Electronic control apparatus for vehicle using radiation board and manufacturing method thereof
Disclosed are an electronic control apparatus for a vehicle and provides an electronic control apparatus for a vehicle using a radiation board in which a radiation plate having a slide fixing structure (for example, “U” shaped) is attached onto a portion opposite to a portion which requires the radiation in a printed circuit board (PCB) and if additional radiation performance is required, a slidable radiation board which is detachable is attached/detached to directly emit heat to the atmosphere through the radiation plate and the radiation board to the atmosphere, thereby improving a radiation effect and to implement a standard platform of the radiation structure and implement an optimal radiation structure through a slidable radiation board and a manufacturing method thereof.
1. An electronic control apparatus for a vehicle, comprising:
a printed circuit board (PCB) which includes an electronic control substrate which electrically controls multiple parts of a vehicle and electronic components installed on one surface of the electronic control substrate;
a radiation plate which is attached onto another surface which is opposite to the one surface on which the electronic components is located among the other surfaces of the electronic control substrate in order to radiate heat of the electronic components and has a slide fixing structure;
a radiation board which has at least one radiation pin formed on one surface thereof and is slidably attached/detached onto/from the slide fixing structure of the radiation plate;
a connector which includes a connector pin and is coupled to the PCB; and
an overmold housing which overmolds the PCB onto which the radiation plate is attached using a mold resin and overmolds the remaining portion other than another surface onto which the radiation plate is attached among the other surfaces of the electronic control substrate.
2. The electronic control apparatus for a vehicle of claim 1 , wherein the radiation plate has an outer corner having a “U” shaped slide fixing structure so as to slidably fit the radiation board therein.
3. The electronic control apparatus for a vehicle of claim 1 , wherein when an additional radiation structure is required other than the radiation using the radiation plate, the radiation board has various types of radiation pins according to the additional radiation structure.
4. The electronic control apparatus for a vehicle of claim 1 , wherein the radiation board includes at least one radiation pin having an interval between radiation pins or the number of radiation pins according to the additional radiation structure on another surface which is opposite to the one surface on which the electronic components is located, among the other surfaces of the electronic control substrate.
5. The electronic control apparatus for a vehicle of claim 1 , wherein the overmold housing overmolds a portion other than the radiation plate among the other surfaces of the PCB and encloses an outer corner of the radiation plate except for the slide fixing structure of the radiation plate.
6. The electronic control apparatus for a vehicle of claim 1 , wherein the radiation plate is a metal material or a pad type plate.
7. The electronic control apparatus for a vehicle of claim 1 , wherein the overmold housing is injection-molded while being maintained at below predetermined failure threshold temperature and pressure of the electronic control substrate or the electronic components.
8. A manufacturing method of an electronic control apparatus, comprising:
coupling a printed circuit board (PCB) which includes an electronic control substrate which electrically controls multiple parts of a vehicle and electronic components installed on a surface of the electronic control substrate with a connector which includes a connector pin;
attaching a radiation plate having a slide fixing structure onto another surface which is opposite to the one surface on which the electronic components is located among the other surfaces of the electronic control substrate;
overmolding by inserting the PCB onto which the radiation plate is attached in upper and lower molds in which the remaining portion other than another surface on which the radiation plate is attached, is overmolded among the other surfaces of the electronic control substrate and injecting the mold resin therein; and
attaching and/or detaching slidably the radiation board which has at least one radiation pin formed on one surface thereof onto and/or from the slide fixing structure of the radiation plate.
