AI Technical Summary
The circular dielectric holes in existing heat exchangers are not perpendicular to the corrugated, resulting in unfast liquid flow rate and affecting the heat exchange efficiency.
The elliptical medium holes and arc -shaped grooves are used. The oval design of the medium holes allows the liquid to directly flow to the heat exchange channel. The arc groove and the medium holes are vertically vertically, which further ensures that the liquid flows into the channel directly.
It improves the flow rate of heat exchange medium, ensures the rapid and smoothness of the medium circulation, and enhances the efficiency of heat exchange.

Abstract
Description
Technical Field
[0001] The utility model relates to a heat exchanger with an elliptical medium hole plate. Background Art
[0002] The heat exchanger is a highly efficient and energy-saving heat exchange equipment with many advantages such as high heat transfer efficiency, light weight, small footprint, and easy maintenance. The heat exchanger is a highly efficient heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates.
[0003] The medium holes opened on the conventional heat exchanger plates are all circular, so as to facilitate the connection with the circular liquid pipeline. However, the circular medium hole is not perpendicular to the corrugation in the middle, which causes the liquid to collide and turn multiple times in the heat exchange channel, resulting in unsmooth passage and affecting the flow rate of the liquid. It is not suitable for use in some environments where the heat exchange medium needs to pass quickly. Utility Model Content
[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a heat exchanger with an elliptical medium hole plate which can increase the liquid flow rate and ensure fast and smooth medium flow.
[0005] The purpose of the utility model is achieved in this way:
[0006] A heat exchanger with elliptical medium hole plates, comprising stacked plates, with heat exchange channels formed between the plates, a front end plate being provided at the front end of the stacked plates, and a rear end plate being provided at the rear end, the front end plate and the rear end plate pressing and fixing the middle plate, medium through holes being provided at the same position on the plates, the medium through holes being respectively connected with the heat exchange channels on the plates, medium holes being provided at the four corners of the plates, the medium holes being elliptical, a plurality of connecting grooves being provided on the periphery of the medium holes, one end of each connecting groove being perpendicular to the edge of the medium hole, a herringbone corrugation being provided in the middle of the plates, an arc groove being provided between the herringbone corrugation and the connecting groove, one end of the arc groove being connected with the other end of the connecting groove, the other end of the arc groove being connected with the herringbone corrugation, and the arc section of the medium hole being directly opposite to the end of each arc groove.
[0007] The medium through holes are respectively connected with the heat exchange channels on the plates.
[0008] The outer end of the medium through hole is circular and connected to the external pipeline; the inner end of the medium through hole is elliptical and connected to the plate.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] The elliptical medium hole design of this heat exchanger with elliptical medium hole plate allows more liquid of the heat exchange medium to flow directly to the heat exchange channel; the design of the arc groove and the arc section of the medium hole being perpendicular allows the liquid to flow directly to the middle heat exchange channel, ensuring a higher flow rate of the heat exchange medium. In this way, the liquid flow rate can be increased to ensure fast and smooth flow of the medium. BRIEF DESCRIPTION OF THE DRAWINGS
