New description: [New technical field] This creation is about a kind of heat dissipation improvement structure for vehicle mine, /5 4*, ^心## (4), especially refers to a circuit board inside the power converter. The sound #^ is placed on the part with a heat sink and a wind fan, which is effective for quickly dissipating heat from electronic parts. Early use of power converter heat change [previous technology] β General consumers in the car want to use the electric port mouth & electrical port (such as: car vacuum cleaner, machine, etc.), must be through the car The traitor cup 4 is used in the car. If you want to use the electronic products used in the sputum (such as · signing) (such as "type computers, etc.", you can not use it in the car, because of the electronic products used in the home. The plug is not a special plug for dry use, and the two are plugs of different specifications. For the consumer, it can only say that the sound is helpless. Some of the manufacturers have developed a power converter that can convert the spleen into a large one. Although it can achieve the purpose of power plug conversion / month buyers can also use the home electronic products in the car, but its body is large, placed, single, quite occupying space, and the space available on the car is not a reclamation , 婪甘— 夕 ☆ its body is too large' is also a headache for consumers. In view of this, this is not only to improve the above various shortcomings, it has developed a kind of convertible power supply and its light weight Small and other effects. It can be seen that there are still many shortcomings in the above-mentioned conventional power converters, which are not the designers of a good cover, and need to be improved. The creator of this case is derived from the above-mentioned conventional belts, and the power converters on the shop wires. All the shortcomings were improved and innovated by Sui Si, and after years of hard work and painstaking research, I finally succeeded in researching M323794 to complete the heat-dissipation improvement structure of this vehicle power converter. [New content] The purpose of this creation That is, a heat sink and a fan are disposed on the electronic component of the circuit board in the power converter, and when the cold air is sucked into the power converter, the heat energy of the heat sink can be taken away by the heat sink. The generated hot air will be discharged from the power converter by the fan, so that the heat can be quickly dissipated for the electronic parts, and the structure of the power converter can be used to improve the structure. _ This creation is based on the provision of light weight A heat-dissipating structure of a small, heat-dissipating and low-cost vehicle power converter. Another object of the present invention is to provide a heat dissipation using the present invention. The heat-efficiency improvement structure of the vehicle power converter that reduces the service life of the power converter, such as shortening or failure, etc. The heat-dissipation improvement structure of the vehicle power converter capable of achieving the above-mentioned new purpose includes: a power converter, a circuit board, a fan, a heat sink; wherein the power converter has an air inlet at a side of the power converter, and is disposed on the upper casing of the power converter, and the air outlet is switched A circuit board is disposed in the device, and a fan is coupled to the circuit board, and a heat sink is disposed on the fan; and the heat dissipation improvement structure of the power converter for the vehicle is formed by the components of the above components. The heat sink and the fan can be used to draw cold air into the power converter from the air inlet. 'Because the electronic components on the board will generate high temperature, the heat sink will help dissipate the electronic components of the board. The cold air will increase the function of the heat sink to dissipate heat quickly, and the hot air will be discharged through the exhaust port by the fan, thereby effectively reducing the power consumption of the M323794. Case of life improved heat dissipation structure of a converter failure or shortened. [Embodiment] Please refer to FIG. 1 and FIG. 2, the heat dissipation improvement structure of the power converter for a vehicle provided by the present invention mainly includes: a power converter 1 provided with a circuit board U And a fan 12 is disposed on the circuit board u, and an air inlet I3 is opened at the side of the power converter 1 for the cold air to enter through the port; a heat sink 2, the heat sink 2 is set At the upper end of the circuit board U fan 12, the heat sink 2 is made of a metal plate with good thermal conductivity and is directly punched with at least one or more heat dissipation fins 21 from the base material; the heat dissipation fins 21 and the base material For the integral molding system, the heat on the heat sink 2 can be accelerated to the outside through the heat dissipation fins 21; the heat sink 2 can be made according to the size of the heat dissipation area to form the heat sink 2 which can meet the size of the heat dissipation area; I»-upper case The upper housing 3 is disposed on the upper side of the power converter i, and the upper housing 3 defines an air outlet 31, and the air outlet 31 is disposed corresponding to the fan 12 of the power converter 1; Next housing 4, the lower housing 4 is arranged The lower side of the power converter is provided on the upper and lower sides of the power converter 1 by the above-mentioned upper and lower casings 3, 4, so that the power supply conversion 1 is completely subjected to the shooting, and the 艮p 游士,士μ 兀王和均Closed, that is, the heat-dissipating improved structure of the power converter for the vehicle forming the same; with the heat sink 2 and the implementation of the fan 12, the heat sink 2 can help the electronic components of the circuit board 11 to quickly dissipate heat, thereby effectively reducing the power source of the vehicle M323794. The heat dissipation of the converter improves the life of the structure or the failure. Referring to FIG. 3A and FIG.B, FIG. 3 is a schematic view showing the implementation of the heat-dissipation improving structure of the power converter for the vehicle. As can be seen from the figure, when the power converter 1 starts to operate, the fan 12 in the synchronous state is activated, due to The electronic components on the circuit board u in the power converter 1 will generate high temperature. At this time, the heat sink 2 on the circuit board n will effectively dissipate heat, and when the fan 1 is started, the cold air can be taken in. The air port-13 is sucked, and the cold air passes through the heat sink 2 to take away the heat energy of the heat sink 2, and then the hot air generated by the heat energy is discharged to the outside of the power converter 1 through the air outlet 31 through the fan 12, thereby being effective. Achieve rapid heat dissipation.
