As shown in Fig. 2, insulation cooling unit is installed on the gap in frequency converter between adjacent heating electric appliance element, including
Heat-conducting insulation material layer 2 and sealing poly-bag 1, wherein sealing 2 water inlet 3 of poly-bag and water outlet 4 are integrated and prolong with sealing poly-bag 2
It reaches other than cabinet, is connect with circulation；Seal 2 periphery of poly-bag with heat-conducting insulation material layer 1 (can according to and pressure request
Equipment multilayered thermally-conductive insulation material layer 1).Sealing poly-bag water inlet and water outlet position other than cabinet are equipped with water nozzle.
Using the serial Heat Conduction Material of Sil-Pad 900 as heat-conducting insulation material layer 2, smooth surface has the present embodiment
The insulating properties of high-termal conductivity, breakdown voltage 4500V.When production, two layers of heat-conducting insulation material layer can be pasted on outside sealing poly-bag,
Pressure resistance is placed in the gap between heating electric appliance element together close to 9000V, can be in two sides heating electric appliance member after water-filling swelling
Under the extruding of part (such as large capacitor), so that heat-conducting insulation material layer is tightly attached to the electrical member outboard of fever, by sealing poly-bag
Cold water effectively heat is guided.
The specification of sealing poly-bag is separately designed according to the space of cabinet, and using customized product, the part in cabinet is whole
Body seals poly-bag, can bear certain water pressure, also without any leak source, guarantees using safe.
When first used, the sealing poly-bag with heat-conducting insulation material layer being first suitble to specification is by flat sided direction
(as shown in Figure 3) is placed in the gap between heating electric appliance element, and is hung by lifting rope in this position, is passed through recirculated water (20
DEG C or less), poly-bag swell is sealed, until being tightly attached between heating electric appliance element, checking that surface is anhydrous can come into operation, and such as scheme
Shown in 4.
When disassembly, water pump stops, and the water row in circulating water line is rushed down；Close the entery and delivery port water nozzle of sealing poly-bag
3,5 (other than cabinet), then integral demounting fall water pipe connected to it, by taking out in cabinet.
Temperature-sensitive unit uses thermochromic patch 8, is attached on frequency-charger cabinet internal heat generation electric elements shell.The present embodiment
In, using NCW series reversible thermochromic patch, there is colour changing thermal indicutor, number display and the reversible function of become color, itself
With adhesive sticker, applied to frequency converter, capacitor 7 shell on, for monitoring the temperature of electrical component shell.Once supervising temperature portion
Position temperature meets or exceeds the rated temperature of thermometric patch, and thermochromic patch is reddened color by black immediately, and in thermometric patch
