Temperature control device and method using peltier element

Abstract

A temperature control device and temperature control method both using a Peltier element. Heat insulation of the Peltier element and its connection elements is achieved without installing a vacuum vessel containing the Peltier element and its connection elements and its associated apparatus. Further, the system cost or apparatus cost can be reduced by simplifying the structure of the system or apparatus, and the accuracy of the control of the temperature at the contact surface according to the temperature determined by a temperature sensor can be improved. By using the temperature control device having a Peltier element, an object the temperature of which is to be controlled is rapidly cooled or heated through the contact surface of a conductor in contact with the object by the Peltier effect produced when a DC voltage is applied between the Peltier element and an electrode-cum-heat sink. The temperature control device is characterized in that an end cover is provided to cover the conductor, the Peltier element, and the whole or a part of the contact surface of the electrode-cum-heat sink, a gas layer having a closed space defined inside the cover and filled with gas is provide, and a heat insulating layer composed of a heat insulator is provided between the conductor and the gas layer in the closed space.

Description

technical field [0001] The present invention relates to an apparatus and method for controlling temperature by means of Peltier elements using Peltier elements capable of cooling and rapid cooling or heating of small localized areas with large temperature differences and large heat fluxes, more particularly Specifically, it relates to a device and method for temperature control by Peltier elements suitable for localized cryogenic treatment of cutaneous injuries such as skin or mucous membrane lesions. Background technique [0002] Although an electronic refrigeration system using a Peltier element is applied to localized cooling or freezing of optical instruments or electronic parts because the cooling temperature can be controlled according to the supplied electric power, it is difficult to realize due to its low cooling performance in a steady state Large temperature difference and large heat flow. [0003] Modules with multi-level Peltier elements have been developed. I...

AI Technical Summary

Problems solved by technology

The sensor is forced to be placed at the end or inner surface of the electrode heat sink on the side of the Peltier element, so the temperature of the contact surface of the temperature control surface cannot be accurately detected, which leads to a decrease in temperature control accuracy
