Description

Electronic Control Unit The present invention relates to an electronic control device, and more specifically, to an electronic control device with improved water resistance. With the advancement of electronic control technology for automobiles, many mechanical components used for vehicle control are being replaced by electronic control units (ECUs). As the number of components controlled by ECUs increases, the heat generated by these units is also increasing. To enhance heat dissipation, fans are applied, which connects the exterior and interior of the ECU; however, this leads to a problem where the ECU's water resistance performance is reduced. Accordingly, there is a growing need for electronic control units that can increase heat dissipation while improving water resistance. The background technology of the present invention is disclosed in Korean Registered Patent Publication No. 10-1610892 (Registered on April 4, 2016; Title of Invention: Electronic control device for a vehicle using a potting layer and method for manufacturing the same). FIG. 1 is a perspective view of an electronic control device according to one embodiment of the present invention, viewed from a first point in time. FIG. 2 is an exploded perspective view of an electronic control device according to one embodiment of the present invention, viewed from a first point in time. FIG. 3 is a perspective view of an electronic control device according to one embodiment of the present invention, viewed from a second viewpoint. FIG. 4 is an exploded perspective view of an electronic control device according to one embodiment of the present invention, viewed from a second viewpoint. FIG. 5 is a perspective view of the panel portion of the first embodiment of the present invention. FIG. 6 is a perspective view of the panel portion of the second embodiment of the present invention. FIG. 7 is a perspective view of the panel portion of the third embodiment of the present invention. FIG. 8 illustrates a cross-section of a panel portion according to a third embodiment of the present invention. FIG. 9 is an enlarged view of a cross-section of a panel portion according to a third embodiment of the present invention. Hereinafter, an electronic control device according to the present invention will be described with reference to the attached drawings. In this process, the thickness of lines or the size of components shown in the drawings may be exaggerated for clarity and convenience of explanation. Furthermore, the terms described below are defined considering their functions in the present invention, and these may vary depending on the intention or convention of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification. FIG. 1 is a perspective view of an electronic control device according to an embodiment of the present invention viewed from a first viewpoint, FIG. 2 is an exploded perspective view of an electronic control device according to an embodiment of the present invention viewed from a first viewpoint, FIG. 3 is a perspective view of an electronic control device according to an embodiment of the present invention viewed from a second viewpoint, and FIG. 4 is an exploded perspective view of an electronic control device according to an embodiment of the present invention viewed from a second viewpoint. With reference to FIGS. 1 to 4, the electronic control unit (1) will be described in detail. The electronic control unit (1) may include a base part (10), a panel part (20), a heat dissipation part (30), a cover part (40), a heat dissipation fan (50), and a control part (60). The base part (10), the panel part (20), the heat dissipation part (30) and/or the cover part (40) may form the exterior of the electronic control unit (1). The base portion (10) can be composed of a lower surface (e.g., -Z-axis direction), a side surface (e.g., Y-axis direction), a front surface (e.g., -X-axis direction), and a rear surface (e.g., +X-axis direction). A hole is formed in the panel section (20) so that the outer side (e.g., -X-axis direction) and the inner side (e.g., +X-axis direction) of the panel section (20) can be connected. The hole can be placed at various locations on the panel section (20). Accordingly, air from the outer side of the panel section (20) can pass through the panel section (20) and move to the inner side of the panel section (20). The panel section (20) can be placed on the front side (e.g., -X-axis direction) of the base section (10), and the panel section (20) can be combined with the base section (10) and combined with the heat dissipation section (30).
