Description of the Invention: [Technical Field] The present invention relates to a natural convection ambient temperature simulation test box, and more particularly to a test box structure capable of accurately simulating an ambient temperature to facilitate various performance tests of a product. [Prior Art] The ambient temperature simulation test box structure of the present invention is provided with an air supply device in an oven, which is heated by the oven to generate an appropriate temperature rise (to reach a certain temperature: ), and the air supply device (fan) generates air convection, so that The oven has a relatively uniform temperature at each position to simulate different ambient temperatures to facilitate testing of various characteristics; however, the above structure has the following drawbacks in practical applications: 1. Due to the air supply device (fan) The generated air convection system is directly in contact with the object to be tested, so that it is easy to have a forced airflow of the airflow, which affects the Φ reliability and the quasi-rotation property of the test. 2. Since the inside of the oven is a confined space, not only the wiring and operation during testing are not easy, but the internal conditions of the oven are difficult to grasp and the operation risk is high. In addition, it is heated to a predetermined temperature in a confined space, and is slowly cooled down, and tested during the slow cooling process; this method is not suitable for testing because the ambient temperature of the simulation is at any time (decreased). Accuracy. In view of the above-mentioned shortcomings of the ambient temperature simulation test box structure, the inventors have studied the improvement of these shortcomings, and finally the invention produces 1259272. SUMMARY OF THE INVENTION The present invention aims to provide a natural convection ambient temperature simulation test box, including: a box body, a partition plate, a heating device and the like, wherein the box system is covered on a base, at least one periphery of the box body The bottom bottom portion is provided with an air inlet, and at least one air venting hole is disposed above the air inlet port, and the partitioning plate is made of an insulating material, and the at least one supporting body is supported on the base, so that the separating plate is ^ The base is formed at a distance, and the object to be tested is placed above the partition plate; the heating device is disposed between the partition plate and the base, and can be separated from the object to be tested by the partition plate The heating device generates heat to heat the air flowing in from the air inlet of the box body, and the heated hot air rises and evenly diffuses in the space above the box body, and is further discharged outward from the vent hole to form a stable The simulation test environment can avoid the situation that the airflow is forced to dissipate heat, and the test accuracy is effectively improved, which is the main purpose of the invention. According to the natural convection ambient temperature simulation test box of the present invention, the wiring and operation during testing can be simplified, and the internal condition can be easily grasped, and the operational risk can be effectively reduced. This is another object of the present invention. The detailed construction, the application principle, the function and the effect of the present invention can be fully understood by referring to the following description of the drawings: [Embodiment] The first drawing is an exploded view of the structure of the present invention, and the second drawing is referred to A schematic diagram of the combination, it can be clearly seen that the present invention mainly comprises: a box 1 1259272, a partitioning plate 2, a heating device 3, etc., wherein the housing 1# a housing, the cover 5 can be placed on the base 14 An air inlet 12 is provided at a bottom of at least one side of the periphery of the casing 1 , and at least one vent hole i 3 ′ is disposed above the air inlet i 2 at least one side of the casing 1 On the door panel, the isolation plate 2 is made of heat-insulating material, and the support body 2 1 is supported on the base 1′4, so that an appropriate distance is formed between the separation plate 2 and the base 丄4, ^ Ik The object to be tested is placed on the upper side of the plate 2, and the force σ heat device 3 is disposed between the partition plate 2 and the base 14 (the temperature is controlled by a temperature control device f1), and the heat can be utilized. The isolation plate 2 forms a barrier with the object to be tested to isolate heat conduction such as radiation and direct heat convection. . The third and fourth figures are not intended to be used in the test of the present invention and the air convection thereof. As shown in the two figures, the object to be tested 5 may be placed above the insulation plate 2 during actual testing. The temperature control device 3 controls the heating to generate heat to heat the air in the tank 1. The heat after heating is increased and uniformly diffused in the space above the tank body, and gradually discharged from the exhaust hole and outward, and fresh The air flows into the casing 1 from the air inlet 12: the charging is used to form a stable heat balance, and the test environment of different temperatures can be simulated; 'The invention isolates the object to be tested 5 and the heating device 3 by the separating plate 2 The heat conduction between the heat and the direct heat convection is caused by the heating of the air in the tank 1 to generate an indirect convection to form a stable balance, thereby achieving an optimal environmental simulation effect. In order to effectively improve the accuracy of the measurement. It can be seen from the above that the natural convection environment temperature simulation test of the present invention 1259272 box has the effect of accurately simulating the ambient temperature and being simple and safe to operate, and has indeed been industrially utilized, novel and progressive. However, the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
