US 4,733,720 A · Water cooling means for insertable component parts groups in devices of power electronics

Abstract

In a water cooling arrangement for insertable component parts groups in devices of power electronics, the carrier element on which the component parts are arranged is fashioned as a component parts carrier independent of the cooling member. A water-traversed cooling member which is seated essentially apparatus-rigid can be individually brought into thermal interaction with every component parts carrier inserted into the device in the composite of an insert being brought into thermal interaction therewith by the force of resilient elements at heat transmission surfaces precisely mating to one another which are fashioned at component parts carriers and cooling members. With a mechanical device all cooling members can be distanced in common from the apertaining component parts carriers opposite the acting direction of the forces of the resilient elements. A replacement of component parts carriers is thereby enabled without performing manipulations at devices of the cooling water circulation.

Dependent claims

In a water cooling means for insertable component parts groups in devices of heat generating power electronics wherein water is used as a coolant to remove excess generated heat, the water being separated from the electronics parts by a metallic carrier element, the improvement comprising:

fashioning a carrier element independently from a cooling member;
said cooling member being water permeated and being mounted on resilient elements to be urged into thermal transfer contact with said carrier element;
said cooling member and said carrier element having heat transmission surfaces precisely matable with one another;
and
said cooling member being displaceable by a device acting thereon opposite to a force of said resilient elements, thereby permitting said cooling member to be selectively spaced from said carrier element.

2 more elements

A water cooling means for insertable component parts groups in devices of power electronics based on the principle wherein the stray heat essentially flows from the component parts directly into the cooling water via a layer of metal having good thermal conductivity fashioned as a carrier element which is necessary for separating the component parts from the cooling water flowing through the cooling members, comprising the improvement wherein the carrier element on which the component parts are arranged is fashioned as a component parts carrier independent of the cooling member;

in that a respective, water-permeated cooling member seated on resilient elements essentially apparatus-rigid can be individually brought into immediate, pressurized-planar thermal interaction with every component parts carrier inserted individually or in plurality into the apparatus in the composite of an insert, being brought into this thermal interaction therewith in the operational final position thereof at heat transmission surfaces precisely mating with one another which are fashioned at component parts carriers and cooling members;
and in that all cooling members are displaceable in common by a device acting on them in identical fashion opposite the acting direction of the forces of the resilient elements and being thus spaceable from the apertaining component parts carriers.
