The electric heat pipe in the electric heat pipe water-cooling resistor is directly immersed into water, and the electric heat pipe water-cooling resistor has the advantages of good contact, high heat transfer speed, high power and small size.
Description
Technical field
The utility model relates to a kind of electrothermal tube water-cooled resistor, is specifically related to a kind of resistor of small-volume large-power, belongs to electric and electronic technical field.
Background technology
The form of water-cooled resistor is varied at present, and it is too complicated that structure has, and some is too simple, directly on water pipe, does layer insulation, and around upper resistance wire, the insulation property of this way are lower, and performance is unreliable.The mode of water-cooled has: electricity separation, water power does not separate.Electricity separation cooling effect is slightly poor, but less demanding to water-cooling system, and the scope of application is wider; Water power does not separate good cooling results, but high to water-cooling system requirement, application scenario is few.
Summary of the invention
The technical problems to be solved in the utility model is to provide the electrothermal tube water-cooled resistor of the high and dependable performance of a kind of water-cooled effect.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of electrothermal tube water-cooled resistor, it is characterized in that, comprise aluminium shell, in aluminium shell, be provided with electrothermal tube, aluminium shell upside is provided with upper cover plate, and the left side of aluminium shell connects pagoda joint, the right side of aluminium shell is provided with cover plate, and the right side of electrothermal tube connects copper busbar.
Preferably, between described cover plate and aluminium shell, be provided with silicagel pad.

Compared with prior art, the utlity model has following beneficial effect:
1, in electrothermal tube water-cooled resistor of the present utility model, electrothermal tube is directly immersed in the water, and contacts, and heat transfer speed is fast, and power is high, volume is little.
2, under electrothermal tube water-cooled resistor overload impact condition of the present utility model, resistance to impact is good, and surface temperature is low, and the impact life-span is long, and when shock levels is accomplished 3.5g, electric property is unchanged.
3, electrothermal tube water-cooled resistor production efficiency of the present utility model is high, and scrappage is low;
4, the electrothermal tube of electrothermal tube water-cooled resistor of the present utility model is aspect electric property: insulation resistance value is large, and leakage current is low; Aspect production: all automations, production efficiency is high, and per day output is high, easily management and control.
5, the aluminium enclosure material of electrothermal tube water-cooled resistor of the present utility model adopts A3 aluminium, and A3 aluminium low price meets international standard ROHS aspect environmental protection.
Accompanying drawing explanation
The structural representation of the electrothermal tube water-cooled resistor that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
As shown in Figure 1, the structural representation of the electrothermal tube water-cooled resistor providing for the utility model, described electrothermal tube water-cooled resistor comprises aluminium shell 1, in aluminium shell 1, be provided with electrothermal tube 3, aluminium shell 1 upside is provided with upper cover plate 2, the left side of aluminium shell 1 connects pagoda joint 7, and the right side of aluminium shell 1 is provided with cover plate 5, and the right side of electrothermal tube 3 connects copper busbar 4.Between described cover plate 5 and aluminium shell 1, be provided with silicagel pad 6.
The preparation method's of above-mentioned electrothermal tube water-cooled resistor concrete steps are: electrothermal tube 3 is put into machine for shrinking and carry out the draw its inner each parts are fitted tightly, then electrothermal tube 3 is put into aluminium shell 1, cover upper cover plate 2, to between upper cover plate 2 and aluminium shell 1, by electron beam welding mode, interconnect, pagoda joint 7 is connected to the left side of aluminium shell 1, silicagel pad 6 is placed in to the right side of aluminium shell 1, covers cover plate 5, the right side of electrothermal tube 3 is connected to copper busbar 4.The material of described aluminium shell 1 is A3 aluminium.The R.DRB.1K00.0200.3490A (this electrothermal tube is sold on market) that electrothermal tube 3 is produced for Shanghai Ying Feng Electronic Science and Technology Co., Ltd..Electrothermal tube 3 is comprised of copper pipe, magnesium oxide, lectrothermal alloy wire, porcelain piece, eduction rod.Electrothermal tube 3 is put into machine for shrinking, through one draw technique, its pipe external diameter is diminished, can make like this between magnesium oxide and magnesium oxide, magnesium oxide and copper pipe, magnesium oxide and lectrothermal alloy wire almost very close to each otherly, the little heat conduction of thermal resistance is fast.
Electrothermal tube water-cooled resistor of the present utility model is tested according to GB5729 and IEC61373, in overload impact in short-term, insulation resistance, load life, resistance to vibration strength, is obviously better than traditional water-cooled resistor.
