Abstract
Disclosed is a heat exchanger. An end cover is assembled and fixed to a port of a first header in a lengthwise direction or a port of a second header in a lengthwise direction, and the end cover includes a body and a first opening formed in the body. The body includes a second cavity and a first recess. The first recess includes a first bottom wall close to the first opening, the first bottom wall is provided with a third opening, the third opening is in communication with the first opening and the second cavity, and the first opening is farther away from an inner cavity of the first header or an inner cavity of the second header than the second cavity. The open area of the first recess is larger than that of the third opening.
Claims21
A heat exchanger comprising a first header, a second header, heat exchange tubes, and an end cap,
- wherein each of the heat exchange tubes has an end connected to the first header and another end connected to the second header, an inner cavity of each of the heat exchange tubes communicates an inner cavity of the first header with an inner cavity of the second header, and each of the first header and the second header comprises two ports disposed in a length direction thereof;
- wherein the end cap is assembled and fixed to one port of the two ports of the first header or one port of the two ports of the second header, and the end cap comprises a body and a first opening formed in the body;
- wherein the body comprises a second cavity and a first groove portion, and the first groove portion is located between the first opening and the second cavity;
- wherein the first groove portion comprises a first bottom wall close to the first opening, the first bottom wall is provided with a third opening communicating the first opening with the second cavity, the second cavity is in communication with the inner cavity of the first header or the inner cavity of the second header, the first opening is located farther from the inner cavity of the first header or the inner cavity of the second header than the second cavity, and the first opening is configured for inflow or outflow of a refrigerant;
- wherein a width of the third opening in a transverse extension direction of the first bottom wall is smaller than a width of the first groove portion in the transverse extension direction of the first bottom wall;
- and
- wherein a flow area of the first groove portion is greater than a flow area of the third opening.
