Abstract: A thermal management system for an enclosure containing electrical components includes a cooling unit for controlling temperature inside the enclosure and a controller for the cooling unit, the controller being configured so that it can receive a three-phase power input signal and distribute power and control connected components using the three-phase signal. The controller can protect the compressor in critical scenarios such as thermal overload and overcurrent. The controller can output various faults such as missing phase alarm, imbalance phase alarm, overcurrent alarm, thermal overload alarm, door open alarm, and temperature and pressure alarms. An auto phase sequence correction controls the phase relay, accepting 3 phase 480 VAC power input from facility power terminal, supplying 3 phase power to the compressor and motor impellers, 12V DC power to a display unit, and 24V DC power to a remote access control module.

Abstract: An interlock for an enclosure can include a primary door activator with an activator arm, a secondary door activator, and a rotatable arrangement that links the primary and secondary door activators. The activator arm can block a primary door of the enclosure from being closed when the activator arm is in an open configuration. The activator arm can be configured to rotate with the rotatable arrangement in a first direction towards the open configuration as the primary door is opened, and in a second direction away from the open configuration as the primary door is closed. The secondary door activator can be configured to engage the rotatable arrangement to prevent rotation of the rotatable arrangement when the secondary door is open, and to permit rotation of the rotatable arrangement when the secondary door is closed.

Abstract: A filter housing can support filter media for a fan arrangement. The filter housing can include a filter body with a first opening at a first end and a second opening at a second end. A bell portion can be disposed between the air inlet opening and the air outlet opening and can define a cavity within the housing body. An air-permeable filter support can extend into the cavity to support the filter media within the cavity, with the filter media spaced apart from at least one of the first and second openings.

Abstract: Embodiments of the invention provide a system and a method for mounting a panel within an enclosure. Using one or more sets of mounting blocks, the panel and a frame of the enclosure can be secured together in respective horizontal orientations, then collectively rotated to a vertical orientation. The one or more sets of mounting blocks can include a set of stop blocks, each including a respective tongue, and a set of slide blocks, each defining a respective recess when seated on a frame member of the enclosure frame. Each tongue can be configured to nest within a corresponding recess when the mounting blocks secure the panel to a corresponding frame member.

Abstract: A thermal management system for an enclosure containing electrical components includes a thermoelectric cooling unit for controlling temperature inside the enclosure and a controller for the cooling unit, the controller being configured so that it can be installed within and protected by the enclosure, rather than requiring its own separate secure enclosure. The controller can further be installed within a housing of the thermoelectric cooling unit, which housing does not increase the footprint of the cooling unit. The housing can include a cover that separates the space within the housing into two compartments, with the controller mounted at an angle that allows the controller to fit within one of the compartments and under the cover.

Abstract: A float drain for an enclosure can include a basket to collect liquid from the enclosure, a sealing structure surrounding an outlet of the basket, and a float configured to seat against the sealing surface to prevent fluid flow out of the outlet and to rise off of the sealing surface due to buoyancy forces as the liquid collects in the basket. The float drain can include other features, including: ribs or other protrusions extending into an interior are of the basket to space the float apart from an inner wall of the basket; an angled orientation of the sealing surface; and a trough, at least partly defined by the sealing structure, to collect debris.

Abstract: Embodiments of the invention provide a rod guide for mounting a latch rod to an enclosure. A guide member can include a guide-member support surface and a guide opening to receive the latch rod. A base member can include a base-member support surface. The base member can support the guide member with the guide opening at different distances from the surface of the enclosure when the guide-member support surface is seated on the base-member support surface with the guide member disposed at different respective rotational orientations relative to the base member.

Abstract: Embodiments of the disclosure provide an encapsulated compressor overload, an encapsulated compressor relay start, an encapsulated head pressure control switch and a wiring diagram for a circuit for air conditioning units which prevent gases from being ignited by means of encapsulating sparking components, use of solid-state switching devices, and/or wiring circuits in such a way that open contacts do not contain enough energy to produce a spark capable of igniting the atmosphere.

Abstract: A apparatus for securing a shield body to one or more enclosures can include a plurality of mounting members configured to retain a plurality of fasteners at any of a plurality of locations along the mounting members. A first set of the mounting members can be secured to a second set of the mounting members, using a first set of the fasteners, at any of a plurality of locations along the mounting members of the first set. One or more enclosures can be secured to the second set of the mounting members, using a second set of the fasteners, at any of a plurality of locations along the mounting members of the second set.

Abstract: Embodiments of the invention provide an air conditioning unit and a ventilator. The ventilator has an impeller to draw outside air into an enclosure and cause air within the enclosure to be exhausted to the outside. The ventilator can be tied into the air conditioning unit's control system and act to supplement the cooling and ventilation needs of the space. Alternatively, the ventilator can have a separate integral control system. By having a separate control system, the ventilator can operate as a stand-alone device.

Abstract: A thermal management system for an enclosure containing electrical components includes a thermoelectric cooling unit for controlling temperature inside the enclosure and a controller for the cooling unit, the controller being configured so that it can be installed within and protected by the enclosure, rather than requiring its own separate secure enclosure. The controller includes a simplified power management circuit that uses an input quick connector that receives a first cable connector for providing power to the circuit board, and an output quick connector that receives a second cable connector for supplying power from the input quick connector to the fan of the cooling unit. This one-in, one-out arrangement allows for the elimination of multiple hard-wired cable harnesses and the corresponding connectors on the circuit boards of existing controllers. The circuit board size is reduced, and terminal blocks eliminated, so that the controller can be installed inside the enclosure.
