Description

An apparatus and method for preventing the CPU overheating

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the prevention of overheating of CPI, which is a central processing unit to which a heat sink is attached for cooling. In general, CPI is a core component that performs various arithmetic processing in electronic devices such as computers. The high temperature heat is generated in the bar, and only when the high temperature heat is appropriately discharged to the outside to achieve a predetermined performance in the corresponding CPI, the high temperature is effectively released to the outside to reduce the surface temperature of the CPI. In order to detect whether the heat sink is normally attached to the outside of the CPI, the CPI is not overheated so as to perform a normal function smoothly.

Referring to these drawings, a conventional computer such as a computer using the CPI 4, which is a central processing unit, includes a printed circuit board 2 fixed by screws or the like inside the main body 1, and the printing A seed oil 4 is mounted on the circuit board 2 so as to perform arithmetic processing and the like, and a heat sink on the seed oil 4 for dissipating high temperature heat generated from the seed oil 4 to the outside of the seed oil 4. (3) is to be in close contact with / fixed, in order to improve the thermal conductivity between the CMP (4) and the heat sink (3) is typically coated / treated with a silicone grease (silicon grease) or a silicon adhesive sheet (sheet) Is used. In other words, the normal operation of CPI, which is a core component, is one of the main factors influencing the performance of the whole device. It becomes a task.

Here, the process of dissipating high temperature heat generated from the CPI 4 by the heat dissipation plate 3, the CPI 4, which is a central processing unit, performs a unique function such as arithmetic processing. The heat is generated, and in order to dissipate the heat, the heat sink 3 is usually adhered to and fixed on the C oil 4, and the heat generated from the C oil 4 is in contact with the heat sink 3. It is conducted to the heat sink 3 by the heat conduction action by the heat sink 3, and the heat sink 3 has a lot of heat radiation fins that act as a heat radiation on the surface of the heat radiation is generated efficiently.

If the heat sink for efficient heat dissipation is not attached to the seed oil, and the power is supplied to the seed oil to perform a unique function such as arithmetic processing, the seed oil 4 may initially operate normally. Even if a certain time passes, the surface oil (4) surface temperature rises over a certain temperature and overheats, thereby not only significantly lowering the processing speed of the seed oil by the high temperature heat generated from the seed oil, but also supplying the field with no heat dissipation. If the temperature inside the equipment continues to rise at CPI is broken by the high temperature heat will cause a problem that no further operation.

The present invention has been made in view of the above problems, and includes a sensing means for detecting whether the heat sink is normally mounted on the CMP oil and generating a detection signal. It is aimed to prevent the rise of the surface temperature of the seed oil by blocking it.

In addition, the method for preventing overheating of a computer C Seed oil according to the present invention comprises: a first step of transmitting a test signal by checking whether a heat sink is attached to the C Seed oil; Generating a control signal according to the received test signal; And a third step of controlling a power source for driving the CPI by a control signal.

Hereinafter, a preferred embodiment of an overheat prevention device and an overheat prevention method for a computer CFI fluid according to the present invention will be described with reference to the accompanying drawings.

Figure 3a is a view showing the main parts of the overheat prevention device equipped with a pressure-sensitive sensor according to the present invention, Figure 3b is a view showing the main parts of the overheat prevention device equipped with a light emitting / light receiving sensor according to another embodiment.

Referring to these drawings, the detection sensor (5) for detecting whether the heat sink is mounted on the seed oil is located on the upper side of the seed oil (4) as the contact between the seed oil and the heat sink, or the seed oil (4) ) Will be placed adjacent to it. In addition, the sensor 5 is preferably a pressure sensor, such as a push-switch (push-switch) for detecting a contact, but composed of a combination of the light receiving sensor and the light emitting sensor located on both sides of the heat sink You may.

First, referring to the operation of the sensor in the case of employing a pressure sensor, when the heat sink is mounted on the CPI with the pressure sensor 5, the sensor is generated by the heat sink. It detects this and generates a detection signal. At this time, the detection signal is a signal indicating that the heat sink is attached. On the other hand, if the heat sink is not mounted on the CPI with the pressure sensing sensor, the sensing sensor does not sense any pressure to generate a detection signal accordingly. The detection signal at this time is a signal indicating that the heat sink is not attached.

In addition, the pressure sensor may be placed in the vicinity of the outside of the CPI in addition to the above position, even when the pressure sensor is placed on the outside of the CPI, as the heat sink is mounted / coupled to the CPI, a predetermined portion of the heat sink is detected. By applying pressure to the sensor, a detection signal is similarly generated.

Referring to the operation of detecting whether the heat sink is mounted using a light receiving / light emitting sensor according to another embodiment, the light receiving / light emitting sensor is attached to the outer side of the CPI oil, and when the heat sink is mounted on the C F oil, the light emitting sensor is radiated by the heat sink. Inspection light emitted from (6) is blocked and eventually does not reach the light receiving sensor 7 so that the light receiving sensor 7 detects this and generates a detection signal. Here, the detection signal is a signal indicating that the heat sink is attached. On the other hand, if the heat sink is not mounted on the CPI attached to the light receiving / light emitting sensor, the detection light emitted from the light emitting sensor 6 is not blocked by the heat sink and passes through the light receiving sensor 7. The light receiving sensor 7 detects this and generates a detection signal. The detection signal is a signal indicating that the heat sink is not attached.
