Embodiment Construction

[0035] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and fully convey the scope of the invention to those skilled in the art.

[0036] Figure 1-3 A heat transfer device generally indicated with reference number 1 is shown. The heat transfer device 1 comprises a heat spreader 2, which is a so-called second-level contact block, made in this embodiment of aluminum. The heat transfer device 1 further comprises a heat transfer plate 3 which is a so-called primary contact block, here also made of aluminium. The heat spreader 2 is here mechanically connected to the heat transfer plate 3 by four elastic elements in the form of springs 4 . ...

Abstract

A heat transfer device for transferring heat to a housing,comprising a heat spreader,at least one heat transfer plate mechanically connected to the heat spreader so as to be resiliently compressible towards the heat spreader when brought into contact with the housing, and at least one heat pipe thermally connected to each heat transfer plate and to the heat spreader. The resilient compressibility of the heat transfer plates makes the heat transfer device flexible, such that it may adapt to a different shape of housing.In contrast to known thermal interfaces, the thermal interface of the heat transfer device of the invention is not mechanically connected to the housing in which it is used, but connected to the heat spreader, and may instead be pressed into contact with the housing, without mechanical fixation. Fig.

Description

technical field [0001] The invention relates to a heat transfer device, a luminaire comprising the heat transfer device and a method of assembling a luminaire. Background technique [0002] In new applications of LED lighting, such as street lamps and automotive lamps, high-power light sources are often used. With current LEDs, this results in significant heat generation, on the order of several hundred watts. This heat must be transported away from the light source, otherwise the light source will deteriorate. The heat is dissipated over a large surface of a so-called heat spreader, from which it can be dissipated into the ambient air. Heat spreaders are usually made of metal and may also be referred to as heat sinks. [0003] One possible solution to the problem of transporting heat away from the light source is to use a ventilator. However, ventilators have moving parts that can be damaged. Furthermore, the use of ventilators leads to increased costs both for manufac...
