Embodiment Construction

[0021] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 , figure 2 with image 3 As shown, the high-strength heat exchanger of this embodiment includes a cover plate 1 installed symmetrically up and down, and a plurality of heat exchange channels are installed between the cover plates 1. Between the plate 3 and the second partition 5, evenly arranged fins 4 are installed between the first partition 3 and the second partition 5, and seals 2 are installed at both ends of the fin 4, and are installed in the middle of the fin 4. There are "H" shaped ribs 6, "H" shaped ribs 6 adopt an integrated structure, the two sides of "H" shaped ribs 6 are in contact with fins 4 respectively, and the upper and lower end surfaces of "H" shaped ribs 6 are respectively connected to The first partition 3 and the second partition 5 abut; the "H" shaped rib 6 is installed in the middle of ...

Abstract

The invention relates to a high-strength heat exchanger. The high-strength heat exchanger comprises cover plates installed symmetrically up and down, and a plurality of heat exchange channels are installed between the cover plates. The heat exchange channels structurally comprise first partition plates and second partition plates arranged at intervals up and down, evenly arranged fins are installed between the first partition plates and the second partition plates, sealing strips are installed at two ends of the fins, H-shaped reinforcing ribs are installed in the middle of the fins and are of an integrated structure, two sides of the H-shaped reinforcing ribs respectively abut against the fins, the upper end faces and the lower end faces of the H-shaped reinforcing ribs respectively abut against the first partition plates and the second partition plates, and the H-shaped reinforcing ribs are installed right in the middle of the heat exchange channels. The high-strength heat exchanger is reasonable in structure and convenient to manufacture; by installing the reinforcing ribs in the middle of the fins in the heat exchange channels, the contact area of the fins and the partition plates is increased, the strength of the heat exchanger is enhanced, and the high-strength heat exchanger is high in bearing capability and long in service life.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a high-strength heat exchanger. Background technique [0002] A heat exchanger, also known as a heat exchanger, is a device that transfers heat from one heat-carrying medium to another. In industrial production processes, heating or cooling is often required, that is, heat transfer. When one fluid exchanges heat with another fluid and does not allow mixing, it is required to be carried out in a partition heat exchanger, which is used in chemical, petroleum, power, food and other industries. The main function of the heat exchanger is cold and hot Heat energy exchange between fluids. [0003] At present, aluminum plate-fin heat exchangers have been widely used, but in some high-pressure equipment environments, when the product needs to withstand high pressure, due to the small contact surface between the fins and the partition inside the heat exchange channel, it is easy ...
