Water-cooled car lamp device

Abstract

The invention discloses a water-cooled car lamp device. The water-cooled car lamp device comprises a lamp seat, a lamp bulb, a heat-radiating seat and heat-radiating fins. The water-cooled car lamp device is characterized in that the device also comprises heat-radiating tubes which orderly penetrate through all the heat-radiating fins, a cooling box arranged in the lamp seat in a sleeving manner and adjacent to the heat-radiating seat; and two partition sheets are equipped with temperature sensors. The car lamp device is equipped with the heat-radiating seat which is provided with the heat-radiating fins used for heat radiation. Therefore, the basic heat-radiating effect is achieved. Cooling tubes and cooling boxes, contacting all the heat-radiating fins are additionally arranged. The heat-radiating fins are cooled down through a water-cooled manner. In order to enhance cooling effect, each cooling box is equipped with two box bodies holding cooling liquid. The temperature sensors control and alternatingly intervene into the cooling tubes in order to ensure that heat exchange between one box body and the heat-radiating fins is realized and the other box body always radiate heat inthe static state. When temperature in the box body subjected to heat exchange is high, a low-temperature box body intervenes into the cooling tubes. Therefore, the cooling effect is greatly enhanced.

Description

technical field [0001] The invention relates to a water-cooled vehicle lamp device. Background technique [0002] With the rapid development of the automobile industry, while people are pursuing comfort and ease of handling, more and more attention has been paid to the overall safety, energy saving and environmental protection of automobiles. In this regard, car lights now mostly use LED lights and adopt planar cluster packaging technology, which can meet the requirements of high power and low energy consumption; however, the interior of car lights is a closed environment. When the car headlights are in the lighting state, The airtight environment where the car lights are located will generate a higher temperature due to heat accumulation. This higher temperature will not only easily generate fog inside the car lights and affect the lighting effect, but also easily cause the parts in the car headlights to be heated and deformed. , and even the phenomenon of parts melting; a...

Problems solved by technology

In this regard, car lights now mostly use LED lights and adopt planar cluster packaging technology, which can meet the requirements of high power and low energy consumption; however, the interior of car lights is a closed environment. When the car headlights are in the lighting state, The airtight environment where the car lights are located will generate a higher temperature due to heat accumulation. This higher temperature will not only easily generate fog inside the car lights and affect the lighting effect, but also easily cause the parts in the car headlights to be heated and deformed. , and even the phenomenon of parts melting; at present, using a radiator to cool down is a common way of heat dissipation

[0003] The radiator selected by the car lamp in the prior art is a conventional radiator, and its heat dissipation effect is relatively poor.
