Crossing-flow heat exchanger

专利摘要:
Invention m. used when operating in conditions of high m-p and aggressive media. The purpose of the invention is to increase the operational reliability of the heat exchanger. The metal housing 1 has two nozzles of the inlet 2.3 and outlet 4.5 gas and krpiku 6 from the top side. The case contains a block of ceramic heat exchange elements (E) 7, having the shape of parallelepipeds with mutually perpendicular channels 8.9. Channels

the sides are provided with thermal insulation 16, covering the unit. Tape 12 may be made of ceramic material. In front of the block of heat exchange elements 7, one supporting support 17 can be located on the side surfaces.
In the manufacturing process, heat exchange elements 7 are completed layer by layer, with gaps contained at the butt edges of the gaps, and mounted on the base of the housing 1. After the unit is completely assembled, a key 6 is installed on the housing 1 with a corresponding seal. Due to the presence between the lateral surfaces of the elements 7 of the hollow chambers 15, an exact alignment of the through channels 8 and 9 on the lateral surfaces of the element 7 is optional.
The proposed heat exchanger can operate under high temperature conditions and with an appropriate choice of ceramic material it can be resistant to corrosion environments.
