Description

Technical Field

[0001] The utility model relates to the technical field of fuel cells, and more specifically to a hydrogen fuel cell control device for heavy trucks. Background Art

[0002] At present, hydrogen fuel cells used in heavy trucks need to use a control system to control the supply. As the core component of the power source, the hydrogen fuel cell system has a distributed structure and a harsh electromagnetic environment. The hydrogen fuel cell will cause the temperature of the controller to rise rapidly when working. The controller cannot be evenly dissipated during use, and it is easy to be damaged due to excessive temperature. For example, the application number is: 202221397935.4, an integrated controller for rapid heat dissipation of a fuel cell system, including a main body, a heat dissipation mechanism and an acceleration mechanism. The heat dissipation mechanism is located at the left end of the upper end of the main body, and the acceleration mechanism is located at the right end of the upper end of the main body. The main body includes The patent discloses a controller body, a heat conducting plate, a heat conducting plate and heat dissipation fins. The heat conducting plate is fixedly mounted on the upper end of the controller body. The heat dissipation mechanism includes a baffle, an electric push rod 1, a sliding block, a linear guide rail, a push rod slot, an electric push rod 2, a placement plate and a heat dissipation fan. The baffle is fixedly mounted on the left end of the upper end of the heat conducting plate. The patent dissipates heat from the controller through heat dissipation fins, and uses semiconductor chips to assist in cooling and dissipating wind. The cooling wind is blown to the heat dissipation fins by the guide fan. The semiconductor chips themselves need to dissipate heat, and the temperature is too high to work for a long time. At the same time, the movement mode of the heat dissipation fan conflicts with the effect of the guide fan, and the cooled wind is blown away by the heat dissipation fan, resulting in poor heat dissipation effect.

[0003] In response to the above-mentioned problem, regarding the technical problem that the movement mode of the heat dissipation fan conflicts with the effect of the guide fan, and the cooled air is blown away by the heat dissipation fan, resulting in poor heat dissipation effect, after a lot of searching, a Chinese utility model with application number CN219303715U was found, which provides a controller for a hydrogen fuel cell system. The utility model includes a controller body, a heat conduction plate and a mounting seat; the utility model cools the air in the mounting seat through a semiconductor refrigeration sheet, which is blown to the heat dissipation fins by the heat dissipation fan, and the air flow at the heat dissipation fins is increased. It has a reasonable structure and good heat dissipation effect, and the semiconductor refrigeration sheet is cooled by the fan to ensure its normal operation. However, the technical solution provided by the patent has the following problems: the semiconductor refrigeration sheet is placed behind the heat dissipation fan, the air in the mounting seat is cooled by the semiconductor refrigeration sheet, and the cooled air is blown to the heat dissipation fins by the heat dissipation fan. It is difficult to effectively blow the cold air behind the heat dissipation fan forward, and the setting effect of the semiconductor refrigeration sheet is relatively weak.
