The electric control cabinet according to claim 1, characterized in that the heat dissipation end comprises: Multiple heat dissipation fins are fixed from top to bottom, and multiple heat dissipation fins are arranged at intervals in the horizontal direction. The wind from the first air inlet flows through the gaps between the heat dissipation fins under the action of the air guide plate and then flows out from the first air outlet above to take away the heat from the heat dissipation fins. 3. The electric control cabinet according to claim 1, characterized in that the air guide plate comprises: The air collecting plate extends upward from the upper end of the air guide plate parallel to the heat dissipation fins to the upper end of the heat dissipation fins. 4. The electric control cabinet according to claim 3, characterized in that the air guide plate further comprises: The support plate connects the air collecting plate and the side plate of the box and is used to fix the support plate. 5. The electric control cabinet according to claim 3, characterized in that the air guide plate further comprises: The air exhaust plate is arranged above the air collecting plate and is inclined in an upward direction along the upper end of the air collecting plate toward a direction away from the heat dissipation fins. 6. The electric control cabinet according to claim 1, characterized in that: The upper end of the partition is connected to the top plate of the box body, and the two side ends of the partition are bent horizontally toward the heat dissipation fins to form a bent edge of the vertical partition. The end of the bent edge is fixedly connected to the side plate of the box body, so that the partition and the side plate of the box body enclose the heat dissipation end to form an independent air duct. 7. The electric control cabinet according to any one of claims 1 to 6, further comprising: A second air inlet, corresponding to the first subspace, is disposed at the bottom of one side plate of the box body; The third air inlet corresponds to the second subspace and is arranged at the bottom of the other side plate of the box body opposite to the second air inlet. 8. The electric control cabinet according to any one of claims 1 to 6, further comprising: The second air outlet is arranged at the top of the side plate of the box body corresponding to the first subspace. 9. The electric control cabinet according to any one of claims 1 to 6, further comprising: The fan is arranged on the top wall of the box body corresponding to the second subspace and corresponding to the first air outlet, and is used for guiding the hot air in the second subspace to the first air outlet for discharge. 10. An air conditioner, comprising: An electric control cabinet as claimed in any one of claims 1 to 9.
