The invention relates to a heat exchanger, said exchanger including a bundle of tubes (2), which enables an exchange of heat between a refrigerant circulating in said tubes (2) and an external airflow, and a first collector (4), said exchanger being configured so as to establish the serial circulation of the refrigerant among a first portion of said tubes (2) leading into a first portion (4a) of said first collector, said first collector (4), and a second portion of said tubes (2) leading into a second portion (4b) of said first collector (4). According to the invention, said first collector (4) includes a partition (12) configured to disrupt the circulation of the fluid between the first and second portions of said tubes (2). The invention is specifically for electric and/or hybrid motor vehicles.

The present invention relates to an integral heat exchanger including: a first heat exchange portion for performing the heat exchange of a first heat exchange medium with external air; a second heat exchange portion separated from the first heat exchange portion and performing the heat exchange of a second heat exchange medium with the first heat exchange medium; and a third heat exchange portion for introducing the second heat exchange medium passing through the second heat exchange portion and to perform the heat exchange of the introduced second heat exchange medium with external air, wherein the first to third heat exchange portions are formed in one body integrally to each other.

A refrigerant evaporator includes a first evaporation unit and a second evaporation unit disposed in series in a flow direction of fluid to be cooled by evaporating refrigerant. An intermediate tank portion through which refrigerant flows is connected to an outer surface of one tank portion of the first evaporation unit and an outer surface of one tank portion of the second evaporation unit. A tank external refrigerant space through which refrigerant flows is defined by an outer wall of the one tank portion of the first evaporation unit, an outer wall of the one tank portion of the second evaporation unit, and an outer wall of the intermediate tank portion.

A manifold for a heat exchanger includes a first tubular manifold part and a second tubular manifold part. The ends of the first and second manifold parts are connected through a baffle which is arranged to block tubular openings of the ends. The baffle substantially separates the ends of the first and second manifold parts.

An integrated heat exchanger in which a flow path, in which a first heat exchange medium flows, and a flow path, in which a second heat exchange medium flues, are separated by a baffle, and includes a support surface having a slope of which the height lowers toward the outside, and formed at a header portion coming in contact with a gasket baffle sealing part, and the gasket baffle sealing part formed in a shape corresponding to the support surface of a header such that the deformation of a gasket is prevented during coupling; and problems in which the gasket of a coupling part, at which the baffle is positioned, is non-uniformly compressed or the gasket is broken or separated from a designated position by means of force of the other direction is prevented.

A heat exchanger includes a plurality of members made of aluminum or aluminum alloy, and a bundling component. The bundling component includes a main body portion having an anchoring portion, and a band portion extending from the main body portion and having a section on an opposite side of a main body portion side anchored in the anchoring portion. The bundling component is made of aluminum or aluminum alloy. At least part of the bundling component and at least part of the plurality of members are secured to each other with a brazing material interposed between the parts.

A heat exchanger including a first header tank and a second header tank that are disposed to be spaced apart a predetermined distance in a height direction and a core part that is disposed between the first header tank and the second header tank and includes a plurality of tubes and fins, the first header tank including a first header plate, a first tank, and a first partition wall that divides a space formed by a combination of the first header plate and the first tank to form a plurality of flow paths, the first partition wall being provided with a main communication hole and an auxiliary communication hole, and an area ratio of the auxiliary communication hole being 3 to 7% of an area of the main communication hole.

A thermal control device has a thermal control device base, a connection block attached to the thermal control device and a tubing for a heat exchange fluid attached to the connection block. The tubing has a tubing extension axis and a tubing side wall. The connection block includes a connection block receiving section, which receives a part of the tubing side wall. The connection block is configured to facilitate heat exchange between the tubing side wall and the thermal control device.

The present invention relates to the heat exchanger 1 of refrigerant circuitry of an air-conditioning system for a vehicle, which enables a bidirectional pass flow. The air-conditioning system is configured to perform a combined operation of cooling device mode and heat pump mode, the heat exchanger 1 is formed in the form of a multi-pass, and the flow direction of a refrigerant varies depending on operation mode. The first heat exchanger 1 formed in the form of a multi-pass includes header pipes 2 and 3, flow paths assigned to respective passes, and means configured to partition an internal volume space of one or more header pipes 2 and 3 into independent regions. A first pass of the heat exchanger 1 has a greater flow cross section and greater heat exchange surface than the last pass.

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.
