Description

Heat exchanger and refrigerating device Technical Field The present disclosure relates to a heat exchanger and a refrigeration apparatus. Background Conventionally, for example, as in a heat exchanger described in patent document 1 (japanese patent application laid-open No. 2022-043207), there has been proposed a technique of forming a header by stacking a plurality of plate-like members. Disclosure of Invention Technical problem to be solved by the invention As such a heat exchanger, there is a heat exchanger in which a gas header through which a refrigerant in a gaseous state flows and a liquid header through which a refrigerant in a liquid or gas-liquid two-phase state flows are arranged in a direction in which flat tubes are arranged. Here, the states of the refrigerant flowing in the gas header and the liquid header are different, and therefore, the required functions thereof are sometimes different, and the number of members constituting the gas header is sometimes different from the number of members constituting the liquid header. In this way, in the case where the number of members constituting the gas header is different from the number of members constituting the liquid header, the gas header and the liquid header are difficult to concentrate. Technical proposal adopted for solving the technical problems The heat exchanger of the first aspect includes a plurality of flat tubes and a header.

The gas header portion and the liquid header portion are aligned in a first direction. The header has one or more gas components, one or more liquid components, and a first component. The first member extends throughout the gas header and the liquid header. The first member forms a gas header with the gas member. The first member forms a liquid header with the liquid member. The first member integrates a first prescribed number of gas members and a second prescribed number of liquid members different from the first prescribed number. The heat exchanger can integrate the gas member and the liquid member by the first member even when the number of the gas member and the number of the liquid member are different. The heat exchanger according to the second aspect is the heat exchanger according to the first aspect, wherein the first member and the gas member are stacked in the second direction. The second direction is a direction in which the flat tubes extend. The first member and the liquid member are stacked in the second direction.

The second member has a plurality of first openings. The profile of the first opening has a portion overlapping the profile of the flat tube when viewed in the second direction. In this heat exchanger, when the flat tubes are inserted into the header, the flat tubes cannot pass through the first openings, so that the insertion positions of the flat tubes can be determined. The heat exchanger of the sixth aspect is the heat exchanger of the fifth aspect, wherein the one or more intermediate members further include a third member. The third member is laminated between the first member and the second member in the second direction. The third member has a plurality of second openings.
