Abstract

The invention discloses a novel graphite corrugated heat exchange plate heat exchanger which comprises a first cover plate, a first seal head, seal gaskets, graphite heat exchange plates, a second seal head, a second cover plate and a fastening piece. The first cover plate and the second cover plate are symmetrically arranged; the multiple layers of graphite heat exchange plates are arranged between the first cover plate and the second cover plate in a stacking way; the first seal head and the second seal head are arranged between the graphite heat exchange plates at two end parts and cover plates at end parts; and the graphite heat exchange plates are separated through the seal gaskets and are fixed through fastening pieces in a penetrating way. According to the graphite corrugated heat exchange plate heat exchanger provided by the invention, the thicknesses of heat exchange plate sheets are equal, the heat exchange efficiency of the heat exchanger is superior to the heat exchange efficiency of a diamond hole graphite heat exchange block and a common graphite heat exchange plate, and plate sheet patterns can be processed into different forms according to the requirements.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a novel graphite corrugated heat exchange plate heat exchanger. Background technique [0002] The cross-section of the heat exchange plate in the existing graphite heat exchanger (such as image 3 As shown), generally adopt the form of milling grooves (material circulation channels) on graphite plates. The wall thicknesses of the top and bottom of the material circulation channels of the heat exchange plate are different, among which the wall thickness of the bottom of the groove is the thinnest, and the wall thickness of the top of the groove is the thinnest. Maximum wall thickness. It can be seen that the thermal resistance of the place with different thickness on the heat exchange plate is also different. Where the wall thickness is thin, the thermal resistance is small and the heat transfer efficiency is high, and where the wall thickness is large, the thermal resistance is large and the ...
