Abstract
The utility model belongs to the technical field of an engine for the generator, specifically be a built-in journey ware that increases of rectifier bridge, including engine, generator and rectifier bridge, the rectifier bridge is located the inside of increasing journey ware casing, the rectifier bridge is connected with the radiator, increase inside being provided with of journey ware casing and carrying out radiating wind channel to the radiator. The problem of rectifier bridge when built-in among the prior art takes place the high temperature easily and damage is solved to this scheme.
Description
Technical Field
The utility model belongs to the technical field of an engine for the generator, specifically be a built-in journey ware that increases of rectifier bridge.
Background
At present, when the battery electric quantity of the range-extended electric low-speed four-wheel vehicle is sufficient, the power battery drives the motor to provide the driving power requirement of the whole vehicle, and at the moment, the range extender does not participate in the work. When the electric quantity of the battery is consumed to a certain degree, the range extender is started, and the range extender provides energy for the battery to charge the power battery. When the electric quantity of the battery is sufficient, the range extender stops working again, and the battery drives the motor to drive the whole vehicle. And in current increase journey ware, its rectifier bridge is installed inside the controller casing, when heavy current passes through, makes rectifier bridge bulk temperature rise fast easily, and then leads to the load too big, can burn out the rectifier bridge even when serious.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a built-in journey ware that increases of rectifier bridge to the problem of the too high and damage of easy emergence temperature when rectifier bridge is built-in among the solution prior art.
In order to achieve the above object, the utility model discloses a basic scheme provides a built-in journey ware that increases of rectifier bridge, including engine, generator and rectifier bridge, the rectifier bridge is located the inside of increasing journey ware casing, the rectifier bridge is connected with the radiator, increase inside being provided with of journey ware casing and carrying out radiating wind channel to the radiator.
The principle and the beneficial effect of the basic scheme are as follows: through the setting of radiator and wind channel, make rectifier bridge and radiator carry out the heat exchange, the radiator realizes the heat dissipation through the wind channel to make rectifier bridge realize the heat dissipation through the radiator, effectively avoided rectifier bridge to damage because of the high temperature, thereby guaranteed rectifier bridge's job stabilization nature.
Furthermore, the air duct is at least partially positioned in the generator shell, and a fan is statically connected to a rotor assembly of the generator. By adopting the arrangement, the air flow generated by the fan inside the generator housing can be conveniently utilized to enter the air channel, so that the radiator is cooled, an air source of the air channel is not required to be independently arranged, and the structure is favorably simplified.
Further, the rectifier bridge and the radiator are both located inside the generator housing. By adopting the arrangement, the rectifier bridge and the radiator are convenient to be closer to the fan of the generator, so that the arrangement of the air channel is facilitated to be simplified, and the quick heat dissipation is convenient to realize.
Furthermore, an air duct air outlet opposite to the radiator is formed in the generator shell. By adopting the arrangement, the heat in the generator shell can be timely discharged through the air outlet of the air duct, and the quick heat dissipation is favorably realized.
The beneficial effect of this scheme lies in: the rectifier bridge has the advantages that timely heat dissipation is achieved when the rectifier bridge is built in, and the problem that the rectifier bridge is damaged due to overhigh temperature is solved, so that the running stability of the rectifier bridge is improved, and the working reliability of the range extender is guaranteed.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of a built-in range extender of a rectifier bridge of the present invention;
FIG. 2 is a right side view of FIG. 1;
fig. 3 is a sectional view a-a in fig. 1.
Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the generator comprises an engine 1, a crankcase 11, a generator shell 2, an air duct air outlet 21, an air duct air inlet 22, a radiator 3, a rectifier bridge 4 and a fan 5.
The embodiment is substantially as shown in figures 1, 2 and 3 of the accompanying drawings: a built-in range extender of a rectifier bridge comprises an engine 1, a generator and a rectifier bridge 4, wherein the engine 1 comprises a crankcase 11, and a crankshaft is arranged in the crankcase 11; the generator comprises a stator assembly and a rotor assembly connected with a crankshaft, a fan 5 is fixedly connected to the rotor assembly through bolts, a generator shell 2 covering the rotor assembly is arranged on the outer side of the rotor assembly, and the generator shell 2 is fixedly connected with a crankcase 11. The rectifier bridge 4 is installed inside the generator housing 2 through bolts and located at one side of the rotor assembly, and the bottom of the rectifier bridge 4 is connected with the radiator 3. An air duct air outlet 21 opposite to the radiator 3 is formed in the generator housing 2, an air duct air inlet 22 is formed in the generator housing 2, and the radiator 3 is located on an air duct formed in the generator housing 2.
The specific implementation process is as follows: increase journey ware during operation, the bent axle drives the rotor subassembly rotation of generator, thereby make fan 5 rotate, make generator housing 2 breathe in through wind channel air intake 22 when fan 5 rotates, and make the air current discharge from wind channel air outlet 21 behind radiator 3, thereby make the air current take away the heat of radiator 3, and then make radiator 3 can be timely carry out the heat exchange with rectifier bridge 4, make the heat dissipation that rectifier bridge 4 can be timely, the problem of rectifier bridge 4 damage because of the high temperature has been avoided taking place.
The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the present invention is defined by the claims, and the description of the embodiments and the like in the specification may be used to interpret the claims.
