The present disclosure provides a holder for holding a tube connector for an in-vehicle component. The holder includes a first arm that has a first engaging portion, a second arm that has a second engaging portion, and a fastener. A proximal portion of the first arm is connected to a proximal portion of the second arm at a connection point. The first arm and the second arm are configured to be flexible toward each other by flexing about the connection point. The first engaging portion and the second engaging portion engage with the tube connector by clamping the tube connector therebetween. The fastener fixes the proximal portion of the first arm and the proximal portion of the second arm to a base while biasing the first arm and the second arm toward each other.

Provided are a heat exchanger equipped with a cold reserving part and a manufacturing method thereof, equipped with a cold reserving part, in which since a cold reserving material charging part is formed at a portion at which an inlet and outlet member is formed, an additionally protruding part to inject the cold reserving material is not required, such that the heat exchanger may be miniaturized and may more rapidly and effectively absorb cold air to increase a cold reserving effect, and a manufacturing method of a heat exchanger equipped with a cold reserving part which forms the cold reserving material charging part to charge the cold reserving material after coating the heat exchanger to block a coating solution from introducing into the heat exchanger, thereby preventing the heat exchanger from corroding due to the coating solution to increase durability and more increase manufacturing performance.

A radiator includes a main body, two connecting members and two taps. The two connecting members are disposed on opposite sides of the main body. Each of the two taps is rotatably connected to one of the two connecting members, such that the two taps are rotatably disposed on opposite sides of the main body.

The invention relates to an indirect-type air cooler by way of which compressed charge air for an internal-combustion engine is cooled by means of a liquid, wherein the air cooler is constructed from stacked pairs of plates having fins which are disposed therebetween, and the brazed stack is disposed in a housing into which the charge air flows, flows through the fins and exits the housing again. The charge air exchanges heat with the liquid which flows in the plate pairs and which is introducible into the plate pairs via at least one inlet and via inlet-side plate openings which are flush in the stack and is dischargeable via at least one outlet by means of flush outlet-side plate openings. In order to further improve the performance potential of the air cooler, at least one venting element which extends to the exterior through an opening of the housing is connected to a liquid space within the stack.

The invention relates to a connection interface (20) for a connection assembly (10) for connecting refrigerant tubes in a cooling assembly of a motor vehicle electrical storage device, the connection assembly (10) comprising at least one flange (18) made integral with a heat exchange member (4), said connection interface (20) being arranged at end portions (24) of refrigerant fluid tubes to be connected to said heat exchange member, characterised in that the connection interface (20) comprises a first portion (50) integral with the end of each of the tubes (12) and a second portion (52) mounted freely around the tubes, the second portion comprising openings (64, 66) for passing the tubes dimensioned to allow a clearance for relative movement therebetween of the two portions (50, 52) of the connection interface (20), at least in a plane perpendicular to a direction of elongation of the end portions of the tubes, the connection interface (20) being configured to engage with a securing member (36) capable of setting the position of the two portions relative to each other.
