Abstract
A heat baffle plate of aluminum or another good heat-conducting metal is secured on a steel member. Since aluminum cannot be welded to steel, connections are utilized which result in a good heat-conducting connection but without direct welding. For example, a steel plate can be placed over a portion of the heat baffle plate and then be welded through openings in the aluminum plate to the steel member. The baffle plate can alternatively be supported by a form-locking engagement with a holding plate of steel which is welded to the steel member. The better heat conductivity of the aluminum baffle plate causes the heat emission or heat absorption to be substantially increased for a given structural arrangement in comparison to a heat baffle plate of steel.
Claims25
A heat exchanger, comprising a steel member and at least one heat baffle plate which is connected heat-conductingly to and projects outwardly from said steel member, wherein said heat baffle plate is made of a metal having a heat conductivity greater than the heat conductivity of steel, wherein said heat baffle plate is held against said steel member by a further member which is welded to said steel member, and wherein said further member is a steel plate which rests against said heat baffle plate and in plural locations has portions which project through openings in said heat baffle plate, each said portion being welded to said steel member.
A heat exchanger, comprising a hollow steel member which has a cavity through which a liquid heat carrier medium can flow and a heat baffle plate which is dipsosed heat-conductingly against said steel member and projects outwardly therefrom, wherein said heat baffle plate is made of a metal having a heat conductivity which is greater than the heat conductivity of steel, and wherein said heat baffle plate is held against said steel member by a further member which is welded to said steel member.
