Abstract: A fluid control assembly is provided, which includes a heat exchange core, a mounting block and a valve core member. At least a part of the valve core member is arranged in a first mounting hole passage of the mounting block, and the valve core member is sealable to a wall portion of the first mounting hole passage. In this way, the fluid control assembly includes a fluid flow passage that includes a first port, a second hole passage, a first hole passage, a first sub-passage, a communication hole, a second sub-passage, and a second port. A core body of the valve core member is operated under a pressure difference between the first sub-passage and the second sub-passage, to communicate or block the first sub-passage and the second sub-passage, to realize a constant flow direction of the fluid flow passage of the fluid control assembly.

Abstract: A plate heat exchanger is provided in the present application, which includes multiple first plates and multiple second plates which are alternately stacked together, first flow passages and second flow passages spaced from each other are formed between the first plates and the second plates, a first passage is formed by first orifices, a second passage is formed by second orifices, and the first passage and the second passage are in communication with each other via the first flow passages or the second flow passages to form a first fluid passage. At least one damping structure is provided in the first fluid passage, and at least a part of the first fluid passage is in communication with a first pipe or a second pipe via the damping structure.

Abstract: A heat exchange device includes a heat exchanger and a mounting plate for fixing the heat exchange device, and includes first and second flow passages which are not in communication with each other. The mounting plate includes a communication hole, a protruding portion and a mounting hole. The protruding portion protrudes outwards from the front side of the mounting plate. The mounting hole extends through the protruding portion and the mounting plate and includes a valve core receiving cavity. The valve core receiving cavity is in communication with the communication hole via a connection groove at a back side of the mounting plate; the mounting plate is fixed to the heat exchanger in a sealed manner, the mounting hole is in communication with the first flow passage, and the communication hole is in communication with the first flow passage via the connection groove and the mounting hole.

Abstract: A heat exchanger includes a first header pipe, a second header pipe, a third header pipe, a fourth header pipe and a plurality of flat tubes, the first header pipe is provided with a first space and a second space and a communicating passage for communicating the first space with the second space; when refrigerant flows from the first space of the first header pipe to the second header pipe along the flat tubes, a part of the refrigerant passes through the communicating passage and directly enters into the second space of the first header pipe, thus an overall flow resistance of the heat exchanger may be decreased to some extent. Besides, the flow quantity of the refrigerant in the third flow path is constant, however fluid state parameters may change, which may greatly improve the heat exchange capacity of the third flow path, thereby improving the heat exchange performance of the heat exchanger on the whole.
