Lattice type heat exchanger

Abstract

The invention relates to a heat exchange structure, and provides a lattice type heat exchanger. The lattice type heat exchanger comprises a bottom plate (3), a first fluid passage and a second fluid passage, wherein a lattice type dividing fluid (4) is arranged on the bottom plate (3); the first fluid passage is used for conveying a high viscosity fluid, and the first fluid passage comprises a first fluid inlet (11) and a first fluid outlet (12); the second fluid passage is used for conveying a low viscosity fluid, the second fluid passage and the first fluid passage are arranged in an upper and down mode, and the directions are interlaced; and the lattice type dividing fluid (4) ranges from the first fluid inlet (11) to the first fluid outlet (12), and is alternately dividing and intersecting the incoming first fluid. The lattice type heat exchanger is more uniform in heating and reaction of the fluid.

Description

technical field [0001] The present invention relates to a heat exchange structure, more specifically, to a lattice heat exchanger. Background technique [0002] The microchannel heat exchanger has a high specific surface area, a large heat exchange area, and high heat exchange efficiency, and can achieve heat exchange effects in a short time. However, due to the small size of the microchannel, the pressure loss is relatively large when the fluid flows through it. When the viscosity of the fluid is very high, the pressure drop will be so large that the fluid machine cannot provide enough pressure for the fluid to flow, that is, the microchannel heat exchanger fails. In order to achieve the purpose of heating high-viscosity fluid, it is usually heated directly in the tank reactor, that is, the purpose of continuous production cannot be achieved. [0003] In order to achieve continuous production, traditional casing or plate heat exchangers are generally used to heat high-vis...

Problems solved by technology

However, resistance heating can easily cause the temperature gradient in the fluid to be too large, resulting in excessive local heating of the fluid near the pipe wall and rapid temperature rise, which will carbonize part of the resin during the heating process and damage chemical production.
