Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 2 is the cut-open view of a kind of water-cooling structure for electric jigging platform moving coil provided by the utility model.The inner panel 5-01 of cooling wall 5 and moving coil framework 8 use High temp. epoxy resinses are bonding; Water guide pipeline 3 tops are fixedly connected on by screw thread in the outlet of water guide joint 1, and water guide joint 1 is embedded in the groove of moving coil framework 8 upper portion side wall, and is fixedly connected with by screw between water guide joint 1 and moving coil framework 8.Spout 2 screw threads are fixedly connected with in the entrance of water guide joint 1.Water guide pipeline 3 bottoms employing epoxy resin 7 are adhesively fixed on moving coil framework 8 bottom floors.Cooling wall 5 is whole cylindrical, moving-coil wire 4 circumferentially is wrapped in cooling wall 5 inside and outside both sides along cooling wall 5 on.For anti-stopper ring wire 4 comes off, use clip 6 chucking moving-coil wires 4.Spout 2, water guide joint 1, water guide pipeline 3, cooling wall 5 form complete water stream channel.Bubble in Fig. 2, Fig. 3, Fig. 4 in water stream channel 5-04 is chilled water.As extremely shown in Figure 7 in Fig. 2, chilled water is introduced by spout 2, flow through water guide joint 1, water guide pipeline 3 enters the flow inlet IN of cooling wall 5, tape loop is walked the heat that moving-coil produces in the water stream channel 5-04 of cooling wall 5, flows out by water export OUT, water guide pipeline 3, water guide joint 1, spout 2 at last.
As shown in Figure 3 and Figure 4, cooling wall 5 is made of inner panel 5-01, outside plate 5-02 and dividing plate 5-03, and inner panel 5-01 and dividing plate 5-03, dividing plate 5-03 and outside plate 5-02 adopt mode bonding or welding to seal, thereby form water stream channel 5-04.Also can directly dig out water stream channel 5-04 on the sidewall of inner panel 5-01, this sidewall is adjacent with outside plate 5-02; This moment, inner panel 5-01 was with outside plate 5-02 fits tightly and seal welding or bond together and do not need at this moment dividing plate 5-03.Cooling wall 5 is torus, and its import and export is as far as possible close, can simplify moving-coil structure like this, Fig. 5 be the cooling wall 5 of one-in-and-one-out around master, the left view of upper moving-coil wire 4, (in figure, arrow represents water stream channel 5-04).Moving-coil wire 4 is wound on the inboard and outside plate 5-02 of the inner panel 5-01 of cooling wall 5 outside, thereby the chilled water of circulation circulates at the middle water stream channel 5-04 of cooling wall 5 and carries out cooling to the wire 4 that generates heat.
As shown in Figure 6, can adopt the water-cooling structure of the mode of one-in-and-one-out to carry out cooling for the less middle-size and small-size electric vibration table of thermal value.As Fig. 6 and shown in Figure 1, for the water-cooling structure of one-in-and-one-out, spout 2, water guide joint 1, water guide pipeline 3 are two, lay respectively at flow inlet IN and the water export OUT place of cooling wall 5.
The water-cooling structure that as shown in Figure 7, can adopt two of multi-channel parallel to advance the mode of scene 2 for the larger big-and-middle-sized electric vibration table of thermal value carries out cooling.As Fig. 7 and shown in Figure 1, for two water-cooling structures that advance scene 2, spout 2, water guide joint 1, water guide pipeline 3 are four, lay respectively at two flow inlet IN1, IN2 of cooling wall 5 and two water export OUT1, OUT2 place.
The current import and export of above-mentioned Fig. 6 and two kinds of types of cooling shown in Figure 7 is all on cooling wall 5, abandoned traditional water-cooled and drawn the mode of tap on moving-coil wire 4, therefore can not be subject to the impact of shaking table structure and size, can be widely used in all kinds of electric vibration tables, also want simple a lot of than traditional type of cooling.After the processing criterion of cooling wall 5, its cost is also very low.
After this water-cooling structure assembling is completed, it is carried out the leakproofness test, guarantee this water-cooling structure nothing leakage infiltration phenomenon under the certain pressure certain hour.Moving coil framework 8 is installed in electric vibration table, is used in conjunction with power amplifier and signal source, open chilled water, switch on continuously more than 1 hour, carry out temperature test, cooling effect is fine; Then electric vibration table and power amplifier, charge amplifier, controller are used in conjunction with, the indices of this water-cooling structure is tested, well completed the requirement of electric vibration table, and serviceability is well reliable.
The above has done detailed description to the utility model in conjunction with the accompanying drawings and embodiments, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also make various variations under the prerequisite that does not break away from the utility model aim.The content that is not described in detail in the utility model all can adopt prior art.
