TL;DR: In this article, a countercurrent plate fin type heat exchanger is proposed to improve heat exchange efficiency while minimizing increase in pressure loss, where plates 22 and corrugated plate-shaped heat transfer fins 23 are alternately laminated at a plurality of stages and fluid flow passages 1c, 1e where gas is made to flow are constituted between the plates 22, 22 at each layer.
Abstract: PROBLEM TO BE SOLVED: To provide a countercurrent plate fin type heat exchanger improving heat exchange efficiency while minimizing increase in pressure loss. SOLUTION: In the countercurrent plate fin type heat exchanger, plates 22 and corrugated plate-shaped heat transfer fins 23 are alternately laminated at a plurality of stages, and fluid flow passages 1c, 1e where gas is made to flow are constituted between the plates 22, 22 at each layer. The fluid flow passage at each layer is alternately divided into a high-temperature fluid flow passage 1e where high-temperature fluid is made to flow and a low-temperature fluid flow passage 1c where low-temperature fluid is made to flow, and the flowing directions of the high-temperature fluid flow passage 1e and the low-temperature fluid flow passage 1c oppose to each other. The shapes of the heat transfer fins 23 are set to be different between the high-temperature fluid flow passage 1e and the low-temperature fluid flow passage 1c. COPYRIGHT: (C)2010,JPO&INPIT

TL;DR: In this article, a double canister countercurrent heat exchanger sets up on wet of the heat supplying, not only it can collect the heat, but also it can get water for the bathe, especially the low temperature heat supplying citizen can have bathe.
Abstract: A double canister countercurrent heat exchanger sets up on the wet of the heat supplying, not only it can collect the heat, but also it can get water for the bathe, especially the low temperature heat supplying citizen can have bathe, the higher can prevent the deposit forming. It includes left and right canister, where there is separately hot air inlet, outlet, water inlet and outlet. There is water heat absorbing pipe, one end of which connects to the water inlet. There is heat supplying pipe, one part of which connects to the hot air inlet, and the left and right canister is through by the heat supplying pipe. The water heat absorbing pipe connects to the cavity of the right canister. This heat exchanger configures the countercurrent structure. The material of the heat supplying pipe is stainless steel; it saves the Copper pipe in the original pipe and the material, the cost of which is low. This invention adopts hot and cold fluid exchanging to solve the water deposit, and it also can improve the temperature of the hot water.
