Support structure of heat dissipation unit

The utility model relates to a support structure of a heat dissipation unit, which is suitable for being used in the heat dissipation unit, two sides of the heat dissipation unit respectively form a condensation side and an evaporation side which are respectively abutted against two ends of the support structure, the support structure comprises a carrier part and a spine-shaped part, the carrier part is provided with a contact surface and a bearing surface, and the contact surface is provided with a plurality of heat dissipation holes. The spine-shaped part is formed by arranging a plurality of needle columns on the bearing face of the carrier part in an array mode, gaps are formed among the needle columns to form a channel, and by means of the supporting structure provided with the spine-shaped part, the circulation flow rate of vapor and liquid in the heat dissipation unit can be accelerated, and the heat dissipation efficiency is greatly improved. 本实用新型涉及一种散热单元的支撑结构，是适用于一散热单元内，该散热单元的两侧分别形成一冷凝侧及一蒸发侧是分别与该支撑结
