The utility model is reasonable in structure, high in reliability and stability, high in power and long in service life.
Description
Technical field
The utility model relates to a kind of water-cooled resistor.
Background technology
The structure of existing a kind of water-cooled resistor is: main body adopts hollow porcelain tube, is wound with alloy resistance wire on porcelain tube, and alloy resistance wire is externally coated with insulating varnish, and the two ends of porcelain tube are provided with the lead that joins with alloy resistance wire, and a copper pipe is by hollow porcelain tube.The main deficiency that the resistor of this structure exists is: dielectric voltage withstand is low, belongs to nonisulated type resistor; The sealing reliability of resistor insulating barrier is not high, uses or uses in adverse circumstances the insulating varnish of alloy resistance wire outside, back to ftracture or to come off for a long time, and then cause naked leakage of alloy resistance wire and accelerated oxidation, and the reliability and stability of resistor are descended; This in addition water-cooled resistor is not easy to install, and its vibration resistance and impact resistance are also relatively poor.
The utility model content
The purpose of this utility model is to provide a kind of water-cooled type resistor with aluminum shell, its reliability and stability height, and volume is little, power is big.
For achieving the above object, the utility model adopts following scheme: water-cooled type resistor with aluminum shell, passed cold water pipe in one porcelain tube, be wound with alloy resistance wire in the porcelain tube outside, be provided with the lead that joins with alloy resistance wire at the two ends of porcelain tube, porcelain tube is contained in the shell of an aluminium matter together with the alloy resistance wire on it, between shell and porcelain tube, be filled with the silicone molding compound, between porcelain tube and cold water pipe, be filled with the silicone molding compound, the two ends of cold water pipe and lead extend outside the shell, are provided with some spaced apart fin on the outer surface of shell.
The water-cooled type resistor with aluminum shell that the utility model provides is when work, the one, can realize outside good heat radiation by aluminum shell, the 2nd, guaranteeing in cold water pipe has cooling water flow out-of-date, can realize the heat radiation that it is inner good, realized the good heat radiating of this two aspect, its power can improve greatly; Be filled in the silicone molding compound that reaches between porcelain tube and the cold water pipe between shell and the porcelain tube and also have better heat-resisting and thermal conductivity, therefore the power that improves the inner and outside radiating effect of resistor, raising resistor is also had help, and the integral die type structure that filling constituted of silicone molding compound can improve the vibration resistance and the resistance to impact of resistor.In addition, the sealing of this water-cooled type resistor with aluminum shell is better, and the ability that humidity, salt spray resistance, high-low temperature resistant impact improves greatly, and can prevent the aging of alloy resistance wire effectively.
The utility model is rational in infrastructure, the reliability and stability height, and power is big, long service life.
