Problems solved by technology

[0007] The disadvantage of this conventional embodiment is that the flow of the second fluid through the central chamber will cause the baffle to move, and since the baffle must be restricted from moving, the screw and spacer must be made of very thick material
[0008] Using a large amount of material will obviously make the material cost high
[0009] Another disadvantage is the laborious and costly assembly of such tube heat exchangers due to the laborious installation of the baffles
[0011] Another disadvantage is that the material used for the screw and spacer is different from the material used to make the baffles, so logistical costs are higher

Embodiment Construction

[0027] figure 1 A tubular heat exchanger 1 according to the invention is schematically shown, essentially comprising a closed housing 2 which is divided by end plates into three chambers 4 to 6, the central chamber 4 and two cavities 5 and 6 on both sides of the central cavity, and the end plate is a structure of two parallel partitions 3 .

[0028] A central chamber 4 is located between said partitions 3 in which passages 7 are provided through which parallel pipes 8 extend.

[0029] The other two chambers 5 and 6 on both sides of the central chamber 4 are connected by the above-mentioned tube 8, more specifically, the chamber 5 forms the input part for the first fluid, and the chamber 6 forms the output part for the first fluid .

[0030] The central cavity 4 has an inlet 9 and an outlet 10 for the second fluid, and a baffle 11 positioned transversely with respect to the longitudinal direction of the tube 8 .

[0031] The structural form and relative position of the baffl...

Abstract

Tube heat exchanger for exchanging heat between two fluids, a first and second fluid respectively, consisting of a housing (2) wherein one or more tubes (8) extend between an inlet part (5) and an outlet part (6) for the first fluid, and whereby these tubes extend through passages (13) through baffle plates (11) which are secured at a distance from one another by means of one or more fastening means, whereby said fastening means comprises a profile (14) that is snapped in place in one or more recesses (19) in the respective baffle plates (11), characterised in that the profile (14) is a V-profile and the recess (19) is a V- shaped recess having protrusions (23) on its two opposite edges (22) behind which the V-profile (14) is snapped in place.

Description

technical field [0001] The present invention relates to tubular heat exchangers. Background technique [0002] There are some known tubular heat exchangers for exchanging heat between two fluids, a first fluid and a second fluid, the heat exchanger comprises a shell in which one or more tubes extend , the ends of the tube are fixed to a partition that divides the housing into three chambers, specifically an input chamber and an output chamber for the first fluid, and a central chamber located between the input chamber and the output chamber, The central lumen has an inlet and an outlet for the second fluid. [0003] In a conventional heat exchanger, one or more baffles are arranged transversely to the direction of the tubes, and the tubes pass through channels in these baffles to direct the flow of the second fluid in a certain way. [0004] Traditionally, the baffles are arranged such that the channels for the second fluid are arranged alternately on one and the opposite ...
