The present invention relates to a greenhouse heat dissipation structure, comprising a greenhouse main body and at least one baffle having a top plate corresponding to the ground oblique direction, the top plate having a high and a low end, and corresponding to the high-end downward vertical direction at least one height of the ground surface The heat dissipation opening further comprises a cover covering the position around the main body of the greenhouse； and the bottom of the baffle is engaged with the bottom of the opening of the greenhouse body, the top and the opening are spaced apart from each other, and the baffle and the opening are extended from the bottom to the top. The angle between the two； this creation can have better heat dissipation.本創作係一種溫室散熱結構，包括一溫室主體、至少一擋板，該溫室主體具一對應地面斜向之頂板，該頂板具高、低端，對應高端向下垂直方向設置至少具地面一段高度之散熱開口，又包括遮體包覆溫室主體周圍位置；又該擋板底部與溫室主體之開口下方接合，頂部與開口具展開間隔，並使擋板與開口間具由下而上向外展開之夾角；藉此本創作可具較佳散熱功效。
