Description of the Invention: [Technical Field] The present invention relates to the field of heat dissipation, particularly relating to a method and apparatus for detecting heat pipe performance. [Prior Art] As a heat dissipating application, the heat pipe is widely used in the fields of electronics, automobiles, aviation, and chemicals because of its fast heat transfer characteristics. It is filled with a proper amount of working fluid in a casing that is drawn into a low pressure. The working fluid works on the principle of absorbing or releasing a large amount of heat during the gas-liquid two-phase transformation. The inner wall of the casing is usually provided with a capillary structure for facilitating the reflux of the condensed liquid to provide the driving force required for the liquid to accelerate the recirculation after condensation. In use, one end of the heat pipe (evaporation section) is placed at a high temperature heat source, and the working fluid in the casing is heated to evaporate into a gaseous state. The steam flows through the cavity in the casing to the other end of the heat pipe (condensing section) and is discharged. The heat is condensed into a liquid state, and the condensed liquid is quickly returned to the evaporation section under the adsorption force of the capillary structure of the inner wall of the casing, and then the next working cycle is performed, thereby transferring heat from one place to another. In order to meet the performance requirements of the heat pipe when it is put into use, it is usually necessary to pass a specific performance test before putting the heat guide into service to ensure that the heat pipe can meet the requirement and maintain a certain level in actual use. Performance stability. The first figure shows a two-end temperature difference test method for performance testing of heat pipes in the industry. The method tests the temperature difference parameter (ΔΤ) at both ends of the thermal guide 1 to determine whether the performance of the heat pipe 1 meets the requirements. In the test process, the heat pipe 丨 evaporation section is immersed in the constant temperature water tank 2, and after a certain time interval, the temperature Τ and I of the evaporation section and the condensation section are respectively measured, and the temperature difference ΔΤ between the two ends is obtained, and if the ΔΤ is smaller than a certain If the value is specified, the performance of the heat pipe is judged to be acceptable, and if it is determined, the test is unqualified. Although the test method is relatively simple, it cannot detect the actual input heat of the heat source to the heat pipe, and some of the defective products whose heat conduction amount is lower than the design specification may be misjudged due to the small amount of Δ.曰 6 1257478 SUMMARY OF THE INVENTION In order to solve the technical problem that the actual heat input of the heat pipe and the temperature difference between the two ends cannot be detected at the same time, it is necessary to provide a heat pipe performance detecting method and a detecting device for the actual input of the heat pipe. The heat and the temperature difference between the two ends are simultaneously detected. The heat pipe performance detecting method comprises the steps of: providing a heating device and a cooling device, and respectively setting an evaporation section and a condensation section of the heat pipe to be tested on the heating device and the cooling device; and using the heating device to the evaporation segment Heating to the heat pipe to reach the operating temperature and using the cooling device to cool the condensation section to maintain the heat pipe in an operating state; determining whether the heat input by the heat-increasing device to the heat pipe evaporation section is greater than a specified value, if greater than the specified value Then, the heat pipe is tested for temperature difference between the two ends and it is determined whether the heat pipe is personality. The heat pipe performance detecting device comprises: a heat conducting block for transferring heat to the strip sending section of the heat pipe to be tested; a heating source disposed in the heat conducting block and transmitting heat along the heat transfer block through a heat transfer direction Heating the evaporation section of the heat pipe; cooling the cooling section of the heat release to be tested; the first temperature measuring device for testing = temperature in the heat block at three points along the heat transfer direction a second temperature measuring device for detecting a temperature difference between the thermal section and the condensation section; an electronic module capable of deriving the heat conduction block to the heat pipe by the three-point temperature measured by the first temperature measuring device The heat value input in the evaporation section, and # starts the second temperature measuring device to perform the measurement work when the value is greater than a certain value. The above-mentioned thermal conductivity test method and detection device can simultaneously detect the heat actually transmitted to the thermal guide burst section and the temperature difference between the two ends, and perform detection on the basis that the heat pipe meets a certain heat transfer amount, and will not If the amount of heat-reducing material is lower than the customer's requirements, the defective product is misjudged, and the test time is short. It can be applied to the full inspection of mass production, which is in line with economic production demand. σ [Embodiment] The first figure is not the test principle of the performance test of the heat pipe of the present invention, and mainly includes the bracket 10 and the test body portion provided on the bracket 10. The test body includes a heating device 2〇 and a cooling device 30 for separately performing heating and cooling on the heat pipe 9〇, and a temperature measuring device for measuring temperature (see below). The heating device 20 includes an electric heating rod 21, a thermally conductive copper block 22, and a heated copper block 23. The heat conducting copper block 22 is a vertically placed cylindrical structure. The electric heating rod 21 is vertically disposed in the same direction as the heat conductive copper block 22 and is embedded in a middle portion of the lower half of the heat conductive copper block 22, and can input heat through the DC power supply 24 and conduct the heat conductive copper block 22. heating. The heated copper block 23 is placed directly above the thermally conductive copper block 22 and has a larger cross-sectional area. In order to prevent the heat absorbed by the heat conductive copper block 22 from being radiated to the atmosphere, the first heat insulating layer 25 composed of fiber glass is disposed on the periphery and the bottom of the column of the heat conductive copper block 22, and the first heat insulating layer 25 is provided in the first heat insulating layer 25 The second heat insulating layer 26 made of insulating bakelite is further provided. Of course, the first heat insulating layer 25 and the second heat insulating layer 26 can also be made of other materials with good thermal insulation properties, such as asbestos (asbestos). )Wait. Thereby, the heat absorbed by the heat conductive copper block 22 can be transmitted to the heating copper block 23 by transmitting along the longitudinal direction of the heat conductive copper block 22 and the contact interface 27 of the heated copper block 23, of course, the heat conductive copper block 22 The heating copper block 23 can also be formed as a unitary structure, so that unnecessary thermal resistance can be reduced on the contact interface 27 of the two. The evaporation section 91 of the heat pipe 90 is attached to the heated copper block 23 during the test. The cooling device 30 includes a cooling copper block 31, a heat sink 32, and a water tank 33. Wherein, the cooling block 31 is in heat transfer contact with the condensation section 92 of the heat pipe 90 and transfers heat to the heat sink 32 located below to dissipate the heat pipe 90 to maintain normal operation during testing. The cooling device 30 dissipates heat by means of water circulation cooling. Therefore, the radiator is usually provided with a flow passage (not shown) through which water is supplied to enhance the heat dissipation effect. In order to test the heat pipe 9 in a horizontal position during testing and to apply different lengths of heat pipes, the cooling device 30 further includes an adjusting device 34 for adjusting the height of the cooling copper block 31 and the heat sink 32 and horizontally moving relative to the bracket 10. To adjust to the desired position and facilitate testing. The temperature measuring device includes a first temperature measuring device for measuring three different temperature values of the heat conductive copper block 2 in the longitudinal direction thereof, and A, T3, and a second temperature difference for measuring the temperature difference between the two ends of the heat pipe 9 Temperature measuring device. Wherein, the first temperature measuring device can be two thermocouples inserted at the measuring points in the heat conductive copper block 22. The second temperature measuring device can be two thermocouples, respectively disposed at the position of the evaporation section 91 and the condensation section 92 of the heat pipe 90 and can be moved up and down by the two cylinders 42 at a vertical position of 1257478, for measurement. The two cylinders 42 cause the second temperature measuring device to simultaneously press and detect the temperature across the heat pipe 90. By measuring the temperature values ΤΙ, T2, T3, the electronic module 5 with data processing capability and control function built in the test machine, such as a central processing unit, can be used to calculate the thermal copper block 22 and the heated copper. The temperature Tease at the location of the contact interface 27 of the block 23 and the heat transferred to the heated copper block 23 via the interface 27 are based on the assumption that the thermally conductive copper block 22 is a one-dimensional heat transfer, that is, heat is transferred only to the heated copper block 23 along its longitudinal direction. The temperature distribution along the longitudinal direction of the thermally conductive copper block 22 is represented by a quadratic curve as: T(x)=axx2+b><x+c (1) (wherein a, b, c are constants, and X is heat conduction The distance between the copper block 22 and the electric heating rod 21 at any position in the longitudinal direction directly above the electric heating rod 21 is substituted into the actually measured three-point temperature value, T2, T3, and the distance from each point to the electric heating rod 21, respectively. In the above formula (1), a, b, and c can be calculated, so that the temperature value of the thermally conductive copper block 22 at any position in the longitudinal direction from the electric heating rod 21 can be calculated under the specific condition. From equation (1), the heat transfer coefficient Q of the heat conductive copper block 22 along its longitudinal direction at any position can be obtained as follows: Q(x)=k XAX dT (x)/dx=kx A χ (ax 2 χ x+b) (2) (where k is the heat transfer coefficient of the heat conductive copper block 22, A is the cross sectional area of the heat conductive copper block 22, and X is the heat conductive copper block 22 at any position in the longitudinal direction directly above the electric heating rod 21 to The distance between the top end of the heat-conductive copper block 22 and the electric heating rod 21 is substituted into the above two formulas (1) and (2), respectively, and the heat conductive copper block 22 and the heated copper block 23 interface 27 can be calculated. The temperature T at the place and the heat Qease transmitted to the heated copper block 23 via the interface 27. In the process of detecting the heat pipe 90, the evaporation section 91 and the condensation section 92 of the heat pipe 90 are placed on the heating copper block 23 of the heating device 20 and the cooling copper block 31 of the condensing device 30, respectively. For the evaporation section 91, a preferred arrangement is to open a groove on the heating copper block 23 to embed the evaporation section 91 in the groove, and apply a heat conductive medium such as a thermal conductive adhesive to the groove to increase evaporation. The heat transfer effect between the segment 91 and the heated copper block 23. The two-point temperature values I, I, and D, which are obtained by the first temperature measuring device at any time, are substituted into the above formula (1), and the thermally conductive copper block 22 and the heated copper block 23 can be obtained at that time. The temperature at the interface 27 is slightly off and the heat Qease transmitted to the heated copper block 23 via the interface. The heat value Qcase minus the heat Q emitted by the heated copper block 23 is the actual evaporation portion 91 of the heat pipe 9〇. The absorbed heat Qin, and the heat Q' emitted by the heated copper block 23 can be controlled according to the input heat of the DC power supply 24 under the no-heating of the test machine 9 (7), and the heating copper block is controlled. 23 When the surface temperature is at a certain temperature, such as 6 (rc, and is in thermal equilibrium with the surrounding environment, the input heat of the DC power supply 24 at this time is the heat dissipated by the heated copper block 23 at the specific temperature condition. By setting the surface temperature of the heated copper block 23 to the operating temperature of the heat pipe 9〇, the heat quantity Q emitted by the heat pipe 9 when the copper block 23 is heated during operation can be measured. The heat conduction amount of the heat pipe and both ends Important reference in the performance test of temperature difference heat pipe The test body portion of the present invention can simultaneously detect the two parameters. In the test experiment, it is assumed that the heat transfer amount of the heat pipe 9 turns according to the actual working environment or customer requirements must be greater than 40 W, and the heat pipe 90 is assumed. The operating temperature is (9), and the thermal conductivity test is performed under the premise. The test process is as shown in the third figure, and the heat is gradually input to the heat conductive copper block 22 through the electric heating rod 21 by the DC power supply 24, and is started. The first temperature measuring device measures the three temperature values of the heat conducting copper block 22, D2, and τ3, and the interface between the heat conducting copper block 22 and the heating copper block 23 is calculated by the above formula (1). The temperature Tcase at 27, when the Tcase value is less than the operating temperature of the heat pipe 90 is 6 〇 t, the heating is continued until the Tease value calculated by the three-point temperature values T!, A, D, 3 obtained by the re-detection is equal to Or greater than the operation of the heat pipe 90's degree 60C, such as a Tcase value of 65 ° C. At this time, through the heat input of the heated copper block 23, the heat pipe 90 will start the working fluid because of the operating temperature (eight) Actuate while heating copper 23 will gradually reach thermal equilibrium with the surrounding environment and substantially maintain the heat dissipation value at (8) it (ie, the operating temperature of the heat pipe 90). 纟 The DC power supply % continues to supply heat, which will cause the actual input of the heat pipe 90 The heat Qm increases, and the value of the Qin is greater than 40 W. At this time, the heat pipe 90 works in the environment required by the customer, and the performance parameter of the heat pipe 90 can be detected, that is, according to the first temperature measuring device at this time. The three 1257478 jade binary values η, I, are substituted into the heat transferred to the heated copper block via the interface 27 calculated by the above two formulas minus the amount of heat generated by the heated copper block 23 at the operating temperature of the heat pipe, that is, 6〇1. When the heat value Q|n of the input heat pipe obtained by Q' is greater than 4_, the two cylinders 42 cause the temperature of the two ends of the heat pipe 9g to be detected by the second temperature measuring device of the thermocouple, and the two cylinders are found. When the temperature difference ΔΤ is less than a predetermined value (generally H), the measured heat pipe 90 is judged to be qualified, and if it is determined to be unsatisfactory. The tester uses the first and second heat insulating layers 25, 26 to prevent heat loss of the heat conducting block 22 for heating, f uses real-time calculation to obtain the heat transferred from the heat conducting block 22 to the heating block 23, and simultaneously heats up The heat Q that is lost to the environment in block 23 is fully considered, so that the accuracy of calculating the actual heat input Qin of the heat pipe is improved. During the entire test process described above, the cooling device 3 妨 will be miscellaneous in the condensation section of the heat pipe, and the amount of water can be adjusted according to the size of the required gap, and the conduit 90 is straightforward. In addition, the reading and transmission of each test data and the control of the DC power supply ||24 the input and cooling device % water amount and the start of the first test / dish device can be passed throughout the test process. The built-in electricity of the test machine = the automatic control of the block 50 is completed without the need for the operator to be fine. After each marriage test is completed, f author takes out the heat guide 9〇, and when the heat conductive copper block 22 or the heated copper block 23 is lowered to the φ core of the heat pipe 9〇 as the temperature below 60 ° C, the new one can be continued. test. Month. The test principle disclosed in the example can simultaneously detect the actual heat delivered, the heat of the evaporation section 91 of the official 90 and the temperature difference between the two ends, which can be used to detect the heat pipe 90 on the basis of satisfying the minimum heat transfer. The detection is accurate and there is no defect that the heat conduction is lower than the customer's request. The situation where the mouth is misjudged occurs, and the test time is short (about _less), and multiple detection devices can be set to simultaneously detect multiple heat pipes, thereby improving the yield and making a full inspection of the large τ production. Economic production demand; in the test software, this k / then sigh $ can be displayed or printed in the form of a dynamic curve of the test by the display screen, which brings convenience to the analysis data. In many cases, the field can be changed or adjusted to a certain extent. For example, the value of the dish at 27 can also be directly detected by the temperature measuring device without the need for 1257478 diameter = The formula (1) is used for calculation. The invention can also be used for detecting the temperature by using other methods such as a thermometer, an infrared thermometer, and the like, and heating the copper block 23, the heat conductive copper block 22, and the cooling copper block 3, etc. can also be selected as a copper alloy, g and shouting other materials with good thermal conductivity. Further, the cooling device 30 may use other cooling methods such as air cooling. ▲ In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law.
