The paper describes usage of nitrogen-filled heat pipes for pre-cooling of the superconducting wiggler with "dry" cryostat (ANKA/CLIC Superconducting multipole wiggler 2015). In our design the first stages of cryo-coolers are connected to the magnet yoke by two heat pipes, which provide high heat transmission rate (up to 100 W per tube) in the temperature range from 300K down to 70K. When the nitrogen reaches its freezing point, an automatic thermal contact gap occurs. The heat pipes allowed us to exclude usage of liquid nitrogen from the process of pre-cooling of the magnet.
