13 . The first cover 11 is disposed opposite to the second cover 12, and the plate 13 is disposed between the first cover 11 and the second cover 12.

[0018]

In the present embodiment, the first cover 11 has a first fluid inlet 111, a first fluid outlet 112, a second fluid inlet 113, and a second fluid outlet 114. The plates 13 have two first fluid openings 131 and two second fluid openings 132, respectively. Here, the first fluid will flow in through the first fluid inlet 111 and flow through the flow path formed between each of the first fluid openings 131 and the plate member 13 and then flow out from the first fluid outlet 112. Similarly, the second fluid will flow in through the second fluid inlet 113 and flow through the second fluid outlet 114 after flowing through the second fluid opening 132 and another flow path formed between the plates 13. Among them, the two flow paths are not connected.

[0019]

In the present embodiment, the shape of the portion of the first fluid opening 131a or the second fluid opening 132a is different from the shape of the other first fluid opening 131 or the second fluid opening 132. As such, when the first fluid or the second fluid flows from the first fluid opening 131 or the second fluid opening 132 through the first fluid opening 131a or the second fluid opening 132a having different aperture shapes, the fluid will be more evenly distributed. In the flow channel to improve heat exchange efficiency. The shape of the other first fluid opening 131 or the second fluid opening 132 in this embodiment is exemplified by a circle, and the shape of a part of the first fluid opening 131a or the second fluid opening 132a is exemplified by a semicircle. In some embodiments, the first fluid opening 131a or the second fluid opening 132a may of course also be square, triangular, elliptical, or other polygonal shape, and the like. Further, the present invention does not limit the shapes of the first fluid openings 131, 131a or the second fluid openings 132, 132a as long as the shapes thereof are different.

[0020]

Further, in some embodiments, the aperture of the portion of the first fluid opening 131a or the second fluid opening 132a may be smaller than the apertures of the other first fluid opening 131 or the second fluid opening 132. In this way, when the first fluid or the second fluid flows from the normal-sized first fluid opening 131 or the second fluid opening 132 through the first aperture opening 131a or the second fluid opening 132a having a smaller aperture, the fluid can be evenly distributed. The ground is distributed in the flow channel to improve heat exchange efficiency. In practice, the manner of reducing the first fluid opening 131a or the second fluid opening 132a may be, for example, reducing the opening radius or designing the original circular opening as a semi-circular opening. The opening area of the fluid opening 131a or the second fluid opening 132a may be smaller than the opening area of the original first fluid opening 131 or the second fluid opening 132, and the present invention is not limited thereto.

[0021]

In this embodiment, the first cover 11 has two opposite long sides and two opposite short sides. The first fluid inlet 111 and the second fluid outlet 114 are disposed adjacent to each other, for example, along a short side, and the second fluid inlet 113 and the first fluid outlet 112 are also disposed adjacent to each other, for example, along another short side. . Further, the first fluid inlet 111 is disposed opposite the first fluid outlet 112, and the second fluid inlet 113 and the second fluid outlet 114 are also disposed opposite each other.

[0022]

In some embodiments, the projection of the first fluid opening 131 or the second fluid opening 132 to the first cover plate 11 can be at least partially located on a projection surface of the first fluid inlet 111 or the second fluid inlet 113. That is, the first fluid opening 131 or the second fluid opening 132 is in partial communication with the opening of the first fluid inlet 111 or the second fluid inlet 113.

[0023]

Further, in the present embodiment, the first fluid opening 131a or the second fluid opening 132a whose opening shape is different from the other first fluid opening 131 or second fluid opening 132 is exemplified by the following semicircular opening. In some embodiments, such as the heat exchange module 1a shown in FIG. 2A, the first fluid opening 131b or the second fluid opening 132b is an upper semicircular opening. Alternatively, as shown in FIG. 2B, the first fluid opening 131c or the second fluid opening 132c may be an opening in which the upper and lower semicircles are alternately arranged. As a result, when the fluid flows into the heat exchange modules 1a, 1b, it will be more evenly distributed in the flow path to improve heat exchange efficiency.

[0024]

3 is a schematic diagram of a heat exchange module according to a second embodiment of the present invention. Referring to FIG. 3 , the heat exchange module 2 also includes a first cover 21 , a second cover 22 , and a plurality of plates 23 . Similarly, the first cover plate 21 has a first fluid inlet 211, a first fluid outlet 212, a second fluid inlet (not shown), and a second fluid outlet (not shown). The plate member 23 has two first fluid openings 231 and two second fluid openings (not shown). In this embodiment, the heat exchange module 2 further includes at least one baffle 24 disposed between the plates 23 and shielding the first fluid openings 231 or portions of the second fluid openings. The shape of the portions of the first fluid openings 231a or the second fluid openings is different from the shapes of the other first fluid openings 231 or the second fluid openings. Thus, in the present embodiment, by the design of the portion of the first fluid opening 231 or the second fluid opening that the baffle 24 shields, the fluid can also be uniformly distributed in the flow path to improve heat exchange efficiency.

[0025]

In addition, in other embodiments, in addition to the baffle 24, the heat exchange module 2 may also adjust the aperture shape or size of the portion of the first fluid opening 231a or the second fluid opening 232a as in the first embodiment. That is, the heat exchange module 2 can simultaneously set the shape or size of the fluid opening of the baffle 24 and the adjustment plate member 23 to evenly distribute the fluid in the flow channel to improve heat exchange efficiency.

[0026]

In summary, the heat exchange module of the present invention can distribute the fluid evenly in the flow channel by the aperture of the portion of the first fluid opening or the second fluid opening being smaller than the apertures of the other first fluid opening or the second fluid opening. To improve heat exchange efficiency.
