Embodiment Construction
[0019] According to a preferred embodiment of the present invention, it is used to connect the cooling device arranged on the top of the cabinet to the top of the switch cabinet, so as to connect the inner space of the switch cabinet with the internal circulation of the coolant circuit of the cooling device arranged on the top of the cabinet. A coupled bottom trough provided with a pipe head 10 for an air outlet, as in Figure 1 to Figure 3 shown in different diagrams. This pipe head 10 fits over the existing pipe socket and can thus be replaced or retrofitted relatively easily.
[0020] figure 1 It shows a perspective view of the pipe head 10 in a basically installed state viewed from the side of the cooling device arranged on the top of the cabinet. In the hollow cylindrical body 12, the outer diameter of which corresponds substantially to the inner diameter of the sleeve to be fitted with the head 10, three ventilation vanes 22, 24, 26 are provided which are hinged on a l...

The invention relates to a bottom tank (100) for connecting a cooling device arranged on the top of the cabinet with the top of the switch cabinet so as to couple the inner space of the switch cabinet with the internal circulation of the coolant circuit of the cooling device arranged on the top of the cabinet , the bottom tank (100) has at least one air inlet hole (106) aligned with the hot air outlet of the inner space of the switch cabinet and at least one air outlet hole communicated with the cold air inlet of the inner space of the switch cabinet, wherein the air inlet Holes and air outlets are provided in the bottom (102) of the bottom tank (100), which is characterized in that a plurality of outlets The air holes are arranged around the at least one air inlet hole (106), and at least a part of the air outlet holes are pivotable about an axis extending in the plane of the bottom (102) and about a plane perpendicular to the bottom (102) Extended axis-rotating ventilation vanes (22, 24, 26) cover.
Description
technical field [0001] The invention relates to a bottom tank that connects the cooling device arranged on the top of the cabinet with the top of the switch cabinet so as to couple the inner space of the switch cabinet with the internal circulation of the coolant circuit of the cooling device arranged on the top of the cabinet. The slot has at least one air inlet hole aligned with the hot air outlet of the inner space of the switch cabinet and at least one air outlet hole communicated with the cold air inlet of the inner space of the switch cabinet, wherein the air inlet hole and the air outlet hole are arranged at the bottom of the tank In the bottom and covered by ventilation grilles or ventilation vanes. Background technique [0002] Such a bottom trough is known from DE 10 205 646 A1. It has been found that the base channel provides a simple and variable air conduction between the switch cabinet and the cooling device and in this case simultaneously simplifies and bring...
