The specific embodiment
The version of the device of advocating
Heat-exchange device forms (Fig. 1) by a sheet part 1.It is by being crushed to.Described device has process gap 2 and 3, and (Fig. 2) welded in described gap subsequently.Heat-exchange device is made with the tubular body 4 of outer radial branch 5 and inner radial branch 6.The geometry of radially outer branch 5 and inner radial branch 6 is that the thermal balance that depends on specific device is passed through calculative determination.Tubular body in circumferential direction has identical longitudinal circular hole 7 (Fig. 3).Described device is designed to be arranged on the inside of casing 8 and by means of the securing member being positioned on the outer surface of tubular body, is fixed on casing 8 inside in having the outstanding part 9 of hole 10.Securing member is made into the form (Fig. 4) of the projection 11 at 12 places, edge.Described securing member can be different length and be (Figure 11) that make a plurality of positions on the outer surface of tubular body.The number of securing member is to select by calculating and depending on therein by the type of the casing of heat-exchange device.Described device provides at least three kinds of media by heat-exchange apparatus, for example, cooling medium 13, needs cooling operation medium 14 and 15, or heat carrier 13, needs the operation medium 14 and 15 etc. of heating.And need operation medium cooling or heating can have multiple and be different from medium 13 and in the passage of a plurality of formation, can be different.Inner radial branch 6 and outer radial branch 5 can be made into the taper from the substrate of branch to edge.They can be made with the sinusoidal shape of constant step-length 16 and amplitude 17.They can have the identical width from the substrate of branch 18 to edge.Described heat-exchange device can be arranged in circular casing 8 (Fig. 3) or in square casing (Fig. 5).The sinusoidal shape of outer radial branch 5 can You Cong branch substrate to variable amplitude and the step-length at edge, make.Different length 19 relative to each other can be made and at distance different distance place each other by the sinusoidal branch of outer radial, for example, and in the heat-exchange device in being fastened on square casing (Fig. 6).Outer radial branch 5 and inner radial branch 6 can make has complementary wavy projection 20 and 21 to increase the surperficial contact area of medium and heat-exchange device and to increase heat exchange (Fig. 7, Fig. 8).Longitudinally circular hole 15 is to make along the whole circumference of tubular body with distance equal distance each other.On the wall of longitudinal circular hole 15, thereby the inside guiding that can be formed in hole 15 increases the extra radially wavy projection 22 of the contact area of medium and heat-exchange device.The height of the radially outer branch 5 of making on the outer surface of tubular body can equal zero (Figure 11).Can use two or more devices simultaneously.For instance, four heat-exchange devices with the sinusoidal radial branching 5 in outside of different length are relative to each other fixed on (Fig. 9) in square casing, or eight heat-exchange devices with the sinusoidal radial branching 5 in outside of different length are relative to each other fixed on (Figure 10) in circular casing.
The length that depends on described heat-exchange device, medium can move in longer distance.
Described heat-exchange device is that (for example) is manufactured from aluminium by extruding, forms, to obtain the product of tool section form likely by shaping jig-suction nozzle in the lasting promotion of the high viscosity material of fusing.
Industrial applicibility
The operation of described device is as follows.
Described heat-exchange device is mounted in casing 8 and fixing by securing member 9,10,11,12.It is connected to operating equipment subsequently.Wall cooling or that thermal medium (for example) 13 passes the outer radial branch 5 of device spreads all over their length to be come cooling or heats them.Cooling or the heating that the outer wall of the outer radial branch 5 of device obtains is passed to the inwall of the branch of inner radial branch 6 of device.Heated or cooling, the inwall of the inner radial branch 6 of device will be trembled with fear or heat passes to medium 14 and 15.
Due to the cooling or heat medium of amount increasing and the contact area of the increase of medium and heat-exchange device, the design of described heat-exchange device is simply, cheaply and effectively.Described product is made into single-piece, and this has simplified the assembling of heat-exchange device and has brought the running cost reducing.
Therefore, solved the problem of configuration.
