Each supercharger 21 has one air outlet and one air inlet. The air inlet, the air outlet, the water outlet and the water inlet are shown by arrows in the figure.
As shown in fig. 1, each stage of heat exchanger 1 includes an air inlet, an air outlet, and an air outlet. Specifically, as shown in fig. 2, the heat exchanger 1 includes a housing (not shown), an end plate 11, a bottom plate 12, and two sets of plate bodies 13. The end plate 11 and the bottom plate 12 are oppositely arranged in the shell; two sets of plate bodies 13 are arranged between the end plate 11 and the bottom plate 12; wherein, the end plate 11, the bottom plate 12 and the plate body 13 are respectively provided with a first through hole and a second through hole, the cooling water channels are formed by all the first through holes, and the air flow channels are formed by all the second through holes. The heat exchanger 1 comprises a cooling water channel and an air flow channel, wherein the cooling water channel and the air flow channel are mutually isolated and are arranged in parallel.
In this embodiment, in order to improve the heat exchange efficiency, the plate body 13 is an aluminum plate, and grooves are rolled on the aluminum plate, and in order to distinguish the air flow channel and the cooling water channel, the two sets of plate bodies 13 are respectively defined as a first plate body 131 and a second plate body 132, and the first plate body 131 and the second plate body 132 are staggered. The groove of the first plate 131 rolled in the thickness direction is a first pressing groove 133, and a part of the first pressing groove 133 of the first plate 131 is communicated with the first through hole. The groove of the second plate 132 rolled in the thickness direction is a second pressing groove 134, and a part of the second pressing groove 134 of the second plate 132 is communicated with the second through hole. In particular, the first pressing groove 133, which is in communication with the cooling water channel, faces one side of the second plate 132, and the side of the second plate 132 is a flat surface, so that a sealed heat exchange channel is formed between the first pressing groove 133 and the second plate 132, and similarly, the second pressing groove 134, which is in communication with the air flow channel, faces one side of the first plate 131, and the side of the first plate 131 is a flat surface, so that a sealed heat exchange channel is also formed between the second pressing groove 134 and the first plate 131, so that in a practical structure, the first pressing groove 133 and the second pressing groove 134 need to be arranged in a staggered manner, as shown in fig. 3.
