Embodiment Construction
[0015] Such as figure 1 , figure 2 Shown: a water-cooled automobile rectifier bridge, which includes: a positive plate 7, a negative plate 2, a rectifier diode 6 and an annular plastic support 1. There are twelve rectifier diodes 6, six of which are installed on the positive plate 7, and the other six are installed on the negative plate 2. The positive plate 7 and the negative plate 2 are fan-shaped plates, and the two are connected by connecting bolts 12 and insulating spacers. The annular plastic support 1 is installed on the end faces of the positive and negative plates 7 and 2 through fixing bolts 5 . It is characterized in that: a cooling water channel I8 is made on the positive plate 7, a water inlet joint I9 is installed at one end of the cooling water channel I8, and a water outlet joint I4 is installed at the other end of the cooling water channel I8. A cooling water channel II14 is made on the negative plate 2, and one end of the cooling water channel II14 ...

The invention discloses a water-cooled automobile rectifier bridge, which relates to an automobile fitting. A cooling waterway I is manufactured on a positive plate, wherein one end of the cooling waterway I is provided with a water inlet joint I, and the other end of the cooling waterway I is provided with a water outlet joint I. A cooling waterway II is manufactured on a negative plate, whereinone end of the cooling waterway II is provided with a water inlet joint II, and the other end of the cooling waterway II is provided with a water outlet joint II. The water inlet joints I and II are connected with a water pump by a water inlet pipe I and a water inlet pipe II. The water outlet joints I and II are connected with a water tank by a water outlet pipe I and a water outlet pipe II. Cooling water can utilize own engine cooling water system of an automobile, and also can be independently arranged. The positive and negative plates are required to be insulated, and water is a conductor, so the two water inlet pipes cannot be supplied with water at the same time and the adjustment of a reversal valve is required to ensure that the other water inlet pipe does not have water when the water pump supplies the water into one water inlet pipe.
Description
technical field [0001] The invention relates to an automobile accessory, in particular to a water-cooled automobile rectifier bridge for an automobile generator. Background technique [0002] The automobile rectifier bridge is an important part of the automobile generator. The alternating current output by the generator is converted into direct current through the rectifier bridge, which is supplied to the electrical appliances in various parts of the automobile. The important component of the rectifier bridge is the rectifier diode. The rectifier diode bears a large current and generates a lot of heat. The heat dissipation problem of the automobile rectifier bridge is a key issue that restricts the service life of the rectifier diode. For the automobile rectifier bridges currently on the market, the method to solve the problem of diode heat dissipation is to increase the volume of heat dissipation, increase the heat dissipation holes, and expand the heat dissipation are...
