Abstract
The utility model discloses an outboard engine rectifier heat abstractor, which comprises a rectifier shell and an outboard engine; the rectifier shell is mounted on the surface of the engine; the surface of the engine is provided with a diversion hole at the position of the rectifier shell, and the diversion hole is communicated with a cooling water channel in the engine, so that cooling water of the engine flows through the surface of the rectifier shell. A sealing steel gasket is also arranged between the rectifier shell and the surface of the engine to prevent water leakage. The plane of the engine, on which the rectifier is arranged, is made into the diversion hole and is communicated with the water channel, so that the rectifier shell is directly contacted with cooling water, when the cooling water flows through the rectifier shell, a large amount of heat can be taken away, meanwhile, the heat is dissipated to the air through the rectifier shell, and the two heat dissipation modes are overlapped, so that the heat dissipation effect is doubled, and the normal operation of the rectifier under high current is ensured.
Description
Technical Field
The utility model relates to the field of outboard engine heat dissipation. In particular to a radiator of an outboard engine rectifier.
Background
The current is higher when the outboard engine rectifier works, the problem of large heat productivity exists, and the current can not exceed 7A through the heat dissipation of the aluminum alloy shell of the general rectifier. As shown in fig. 1, the aluminum alloy housing of the conventional rectifier is fixed to the engine surface by bolts. For some outboard engines, the current of the rectifier is large and can reach 35A, and the heat dissipation of the shell alone cannot meet the requirement.
Disclosure of Invention
The utility model aims at: the heat radiator for the outboard engine rectifier is characterized in that water cooling is added on the basis of heat radiation of the shell, and the temperature of the rectifier can be controlled within 90 degrees, so that the temperature requirement of the rectifier is met.
The technical scheme of the utility model is as follows:
an outboard engine rectifier heat sink includes a rectifier housing and an outboard engine; the rectifier shell is mounted on the surface of the engine; the surface of the engine is provided with a diversion hole at the position of the rectifier shell, and the diversion hole is communicated with a cooling water channel in the engine, so that cooling water of the engine flows through the surface of the rectifier shell.
Preferably, a sealing steel gasket is also arranged between the rectifier shell and the surface of the engine to prevent water leakage.
Preferably, the diversion holes on the surface of the engine are square holes.
Preferably, the rectifier shell, the sealing steel gasket and the engine are fixed through a plurality of bolts.
The utility model has the advantages that:
the plane of the engine, on which the rectifier is arranged, is made into the diversion hole and is communicated with the water channel, so that the rectifier shell is directly contacted with cooling water, when the cooling water flows through the rectifier shell, a large amount of heat can be taken away, meanwhile, the heat is dissipated to the air through the rectifier shell, and the two heat dissipation modes are overlapped, so that the heat dissipation effect is doubled, and the normal operation of the rectifier under high current is ensured.
Drawings
The utility model is further described below with reference to the accompanying drawings and examples:
FIG. 1 is a schematic diagram of a prior art outboard engine rectifier heat sink installation;
fig. 2 is a schematic diagram of the heat sink mounting of the outboard engine rectifier of the present utility model.
Detailed Description
As shown in fig. 2, the outboard engine rectifier heat dissipating device of the utility model comprises a rectifier housing 1, an outboard engine 2, and a seal steel gasket 3; the rectifier housing 1 is mounted on the surface of the engine 2; square diversion holes 4 are formed in the surface of the engine at the position where the rectifier shell is arranged, and the diversion holes 4 are communicated with a cooling water channel in the engine, so that cooling water of the engine flows through the surface of the rectifier shell 1. A sealing steel gasket 3 is also arranged between the rectifier shell and the surface of the engine to prevent water leakage. The rectifier shell 1, the sealing steel gasket 3 and the engine 2 are fixed through a plurality of bolts 5.
In the prior art, only the shell is used for radiating heat to the air, so that when the current of the rectifier is large, the heat cannot be fully radiated, and the rectifier is easy to burn out. After improvement, the plane of the rectifier installed on the engine is made into a diversion hole and is communicated with the water channel, so that the rectifier shell is directly contacted with cooling water, a large amount of heat can be taken away when the cooling water flows through the rectifier shell, meanwhile, the heat is dissipated to the air through the rectifier shell, and the two heat dissipation modes are overlapped, so that the heat dissipation effect is greatly improved, and the normal operation of the rectifier in high current is ensured.
The above embodiments are only for illustrating the technical concept and features of the present utility model, and are intended to enable those skilled in the art to understand the content of the present utility model and implement the same according to the content of the present utility model, and are not intended to limit the scope of the present utility model. All modifications made according to the spirit of the main technical proposal of the utility model should be covered in the protection scope of the utility model.
