A heat exchanger system includes a housing defining an interior volume, one or more tubes extending within the interior volume of the housing, and a turbulator disposed within one or more of the tubes. The turbulator induces turbulence in a fluid flow through the tube, and includes a cylindrical body having a first, outer surface and a second, inner surface opposite to the first, outer surface, and multiple protrusions coupled to the cylindrical body and extending at least partially inwardly from the inner surface of the body.

A cover (25) is intended to be attached to a housing (2) of a heat exchanger (1). The cover (25) comprises a wall (26) that is intended to close off an orifice (5) for introducing a heat exchange core into the housing (2). The wall (26) is configured to allow the cover (25) to be attached removably to the housing (2) and has a raised edge (27). The cover (25) also comprises means (30) for mechanical reinforcement of the wall (26). The invention also relates to a heat exchange core (7) comprising the cover (25), to a heat exchanger (1) comprising the core (7), and to an air intake module for a motor vehicle combustion engine comprising the heat exchanger (1).

When products to be shipped are temperature-sensitive, it is necessary to maintain a substantially uniform and constant temperature to avoid spoilage. As a result, thermal shields are often placed on top of the products. Many designs for thermal shields have been considered in the past but improvements are still desired. Accordingly, there is provided a multilayer thermal shield (100) comprising a thermally conductive layer (108), and at least one heat exchange fluid circuit (120) coupled to a first surface of the thermally conductive layer, the at least one heat exchange fluid circuit comprising at least one inlet (124) configured to permit the ingress of heat exchange fluid. The thermal shield further comprises an outer insulation layer (104) connected to a first surface of the thermally conductive layer (108) and comprising grooves designed to receive the heat exchange fluid circuit. The thermal shield further comprises an inner insulation layer (110) connected to a second surface of the thermally conductive layer (108).

It is intended to suppress occurrence of a crack in a fixed portion of a tube with respect to a tank. A plurality of tubes (4A to 4D) are fixed to a sidewall (9) in a state in which they penetrate through the sidewall (9) via respective ones of a plurality of through-holes (9b) formed in the sidewall (9) in such a manner as to be arrayed in a line along a longitudinal direction. A heat exchanger (1) comprises a protective member (5) fixed to the sidewall (9) to protect a nearest tube (4A) nearest to an end wall (10) among the plurality of tubes (4A to 4D), wherein the protective member (5) has a barrier portion (13) interposed between the end wall (10) and an outlet-side end portion (4b) of the nearest tube (4A) disposed inside the sidewall (9).

In cooling/heating cycles of a heat exchanger, to prevent cracks that tend to occur in a brazed portion between an end portion of a horizontal cross-section of a tube and a header plate. An end portion cover body is provided for an end portion of a tank main body or a header to cover hereby an end portion in a longer side direction of an opening end portion of a flat tube.

The present invention relates to an exhaust-gas heat exchanger for a motor vehicle, having an encircling heat exchanger duct with a bypass pipe situated at the inside, a control flap being provided for conducting an exhaust-gas flow through the heat exchanger duct or through the bypass pipe, said exhaust-gas heat exchanger being characterized in that the control flap has an opening with a pipe stub-like section, the pipe stub-like section being in flow-conducting contact with an inlet opening of the bypass pipe in a bypass position, and the control flap being rotatable from a bypass position into a transfer position, in which the inlet is closed.

The present invention relates to a heat exchanger (20) comprising a protective device (1), mutually parallel tubes (22) through which a first fluid circulates, and perpendicular fins (26) connecting two successive flat tubes (22), a second fluid circulating between said flat tubes (22) by passing through said fins (26), said protective device (1) being apertured so as to allow the circulation of the second fluid through the fins (26), said protective device (1) comprising fixing spikes (7) which are inserted forcibly between the fins (26).

A heat exchanger is provided that includes a housing and an exchanger region which is arranged in the housing and has tubes and at least one base, wherein the tubes are connected to the at least one base, wherein the housing is manufactured from a plastic and has a housing inner surface, wherein the housing inner surface is covered at least in regions or in sections by at least one metallic element for protecting the housing from a thermal load. The invention further relates to a method for producing a heat exchanger.

An apparatus (1) for adjusting the heat exchange, comprising shielding means (10) intended to be arranged facing at least one portion of a heat exchanger (2), and provided with at least one screen (11) movable between a position of maximum covering (C) of the heat exchanger (2) and an exposure position, in which the heat exchanger (2) is left at least partially uncovered by the screen (11).

The liquid cooling system has a heat exchanger having a fluid inlet and an outlet; a fluid supply conduit leading to the inlet of the heat exchanger; a fluid return conduit extending from the outlet of the heat exchanger; a bypass conduit extending between the fluid supply conduit and the fluid return conduit; a thermal valve configured for selectively closing the bypass conduit, the valve having a temperature sensing element positioned downstream of both the heat exchanger and the bypass conduit, the temperature sensing element configured to selectively move the thermal valve in response to a temperature change of the liquid which the temperature sensing element is exposed to relative to a temperature threshold of the valve; and a deflector positioned between the temperature sensing element and at least one of the bypass conduit and the heat exchanger outlet.
