Described is a stopper including a filtering unit housed in an interior of a liquid receiver main body through which a refrigerant passes, a fixed portion that includes a screw portion that is screwed into an inner peripheral face of the liquid receiver main body, a sealing member in contact with the inner peripheral face of the liquid receiver main body, thereby preventing a leakage of a refrigerant to the fixed portion, and a movable connection portion provided between the filtering unit and the fixed portion for linking the filtering unit to the fixed portion in such a way that the filtering unit is not caused to follow a rotation of the fixed portion, and in such a way that the filtering unit is caused to follow an axial direction movement of the fixed portion.

A receiver includes a large diameter main body portion, and an intermediate member side small diameter portion. A wall thickness of the intermediate member side small diameter portion is smaller than a wall thickness of the main body portion. As a result, heat capacity of the intermediate member side small diameter portion is reduced. As a result, it is possible to complete brazing between the intermediate member side small diameter portion and the intermediate member, at the same time as brazing among tanks, tubes, and fins. A desiccant enclosed in a flexible bag can be taken in and out through the intermediate member side small diameter portion.

To allow an end plate 5 on one side of a heat exchanger to support a liquid receiver 20 in a preferable manner, the present invention provides the following structure: The end plate 5 is formed to have a C-shaped cross section, having a pair of reinforcing ribs 18A, 18B protruding outward in the right-left direction from the front and back edges of the end plate 5. A fixing band 30 includes: an embracing portion 31 formed in a loop for embracing the liquid receiver 20; an attaching portion 32 (a pair of attaching pieces 32A, 32B) to the end plate 5, the attaching portion 32 being formed continuously with the embracing portion 31; and a reinforcing portion 33 formed integrally with the attaching portion 32 (attaching piece 32A) so as to be fitted between the pair of reinforcing ribs 18A, 18B.

A filter assembly for a plate heat exchanger comprising inlet and outlet ports for passage of a working medium and a cooling or heating fluid, respectively, wherein the filter assembly is dimensioned to fit into the inlet or outlet ports, wherein the filter assembly comprises a proximal flange and a distal flange and at least one filter tube attached at respective ends to the proximal flange and the distal flange, respectively, wherein the at least one filter tube is adapted to receive an elongated filter element and further comprises a plurality of inlet holes arranged on a circumferential surface thereof, and wherein the distal flange comprises at least one through-going outlet aperture in fluid communication with the interior of the at least one filter tube.

The present disclosure provides a refrigerant tank for storing a refrigerant circulating in a cooling circuit. The refrigerant tank includes a housing body and a desiccant bag. The housing body defines therein a space for storing the refrigerant. The desiccant bag houses a desiccant therein and is disposed inside the space of the housing body. The housing body includes a side surface defining an opening through which the refrigerant passes. The refrigerant tank further includes a contact preventing member that prevents the desiccant back from coming into contact with an edge of the opening.

A condenser has a core part having tubes, a first modulator tank and a second modulator tank. The first modulator tank is provided along a side portion of a header tank. The second modulator tank communicates with an interior of the first modulator tank and is provided along a lower edge of the core part in a gravity direction. An interior of the header tank is provided with a communicating space that communicates with the interior of the first modulator tank and an interior of the second modulator tank. The header tank has an introduction passage that guides liquid-phase refrigerant in the communicating space to a supercooling portion of the core part. A first connection part between the communicating space and the introduction passage is disposed on a lower side, in the gravity direction, of a second connection part between the communicating space and the second modulator tank.

A liquid receiver is composed of a tubular base member having open upper and lower ends, a tubular tank member having a closed upper end and an open lower end and joined to the base member, and a plug fitted into the base member. A female screw is provided on the inner circumferential surface of the base member, and refrigerant inflow and outflow holes are formed in a portion of the base member above the female screw such that the former is located above the latter. A male screw to be screwed into the female screw is provided on the outer circumferential surface of the plug to be located below the refrigerant outflow hole. Sealing is established between a portion of the inner circumferential surface of the base member located below the female screw and a portion of the outer circumferential surface of the plug located below the male screw.

A condenser includes a condensation section, a super-cooling section located above the condensation section, and a liquid receiver. The liquid receiver has a first space communicating with the condensation section through a refrigerant inlet and a second space located above the first space and communicating with the super-cooling section through a refrigerant outlet. A partition member is provided in the liquid receiver in order to divide the internal space of the liquid receive into the first space and the second space. A suction pipe which is open at upper and lower ends thereof and which establishes communication between the first space and the second space is disposed in the first space of the liquid receiver. The partition member has an internal volume adjustment portion for increasing the internal volume of the first space and decreasing the internal volume of the second space.

A fluid collector having a housing having a tubular circumferential wall with a first end face having a first opening and with a second end face having a second opening, which is situated opposite the first opening of the first end face, a first cover being provided, which closes the first opening on the first end face, and a second cover being provided, which closes the second opening on the second end face. The tubular circumferential wall has an area with an, in particular, planar connecting surface, on which at least one flange element is arranged and fastened as a connecting element, at least one bore or one channel being provided in the area having the connecting surface, which fluidically connects the interior of the housing to the at least one connecting element.

A liquid receiver of a condenser has a liquid receiver main body and a plug removably fitted thereinto. The liquid receiver main body has a refrigerant inflow hole into which refrigerant flows from a condensation section and a refrigerant outflow hole from which refrigerant flows into a supercooling section. The liquid receiver has a first space formed above the upper end of the plug and communicating with the refrigerant inflow hole and a second space formed below the upper end of the plug and communicating with the refrigerant outflow hole. The plug has a flow passage which is open to the first space and the second space at opposite ends. The first-space-side opening of the flow passage is located below the refrigerant inflow hole. The flow passage has a throttle portion whose cross-sectional area is smaller than a hole area of the refrigerant inflow hole.
