A heat exchanger arrangement is provided with a housing provided with a fluid inlet and a fluid outlet and designed to be flowed through by the fluid. A heat exchanger is arranged in the housing between fluid inlet and fluid outlet and surrounded by the housing. The heat exchanger is arranged such that the fluid can flow through the heat exchanger. The housing has a seal contour. The heat exchanger is connected with form fit at a fluid inlet of the heat exchanger or at a fluid outlet of the heat exchanger to the seal contour of the housing. In a method of producing the heat exchanger arrangement, a seal surface of the seal contour of the housing is melted and pressed against a seal region of the heat exchanger at the fluid inlet of the heat exchanger or at the fluid outlet of the heat exchanger.

A solar heat exchanger in which the manifolds are connected together using a threadless connection arrangement in which the end of one manifold tube carries at least two annular seals and the internal bore of the end of the adjacent manifold tube is cammed and when locked, the connection of the two manifolds is resistant to loosening when exposed to repeated thermal expansion and contraction cycles.

A system and method for thermally exchanging heat between waste air being expelled from a poultry barn and fresh outside/outdoor ambient air being introduced into the poultry barn.

A heat exchanger may include a first component composed of a first material and a second component composed of a second material. The first component and the second component may each have an edge zone. The first component and the second component may abut against one another in an overlapping manner at the edge zone and may be joined together. At least the edge zone of the first component may consist of a material impermeable to laser beams. The edge zone of the first component may externally overlap the edge zone of the second component and abut against the edge zone of the second component in direct contact and may be joined thereto via a fusion bond.

In the production of carbon black by the furnace process, fuel and heated combustion air or oxygen enriched air from the combustion air heat exchanger, are fired into the reactor, resulting in a hot flame. Carbonaceous feed stock, injected into this hot flame containing considerable excess oxygen, is pyrolized. The effluent from the reactor reaction zone is quickly cooled, typically by water quench, to prevent secondary reactions that decrease the quality and yield of carbon black. In the present invention, water quench is eliminated and the effluent from the reaction zone passes directly into the metallic combustion airheater, quickly cooling it to stop pyrolysis and heating the combustion air to typically 950 C. The combustion air heater is smaller due to high heat flux per unit volume. Further cooling of the effluent to the carbon black collector, is achieved by series of heat exchangers and trimming water quench.
