Title:
CONSTANT TEMPERATURE BATH FOR LIQUID CHROMATOGRAPH
Document Type and Number:
Japanese Patent JPH01219665
Kind Code:
A
Abstract:

PURPOSE: To enable the implementation of a temperature control for cooling and heating with excellent responsiveness, by using a thermomodule.

CONSTITUTION: A cooling or heating operation of a thermomodule 8 is propagated into a constant temperature bath 1 through a heat-conductive material 7, convection is made by a fan 12, and the inside of the bath 1 is cooled or heated. The operation heat of the module 8 is released through a heat-releasing fin 9. On the occasion, the heat is released along an outer wall by a partition plate 14. Meanwhile, the air blown against the module 8 or a communication hole 6 by an external fan 13 is guided by the partition plate 14 so that it goes straight on, and does not mix with the heat released from the fin 9. Therefore, the heating or cooling operation of the module 8 is propagated from the communication hole 6 and through the heat-conductive material 7 and implemented in the bath 1 in an efficient manner.
