A heat exchanging module (1) comprising a heat exchanger (2) and a bottle (6), the bottle (6) being attached to the heat exchanger (2) at one first longitudinal end (63) of the bottle (6), said heat exchanging module (1) comprising at least one attachment mean (10) located at a second longitudinal end (64) of the bottle (6), said attachment mean (10) restricting at least one axial movement of the bottle (6) along a longitudinal dimension (5) of said bottle (6).

The invention concerns an attachment device (3) for a heat exchanger (2) comprising a core (23) for exchanging heat between a first fluid and a second fluid, said core (23) being provided with collectors (21) for the first fluid, said exchanger (2) comprising a cylinder (25), said cylinder (25) and one of said collectors (21) allowing the passage of said first fluid from one to the other, said attachment device (3) comprising a body, which is set up in order to close said cylinder (25), and an extension which allows the core (23) to be secured to a holder (4).

The invention also concerns a cylinder (25) which comprises such an attachment device (3), a heat exchanger (2) which comprises such a cylinder (25) and a heat exchanging module which comprises such a heat exchanger (2).

A heat exchanging module includes a heat exchanger, a frame, and a bottle. The heat exchanger may be attached to the frame. The bottle may be attached to the heat exchanger by a first attachment mean at a first portion of the bottle. Additionally, the bottle may be attached to the frame with a second attachment mean located at a second portion of the bottle.

An accumulator, including a housing and a cover body, one end of the housing being open; the housing is internally provided with an accommodating cavity, the accommodating cavity being internally provided with a filter; a peripheral wall of the housing comprises a first thick wall part, the first thick wall part being provided with an inlet channel, and one end of the inlet channel communicating with the accommodating cavity, while the other end of the inlet channel communicates with the outside; one end of an outlet channel communicates with the accommodating cavity by means of the filter, while the other end of the outlet channel communicates with an outer portion of the housing. The accumulator may be directly welded and fixed to a heat exchange core without requiring a pipeline connection, the risk of external leakage being small, and the anti-seismic performance being high.

A water-cooling type condenser having a core part having a refrigerant fluid channel wherein a refrigerant flows and a cooling water fluid channel wherein cooling water flows; a gas-liquid separator disposed spaced apart from one side of the core part; a penetration connector having communication holes passing through both sides thereof, one side thereof being inserted into and coupled to a refrigerant outlet formed on the core part, and the other side being inserted into and coupled to a refrigerant inlet formed on the gas-liquid separator. A non-penetration connector is blocked between both sides thereof. One side is inserted into and coupled to a coupling hole formed on the core part, and the other side is inserted into and coupled to a coupling hole formed on the gas-liquid separator. The gas-liquid separator and the refrigerant fluid channel communicate. The gas-liquid separator is fixed to the core part.

A heat exchanger includes: a gas-refrigerant pipe; a header connected to the gas-refrigerant pipe; and heat transfer tubes connected to the header. The header includes: a first plate member; and a second plate member that is stacked on the first plate member in a plate-thickness direction. The first plate member includes a first opening that constitutes an internal space of the header. The second plate member includes a second opening that, together with the first opening, constitutes the internal space of the header. The internal space of the header communicates with the heat transfer tubes. A first direction is perpendicular to both the plate-thickness direction and a direction in which the heat transfer tubes are arranged. A width of a part of the first opening in the first direction is different from a width of the second opening in the first direction.

The present invention relates to a water-cooling type condenser, and more specifically, to a water-cooling type condenser including a fixing plate for fixing a gas and liquid separator, wherein the fixing plate is formed to enable a refrigerant and cooling water to flow by means of coupling between first and second plate portions, and is integrally formed, by brazing, with remaining components (a plate, a first inlet pipe, a first outlet pipe, a second inlet pipe, and a second outlet pipe), so as to enhance assemblability and durability and enable size reduction.
