The invention relates to a liquefied natural gas storage tank capable of preventing liquid from writhing and generating overpressure. Heat pipes installed in the vertical direction are arranged in the liquefied natural gas storage tank. The lower ends of the heat pipes are connected with the tank bottom of the liquefied natural gas storage tank. The upper ends of the heat pipes are higher than the liquefied natural gas liquid level in the liquefied natural gas storage tank. The liquefied natural gas storage tank has the beneficial effects that heat is transmitted through the finned heat pipes with high heat conductivity, the temperature of bottom liquid and upper liquid in the liquefied natural gas storage tank is balanced, the situation that the bottom liquid of the storage tank is excessively saturated can be effectively avoided, and a writhing phenomenon of the storage tank is avoided. 本发明涉及种防止液体翻腾超压的液化天然气储罐，在液化天然气储罐中设有沿垂直方向安装的热管，所述热管的下端与液化天然气储罐的罐底连接，所述热管的上端高出液化天然气储罐内的液化天然气液面；本发明的有益效果是：采用带有翅片的高导热性能的热管传递热量，
