The first and second openings are formed in the wall portion. The circuit portion includes first and second circuit elements those fixed within the housing. The regulation wall portion provide a first air passage in communication with the first opening, a second air passage in communication with the second opening, and a bent air passage allowing the first air passage and the second air passage to communicate with each other. The fan is configured to generate an air-flow flowing between the first air passage and the second air passage. The fan is positioned to face the first opening. The first circuit element is positioned in the first air passage. The second circuit element is positioned in the second air passage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"DC power supply device","description":"A DC power supply device includes a housing including a wall portion, a first opening and a second opening, a circuit portion, a regulation wall portion, and a fan.
