A heat exchanging arrangement for a subsea electronic system, the heat exchanging arrangement including a wall section; a corrugation formed in the wall section, the corrugation having two generally opposing internal corrugation surfaces; and at least one heat exchanging element forced against at least one of the internal corrugation surfaces. A subsea electronic system including a heat exchanging arrangement is also provided.

An arrangement has a housing, which has a receptacle or an opening, and a cylindrical insert, which is mounted in the receptacle or opening via at least one interference fit. The insert has a peripheral groove, and therefore the insert is both fastened against the housing and sealed against the housing in a liquid- and/or gas-tight manner by way of material of the insert and/or housing that has been pressed into the groove during the assembly. The material of the insert and/or of the housing is displaced in the case of an interference fit. The groove provides a defined location to which the material can preferably flow. After the assembly has been concluded, the insert is locked against the housing by the material located in the groove. At the same time, the material acts as a seal between the insert and the housing. A separate seal in the region of the press fit becomes dispensable.

A heat dissipation unit and a heat dissipation device using same are disclosed. The heat dissipation device includes a base and one or more heat dissipation units. The base has a first side and an opposite second side; and the heat dissipation units respectively include at least one radiation fin correspondingly provided on the first side of the base. The radiation fin is formed by correspondingly closing a first plate member and a second plate member to each other, such that a plurality of independent flow channels is defined between the closed first and second plate member. And, the independent flow channels respectively have an amount of working fluid filled therein.

A heat exchanger includes a metal tube and a composite polymer fin in thermal contact with the metal tube. The fin is formed of a polymer and a thermally conductive filler such that the fin has a thermal conductivity greater than or equal to 0.5 Watts per meter Kelvin.

A recuperator including a number of neighbouring hexagonal sheets which are connected to each other. Flow passages are formed between neighbouring sheets. Each of the sheets, at its periphery, is at least partially surrounded by and connected to an associated connecting body. Neighbouring connecting bodies are connected to each other at at least a part of the periphery of the associated sheets and together form the wall of a housing. Passage openings are provided in the wall which are connected to the flow passages for allowing air into the flow passages via the passage openings. Neighbouring connecting bodies are provided with protruding parts and with recesses respectively on sides facing each other, wherein the forms of the protruding parts and of the recesses adjoin each other in order to connect the connecting bodies to each other by a press fit. Methods for producing a connecting body and for producing a recuperator.

In one embodiment, an apparatus includes a module for use in installing a heatsink, the module comprising a fastener, a first indicator member comprising a first visual indicator surface, and a second indicator member comprising a second visual indicator surface, the first and second indicator members defining an opening for receiving the fastener. The first visual indicator surface is visible when the fastener is not fully installed and the second visual indicator surface is visible when the fastener is fully installed. A method for installing the heatsink with the module is also disclosed herein.

A cooling arrangement for a battery box includes a plate-shaped heat exchanging element, a cooling channel secured to the heat exchanging element, and a fluid collector for collecting or feeding a fluid into the cooling channel. The fluid collector includes a volume region and has a receiving opening on a side proximate to the cooling channel for introduction of the cooling channel to thereby fluidly connect the volume region with the cooling channel. A sealing element and a clamping element are arranged on an outside of the fluid collector at the receiving opening, with the clamping element being traversed by the cooling channel. A clamping tab is arranged above or below the receiving opening in surrounding relationship to the sealing element and the clamping element to thereby secure the cooling channel immovably to the fluid collector.

An object of the present invention is to provide a heat exchanger that is structurally coupled to an endplate without a process of welding a connection member. To achieve the above-mentioned object, a heat exchanger according to the present invention may include a plurality of main plates each including a through-hole through which a heat exchange medium flows, and an outer wall formed at a periphery thereof, the plurality of main plates being stacked to constitute a heat exchanger core having a flow path formed therein, an endplate being in surface contact with the main plate disposed at an outermost side of the heat exchanger core, the endplate having one or more connection holes, and a connection member configured to be connected to an external component and at least partially inserted into the connection hole.

A lighting system includes two or more lighting fixtures, each comprising a housing, at least one light source mechanically supported by the housing, at least one pipe thermally coupled to the housing to carry a fluid coolant, an AC power port, and at least one network communications port. The AC power ports of respective lighting fixtures are coupled together with a plurality of industrial power cables without using one or more conduits for the plurality of industrial power cables. The network communications ports of the respective lighting fixtures are coupled together with a plurality of waterproof network communications cables. In one example, a lighting system kit comprises two or more lighting fixtures having an AC power port comprising an industrial type connector. The kit further comprises multiple industrial power cables and one or more industrial drop tee cables.

The disclosed apparatus may include (1) a base that (A) supports multiple heatsinks and (B) is coupled to a device that includes (i) a first component designed to operate at temperatures below a first threshold temperature and (ii) a second component designed to operate at temperatures below a second threshold temperature, the first threshold temperature being different than the second threshold temperature, (2) a first heatsink that (A) is secured to the base and (B) transfers heat away from the first component such that the first component operates at a temperature below the first threshold temperature, and (3) a second heatsink that is (A) secured to the base, (B) physically separated from the first heatsink by at least a certain amount of space, and (C) transfers heat away from the second component such that the second component operates at a temperature below the second threshold temperature.
