Temperature Control Unit for a Gaseous or Liquid Medium

Abstract

For a temperature control unit for gaseous or liquid medium with a highly dynamic temperature regulation of the medium, the temperature control unit ( 1 ) is designed with a base body ( 2 ) and a cooling body ( 5 ) between which are arranged multiple thermoelectric modules ( 7 ) and with a media line ( 6 ) in the base body ( 2 ), and it is provided that the mass ratio of the thermal storage mass of the cooling body ( 5 ) to the thermal storage mass of the base body ( 2 ) and the media line ( 6 ) arranged therein is in the range of 0.5 to 1, advantageously in the range of 0.7 to 0.8.

1 . A temperature control unit for temperature control of a gaseous or liquid medium by means of a number of thermoelectric modules, which are arranged between a base body and a cooling body, and a media line through which the gaseous or liquid medium flows is arranged in the base body, wherein the mass ratio of the thermal storage mass of the cooling body to the thermal storage mass of the base body and the media line arranged therein is in the range of 0.5 to 1, advantageously in the range of 0.7 to 0.8. 
     
     
         2 . The temperature control unit according to  claim 1 , wherein the mass ratio is 0.75. 
     
     
         3 . The temperature control unit according to  claim 1 , wherein a groove into which the media line is pressed is provided in the base body. 
     
     
         4 . The temperature control unit according to  claim 3 , wherein the media line is arranged in the base body in the form of a spiral leading from the outside to the inside. 
     
     
         5 . The temperature control unit according to  claim 3 , wherein the media line is arranged in the base body in the form of a two-start spiral in a first spiral start leading from the outside to the inside and in a second spiral start connected radially at the inside to the first spiral start leading from the inside to the outside. 
     
     
         6 . The temperature control unit according to  claim 5 , wherein the multiple thermoelectric modules are arranged in a plurality of rows on the base body wherein the module heating power of a thermoelectric module situated further toward the outside radially is greater than the module heating power of a thermoelectric module situated further toward the inside radially. 
     
     
         7 . The temperature control unit according to  claim 1 , wherein the base body is surrounded by a base body jacket wherein a plurality of radial connecting webs which are connected to the base body jacket are arranged over the circumference of the base body. 
     
     
         8 . The temperature control unit according to  claim 7 , wherein the base body jacket is designed to be partially hollow. 
     
     
         9 . The temperature control unit according to  claim 1 , wherein a cooling line through which cooling medium for cooling the cooling body flows as needed is arranged in the cooling body. 
     
     
         10 . The temperature control unit according to  claim 9 , wherein the cooling line is arranged in the form of a spiral. 
     
     
         11 . The temperature control unit according to  claim 1 , wherein the media line is arranged in the base body in the form of a spiral leading from the outside to the inside. 
     
     
         12 . The temperature control unit according to  claim 1 , wherein the media line is arranged in the base body in the form of a two-start spiral in a first spiral start leading from the outside to the inside and in a second spiral start connected radially at the inside to the first spiral start leading from the inside to the outside. 
     
     
         13 . The temperature control unit according to  claim 4 , wherein the multiple thermoelectric modules are arranged in a plurality of rows on the base body wherein the module heating power of a thermoelectric module situated further toward the outside radially is greater than the module heating power of a thermoelectric module situated further toward the inside radially.
