Embodiment Construction

[0011] cold and hot fluids from figure 1 The A and B shown in the shell enter, and flow through the heat exchange zone 4 inside the square tube box 9 in a cross shape for heat exchange. The function of the Dg50 connecting flange 1, connecting bolt 2 and tube box flange 3 is to The tube box 9 and the tapered tube box 8 are fixed and sealed, and the heat exchange zone 4 is mainly composed of figure 2 The metal foam plate 10, the partition plate 11, and the baffle plate 12 are composed of the metal foam plate 10, the partition plate 11, and the baffle plate 12, and the cold and hot fluids are layered and sealed in multiple layers. The foam metal inside the foam metal plate 10 is through-hole, which can flow through the liquid medium fluid. The rear baffle plate 12 of the foam metal plate 10 is used to fix the foam metal plate 10 and prevent the high-pressure fluid from causing the foam metal plate 10 to deflect. shift. figure 1 Among them, the temperature measuring port 5...

Abstract

Aiming at the problems, such as large volume, great weight, high metal consumption, stable heat exchange parameter and the like, of the existing plate-type heat exchanger, the invention discloses a plate-type heat exchanger which is filled with foamed metals and can change the heat exchange parameter at any time according to technological requirements. According to the invention, by virtue of a method of filling modular foamed metals with various porosity factors between plate layers of the plate-type heat exchanger, the heat exchange performance of the plate-type heat exchanger is improved, so that the plate-type heat exchanger has the advantages of lowering the metal consumption and reducing the equipment volume on the premise of obtaining a same heat exchange effect; the heat-exchange equipment structure is compact and standard; and the heat exchange parameter can be changed through filling foamed metal materials with different porosity factors, so as to meet different technical heat exchange requirements.

Description

technical field [0001] The invention relates to a heat exchanger device, in particular to a plate heat exchanger. Background technique [0002] Heat exchange equipment is a general equipment widely used in chemical industry, oil refining, power, food, light industry, atomic energy, pharmaceutical, machinery and many other industrial sectors. [0003] With the progress of society, people have put forward higher requirements for heat exchange equipment. On the one hand, heat exchange equipment is required to have better heat exchange effect and save materials and be easy to produce and manufacture. On the other hand, it is required to meet different heat exchange parameters at the same time. requirements; application number: 200810033289.1 and application number disclose a finned tube heat exchanger lined with metal foam in the field of refrigeration technology, and improve the heat transfer performance in the heat exchange tube by filling foam metal. This kind of plate heat ...
