Abstract
A transducer for mechanical measured variables, especially a pressure transducer, having a heat pipe system within the housing, the heat pipe system is connected on one side to the thermally high stressed parts of the transducer, and on the other side to parts not exposed to heat or cold. The sensor element of the transducer is cooled through heat transport by means of an alternatively vaporizing and condensating working fluid within the heat pipe system.
Claims13
A transducer for measuring mechanical varibles having a housing and a heat pipe system arranged therein, said heat pipe system being heat-conductingly connected on one part thereof to the thermally stressed parts of the transducer, said heat pipe system comprising at least one self-contained closed receptacle, having walls at least partially lined with wick material to form a hollow space in said receptacle, a working fluid for wetting said wick material and being distributed by capillary action of the wick material, the working fluid circulating through the capillaries of the wick and the vapor of the working fluid circulating through said hollow space forming a closed loop, whereby heat transfer occurs by the convection of latent heat in the vapor phase of the fluid to improve the temperature balance within said hollow space.
