Abstract

An arched channel jacket comprises a deep plate used as the container wall, characterized in that one outside surface of the deep plate is covered with a corresponding thin plate, the deep plate and the thin plate are connected together by a plurality of parallel gap-distributed laser welding seams, and others thin plates in non-welding zone are inflated to form a plurality of arched channels in a continuous array manner. By using the utility model, the defect in prior technology can be eliminated, the product quality can be ensured, and the heat transfer efficiency also can be improved considerably. According to the demand, the utility model with built-in type or out-laid type structure can be processed. Additionally, each arched channel can be connected to form single-channel multi-course or multi-channel single-course passage to satisfy the production demand. Accordingly, the utility model has extensive application prospect.

Description

Jacket with arc-like channel

Technical field

The utility model relates to and a kind ofly can be used for evaporimeter, condenser, heater and cooler or be used for the heating of reactor, agitator or the heat-transferring jacket structure of cooling device, particularly a kind of heat-transferring jacket with arch shape passage.

Background technology

At present, more common in the heat-transferring jacket is a kind of half-pipe jacket, and it is earlier steel band to be processed into the halfpipe structure, also can obtain this halfpipe structure by the broken way into two of homogeneous tube; Again this halfpipe is weldingly fixed on outside the chamber wall, to form described jacket with arc-like channel.Adopt the chuck of said structure, can realize the purpose of heat transfer, but because the moulding process relative complex of semicanal structure, the making amount of getting up to work is bigger, and it is fixed by the inert gas-shielded arc welding method again, so that cause following defective: make that semicanal weld seam molten bath is roomy on the one hand, cause container inner wall significantly distortion to occur; Cause on the other hand between the own weld seam of itself and container to produce and intersects or overlapping phenomenon, the easy like this chuck medium that makes bleeds in the container, causes processing safety poor, and flaw detection requires height and is unfavorable for seam inspection; Simultaneously, the weld seam overlapping phenomenon also can cause the metal burning, and distortion strengthens, the drawback that thermal stress is concentrated.Moreover such structure can not make the spacing between the adjacent semicanal too little, otherwise more is difficult to guarantee weldquality, and obviously, the spacing distance between this semicanal will directly affect whole jacket structured heat-transfer effect.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at above-mentioned prior art, provides a kind of being convenient to make and the better jacket with arc-like channel of heat-transfer effect.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this jacket with arc-like channel comprises the slab as chamber wall, it is characterized in that: outside described slab one side, be coated with corresponding with it thin plate, fuse by the multiple tracks laser welded seam that distributes in the same way at interval each other between this thin plate and the slab, the thin plate of other non-weld zone is then formed continuously arranged a plurality of arcuate channels by bulging.

Described thin plate can be positioned at the inboard of slab and become built-in structure; Also thin plate can be positioned at outside the slab and become outlet structure.

Described multiple tracks laser welded seam with each other parallel be distributed as good.

In such scheme, described each arcuate channels can be end-to-end successively and be formed single channel multipass runner; Also can be parallel with one another and form multichannel one way runner.

Compared with prior art, because arcuate channels of the present utility model is by the laser weld that distributes in the same way at interval that thin plate and slab is fastening, bulging forms again, thereby eliminated the defective that the semicanal welding is brought in the prior art fully, and thin plate need not again to process in advance, so entire making process was both simple, can guarantee Forming Quality again; And each arcuate channels can also realize continuous distributed, thereby can improve heat-transfer effect significantly.Moreover, according to actual needs, can also be processed into built-in or outlet structure; Each arcuate channels can be connected into the runner of single channel multipass or multichannel one way in addition, produce needs so that satisfy.Thereby the utility model in actual applications, can obtain beyond thought effect, is worth applying in the prior art.

Description of drawings

Fig. 3 is the cross section structure schematic diagram after the bulging moulding among Fig. 2.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Fig. 1 is to shown in Figure 3, this jacket with arc-like channel comprises the slab of making of steel plate 1 and is positioned at the corresponding thin plate 2 in slab 1 outside, and the multiple tracks laser welded seam 3 by spaced and parallel distribution each other links into an integrated entity between this thin plate 2 and slab 1, and the edge of two plates also seals by Laser Welding, 2 of the thin plates of other non-weld zone by bulging form adjacent between continuously and a plurality of arcuate channels 4 that are arranged in parallel, as shown in Figure 1.

When making above-mentioned chuck, slab 1 is pasted tightly mutually with thin plate 2; Between two plates, produce the multiple tracks laser welded seam 3 that parallel longitudinal distributes by Laser Welding successively again and form a plurality of districts, as shown in Figure 2; Then, between two plates, feed the liquid that has certain pressure, in being that thin plate 2 in the non-weld zone is by inflation, until the yield point that surpasses thin plate 2 by ozzle 5; Eliminate hydraulic pressure at last, the non-weld zone of thin plate 2 finally for good and all is shaped to the arch shape passage, as shown in Figure 3.

During use, described each arcuate channels 4 can be end-to-end successively and be formed single channel multipass runner, and perhaps each arcuate channels 4 is parallel with one another and form multichannel one way runner.Like this, slab 1 chamber wall as equipment such as reactor, agitators is a vessel space in it, and thin plate 2 is as the chuck plate, and it is outer to be airspace then, and is connected with refrigerant or heating agent in the arcuate channels 4 between two plates.During work,, energy is passed to fluid in the vessel space, with the purpose that realizes conducting heat by refrigerant or heating agent flowing in arcuate channels 4.

Protection domain of the present utility model is not limited to the foregoing description; above-mentioned thin plate 2 also can be positioned at the inboard of slab 1; promptly can be with the heat-transfer surface of thin plate as equipment such as reactor, agitators; it in it vessel space; slab is as the tank wall of equipment such as reactor, agitator; it is outer then to be airspace, can save the chuck heat-insulation layer like this, and heat-transfer effect is also better.
