Embodiment Construction

[0016] The built-in plate-shell heat exchanger of the welded plate of the present invention is a new type of heat exchange equipment designed on the basis of the prior art. Its plate is different, the corrugation on the plate is trapezoidal oblique corrugation 1, the inclination angle on both sides of trapezoidal oblique corrugation 1 is 45°, and the corrugation pitch is 15mm. A U-shaped notch 2 is provided in the center of one side of the plate, and a horizontal rib 3 extending to the corresponding side is provided at the symmetrical center of the U-shaped notch 2. On the other three sides 4 of the U-shaped notch 2 and the periphery of the plate, Set up welded edges separately. The two plates using the plates are relatively welded and crimped to the U-shaped notch 2, the horizontal rib 3 and the other three sides 4 around the plate by a seam welding machine, so that the three sides 4 are closed, and the U-shaped notch 2 is up and down. A pair of plates composed of two symmet...

Abstract

The invention discloses a built-in lamella heat exchanger of a welding plate in the field of heat exchange equipment. The heat exchanger is a rectangular sheet with trapezoid inclined grains. A U-shaped notch is arranged at the center on one side of the sheet, horizontal isolation ribs extending towards the corresponding side are arranged at the symmetrical center of the U-shaped notch, welding sealing edges are arranged on the other three sides on the periphery of the U-shaped notch and the sheet, a plurality of sheet pairs composed of the sheets, a water box and a pipe flange are welded to form a welding core body and fixed by a clamping plate, bolts and a fastening pulling plate. A U-shaped channel is formed in the sheet, the flowing channel length and the contact area with a medium are increased, and the heat exchange efficiency is effectively improved. Due to the fact that a chip body is integrally welded, a sealing gasket is not required to improve high temperature resistance, high pressure resistance and corrosion resistance, the sheet pairs are connected with the pipe flange through the water box, inner stress residue generated during welding of the pipe plate is reduced, cracking and deformation are avoided, and the heat exchanger has the advantages of being novel in conception, reasonable in structure design, stable in working performance, convenient to wash and maintain and suitable to be popularized.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a novel heat exchange device formed by a welded plate heat exchanger and a shell-and-tube heat exchanger. Background technique [0002] In the 1960s, plate heat exchangers were introduced into China from abroad, and it has been nearly 50 years. From scratch, from small to large, due to the continuous expansion of the application field of plate heat exchangers, various new plate heat exchangers continue to emerge, which are gradually accepted by people and sold well in domestic and foreign markets. Even so, there are still certain shortcomings and deficiencies. Those skilled in the art know that the sealing and pressure bearing of the heat exchanger is realized by the sealing gasket between the plates by the clamping force. Due to the limitation of the material of the sealing gasket, the It is also limited in terms of temperature and pressure. The NB / T47004-2009 standard stipulates that...
