Abstract
A temperature control apparatus where it is easy to replace a heat exchange unit to enhance the maintainability and the space efficiency and which can absorb the thermal expansion/shrinkage of a heat exchanger is provided. The temperature control apparatus has a heat exchangerwith a passagefor passing a fluid; a connecting pipeconnected to the passage of the heat exchanger; a passage blockwith a passage for passing the fluid to the heat exchanger; a relay blockfor forming a passage between the passage of the passage block and the connecting pipe; and sealing meansfor connecting the connecting pipe movably to the passage of the relay block. In the temperature control apparatus, the length of the connecting pipeis made substantially equal to or slightly shorter than the spacing between the heat exchangerand the passage block
