Problems solved by technology

[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 to Separation by bursting, resulting in product leakage

Embodiment Construction

[0019] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0020] like figure 1 , figure 2 and 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 reinforcing ribs 6, and the structure of reinforcing ribs 6 is: comprising a vertical rod 7, one end of the vertical rod 7 extends with a parallel branch rod 8 perpendicular thereto, the other end of the vertical rod 7 and the end surface of the branch rod 8 They abut against the fins 4 respectively, and the outer ends of the upper and lowe...

Abstract

The invention relates to a high-strength heat exchanger which comprises cover plates arranged vertically and symmetrically, and a plurality of heat exchanging channels are arranged between the cover plates. The heat exchanging channels structurally comprise first partition plates and second partition plates which are arranged vertically at intervals. Fins distributed evenly are arranged between the first partition plates and the second partition plates, sealing strips are arranged at two ends of the fins, and reinforcing ribs are arranged in the middles of the fins. The reinforcing ribs structurally comprise vertical rods, one end of each vertical rod extends to form a branch rod perpendicular to the vertical rod, the branch rods are parallel, the other ends of the vertical rods and the end faces of the branch rods butt against the fins, and the outer ends of the upper branch rods and the lower branch rods butt against the first partition plates and the second partition plates respectively. The high-strength heat exchanger is reasonable in structure and convenient to manufacture, increases contact area between the fins and the partition plates by arranging the reinforcing ribs in the middles of the fins in the heat exchanging channels, improves the strength accordingly and is large in load bearing performance 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 ...
