The liquid storage part 102 is located at the end face 1012 of the plate heat exchanger assembly 101, and the connecting part 103 is located at the side face 1011 of the plate heat exchanger assembly 101. In this embodiment, the end face 1012 of the plate heat exchanger assembly refers to the corresponding position of the uppermost or lowermost plate of the plate heat exchanger assembly. The side face 1011 of the plate heat exchanger assembly is the face formed along the stacking direction of the plates. The plate heat exchanger assembly 101 is welded as a whole. The connecting part 103 is fixedly connected to the plate heat exchanger assembly 101. The liquid storage part 102 is a whole. The liquid storage part 102 is fixedly connected to the connecting part 103. The mounting bracket 104 includes a hoop 91 and a bracket part 92. In this embodiment, the mounting bracket 104 is an injection molding part. The hoop 91 and the bracket part 92 are integrally injection molded. The injection molding material has a certain strength, which can be the same as the material of other brackets used in vehicles. This is conducive to reducing the overall weight. The hoop 91 and the bracket part 92 both have multiple reinforcing ribs 912, which are conducive to further improving the strength of the mounting bracket. The hoop 91 is located in the circumferential direction of the liquid storage part 102 and tightly fits the outer circumferential surface of the liquid storage part 102.
