Description

(5k) HEAT EXCHANGER

I

The invention relates to spiral heat exchangers and can be used in the food and chemical industries.

According to the main author, No. 37044., a heat exchanger is known, comprising a housing with corrugated sheets placed inside, folded into a spiral and forming channels for circulating coolants, with corrugations arranged across the sheet f1.

The disadvantage of this heat exchanger is the possibility of deformation of the corrugated sheets due to the difference in pressure of the coolants flowing around them, which causes an increase in the thickness of the sheets and, consequently, an increase in the metal capacitance.

The purpose of the invention is to reduce metal consumption.

This goal is achieved by installing spacing pins located between the corrugated ligatures.

at a distance, t-ko times the width of the channels.

FIG. 1 schematically shows a heat exchanger; Fig 2 is a section A-A in Fig. 1.

The heat exchanger includes a housing 1 with corrugated sheets 2 and 3 placed inside. Coiled into a spiral and forming channels k and S for circulating coolants, while the corrugations 6 are located across sheets 2 and 3 and between them spacer pins 7 are located one from another They are + -40 times higher than the width of the channels and 5 The pins 7 are mounted on flat sections 8 made on the corrugations 6 sheets 2 and 3- The heat exchanger is also equipped with fittings 9-12 for supplying and discharging coolants. The pins 7 perceive the power loads arising due to the pressure difference between the heat transfer fluids circulating through channels 4 and 5, as a result of which the sheets
