[0002] The spiral plate heat exchanger is a heat exchanger made of two parallel metal plates rolled into two spiral channels, and the heat exchange between hot and cold fluids is carried out through the spiral plate wall. There are two types of spiral plate heat exchangers: detachable and non-detachable. The spiral plate heat exchanger has the advantages of small size, compact equipment, high heat transfer efficiency and low metal consumption. It is suitable for dry liquid-liquid, gas-liquid, gas-gas convection heat transfer, steam condensation and liquid evaporation heat transfer, chemical, petroleum, medicine, machinery, electricity, environmental protection, energy saving and industries requiring heat conversion. However, the spiral plate heat exchanger with combined flow channels in the prior art cannot be effectively pressurized during use, so that it cannot flow quickly, reducing its circulation efficiency and use efficiency. Therefore, we propose a spiral plate heat exchanger with combined flow channels. Utility Model Content

[0005] According to the spiral plate heat exchanger with combined flow channels, the left and right sides of the inner shell are respectively connected with covers, and the two covers are respectively connected with conduits between the left tube body and the upper tube body and the right tube body and the lower tube body.
