Block-hole-type graphite heat exchanger with forcedly deflecting and sealing characteristic

Abstract

The invention discloses a block-hole-type graphite heat exchanger with a forcedly deflecting and sealing characteristic. The block-hole-type graphite heat exchanger comprises a heat exchanger cylinder body and a heat exchanging assembly arranged in the heat exchanger cylinder body. The heat exchanging assembly is formed by stacking graphite heat exchanging blocks, moreover, each heat exchanging block is provided with a deflection plate, the deflection plates and the inner wall of the heat exchanger cylinder body are sealed by forcedly deflecting and sealing piece. Accordingly, the block-hole-type graphite heat exchanger provided by the invention has the advantages that no gap exists between the deflection plate and the inner wall of the heat exchanger cylinder body, and no fluid streaming phenomenon happens during heat exchange so as to effectively improve the heat exchanging efficiency and ensure the heat exchanging effect. Through practice, compared with the conventional block-hole-type graphite heat exchanger, the block-hole-type graphite heat exchanger provided by the invention has a remarkable energy-saving effect, and can be used for reducing flow-transferring quantity by 15-20 percent, improving the equipment utilization rate by 15-20 percent and accordingly and effectively saving the heat exchanging area of the equipment.

Description

technical field [0001] The invention relates to a graphite heat exchanger, in particular to a block-hole graphite heat exchanger in which a seal is arranged between a baffle plate and the inner wall of a heat exchanger cylinder for sealing. Background technique [0002] At present, the commonly used block-hole graphite heat exchangers, especially the coolers with liquid cooling medium, whether graphite baffles or steel baffles, due to assembly requirements, there is always a gap between the graphite heat exchange block and the inner wall of the cylinder. There is a certain gap, which cannot effectively make the cooling medium achieve the purpose of complete deflection. During heat exchange, cross-flow phenomenon is inevitable, so the cooling effect is not ideal. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a forced baffle-sealed block-hole graphite heat exchanger, which is sealed by setting a seal between th...
