Mechanism for preventing reflow for fan flap failure

A modular fan assembly to prevent reflow, the assembly comprising:

• a socket defined by a first side wall, a second side wall, and a horizontal shelf, the socket receives a fan module;
• a swinging fan flap rotatably coupled to the first side wall, the swinging fan flap moving in a curved path relative to the first side wall;
• and
• an anti-reflow device coupled to the second side wall of the socket, the anti-reflow device having a proximal end and a distal end, the anti-reflow device further including:
• an attachment feature disposed at the proximal end, the attachment feature attaching the proximal end to the second side wall of the socket;
• an embossed feature disposed between the proximal end and the distal end, the embossed feature contacting the fan module in response to the fan module being inserted into the socket;
• and
• a stopping feature disposed at the distal end, the stopping feature contacting the swinging fan flap in response to the swinging fan flap moving toward the stopping feature.
