Description

  The present invention relates to a heat radiating module, and more particularly, to a heat radiating module that is configured by simply combining and combining heat radiating devices without welding.

  Conventional heat dissipation devices and heat dissipation modules are formed by combining a plurality of heat dissipation devices. The heat dissipating device is a device such as a heat pipe, a heat dissipator, or a heat dissipating base, and the mutual coupling is performed by welding or the like. However, when welding a heat radiating device made of aluminum, a special welding technique is required, which causes an increase in cost.

  On the other hand, the heat dissipation device may be coupled by a fixing device such as a screw. The coupling by the fixed device is effective for some heat radiating devices such as a heat radiating base and a heat radiating fin, but cannot be used for a heat pipe.

  Therefore, in the prior art, in order to connect the heat pipes, holes or grooves are provided in the heat radiating base and the heat pipes are inserted. Thereby, a heat pipe and a heat radiating base are combined, and the problems caused by the above welding and screw tightening are solved.

  Patent Document 1 discloses a heat pipe fixing method.

  However, in the method of conducting the heat of the heat pipe indirectly through the heat dissipation base, if there is a gap between the two, a thermal resistance is generated and the heat conduction efficiency may be reduced.

  An object of the present invention is to provide a heat radiating module capable of improving heat conduction efficiency and quickly radiating heat with a heat pipe disposed on a base.

  In order to achieve the above object, a heat dissipation module according to one aspect of the present invention includes a first plane provided with at least one groove and a second plane provided with a recess, and the groove and the recess are mutually connected. The base is in communication, and at least one heat pipe arranged to correspond to the inside of the groove.

  According to the heat dissipating module of the present invention, heat conduction efficiency can be improved and heat dissipated by the heat pipe disposed on the base can be quickly performed.
