Abstract
A heat exchanger comprises a first heat-exchanging tube module, a second heat-exchanging tube module and a ripple compensator. The heat exchanger has the advantages that due to the fact that the one end of the first heat-exchanging tube module is connected with one end of the second heat-exchanging tube through the ripple compensator, displacement of heat-exchanging tubes due to reasons such as expansion caused by heat and contraction caused by cold is adjusted through the ripple compensator, and the service life of the heat-exchanging tube is prolonged; an end port turnup of a first heat-exchanging tube is connected with a first tube plate through a nut, and an end port turnup of a second heat-exchanging tube is connected with a second tube plate through a nut, so that connection between the heat-exchanging tubes and the tube plates is firmer and sealing performance of the heat-exchanging tube is better; and the first heat-exchanging tube is a heat-exchanging tube made of glass fiber reinforced poly tetra fluoro ethylene, and the second heat-exchanging tube is a heat-exchanging tube made of glass fiber reinforced poly tetra fluoro ethylene, so that the strength of the heat exchanging tubes is improved and heat-exchanging efficiency is improved.
