Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
The present invention mainly comprises shell 1, cover plate 6, is wound with bobbin 7,2 electrodes of resistive conductor.Be explained respectively below.
Figure 1 shows that shell 1 schematic diagram, described shell 1 housing has certain thickness, is provided with water inlet 2, delivery port 3 in a side or different sides.Dug water channel 5 in shell 1 housing, described water channel 5 two ends are connected with water inlet 2, delivery port 3, and in Fig. 1, arrow is depicted as water (flow) direction.Water channel 5 is in 1 or multiple U-shaped bending in shell 1 housing, and the series connection of each U-shaped water channel is parallel.It should be noted that, the number of U-bend song should adapt with bobbin number 7, to reach better water-cooled effect, preferentially, fixes a bobbin 7 above each straight line portion of U-bend song.
Described shell 1 inboard is also provided with two grooves, and for assembling the electrode of resistor, described electrode is communicated with the external world by screwed hole, the preferred stainless steel electrode of described electrode.
Figure 2 shows that cover plate 6, size is consistent with shell 1, for can 1.
Fig. 3 is bobbin 7 vertical view. described bobbin 7 is the insulation boards with mechanical strength.As can be seen from Fig. 4, bobbin 7 two sides is symmetrical arranged 7 protrusion row, and each protrusion is in the same size.Protrusion columns and the protrusion number often arranged can be arranged as required.The protrusion of the present embodiment has 4 row.
Fig. 5 is the single vertical view being wound with the bobbin 7 of resistive conductor 8, as can be seen from the figure, the stretching bar of resistive conductor 8 is parallel U-shaped coiling along all protrusion row of bobbin 7 one side, identical coiling is carried out around to another side after one side coiling completes, after coiling completes, resistive conductor 8 two ends are connected to electrode.
In real process, the number of bobbin 7 can resistance value as required be arranged.When for winding mode time two or more as shown in Figure 6: each bobbin has the face opposed juxtaposition arrangement of protrusion, after the winding of previous bobbin 7, directly carry out the coiling of next bobbin 7, after whole coiling, bobbin 7 arranges and is just assembled into shell 1 to the mode of shell 1 with side, and available terminal 4 is fixed, resistive conductor 8 two ends and electrode welding, then cover plate 6 covers shell 1 and seals.
When the present invention works, first logical cooling water, then connect resistor, cooling water enters from water inlet 2, goes out from delivery port 3 through parallel series water channel 5, the heat produced when taking away resistor work.
Processing method of the present invention is as follows:
1, make the shell 1 with parallel series water channel 5 and cover plate 6: processing mold, inject shell 1 and cover plate 6 with grinding tool;
2, bobbin 7 is processed;
