An conditioning system is shown for a helmet having an impact resistant body with an exterior, an interior which defines a head receiving cavity, a front region and having a back region which is located adjacent a lower edge of the helmet body. A first opening is provided in the helmet body located at the back region of the helmet body adjacent a lower edge thereof which acts as an air intake opening. A blower fan communicates with the air intake passage for drawing air into the intake passage and forcing the air from the back region of the helmet in the direction of the front region thereof. A thermoelectric cooling element is located in the helmet interior in communication with the intake passage downstream of the blower fan. The thermoelectric cooling element has a cold side and a hot side. A DC power source is provided for powering the thermoelectric cooling element. An external heat sink is located on the helmet exterior and is connected to the hot side of the thermoelectric cooling element by means of a second opening in the helmet body. Air passing over the thermoelectric cooling element is cooled and air conditions the head receiving region of the helmet.

Active cooling technologies such as thermoelectrics can be used to introduce thermal “gain” into a cooling system and, when employed in combination with forced flow cooling loops, can provide an attractive solution for cooling high heat flux density devices and / or components. In such configurations, it can be advantageous to discontinuously flow thermal transfer fluid into thermal contact with the hot or cold side of a thermoelectric module (TEM), allow it to dwell while heat is transferred from or to the TEM, and resume the flow. In configurations in which the TEM operation is itself discontinuous, various relationships between thermal transfer fluid flow and TEM operation can be advantageously employed to temporally integrate thermoelectric action.

The thermoelectric heat pump comprises one or more thermoelectric modules having a hot side connected to a first heat exchanger and a cold side connected to a second heat exchanger, and is characterized in that it comprises a pair of elongated bar-like elements made of an electrically and thermally insulating material which are arranged at two parallel sides of the heat exchangers, at least partly interposed between facing flanges of said heat exchangers, at least one of said elongated bar-like elements including electric conductors for supplying power to the thermoelectric modules, as well as conductors for supplying control signals therefor, and that said heat exchangers contacting the thermoelectric modules are linked one another via a plurality of fasteners, each fastener being formed of a substantially C-shaped metal clip.

The disclosure relates to a unitary heat pump air conditioner (Unitary HPAC) that includes a refrigerant loop having a condenser, a refrigerant expansion device, and an evaporator hydraulically connected in series. An electrically driven compressor is provided to circulate a two-phase refrigerant through the refrigerant loop to transfer heat from the evaporator to the condenser. The unitary HPAC also includes a cold side chiller configured to hydraulically connect to a cold side coolant loop and is in thermal communication with the evaporator. The unitary HPAC further includes a hot side chiller configured to hydraulically connect to a hot side coolant loop and is in thermal communication with the condenser. The refrigerant loop transfer heat from the cold side chiller to the hot side chiller, thereby cooling the cold side coolant loop and heating the hot side coolant loop. The components of the unitary HPAC are mounted on a common platform.

A system enclosure uses two heat exchangers and a thermoelectric cooling module to manage heat within the system. An airflow enters the system and is heated by server blades. Portions of the airflow split and travel to various portions of the system enclosure. Some heat is removed from the airflow by passing through the first heat exchanger before circulating around downstream subsystems. The first heat exchanger contacts the cold side of a TEC module, to reduce the temperature of that airflow. The air then enters the network switch module or other subsystem where it is further heated. Thereafter, the second heat exchanger ‘bypasses’ those components by reinserting the upstream heat back into the downstream airflow. The second heat exchanger contacts the hot side of the TEC module. The mixture of all heated air is then expelled from the system enclosure.
