An adapter element may have a first end section and a second end section. The adapter element may be connected to a rim of the cooler box that borders the cooler box passage opening. A pipe element may be detachably secured to the adapter element and have a first end section and a second end section. The first end section of the adapter element and the first end section of the pipe element may define a clip-type connection when the adapter element and the pipe element are secured to one another.

A cooling module including: a radiator including: first and second header tanks disposed to face each other; and hook parts respectively disposed at upper and lower sides of the first header tank and a lower side of the second header tank; and a condenser including: third and fourth header tanks disposed to face each other; a flange connection part coupled to the third header tank; and a gas-liquid separator coupled to the fourth header tank, in which the condenser is coupled to the radiator as the flange connection part, the third header tank, and the gas-liquid separator are inserted into the plurality of the hook parts, respectively, in a direction from an upper side to a lower side thereof.

A fixing device includes a gasket and a clip. The clip includes a clip upper portion, a clip body portion, and a clip leg portion. The clip upper portion has a width wider than the clip body portion and the clip leg portion. The clip upper portion, the clip body portion, and the clip leg portion are connected to form an open loop facing downward. The gasket includes a gasket upper portion, a gasket intermediate portion, and a gasket base portion forming an A shape. The gasket is compressible. The clip upper portion and the clip body portion define two receiving areas evenly distributed at two inner sides of the clip. The gasket is evenly and simultaneously compressed toward the two receiving areas of the clip while the clip moves downward without tilting or slanting.

A heat exchanger unit, especially for a vehicle heater, includes a heat exchanger housing (12) with a heat transfer medium inlet opening (22) and with a heat transfer medium outlet opening (24). At least one connecting branch (26, 28), is inserted or can be inserted into the heat transfer medium inlet opening (22) and the heat transfer medium outlet opening (24). At least one housing locking element meshing recess (34, 36, 38, 40) is provided in association with the at least one connecting branch (26, 28) in the heat exchanger housing (12). A locking element (44), locking the connecting branch (26, 28) on the heat exchanger housing (12), is positioned or can be positioned such that the locking element (44) meshes with the at least one housing locking element meshing recess (34, 36, 38, 40) and with at least one connecting branch locking element meshing recess (42).

A connector suitable to be connected to a multi port extruded tube comprises a socket suitable for an end section of a multi port extruded tube to inserted into the socket along a linear insertion direction, whereby the socket contains an end section receiving space suitable to receive the end section of a multi port extruded tube, the end section receiving space bordering a first opening suitable for a multi port extruded tube to extend through it, whereby a cap arranged inside the socket such that the cap can slide from a forward position that is closer to the first opening to a backward position that is further away from the first opening, the cap having an outer circumferential surface whereby a sealing is provided inside the socket that contacts the outer circumferential surface of the cap in the forward position of the cap.

The present invention provides a heat exchanger, comprising a plurality of first heat exchange plates (1) and second heat exchange plates (2) that are connected sequentially and at an interval; the first heat exchange plates (1) and the second heat exchange plates (2) each comprise a heat exchange sheet (3) and a heat exchange frame (4) disposed on side ends of the heat exchange sheet (3); the side ends of the heat exchange sheet (3) are formed with a snap projection (9) in a direction away from the heat exchange frame (4); the heat exchange frame (4) is formed with a snap groove (10); the first heat exchange plates (1) and the second heat exchange plates (2) are in interference connection through the engagement between the snap projection (9) and the snap groove (10); an air channel (5, 6) is formed between a first heat exchange plate (1) and an adjacent second heat exchange plate (2), the air inlet of the first heat exchange plate (1) and the air inlet of the second heat exchange plate (2) have different directions, and the air outlet of the first heat exchange plate (1) and the air outlet of the second heat exchange plate (2) have different directions. The present invention puts the first heat exchange plate (1) and the second heat exchange plate (2) in interference connection through the engagement between the snap projection (9) and the snap groove (10), which effectively ensures stability and reliability of the connection, and ensures the airtightness of the connection.

The present disclosure relates to an assembly forming a heat exchanger or part of a heat exchanger. The assembly comprises a core with at least one insert in the form of a side plate, and a header plate attached to the or each insert by at least one snap fit connection. Accordingly, the assembling process of the assembly can be facilitated, and cost of the assembly can be reduced.

A heating element cover component includes a hollow outer shell portion of a required length, having required rigidity and thermal conductivity, a substantially half-pipe shaped abutting portion formed with a required thickness on the outside of the outer shell portion in a longitudinal direction of the outer shell portion, having flexibility and thermal conductivity, and with a slit penetrating in a thickness direction formed over the entire length in the longitudinal direction, a connecting portion having flexibility and thermal conductivity, connecting opposed edges of the abutting portion in the longitudinal direction with the outer shell portion, and an engaging portion constituted with a projecting piece and a projecting piece inserting portion being engaging elements disposed at line-symmetrical positions using a longitudinal straight line located at a widthwise middle of the abutting portion as an axis of symmetry to form a pair structured to be engageable with each other.
