For the heat dissipation, the heat dissipation window is directly seted up at cabinet chamber side to the tradition mode to expect to solve the heat dissipation problem through the air convection, but often the effect is unsatisfactory among the actual operation, enters into its reason and lies in: on one hand, in a windy environment, the ideal state is that wind power enters and is distributed in the cabinet cavity through the heat dissipation window on one side and is taken out of the heat dissipation window on the other side along with airflow; however, because the electrical components in the cabinet cavity have electrical connection problems, an extra shielding partition plate, i.e., an isolation steel plate, is often required to be arranged to achieve the electrical isolation effect of the two groups of electrical components; the existence of monoblock isolation steel sheet can reduce the air current velocity of flow in the cabinet intracavity, directly cuts off the circulating route of air current even, is obviously unfavorable for the formation in air convection flow field, very big influence actual radiating effect. On the other hand, under the windless environment, the outside does not have wind-force to influence cabinet intracavity air current, and the steam in the cabinet intracavity can rise to cabinet chamber top naturally and assemble, and can not directly discharge rapidly via the heat dissipation window of one side to lead to the heat at cabinet chamber top to gather the phenomenon, also do not contribute to actual heat dissipation. Therefore, a solution is needed.
