Cooling compress for cooling a detector

Abstract

To cool detectors of level measuring devices, it is possible to use cooling compresses which are fastened to the detector housing. Such a cooling compress includes a cooling body which at least in part consists of a deformable material. The inner wall of the cooling body of the cooling compress is configured such that it moves towards a corresponding region of the outer surface of the detector to form a thermal contact with a corresponding region of the outer surface of the housing when a cooling fluid flows through the cooling body.

1 . A cooling compress for cooling a detector of a level measuring device during a level measurement, comprising:
 a cooling body at least in part consisting of a deformable material, the cooling body being configured for attachment to the detector, the cooling body being configured for a through-flow of a cooling fluid,   wherein at least one region of an inner wall of the cooling body is configured to move towards a corresponding region of an outer surface of the detector to form a thermal contact with the corresponding region of an outer surface when the cooling compress is attached to the detector and when the cooling fluid flows through the cooling body.   
     
     
         2 . The cooling compress according to  claim 1 , wherein the cooling compress is configured as a sleeve for being placed over the detector. 
     
     
         3 . The cooling compress according to  claim 1 , further comprising:
 a first layer forming an outer wall of the cooling body;   a second layer forming an inner wall of the cooling body;   an introduction opening; and   a discharge opening;   wherein the first layer and the second layer are joined together such that they form a cavity in the cooling body to receive the cooling fluid;   wherein an access to this cavity is provided via one of (a) the introduction opening and (b) the discharge opening;   wherein during an operation of the cooling compress, the cooling fluid is under a pressure which is greater than the pressure of the medium surrounding the cooling body;   wherein the second layer consists of a deformable and thermoconducting material; and   wherein the volume of the compress increasES as a result of introducing the cooling fluid into the cooling body.   
     
     
         4 . The cooling compress according to  claim 3 , further comprising:
 a fastening device holding the cooling compress on the detector.   
     
     
         5 . The cooling compress according to  claim 3 , wherein a layer of textile fabric, Kevlar or similar material is arranged on the outside of the first layer. 
     
     
         6 . The cooling compress according to  claim 3 , wherein at least one of (a) the introduction opening and (b) the discharge opening is configured as a bushing. 
     
     
         7 . The cooling compress according to  claim 1 , further comprising:
 an electrically operated heating element heating the cooling fluid.   
     
     
         8 . The cooling compress according to  claim 1 ; wherein the cooling compress has recesses which are configured such that elements of the housing surface of the detector are accessible from outside when the cooling compress is attached to the detector. 
     
     
         9 . A level measuring device, comprising:
 a cooling compress according to  claim 1 .   
     
     
         10 . The level measuring device according to  claim 9 , wherein the inner wall of the cooling body rests in a close-contoured manner against the housing surface, to be temperature controlled, of the detector. 
     
     
         11 . The level measuring device according to  claim 9 , wherein the cooling compress has a recess which is configured such that elements of the housing surface of the detector are guided through the recess and are thus accessible from outside. 
     
     
         12 . Use of a cooling compress according to  claim 1  for cooling a housing of a measuring device. 
     
     
         13 . Use according to  claim 12 , wherein the housing is a housing of a detector of a level measuring device. 
     
     
         14 . A method for controlling a temperature of a detector using a cooling compress, comprising the steps:
 passing cooling fluid through the cooling compress, wherein the pressure of the cooling fluid inside the cooling body is greater than the pressure of the medium surrounding the cooling body, as a result of which at least one region of an inner wall of the cooling body moves towards a corresponding region of an outer surface of the detector to form a thermal contact with the corresponding region of the outer surface of the detector, when the cooling fluid flows through the cooling body.
