AI Technical Summary
Technical Problem
In existing oil heat exchangers, the flow rate of lubricating oil or cooling medium is uneven when entering the fluid channel, which is exacerbated, especially when two-phase flow is present, thus affecting the heat exchange efficiency.
Method used
An isolator and a flexible membrane are set in the excitation structure of the heat exchange plate to form a periodically reciprocating jet to uniformly distribute the fluid flow rate, and bubbles are separated by a self-excited tube and a cyclone separator to prevent bubble collapse.
Benefits of technology
This achieves uniform distribution of fluid within the heat exchange plate, enhances heat exchange efficiency, ensures safe and reliable operation of the lubricating oil heat exchanger, and extends its service life.

Abstract
本发明涉及换热器技术领域，提供一种换热板及滑油换热器。上述的换热板包括：板体、第一封头和激励结构，板体设有多个第一流道；第一封头与板体的第一端连接，第一封头与多个第一流道连通；激励结构设有依次连通的进口、空腔和出口，空腔的宽度大于进口的宽度，出口与第一封头连接，激励结构包括隔离体，隔离体设置于空腔内，隔离体与空腔的内壁之间形成第二流道，第二流道与进口以及出口连通。上述的换热板，可在流体进入空腔内后，在激励结构的出口处形成周期性往复摆动的射流，以将流体喷射至第一封头的各个位置，进而进入换热板的各个第一流道内，实现了第一流道内流体流量均匀分布，通过流体脉动，能够反复破坏传热边界层，增强了换热效果。
