Patent number: 11711911Abstract: 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.Type: GrantFiled: July 30, 2021Date of Patent: July 25, 2023Assignee: Hoffman Enclosures Inc.Inventors: Shawn A.

Patent number: 10954695Abstract: 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.Type: GrantFiled: August 16, 2018Date of Patent: March 23, 2021Assignee: Hoffman Enclosures, Inc.Inventors: William Anderson, Kevin Roof, Krystal Jamison, Alkhalil Alkindi, Taylor Farber, Csaba Andrasfi

Patent number: 10502463Abstract: 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.Type: GrantFiled: September 11, 2018Date of Patent: December 10, 2019Assignee: Hoffman Enclosures, Inc.Inventors: Shawn Thao, Jason Dickmann, Victor Divine, Michael Rasmussen
