A collector tube for a heat exchanger having at least one flat tube, may include a base and a cover arranged opposite the base. The base and the cover may define a longitudinal duct. The base may include at least one passage having an opening configured to accommodate the at least one flat tube of the heat exchanger. The opening may have at least one wide edge and at least one narrow edge. The longitudinal duct may have, in a cross section, a diameter that is smaller than the at least one wide edge of the opening. The at least one passage may include a collar extending away from the longitudinal duct.

A throttling heat exchange assembly includes a first heat exchange part, a bridge, a second heat exchange part, a throttling element, and a sensing element. The bridge is at least partially located between the first heat exchange part and the second heat exchange part. The bridge includes two holes and/or slots for communication facing towards the first heat exchange part. The bridge includes at least two holes or slots that allow communication with the second heat exchange part. The bridge is further provided with a first mounting part. The sensing element is fitted to the first mounting part. A sensing head of the sensing element is located in an internal space of the bridge.

A heat exchanger includes heat exchanger cores connected to a distributor. The inside of the distributor is divided into refrigerant flow paths, allowing the refrigerant to flow from one of the refrigerant flow paths to another one of the refrigerant flow paths. The heat transfer tubes of one of the heat exchanger cores disposed on a windward side of a flow of the air fed to the heat exchanger are connected to at least one of the refrigerant flow paths disposed in the distributor on an upstream side of a flow of the refrigerant. The heat transfer tubes of one of the heat exchanger cores disposed on a leeward side of the flow of the air fed to the heat exchanger are connected to at least one of the refrigerant flow paths disposed in the distributor on a downstream side of the flow of the refrigerant.

The invention relates to a heat exchanger, in particular for the refrigerant circuit of a motor vehicle. The heat exchanger is formed of interconnected rectangular plates. Channels are formed between the plates. Two heat exchanging media flow alternately through the channels formed in this way via at least one inflow opening and at least one outflow opening. The plates have profiles. Contact points are formed between the plates. The plates are connected to each other at said contact points. Flow paths of the two media from the corresponding inflow port to the corresponding outflow port are formed in this way. The flow has a main flow direction. The profiles of the plates as well as their contact points are shown such that the profiles run essentially along the main flow direction of the flow formed between the plates.

A vehicle condenser in which a notch portion of each coupling part of a pair of supports installed at the outermost sides of radiation fins extends so as to have a certain length from the tip of a body part to the inside end of the notch portion, or a through-hole is formed so as to be spaced by a predetermined distance toward the inside of the body part from the tip thereof, thereby preventing the radiation fins from melting when the clad on a header of a header tank is melted during the brazing of the radiation fins and flows along an embossing part, regardless of a method for manufacturing the supports. Consequently, it is possible to reduce the failure rate of the condenser and increase the efficiency of the condenser by maintaining the original state of the radiation fins.

A vehicle having a heating and cooling system includes a refrigerant loop for conveying refrigerant, a coolant loop for conveying coolant, a chiller configured to convey the refrigerant and the coolant, and a vessel coupled to the chiller and having a phase change material disposed therein. The phase change material is configured to freeze via heat transfer from the phase change material to the refrigerant and melt via heat transfer from the coolant to the phase change material.

A heat exchanger module with a first block of a first heat exchanger, further with a second block of a second heat exchanger, and further with an expansion valve, wherein the first block, the second block and the expansion valve are designed as an interconnected module.

A vehicle air conditioning system provides a heat exchanger and a vehicle air conditioning system comprising same, which can simplify the overall structure and can easily perform cooling/heating of air for air conditioning and dehumidification heating by using an integrated heat exchanger which is selectively supplied with low- and high-temperature cooling water by a supply valve to perform heat exchange.

A heat exchanger having an optimum design considering a thermal capacity of an end portion of an extrusion tube to significantly improve heat transfer performance by optimizing a shape and a thickness of the end portion of the tube, and a heat exchanger having an optimum design obtained based on a structured rule to enable easy application to other tubes with various dimensions. The heat exchanger has an end portion of a tube has a cross section in a quadrangular shape with rounded corners, each having a radius in a range of 15% to 45% of a height of the tube.
