A contact heat exchange device

Abstract

The invention discloses contact type heat exchange equipment. The equipment comprises an annular pipe, wherein a sealing plate is fixedly connected to the left end of the annular pipe, a case is fixedly connected to the right end of the annular pipe, an annular water tank is arranged in the annular pipe, a water inlet pipe is fixedly connected to the upper end of the annular pipe, a water inlet hole is formed in the water inlet pipe in a penetrating mode, and the water inlet hole communicates with the annular water tank. According to the equipment, high-temperature fluid approaches static state by limiting flow of the high-temperature fluid flowing into and out of the annular pipe, so that the heat conduction effect of the fluid is improved, the contact surface with low-temperature gas isincreased through a tooth-shaped surface of a heat exchange ring, the heat exchange effect is improved, the low-temperature gas flows through reciprocating sliding of a sliding plate, heat exchange isaccelerated, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a contact heat exchange device. Background technique [0002] Heat exchange is the process of heat transfer between two objects or parts of the same object caused by temperature difference. Heat exchange is generally completed in three ways: heat conduction, heat convection and heat radiation. Heat conduction is when there is no macroscopic motion in the medium. Heat transfer phenomenon, which can occur in solid, liquid and gas, but generally only in solid is pure heat conduction, while fluid is generally in a flowing state, the heat exchange effect produced by heat conduction is not obvious, and even if the fluid is at rest state, wherein natural convection will also occur due to the density difference caused by the temperature gradient. Therefore, heat convection and heat conduction occur simultaneously in the fluid, but the heat exchange efficiency of the fluid is not high. A cont...

[0002] Heat exchange is the process of heat transfer between two objects or parts of the same object caused by temperature difference. Heat exchange is generally completed in three ways: heat conduction, heat convection and heat radiation. Heat conduction is when there is no macroscopic motion in the medium. Heat transfer phenomenon, which can occur in solid, liquid and gas, but generally only in solid is pure heat conduction, while fluid is generally in a flowing state, the heat exchange effect produced by heat conduction is not obvious, and even if the fluid is at rest state, wherein natural convection will also occur due to the density difference caused by the temperature gradient. Therefore, heat convection and heat conduction occur simultaneously in the fluid, but the heat exchange efficiency of the fluid is not high. A contact heat exchange device set forth in the present invention , can solve the above problems
