The heat transfer of interior outside is also uneven, causes heat exchanger effectiveness low, the problems such as heat-transfer effect difference.
Utility model content
For the problems referred to above, this utility model provides a kind of bushing type preheater, using multilayer sleeve structure, it is ensured that cooling
The interior outside of water is heated evenly, and improves flow velocity, improves heat-transfer effect.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, this utility model is achieved through the following technical solutions：
A kind of bushing type preheater, including the thermal fluid inlet and coolant outlet that are arranged on top, is arranged on bottom
Hot fluid outlet ports and cooling water inlet, between the thermal fluid inlet and hot fluid outlet ports, and cooling water inlet and cooling water
It is connected by sleeve pipe between outlet, it is characterised in that described sleeve pipe includes concentric interior-heat fluid hose, cooling water from inside to outside
Pipe and exterior-heat fluid hose, the two ends of cooling water pipe are connected with coolant outlet and cooling water inlet respectively, interior-heat fluid hose with
The two ends of exterior-heat fluid hose are connected with thermal fluid inlet and hot fluid outlet ports respectively.
It is preferred that, described sleeve pipe is in the shape of a spiral.
Or, described sleeve pipe includes several horizontal connection tubes be arrangeding in parallel, the two ends of several horizontal connection tubes
It is connected by U-shaped connecting tube.
It is preferred that, the material of described sleeve pipe is steel pipe.Wherein, the interior-heat fluid hose, cooling water pipe and exterior-heat fluid hose
Diameter ratio is 1：2：3.
The beneficial effects of the utility model are：The interior outside of cooling water pipe is respectively provided with interior-heat fluid hose and exterior-heat fluid
Pipe, it is ensured that the interior outside of cooling water is heated evenly, in addition, cooling water is discharged from bottom sleeve pipe, top, and hot fluid is from top
Portion's sleeve pipe, bottom are discharged, and become cross-flow shape respectively with cooling water, improve flow velocity, improve heat-transfer effect.

7 two ends are connected with thermal fluid inlet 1 and hot fluid outlet ports 3 respectively.
It is preferred that, described sleeve pipe is in the shape of a spiral.
Or, described sleeve pipe includes several horizontal connection tubes be arrangeding in parallel, the two ends of several horizontal connection tubes
It is connected by U-shaped connecting tube 8, as shown in figure 1, the quantity of the horizontal connection tube is 5, and passes through 4 U-shaped connecting tubes 8
It is connected.
In order to improve heat transfer efficiency, the material of described sleeve pipe is steel pipe.Preferably, the interior-heat fluid hose 5, cooling water pipe 6
Diameter ratio with exterior-heat fluid hose 7 is 1：2：3.
The interior outside of cooling water pipe is respectively provided with interior-heat fluid hose and exterior-heat fluid hose, it is ensured that receive in the interior outside of cooling water
Hot uniform, in addition, cooling water is discharged from bottom sleeve pipe, top, and hot fluid is discharged from top sleeve pipe, bottom, point
Do not become cross-flow shape with cooling water, improve flow velocity, improve heat-transfer effect.
Preferred embodiment of the present utility model is these are only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure made using this utility model description and accompanying drawing content or equivalent flow conversion, or directly or indirectly transport
Used in other related technical fields, it is included in the same manner in scope of patent protection of the present utility model.
