[summary of the invention]
The purpose of this utility model is to provide a kind of lower-cost radiator.
Further purpose of the present utility model is to provide a kind of pyroconductivity higher, the radiator that the heat that heater element produces can be lost rapidly.
The purpose of this utility model is achieved through the following technical solutions: radiator of the present utility model, comprise a holder and be located at radiator on this holder, wherein this holder comprises that one is provided with heat radiation frame, an absorber plate of through hole and is located at heat transfer plate on this absorber plate, and this absorber plate is fixed in the through hole on the heat radiation frame.
The utility model radiator also comprises at least one heat pipe, and this heat pipe is with absorber plate and heat transfer plate is hot is connected.
Because the utility model radiator is fixed in absorber plate and heat transfer plate in the heat radiation frame, so absorber plate, heat transfer plate can be selected different materials as required with the heat radiation frame, thereby make the cost reduction of radiator.In addition, because heat pipe is with absorber plate and heat transfer plate is hot is connected, thus the heat of absorber plate absorption can be passed to radiator rapidly, thus the pyroconductivity of raising radiator.
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
