Abstract

This invention discloses an interleaved leaf vein shaped embedded microchannel heat exchanger, belonging to the field of heat exchangers. The heat exchanger has N inflow branches and N+1 outflow branches etched on the substrate, where N is greater than or equal to 2. There are multiple 45-degree bifurcations between the inflow and outflow branches. The heat transfer fluid flows into the N inflow branches, and after passing through multiple bifurcations, it converges and flows out through the N+1 outflow branches. Thus, this invention adopts a leaf vein shaped microchannel structure to reduce the microchannel space and improve heat dissipation efficiency.

Illustrated Guide

1. An interleaved leaf vein shaped embedded microchannel heat exchanger, characterized by: comprising N inflow branches and N+1 outflow branches etched on the substrate, where N is greater than or equal to 2, with multiple 45-degree bifurcations between the inflow and outflow branches. The heat transfer fluid flows into the N inflow branches and, after passing through multiple bifurcations, converges and flows out through the N+1 outflow branches.

2. The interleaved leaf vein shaped embedded microchannel heat exchanger according to claim 1, characterized in that each of the N inflow branches has multiple bifurcation nodes, where two bifurcation branches are split at each bifurcation node at a 45-degree angle to the inflow branch, connecting the adjacent bifurcation branches in the N inflow branches to form N-1 outflow branches. The bifurcation branches on both sides of the first and Nth inflow branches connect to form two outflow branches.

3. The interleaved leaf vein shaped embedded microchannel heat exchanger according to claim 1, characterized in that the substrate is made of diamond.

4. The interleaved leaf vein shaped embedded microchannel heat exchanger according to claim 1, characterized in that the width of the inflow and outflow branches is 0.5mm, and the width of the bifurcation branches is 0.71mm.
