1. Field of the Invention
The present invention relates to a thermal module, which can dissipate the heat of multiple heat sources at the same time to achieve thermal homogeneity of the heat sources and lower the material cost and assembling cost.
2. Description of the Related Art
Along with the advance of sciences and technologies, the operation performances of electronic components have become higher and higher. Accordingly, higher and higher heat dissipation efficiency of the heat dissipation unit is required. The conventional heat dissipation unit generally employs a stack-type radiating fin assembly for increasing the heat dissipation efficiency. Moreover, various improved radiating fins have been continuously developed. It has become one of the most important topics in this field how to develop high-performance heat dissipation units. The heat dissipation unit is arranged on the electronic component for dissipating the heat generated by the electronic component. The heat dissipation unit generally includes a heat sink or a radiating fin assembly and a cooperative cooling fan for carrying away the heat. Furthermore, the radiating fins can be stringed with a heat pipe to transfer the heat to a remote section for dissipating the heat.
With a computer mainframe taken as an example, most of the heat is generated by the central processing unit (CPU) of the computer mainframe. In the case that the heat is not dissipated in time, the temperature of the CPU will rise to cause deterioration of the execution performance of the CPU. When the heat accumulates to an extent higher than the tolerance limit, the computer will crash or even burn out. Moreover, in order to solve the problem of electromagnetic radiation, the computer mainframe is generally enclosed in a computer case. Therefore, it has become a critical issue how to quickly dissipate the heat generated by the CPU and other heat generation components.
The current thermal module is composed of multiple heat dissipation components, which cooperate with each other to dissipate the heat. The heat dissipation components include heat pipe, heat sink and heat dissipation base seat. However, in general, multiple CPU or heat generation units are arranged inside the computer case. All these CPU or heat generation units will generate high heat in operation. These CPU or heat generation units are generally forward and backward arranged at intervals. In addition, each of the CPU or heat generation units is provided with a thermal module. A cooling fan is used to blow air to the thermal modules for carrying away the heat. However, after the airflow passes through the front end thermal module, the temperature of the airflow will apparently rise. It is known that the outgoing airflow of the front end thermal module is exactly the incoming airflow of the rear end thermal module. Accordingly, the incoming airflow at high temperature can hardly effectively dissipate the heat generated by the rear end CPU or heat dissipation unit. Therefore, it is necessary to additionally provide a cooling fan for the rear end thermal module or enhance the performance of the rear end thermal module so as to effectively dissipate the heat of the rear end thermal module. This will lead to increase of material cost and assembling cost. According to the above, the conventional thermal module has the following shortcomings:
- 1. The conventional thermal module cannot dissipate the heat of multiple heat generation units at the same time.
- 2. The material cost and assembling cost are higher.
It is therefore a primary object of the present invention to provide a thermal module, which can dissipate the heat of multiple heat sources at the same time to achieve thermal homogeneity of the heat sources.
It is a further object of the present invention to provide the above thermal module, which can dissipate the heat of multiple heat sources at the same time to lower the material cost and assembling cost.
To achieve the above and other objects, the thermal module of the present invention is for assembling with multiple heat sources. The thermal module includes at least one heat dissipation base seat, at least one first heat pipe and at least one first radiating fin assembly.
The heat dissipation base seat has at least one first insertion section and at least one second insertion section in communication with the first insertion section. The first insertion section is mated with the heat sources. The first heat pipe is mated with the second insertion section. Two ends of the first heat pipe respectively extend to the first insertion section to attach to the heat sources. The first radiating fin assembly is disposed on the heat dissipation base seat and attached to the first heat pipe. A second radiating fin assembly is disposed on the first heat pipe. The second radiating fin assembly extends to connect and assemble with the first radiating fin assembly on the heat dissipation base seat. Accordingly, the thermal module can dissipate the heat of the multiple heat sources at the same time to achieve thermal homogeneity of the heat sources and lower the material cost and assembling cost.
According to the above, the present invention has the following advantages:
- 1. The thermal module of the present invention can dissipate the heat of multiple heat sources at the same time to achieve thermal homogeneity of the heat sources.
