Abstract:
A liquid cooled heat sink includes: a casing having a liquid inlet and a liquid outlet; and a fin unit provided in the casing and having a wave-like structure of a multi-fold sheet that defines a plurality of fluid paths which are aligned in series in a transverse direction relative to the fluid paths. The liquid inlet of the casing is in fluid communication with the liquid outlet of the casing through the fluid paths.
Abstract:
A heat dissipation device of a vehicle lamp and an interposing element thereof are provided. The heat dissipation device is installed in a lamp room which is divided by the interposing element into a front partition and a rear partition. A heat sink is installed in the interposing elements. An air feeding fan is disposed in an air feeding channel of the interposing element, for drawing air in the front partition to the rear partition through the air feeding channel. Further, a back flow fan is disposed in the rear partition, for drawing air in the rear partition to the front partition through a back flow channel. Whereby, the air in the front partition is cooled down through an external air flow passing through the lamp cover. Then, the heat sink dissipates heat of the air flow with the relatively low temperature in the front partition to the rear partition.
Abstract:
A liquid cooling device includes a liquid block, a heat-dissipating plate, a thermal-conductive pipe, a pump and a heat sink. The liquid block, the pump, and the heat sink are connected by ducts. The pump drives a coolant to circulate among them. The thermal-conductive pipe is mounted on the heat-dissipating plate. Both ends of the thermal-conductive pipe are connected to the liquid block for the coolant to flow through. The liquid block and the heat sink are respectively mounted on the corresponding electronic devices to absorb heat using the circulating coolant. The heat sink is used to dissipate heat from another heat-generating electronic device. Therefore, one less liquid block is required, and the production cost becomes lower.
Abstract:
A vehicle lamp has a lamp holder, an LED array, an interior heat sink and a heat exchanger. The lamp holder is hollow and has a heat conductive portion. The LED array is mounted in the lamp holder. The interior heat sink is mounted on the LED array and has an inner conductor attached between the LED array and the heat conductive portion. The heat exchanger is mounted on an outer side of the heat conductive portion. Therefore, the vehicle lamp can efficiently dissipate heat generated by the LED array by the interior heat sink and the heat exchanger with little or no dust entering the lamp holder and accumulating on the LED array for improved lifespan and constant heat dissipating performance.
Abstract:
A liquid cooling device for multiple electronic components has two liquid blocks, a heat-dissipating plate, a pump and a heat sink. The two liquid blocks and the heat sink are connected and communicated with other via tubing. The pump operates to make a coolant circulate among the two liquid blocks and the heat sink. The heat-dissipating plate is integrally formed with one liquid block. The heat-dissipating plate is disposed on another separate electronic component for absorbing heat. Therefore, the liquid cooling device has only two liquid blocks, but can dissipate heat generated by three electronic components.

A vehicle lamp has a lamp holder, an LED array, an interior heat sink and a heat exchanger. The lamp holder is hollow and has a heat conductive portion. The LED array is mounted in the lamp holder. The interior heat sink is mounted on the LED array and has an inner conductor being attached between the LED array and the heat conductive portion. The heat exchanger is mounted on an outer side of the heat conductive portion. Therefore, the vehicle lamp can efficiently dissipate heat generated by the LED array by the interior heat sink and the heat exchanger with little or no dust entering the lamp holder and accumulating on the LED array for improved lifespan and constant heat dissipating performance.
