Problems solved by technology
The disadvantage of this patent is that the heat exchanger uses water as the heat exchange medium. In order to keep the temperature of the heat exchanger itself not higher than the boiling point of water, water must always be passed through the heat exchanger during the heating and cooling process of the equipment, causing the equipment During the heating process, part of the heat will be taken away by the heat exchanger

Description
technical field [0001] The invention relates to equipment in the technical field of heat treatment, in particular to a heat treatment furnace that adopts heat pipes for rapid cooling. Background technique [0002] The function of the heat treatment furnace is to heat and keep warm the processed workpiece in the atmosphere, protective atmosphere or vacuum, and then take the processed workpiece out of the heat treatment furnace for cooling or cool it in the heat treatment furnace according to the set cooling process. In order to achieve the purpose of cooling in the heat treatment furnace according to the set cooling process, many cooling methods are adopted. Among them, setting a heat exchanger in the heat treatment furnace is a relatively common method. One of the ways to install a heat exchanger in the heat treatment furnace is to set a heat exchanger with water as the cooling medium at a certain position of the heat treatment furnace body. When the heat treatment furnace ...
