Cover plate 13.
Shown in Figure 2, heat-conductive body 11 has annular flange flange 113, lobe the most successively
112 and air inlet 111.Fig. 3 is the top view of heat-conductive body 11, as it is shown on figure 3, lobe 112
Helically wire, the lobe 112 of zigzag shape defines that two spirals for cooling media stream is logical lead to
Road 1121,1122 so that cooling medium starts outside from coil to coil from air inlet 111 and curls up circulation.In spiral shell
The lobe 112 of spin line shape takes up room little；Two helical ducts 1121,1122 add cooling
The circulation path of medium, beneficially cooling medium and heat-conductive body 11 fully carry out heat exchange, improve
The cooling effectiveness of cooling medium.There are in annular flange flange 113 114,6 installing holes of 6 installing holes
114 are preferably evenly distributed through in annular flange flange 113.Installing hole 114 is easy to heat-conductive body 11 and is installed to
On other devices to be cooled (such as radiation shield or electrode fixed plate).Annular flange flange 113 He
There is between lobe 112 hole 115,116, two location, wherein connect hole 115,116, location
Straight line is without the center of heat-conductive body 11.Heat-conductive body 11 is preferably by the metal (example of good heat conductivity
Such as copper) make.
Shown in Figure 2, the edge of generally round central dividing plate 12 have two breach 121,
122.Breach 121,122 part with helical duct 1121,1122 respectively aligns.At this
In embodiment, breach 121,122 outlet with helical duct 1121,1122 respectively aligns, from
And make cooling medium circulation path in helical duct 1121,1122 the longest.The skill of this area
Art personnel can join according to the temperature etc. that the flow of cooling medium and temperature, heat-conductive body 11 need to cool down
Number selects the size of breach 121,122, is not limited at this.The limit of central dividing plate 12
Also there is at edge the locating notch 123,124 aligned with hole 115,116, location.By middle interval
During plate 12 is placed on heat-conductive body 11, owing to connecting the straight line in hole 115,116, location
Without the center of heat-conductive body 11, if therefore by locating notch 123,124 respectively with location hole
115,116 alignment can realize breach 121,122 respectively with the outlet of helical duct 1121,1122
Align, it is to avoid assembling by mistake.Rigid material is used to make in flat central dividing plate 12, example
As rustless steel can be used to make, it is simple to be processed into ganoid tabular.

Air drain 132.The edge of central dividing plate 12 fits tightly with the edge of cover plate 13, central dividing plate 12
Breach 121,122 aligns with a part for air discharge duct 132, and steam vent 131 is by air discharge duct 132
It is connected with the breach 121,122 of central dividing plate 12, thus central dividing plate 12 and air discharge duct 132
Define the exhaust passage circulated to steam vent 131 for cooling medium from breach 121,122.
Seeing shown in Fig. 1 and Fig. 4, the heat exchanger 10 of the present invention also includes solid with heat-conductive body 11
The fixed air inlet pipe 14 connecting and being connected with air inlet 111, and fixing with cover plate 13 be connected and
The exhaustor 15 being connected with steam vent 131.Air inlet pipe 14 and exhaustor 15 are respectively used to and conveying
It is connected with the pipeline collecting cooling medium, it is to avoid cooling medium is at air inlet 111 and steam vent 131
Leak and cause unnecessary waste.Air inlet pipe 14 preferably employs the material identical with heat-conductive body 11
And one-body molded with heat-conductive body 11, exhaustor 15 preferably employs the material identical with cover plate 13 also
One-body molded with cover plate 13.
