A heat exchanger includes: a gas-side port connected to piping for a gaseous refrigerant; a liquid-side port connected to piping for a liquid refrigerant; a refrigerant path that links the gas-side port to the liquid-side port; at least four heat exchange part regions that perform heat exchange between air and the refrigerant flowing through the refrigerant path; and a branching and merging part that branches and merges the refrigerant path to connect the heat exchange part regions in series between the gas-side port and the liquid-side port through the refrigerant path. The heat exchange part regions are connected to each other through the branching and merging part so as to allow the number of refrigerant paths provided in the heat exchange part region near the gas-side port to be greater than the number of refrigerant paths provided in the heat exchange part region near the liquid-side port

A heat exchanger is formed by a plurality of heat exchanger units each including a respective small tank at each end of a core, the units being stacked in a thickness direction of the cores, and oil is supplied to finned tubes constituting the core of each of the units via a header. Each of the tanks has an opening for communicating with the header which opening is at a position on the length of the tank different from that of each of the adjacent tanks.

A thermal regulation device for cooling electrical energy storage members, the thermal regulation device including a tube that is configured to be in contact with the electrical energy storage members and that includes at least one channel for circulating heat transfer fluid, a collecting tank that is disposed at one end of the tube and that includes collecting chambers that fluidically communicate with the at least one circulation channel of the tube, and at least two connecting sleeves disposed on either side of the collecting tank and configured to communicate with the same collecting chamber, the connecting sleeves having shapes that are distinct from one another.

According to one embodiment, a heat exchanger includes a pipe through which a fluid flows, and a supply device that supplies the fluid to the pipe. The pipe includes a flexible part deformed by flowing of the fluid, and a constricted part located at a downstream side of the flexible part along a flow direction of the fluid.

A heat dissipation device assembly includes an aluminum base seat, an aluminum radiating fin assembly and at least one U-shaped copper heat pipe, which is upright arranged or horizontally arranged. The aluminum base seat has at least one connection section. A copper embedding layer is disposed on the connection section. The aluminum radiating fin assembly is assembled and disposed on the aluminum base seat. The copper heat pipe has a heat dissipation section and a heat absorption section respectively connected on the aluminum radiating fin assembly and the connection section of the aluminum base seat. By means of the copper embedding layer, the aluminum base seat and the copper heat pipe can be directly welded and connected with each other without chemical nickel treatment.

The disclosure provides a connecting tube and a heat exchanger. The connecting tube is configured to be connected with flat tubes. The connecting tube includes: two connection sections and a bent section, the two connection sections are disposed at two ends of the bent section respectively, the two connection sections are connected with the bent section to form a U-shaped tube, and an end, far away from the bent section, of the connection section is provided with a connection port; and the connection port has a flat mouth structure. According to a technical solution provided by the disclosure, a technical problem that a manufacturing process of a flat tube in the art known to inventors is complicated can be solved.

The invention relates to a connecting device having a female part and a complementary male part, wherein the female part is a sleeve able to receive at least partially the associated male part with a gap between the sleeve and the male part for receiving a brazing material. The sleeve at least partially has a conical shape. The conical shape has a first substantially conical part having a complementary shape to the male part, with a first inclination angle with respect to a longitudinal axis of the sleeve. The conical shape also has a second substantially conical part with a second inclination angle with respect to the axis, with the second inclination angle being larger than the first inclination angle.

A return bend ringing apparatus includes a ring station configured to receive a pair of rings and a pair of pins configured to move between a retracted position and an extended position. Each pin includes a tapered end and a shoulder. The pins in the retracted position are configured not to engage the rings, and the pins in the extended position are configured to engage the rings with each pin extending through one of the rings. A gripper is configured to grip and move a return bend into an engagement position in which the return bend engages the shoulder of each pin.

A face plumbing adapter having a block portion and a camber portion is provided for a manifold of a heat exchanger assembly. The block portion includes an external planar face, a first mating surface opposite that of the planar face, and an aperture having a B-axis extending through the planar face and first mating surface. The camber portion extends integrally from the block portion in a direction away from the planar face and curving inward toward the B-Axis. The camber portion is biased toward the block portion such that the face plumbing adapter would clinch onto the manifold. The block and camber portions include respective mating surfaces that are complementary to the exterior surface area of the manifold onto which the mating surfaces are affixed.
