An outdoor display screen heat dissipation and waterproof enclosure, comprising an enclosure frame, a sheet metal enclosure shell, and a mounting frame for mounting and fixing a display module, wherein the front side of the sheet metal enclosure shell has a display screen window, and the mounting frame is located within the display screen window, characterized in that: The mounting frame consists of several vertical profiles fixed to the housing frame, several display module bases overlapping the vertical profiles, pressure rods, and a water tank. Each vertical profile includes a first back plate and two first side plates, with an obtuse angle between the first side plates and the first back plate. Each display module base includes a second back plate and two second side plates. A waterproof flange extends from the upper end of the display module base; the waterproof flange has an inward-sloping structure and forms a limiting step at the connection point with the second back plate and the second side plates. The pressure rod includes a third back plate and two third side plates. The two second side plates of the display module base overlap the front sides of the two adjacent first side plates on the two adjacent longitudinal profiles. A connector is fixedly connected between the third back plate on the pressure rod and the first back plate, so that the second side plate is firmly clamped between the first side plate and the third side plate. The two adjacent display module bases abut against each other at the limiting step. The water tank is installed horizontally at the bottom of all longitudinal profiles. The bottom of the water tank is connected to a drain pipe that penetrates the sheet metal shell. The back of the mounting frame has a plurality of longitudinal air guide slots defined by the longitudinal profiles and the display module bases.

2. The outdoor display screen heat dissipation and waterproof enclosure according to claim 1, characterized in that: The second back plate has a weight reduction opening in the middle and several screw mounting holes surrounding the weight reduction opening. A sealing gasket is also attached to the second back plate, and the weight reduction opening and the screw mounting holes are both located within the area surrounded by the sealing gasket.

3. The outdoor display screen heat dissipation and waterproof enclosure according to claim 1, characterized in that: The connector consists of an outer limiting cap, a connecting rod, and an inner limiting cap. The outer limiting cap is pressed against the third back plate, and the inner limiting cap is pressed against the first back plate. The connecting rod passes through the first back plate and the third back plate in sequence and is fixedly connected to the two limiting caps.

4. The outdoor display screen heat dissipation and waterproof enclosure according to claim 1, characterized in that: The sheet metal box shell is also provided with a vertical partition plate relative to the box frame. The partition plate divides the inner cavity of the sheet metal box shell into a front half and a rear half, and the upper and lower sides of the two halves are connected.

5. The outdoor display screen heat dissipation and waterproof enclosure according to claim 4, characterized in that: The bottom of the box frame is also fixedly connected to a support column.
