Preferably, in order to prolong the time of cold-producing medium in shell body, the upper end of inner barrel and the welded top of shell body, the lower end of inner barrel and the bottom of shell body have gap (described gap is as much as possible little), offer first through hole on the sidewall of the lower end of inner barrel, the junction of cold-producing medium drain pipe and shell body is positioned at the projection of lower end on the bottom of shell body of inner barrel.Further preferred, the quantity of first through hole is two, and two first through holes relatively are arranged on the sidewall of inner barrel lower end.Further preferred, be welded with a base plate in the inner barrel, offer one second through hole on the described base plate; Described base plate is positioned at first through hole top.

The shape of above-mentioned shell body can be cylindric.

The shape of above-mentioned inner barrel can be cylindric.

The utlity model has following beneficial effect:

Being provided with in the space of shell body and the synchronous helical form flow deflector of water pipe that coils along inner barrel, is the helical form cavity with original circular cylinder spatial division, has prolonged the stroke of cold-producing medium in shell body, has strengthened the heat exchange effect.

The specific embodiment

Below, in conjunction with the accompanying drawings and the specific embodiment, the utility model is described further:

As depicted in figs. 1 and 2, a kind of pot type heat exchanger that has the synchronous screw flow deflector, the inner barrel 2 that it comprises airtight shell body 1 and is positioned at shell body 1.

Be connected with a helical form flow deflector 3 between shell body 1 and the inner barrel 2, the outer wall of the inwall of shell body 1, inner barrel 2 and helical form flow deflector 3 have been connected to form a helical form cavity 4.

The peripheral counter offer of described inner barrel 2 is wound with a water pipe 5, and described water pipe 5 is along the coil direction setting of helical form cavity 4, and the water side 51 of water pipe 5 is piercing in the top of shell body 1, and the water inlet end 52 of water pipe 5 is piercing in the bottom of shell body 1.

The outside of shell body 1 is provided with cold-producing medium feed tube 61, cold-producing medium drain pipe 62, and cold-producing medium feed tube 61 is communicated with the helical form cavity 4 on shell body 1 top, and cold-producing medium drain pipe 62 is communicated with the helical form cavity 4 of shell body 1 bottom.

The welded top of the upper end of inner barrel 2 and shell body 1, the bottom of the lower end of inner barrel 2 and shell body 1 has gap (described gap is as much as possible little), offer first through hole on the sidewall of the lower end of inner barrel 2, the quantity of first through hole is two, be respectively the first through hole a21, the first through hole b22, two first through holes relatively are arranged on the sidewall of inner barrel 2 lower ends.The junction of cold-producing medium drain pipe 62 and shell body 1 is positioned at the projection of lower end on the bottom of shell body 1 of inner barrel 2, that is to say, the cold-producing medium of bottom is just discharged by cold-producing medium drain pipe 62 after entering in the inner barrel 2 by first through hole.Be welded with a base plate 23 in the inner barrel 2, offer one second through hole 24 on the described base plate 23; Described base plate 23 is positioned at first through hole top.
