A system for direct injection of selected thermal-infrared (IR) wavelength radiation or energy into food items for a wide range of processing purposes is provided. These purposes may include heating, raising or maintaining the temperature of the food articles. The system is especially applicable to operations that require or benefit from the ability to irradiate at specifically selected wavelengths or to pulse or inject the radiation. The system is particularly advantageous when functioning at higher speeds and in a non-contact environment with the target.

A power assembly includes an internal combustion engine including an air intake line and an exhaust gas line having at least one heat exchanger. The power assembly further includes a Brayton cycle system capable of providing additional power to the main internal combustion engine and that includes a gas compressor, a fuel burning heater and a turbine linked to the compressor so that air is drawn into the compressor where it is pressurized, the pressurized air is further heated by flowing through at least one heat exchanger where it exchanges heat with exhaust gases from the main internal combustion engine, the heated and pressurized air is further heated by the fuel burning heater and is thereafter expanded through the turbine where a first fraction of the work extracted by the turbine is used to drive the compressor and a second fraction of the work extracted by the turbine is used to bring additional energy.

A cogeneration apparatus having a ventilation-introducing channel communicating an electrical-equipment compartment with a ventilation fan is disclosed. Driving the ventilation fan causes air to be led from an exterior of a cogeneration case through the electrical-equipment compartment to the interior of the ventilation-introducing channel. The air led to the interior of the ventilation-introducing channel is led to an electrical generator. The air led to the electrical generator is exhausted through a power-generation compartment to the exterior of the cogeneration case.

A fan unit (1), in particular for an air conditioning system of a motor vehicle, comprising an electric motor (2) for driving a fan wheel (3), an electronic device (7) which generates waste heat and provides electrical current to the electric motor (2) and a fan housing (6), wherein the fan wheel (3) is disposed together with said electric motor (2) in an air guiding region (5) delimited by the fan housing (6). Provision is thereby made for the electronic device (7) to be fastened to the side of the fan housing (6) which faces away from the air guiding region (5) in a heat transferring manner so that a heat transfer connection is formed between said electronic device (7) and said air guiding region (5).

A high-power LED package includes a thermal conductive substrate, a circuit layer formed on the top wall of the thermal conductive substrate, a LED chip mounted on the top wall of the thermal conductive substrate, lead wires electrically connected between the LED chip and the circuit layer, and a packaging layer covering the LED chip, the lead wires and the connection areas between the lead wires and the circuit layer outside the bottom wall of the thermal conductive substrate for enabling waste heat to be directly transferred from the LED chip to the thermal conductive substrate and then rapidly dissipated into the outside open air by the thermal conductive substrate during operation of the LED chip.

A cooling block (51) forming a top wall of a combustion chamber (19) of an internal combustion engine is formed by layering, from the outside to the inside, a casing (52), an upper layer block (53), a middle layer block (54), and a lower layer block (55). Labyrinth-shaped cooling water passages (53a, 54a, 55a) are formed on upper faces and side faces of the three layers of blocks (53, 54, 55), and cooling water supplied from a cooling water supply passage (56) flows from the cooling water passage (53a) on the side far from the combustion chamber (19) to the cooling water passage (55a) on the side close to the combustion chamber (19), and is discharged from a cooling water discharge passage (57). Since the cooling water flows in a direction opposite to the direction of emission of heat of combustion from the combustion chamber (19), it is possible to ensure that there is sufficient difference in temperature between a cylinder head (18) and the cooling water throughout the cooling water passages (53a, 54a, 55a), thereby improving the effect of the cooling water in cooling the cylinder head (18) and enabling the waste heat of the internal combustion chamber to be recovered effectively.

When driving an actuator 41 of an active vibration isolating support apparatus M to extend and contract on a predetermined cycle so as to suppress the transmission of vibrations of an engine, since a combined target current ICMDT is calculated by combining a primary target current which cancels a primary vibration of the engine with a secondary target current which cancels a secondary vibration of the engine and furthermore, the actuator 41 is driven with a target driving current ICMD in which a minimum value of the combined target current ICMDT is offset to 0, can the primary vibration and the secondary vibration of the engine be cancelled so as to enhance a vibration isolating function and the inclusion of a direct current component into the target driving current ICMD can be prevented so as to suppress a wasteful heat release of the actuator 41 to a minimum level.

A heat-dissipation apparatus for a hard disk is provided, which is adapted for being configured on a hard disk or in a hard disk slot, and includes a heat-conducting layer and at least one heat-conducting pad disposed on a surface of the heat-conducting layer corresponding to the hard disk. The heat-conducting pad contacts the hard disk and the waste heat is conducted from the hard-disk to the heat-conducting layer through the heat-conducting pad, and then transferred outside the hard disk or the hard disk slot through the heat-conducting layer. Therefore, the operating temperature of the hard disk in high speed operation is lowered and the service life of the hard disk is prolonged.

Provided are a defrosting control device, an air conditioner and a defrosting control method therefor. The device includes an airbag device, wherein the airbag device includes a mounting support (1), an airbag (2) and an inflation mechanism. When an air conditioner to be controlled enters a defrosting mode, the inflation mechanism inflates the airbag (2) such that same forms an airbag layer to isolate an outdoor heat exchanger of the air conditioner to be controlled from flowing air outside the outdoor heat exchanger. The defrosting control device can achieve the beneficial effects of a small defrosting heat loss, a good defrosting effect and a good user experience.
