The present invention relates to a greenhouse heat dissipation structure, comprising a base, a top frame, a hoisting cloth, and an extension frame, the pedestal has a chamber, and a cover is arranged around the chamber； and the top frame is disposed above the pedestal. The upper side has an inclined top plate, and the top side of the top frame has a vertical surface corresponding to the vertical direction of the ground, and the façade is provided with a ventilation opening； and the hoisting cover is disposed at the opening position, and can cover or not cover the opening； The extension is arranged at a position in front of the opening of the façade, and has a bottom frame extending forward from the bottom of the opening. The curved front frame is disposed at a position from the front end of the chassis to the opening of the façade, and the front frame is disposed larger than the opening area of the façade. Insect net body； this design can have better heat dissipation efficiency.本創作係一種溫室散熱構造，包括一基座、一頂架、一捲揚遮布、一延伸架，該基座具容室，容室周圍設置遮體；又該頂架設於基座上方，上方具斜向頂板，該頂架側高端向下對應地面垂直方向具立面，該立面設置通風開口；又該捲揚遮布設於開口位置，並可遮覆或不遮覆開口；又該延伸架設於立面之開口前方位置，具一由開口下方向前延伸之底架，該底架前端至立面之開口上方位置設置弧形前架，又於前架設置大於立面開口面積之防蟲網體；藉此本創作可具較佳散熱效率。
