Abstract

The invention relates to a method for the continuous dyeing of warp ends, in particular cotton warp ends, with indigo or other dyestuff groups which, after impregnating and squeezing out, require oxidation or thermal treatment for fixing. The method eliminates the disadvantages of traditional methods for the continuous dyeing of warp ends. In particular, the required bath amount is considerably reduced by this method. By using a new dyeing reactor (1), the residence time of the warp ends in the dyeing installation can be varied without having to increase the bath volume. The option of heating or cooling the dyeing bath enables a fixing temperature between below room temperature and over 100 °C to be chosen. Optimal conditions can thus be created for all dyeing methods which are habitual for warp ends. In this way, the number of immersion-oxidation processes in the indigo dyehouse can be reduced and the growing demand for indigo blue jeans material with different wash resistances and shades can thus be catered for with increased flexibility. And the same can be done for black and coloured denim.

Description

Diode fixing structure of rectifier for ultimateizer {A DIODE FIXING STRUCTURE OF RECTIFIER FOR AN ALTINATOR}

The present invention relates to a diode fixing structure of the rectifier for the alternator, and more particularly, to a diode fixing structure of the rectifier for the alternator, which is capable of preventing a defect due to a change in soldering by pressing and fixing the diode.

In general, an automobile alternator (AC generator) is composed of a stator, a rotor, and a diode.When the ignition switch is inserted, a current of the battery flows into the rotor coil via a voltage regulator to generate magnetic lines, and then the engine starts to rotate the rotor. If the power generation occurs in the stator coil, three-phase alternating current is generated, and this three-phase alternating current is rectified by a diode. When the voltage at terminal B is higher than the battery voltage, the battery is charged immediately and current is supplied to each load. .

Such an alternator is used to charge an electric current and is typically provided with a rectifier. The rectifier includes a heat sink in which a plurality of heat dissipation fins are formed to dissipate and cool heat according to an operation of an electric device, as shown in FIG. 2. (1) is provided, and a diode (2), which is an electric element, is soldered and fixed to the heat sink (1) to constitute a circuit electrically.

However, the diode 2, which is assembled and fixed to the heat sink 1, is usually fixed by soldering, so that the soldered portion of the diode 2 is poor due to heat generated during operation or weakened durability due to long-term use. Or the solder is broken and released.

Therefore, the present invention has been invented to solve the above-mentioned problems in view of the above-described conventional problems, and it can be combined in one operation during assembly without bringing about deformation or durability caused by heat.

A characteristic implementation means for this is to form a knurling in the longitudinal direction on the inner circumferential surface of the insertion groove formed for inserting the diode into the heat sink, while also engaging the nuling formed on the inner circumferential surface of the insertion groove in the coupling end of the diode. The same shape of nuling is formed on the outer circumferential surface.

2 is a partial cross-sectional view taken along the line A-A of FIG.

<Explanation of symbols for the main parts of the drawings>

1: Heat sink 1a: Insertion groove

2: diode 2a: coupling end

Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a partial view showing a structure of a heat sink of a typical rectifier rectifier bar, as described above, the diode 2, which is an electrical element, is inserted into and fixed to the heat sink 1 constituting the rackifier. As shown in FIG. 2, a knurling is formed in the longitudinal direction on the inner circumferential surface of the insertion groove 1a formed to insert the diode 2 into the heat sink 1, and the coupling end of the diode 2 is formed. Also in (2a), the same type of nuling is formed on the outer circumferential surface thereof so as to engage with the nuling formed on the inner circumferential surface of the insertion groove 1a.

Therefore, when the diode 2 is inserted into the insertion groove 1a of the heat sink 1, the knurling formed at the coupling end 2a of the diode 2 becomes the insertion groove 1a of the heat sink 1. ) Is combined with each other and formed in the knurling ring is fixed.

After that, the soldering or connection for the electrical circuit configuration of the diode 2 is of course performed in a conventional manner.

The present invention as described in detail above, the heat sink and the diode is coupled to each other via a soldering-free kneading shape, so that it can be combined in one operation during assembly without causing deformation or degradation of durability due to heat It will work.
