To prevent freezing of a relay.SOLUTION: A relay freezing prevention device includes: an inlet valve which opens and closes an inlet formed in a relay case provided in a vehicle; an outlet valve which opens and closes an outlet formed in the relay case; a low-temperature gas channel which communicates to the inlet, communicates to the outlet on the downstream side of the inlet, and allows dry gas at a lower temperature than the inside of the relay case to flow therein; a channel opening/closing valve which makes a connection spot of the inlet and a connection spot of the outlet communicate to each other in the low-temperature gas channel or cuts off the connection; an actuator which operates the channel opening/closing valve; and a control device which has one or more processors and one or more memories connected to the processors. When a prescribed condition is satisfied, the processor executes processing of driving the actuator to operate the channel opening/closing valve and cutting off the connection between the connection spot of the inlet and the connection spot of the outlet in the low-temperature gas channel.SELECTED DRAWING: Figure 1
【課題】リレーの氷結を防止する。【解決手段】リレー氷結防止装置は、車両に設けられるリレーケースに形成された入口を開閉する入口弁と、リレーケースに形成された出口を開閉する出口弁と、入口と連通し、入口よりも下流側において出口と連通し、リレーケース内よりも低温の乾燥気体が流れる低温気体流路と、低温気体流路における、入口の連通箇所と出口の連通箇所とを連通させる、または、連通を遮断する流路開閉弁と、流路開閉弁を動作させるアクチュエータと、1つまたは複数のプロセッサ、および、プロセッサに接続される1つまたは複数のメモリを有する制御装置と、を備え、プロセッサは、所定の条件を満たした場合に、アクチュエータを駆動させて流路開閉弁を動作させ、低温気体流路における、入口の連通箇所と出口の連通箇所との連通を遮断することを含む処理を実行する。【選択図】図1
