Abstract

Ved i et pumpehus til en elektromagnetisk pumpe til fremdrivning af en ledende væske i et kølekredsløb, især til køling af elektriske komponenter, hvilket pum pehus omfatter en overpart og en underpart, der samlet udgør et pumpekammer med en indvendig overflade, og hvor underparten er udformet med åbninger til rør for kølekredsløbet, hvilke åbninger viser ind til pumpekammeret, og hvor pumpehuset yderligere er udformet med to åbninger til elektroder, hvilke åbnin ger viser ind til pumpekammeret og er anordnet på modstående sider af pumpe- huset og udstyret med elektroder, at indføre forbedringer, der består i, at pumpe kammerets (4) indvendige overflade (5) forsynes med en belægning (10) med elektrisk isolerende egenskaber, opnår man at reducere de elektriske spred ningstab i væsentlig grad. Ved yderligere at tilvejebringe elektroder med lav overgangsmodstand, og som kan sikre en god kontaktflade til den ledende køle væske, opnår man at reducere elektriske tab i elektroder og i pumpehusets gods.In a pump housing for an electromagnetic pump for propelling a conductive liquid in a cooling circuit, in particular for cooling electrical components, said pump housing comprising an upper part and a lower part, which together constitute a pump chamber with an inner surface, and wherein the lower part is formed with openings for pipes for the cooling circuit, which openings point into the pump chamber and wherein the pump housing is further designed with two openings for electrodes, which openings point into the pump chamber and are arranged on opposite sides of the pump housing and equipped with electrodes, to introduce improvements consisting in providing the inner surface (5) of the pump chamber (4) with a coating (10) with electrically insulating properties, a considerable reduction of the electrical scattering losses is achieved. By further providing electrodes with low transition resistance and which can ensure a good contact surface for the conductive coolant, electrical losses in electrodes and in the pump housing are achieved.
