Novel circular hole heat absorption sheet for heating stove and heating stove

Abstract

The heat absorption sheet comprises a heat absorption sheet body, a plurality of round flanged holes are evenly formed in the heat absorption sheet body in the length direction of the heat absorption sheet body, a convex hull is arranged between every two adjacent round flanged holes, and a convex hull is arranged on the outer side of the round flanged hole on the outermost side. The center hole is designed to be a round hole, the overall width of the heat absorption piece is reduced, the turnup and convex hull structures are added, the heat absorption effect the same as that of an oval hole is achieved, and the convex hulls in the middle of the round turnup hole and the convex hulls on the two sides of the round turnup hole facilitate turbulent flow of smoke and local heat storage. The turnup structure is beneficial to blocking smoke and changing the flowing direction of the smoke, so that the smoke can flow towards the round turnup. The heat absorption effect of the whole main heat exchanger is achieved, materials can be reduced, cost can be saved, and meanwhile the manufacturing and assembling precision can be better guaranteed.

Description

Technical field [0001] The present invention belongs to the field of heating furnace heat exchangers, specifically, relates to a new type of heating furnace with a new round hole heat absorbing sheet and heating furnace. Background [0002] The existing heating furnace high power (more than 35kW) with the main heat exchanger heat absorber, in order to increase the heat absorption effect, most of the middle is an elliptical hole design, by increasing the width of the heat absorbing sheet to increase the heat absorption area, used to meet the main heat exchanger heat absorption effect of the whole machine. However, such heat absorbing sheets have the following defects: 1, the size of the elliptical hole with flanging is difficult to control, it is difficult to ensure the production assembly gap, affecting the performance of the product; 2, the heat absorption sheet width is large, the material usage is large, and the cost is high. [0003] In view of this, the present invention is ...
