Integrated self-reinforced and compact type one-time surface heat exchanging plate and flow channel structure formed by same

Abstract

The invention discloses an integrated self-reinforced and compact type one-time surface heat exchanging plate and a flow channel structure formed by same, the heat exchanging plate comprises a through-hole area, a fixing area, a stream guiding area, a marginal convex plate, and a heat exchanging area; the heat exchanging area is rectangle distributed with a concave shell and a convex shell of cone-shaped dome, the concave shell and the convex shell are distributed in rows to form a plurality of concave shell rows and convex shell rows parallel to the short sides of the rectangle, the concave shell rows and the convex shell rows are distributed on a base plate in an alternative manner, each concave shell and each convex shell respectively correspond to circular holes on the surface on which the base plate is located, the centers of the circular holes are distributed on a straight line parallel to the long sides of the rectangle, namely, all the convex shells and the concave shells are distributed in ranks. The flow channel is composed by overlaying of at least two heat exchanging plates. The heat exchanging plate of the invention has high compactness and small volume, can save metal consumption, and greatly improves heat transmitting coefficient; the structure is streamline, thus realizing small diameter of water conservancy and reducing the mechanical loss.

Description

technical field [0001] The invention relates to a primary self-reinforcing compact heat exchange plate suitable for various types of heat exchange equipment and heating equipment in military equipment, petroleum, chemical industry, refrigeration, metallurgy, energy and other industries.

Problems solved by technology

Anti-dust, anti-shock, and high stable heat transfer characteristics have always been problems; plate heat exchangers have the advantages of high compactness, small pressure drop, and superior vibration resistance. The literature data show that the fluid between the plates has a large disturbance at a lower flow rate, and the research on the self-reinforcing structure heat exchanger between the plates is obviously far from sufficient

[0003] Due to various reasons such as the limitation of the volume structure, the structure of the plate heat exchanger is generally very thin, and the packaging and inlay technology are mainly used. The fatal disadvantage is that the firmness of the enhanced heat transfer component and the surface of the substrate cannot be guaranteed. Poor contact, large thermal resistance, affecting heat transfer
