Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the benefit under 35 U.S. C. § 119(a) of priority to Korean Patent Application No. 10-2024-0154344 filed on Nov. 4, 2024, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes. BACKGROUND 1. Technical Field Exemplary embodiments of the present disclosure relate to an electronic control device, and more particularly, to an electronic control device having improved water resistance. 2. Related Art As electronic control technology for automobiles develops, many mechanical components for controlling automobiles are being replaced by electronic control devices. As the components controlled by electronic control devices increase, the heat generated by electronic control devices is increasing. As a fan is applied to increase the heat dissipation of the electronic control device, the exterior and interior of the electronic control device communicate with each other, which causes a problem in that the water resistance of the electronic control device is reduced. Accordingly, there is an increasing need for an electronic control device capable of improving water resistance while increasing the amount of heat dissipation of the electronic control device. The background technology of the present disclosure is disclosed in Korean Patent Registration No. 10-1610892 (registered on Apr. 4, 2016, entitled “ELECTRONIC CONTROL DEVICE OF VEHICLE USING POTTING LAYER AND MANUFACTURING METHOD THEREOF”). SUMMARY Various embodiments of the present disclosure are directed to an electronic control device having improved water resistance. An electronic control device according to the present disclosure includes a base part including a base plate, a panel part including a panel body disposed on a front of the base part, a panel protrusion protruding outward from the panel body, and a panel ventilation unit including openings in the panel protrusion part, and a heat dissipation part including a heat dissipation body disposed on the base part to face the base plate. The electronic control device may further include a heat dissipation fan disposed on an inside of the panel body to move air from outside of the panel part to inside of the panel part through the panel ventilation part. The panel ventilation unit may include panel lower openings that open toward a lower side of the panel body. The panel part may include panel lower ribs disposed to connect the panel body and the panel protrusion and crossing the panel lower openings. The panel ventilation unit may include panel side openings that open a side of the panel protrusion. The panel ventilation unit may include panel front openings disposed in a direction in which the panel protrusion protrudes. The panel ventilation unit may include panel front ribs that surround the panel front openings and protrude in a direction in which the panel protrusion protrudes. The base part may include a side plate including a first side plate and a second side plate that extend from the base plate and are disposed on respective sides of the base plate, a rear plate that extends from the base plate and is disposed to face the panel body, and a front plate that extends from the base plate and is disposed between the rear plate and the panel body. The electronic control device may further include a control part that is disposed between the base part and the heat dissipation part to generate heat. The heat dissipation part may include a heat dissipation body disposed to face the base plate, and a heat dissipation fin unit that is disposed on an outside of the heat dissipation body to dissipate heat, and the electronic control device may further include a cover part disposed to cover the heat dissipation fin unit. A width of the panel protrusion may be set to 40 mm to 80 mm, a protrusion length of the panel protrusion protruding from the panel body may be set to 20 mm to 40 mm, the height of the panel body is set to 40 mm to 100 mm, and the width of the panel body may be set to 120 mm to 250 mm. The panel protrusion may be disposed between one end and the other end of the panel body. The panel protrusion may include: a panel protrusion body protruding from the panel body to the outside of the panel body; a panel inflow slope disposed on the lower side of the panel protrusion body and connected to the panel ventilation unit, and extending toward the panel body; a panel inflow connection extending from the panel inflow slope; and a panel inflow guide extending from the panel inflow connection and connected to the panel body.
