Apparatus for adjusting the temperature of a plurality of liquids which includes temperature adjusting means having a corresponding plurality of separate flow paths, a pump arrangement for circulating the liquids through said separate paths and means for maintaining predetermined temperature differences between the liquids, wherein the temperature adjusting means includes a single temperature controlling member and a number of pipes which correspond in number to the number of separate flow paths for the liquids of which the temperatures are to be adjusted. The temperature controlling member and the pipes are interconnected in heat conducting so that the total thermal impedance between the first of said pipes and the temperature controlling member integrated from the inlet end to the outlet end of said first pipe differs from the corresponding total thermal impedance of at least a second of said pipes. The first of said pipes is located directly in heat conducting manner on the temperature controlling member and said at least second of said pipes is carried by said first of said pipes in a heat conducting manner. The thermal impedance defined between said at least second of the pipes and the temperature controlling member being thus formed by said first of the pipes.
Apparatus for adjusting the temperature of a plurality of liquids, comprising temperature adjusting means having a corresponding plurality of separate flow paths, a pump arrangement for circulating the liquids through said separate flow paths of said temperature adjusting means and comprising means for maintaining predetermined temperature differences between the liquids, characterized in that the temperature adjusting means includes a single temperature controlling member (12) and a number of pipes (14, 16) which correspond in number to the number of separate flow paths for the liquids of which the temperatures are to be adjusted, the temperature controlling member (12) and the pipes (14, 16) being interconnected in heat conducting manner such that the total thermal impedance between the first (14) of said pipes and the temperature controlling member (12) integrated from the inlet end to the outlet end of said first pipe differs from the corresponding total thermal impedance of at least a second (16) of said pipes, in that said first (14) of the pipes is located directly in heat conducting manner on the temperature controlling member (12) and said at least a second of said pipes is carried by said first (14) of said pipes in a heat conducting manner, the thermal impedance defined between said at least a second (16) of the pipes and the temperature controlling member (12) being thus formed by said first (14) of the pipes.
