DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a switch cabinet in general and a switch cabinet employing a cooling device in particular.
BACKGROUND OF THE INVENTION
It is known that a cooling device instead of a wall can be attached to a cabinet body. Such a design of a switch cabinet is known from U.S. Pat. No. 3,559,728. With these types of switch cabinets the cooling device features a tub-shaped housing outer part that is subdivided into two chambers. Each of the chambers receives cooling device components of the cooling circuit. The first chamber makes ambient contact, while the second chamber faces the inner space of the switch cabinet.
A cooling device that is designed as a wall element is known from FR 70 05704. As such, it projects into the inner space and thereby diminishes the volume available for built-in components of the switch cabinet.
OBJECTS OF THE INVENTION
The object of the invention is to provide a switch cabinet that overcomes the shortcomings of the prior art.
Another object of the invention is to provide a switch cabinet having a cooling device capable of being connected to the cabinet body like a cabinet door.
Still another object of the invention is to provide a switch cabinet having a cooling device capable of being connected to the cabinet body as a door having either a left or right hinge. How these and other objects are accomplished will become apparent from the following descriptions and from the drawings.
SUMMARY OF THE INVENTION
The invention involves an improvement to a switch cabinet having a cabinet body that capable of being closed by a cabinet door. Such cooling device includes an inner circuit having a fan and a vaporizer and an outer circuit having a compressor, a condenser and a fan. The cooling device is provided with a tub-shaped outer housing part that connects to, articulates on and closes the cabinet body. Such outer housing is provided with a covering carrier plate such that the space surrounded by the outer housing part and the carrier plate forms an upper and a lower receiving space. The carrier plate features air suction openings in the area of the upper receiving space and an air outlet opening for the lower receiving space.
The improvement involves the cooling device which is designed as a cabinet door, in that the cooling device components of the inner circuit are arranged in the upper receiving space which is open toward the top, fastened to the carrier plate and hermetically covered, while the cooling device components of the outer circuit are arranged in the lower receiving space that is open toward the bottom and connected to the carrier plate. In such an arrangement, fresh air for the outer circuit is drawn through the open lower side of the lower receiving space, over the cooling device components of the outer circuit and into the lower area of the upper receiving space where it is conducted off at the open side of the upper receiving space.
In a preferred embodiment of the invention, the housing outer part practically replaces the cabinet door and, as such, is attached to the cabinet body. In such an embodiment, the carrier plate bears all of the components of the cooling device and is thus capable of being connected to the housing outer part in such a manner so as to allow arrangement of the components of the cooling device independent of the positioning of the cooling device.
As a result of the subdivision of the cooling device into an upper and a lower receiving space and the distribution of the inner and outer circuit components within such spaces, the hermetic covering of the components of the inner circuit creates a definite decoupling of the two circuits thus preventing condensation water from reaching the inside of the cabient body. The design of the cooling device is simple in that the components are all capable of being fastened to the carrier plate.
In one embodiment of the invention, the hermetic covering of the components of the inner circuit is achieved in that the cooling device components of the inner circuit are covered
