DETAILED DESCRIPTION

[0044] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0045] In the present disclosure, the orientation words such as "up, down, top, bottom" are defined based on the direction of gravity of the air-conditioning experimental device, wherein up corresponds to top and down corresponds to bottom. "Inner, outer" refers to the inner and outer of the contour of each component. The terms "first, second" are used to distinguish one element from another element, and do not have sequentiality and importance. In addition, the following description, when referring to the drawings, the same reference signs in different drawings represent the same or similar elements, and the present disclosure does not make redundant descriptions.

[0046] According to some embodiments of the present disclosure, an air-conditioning experimental device is provided, referring to Figure 1 ​As shown in FIG. 1, the air conditioner test equipment includes an inner machine chamber 11 and an outer machine chamber 12, the inner machine 10 is arranged in the inner machine chamber 11, and the outer machine 20 is arranged in the outer machine chamber 12. The inner machine 10 and the outer machine 20 cooperate to cool the inner machine chamber 11.

[0047] The outer machine 20 is used to heat the outer machine chamber 12 to provide a high-temperature environment for the outer machine 20 itself, and the inner machine 10 and the outer machine 20 cooperate to test the equipment.

[0048] According to the above technical solution, in the air conditioner test equipment provided by the present disclosure, when the inner machine 10 and the outer machine 20 cooperate to cool, that is, the inner machine 10 and the outer machine 20 can transfer heat from the inner machine chamber 11 to the outer machine chamber 12, that is, the inner machine 10 can reduce the temperature of the inner machine chamber 11, and the outer machine 20 can increase the temperature of the outer machine chamber 12. Therefore, the outer machine 20 can heat the outer machine chamber 12 to provide a high-temperature environment for the outer machine 20 itself. In this way, by transferring heat from the inner machine chamber 11 to the outer machine chamber 12, the outer machine 20 can be provided with a high-temperature environment by using the heat of the outer machine chamber 12 and the inner machine chamber 11 themselves, so as to test the outer machine 20 under high temperature, thereby reducing or even avoiding the energy consumption caused by heating the outer machine chamber 12 by using an external air conditioning system. Here, the heat of the inner machine chamber 11 and the outer machine chamber 12 themselves can be understood as at least including the internal energy stored in the air in each of them. In addition, the inner machine 10 and the outer machine 20 are tested as a whole as the tested equipment. The air conditioner test equipment can test the tested equipment under high temperature to test the reliability of the tested equipment under high temperature and long-term operation, thereby shortening the factory test time of the tested equipment.

[0049] In some embodiments, referring to Figure 1 As shown in FIG. 1, the inner machine chamber 11 and the outer machine chamber 12 can be provided with a heat transfer channel 2 therebetween, which is used for mutual heat transfer between the two or heat transfer from one to the other. In this way, by using the heat transfer channel 2, mutual heat transfer between the inner machine chamber 11 and the outer machine chamber 12 or heat transfer from one to the other can be achieved. In this way, the temperature of any one of the inner machine chamber 11 and the outer machine chamber 12 can be balanced, which is conducive to avoiding excessively high or low temperature of the inner machine chamber 11 or avoiding excessively high temperature of the outer machine chamber 12, thereby facilitating long-term testing of the outer machine 20 and improving the reliability of the air conditioner test equipment.

[0050] It should be noted that the heat transfer channel 2 is used for heat transfer from one to the other between the inner machine chamber 11 and the outer machine chamber 12, which can be understood as that the inner machine chamber 11 transfers heat to the outer machine chamber 12 through the heat transfer channel 2, or the outer machine chamber 12 transfers heat to the inner machine chamber 11 through the heat transfer channel 2.

[0051] In some embodiments, the heat transfer passage can be provided with a heat transfer control structure to enable the inner chamber and / or the outer chamber to be in a corresponding experimental temperature range. Here, since the heat transfer passage is provided with the heat transfer control structure, the heat transfer control structure can control the inner chamber 11 to transfer an appropriate amount of heat to the outer chamber 12, or control the outer chamber 12 to transfer an appropriate amount of heat to the inner chamber 11. The temperature of any one of the inner chamber 11 and the outer chamber 12 can be balanced, which helps to avoid the temperature of the inner chamber 11 being too high or too low, or the temperature of the outer chamber 12 being too low or too high, i.e. the heat transfer control structure provided by the heat transfer passage can enable the inner chamber and / or the outer chamber to be in a corresponding experimental temperature range.

[0052] Next, the structure of the heat transfer passage 2 will be described in detail to explain how the heat transfer control structure enables the inner chamber and / or the outer chamber to be in a corresponding experimental temperature range.

[0053] In some embodiments of the present disclosure, with reference to Figure 1 As shown in FIG. 1, the heat transfer passage 2 can include an air flow channel 21 for connecting the inner chamber 11 and the outer chamber 12. In this way, the air flow channel 21 can enable the mutual flow of air between the inner chamber 11 and the outer chamber 12, or enable the flow of air from one to the other, whereby heat transfer can be achieved by the flow of air, and the flow of air can improve the efficiency of heat transfer. Of course, in other embodiments, the heat transfer passage 2 can also include a heat exchange medium, which can be made of a medium with a good thermal conductivity, whereby rapid heat transfer can also be achieved. In addition, the heat exchange medium can have a one-way heat conduction function, or be provided in a structure with a one-way heat conduction function to achieve one-way heat conduction, which is not limited by the present disclosure. As described above, the air flow channel 21 or the heat exchange medium are both feasible embodiments of the heat transfer control structure, and can enable the inner chamber and / or the outer chamber to be in a corresponding experimental temperature range.

[0054] In some embodiments of the present disclosure, with reference to Figure 1As shown in FIG. 1, the air flow channel 21 can include a first air flow channel 211 for flowing air in the inner machine chamber 11 into the outer machine chamber 12, so that when the inner machine 10 and the outer machine 20 cooperate to cool, and when the air in the inner machine chamber 11 flows into the outer machine chamber 12, this can reduce the temperature of the outer machine chamber 12, avoiding the temperature of the outer machine chamber 12 being too high; and a second air flow channel 212 for flowing air in the outer machine chamber 12 into the inner machine chamber 11, so that when the inner machine 10 and the outer machine 20 cooperate to cool, and when the air in the outer machine chamber 12 flows into the inner machine chamber 11, this can increase the temperature of the inner machine chamber 11, avoiding the temperature of the inner machine chamber 11 being too low. Of course, when the air flow channel 21 is in communication with the inner machine chamber 11 and the outer machine chamber 12, it can also only include the first air flow channel 211 or the second air flow channel 212.

[0055] In some embodiments, the first air flow channel 211 and the second air flow channel 212 are used as one-way flow channels.

[0056] In some embodiments, in the embodiment in which the air flow channel 21 includes the first air flow channel 211 and the second air flow channel 212, with reference to Figure 1 As shown in FIG. 1, when the inner machine 10 and the outer machine 20 cooperate to cool the inner machine chamber, the first air flow channel 211 can be adjacent to the bottom of the experimental equipment, and the second air flow channel 212 can be adjacent to the top of the experimental equipment. Here, since the second air flow channel 212 introduces hotter air into cooler air, based on the characteristic that high-temperature gas will float upwards, the second air flow channel 212 is arranged upwards, which is beneficial for introducing hotter air into cooler air. Similarly, based on the characteristic that low-temperature gas will sink, the first air flow channel 211 is arranged downwards, which is beneficial for the first air flow channel 211 to introduce cooler air into hotter air.

[0057] Of course, in other embodiments, the first air flow channel 211 and the second air flow channel 212 can both be adjacent to the top of the experimental equipment. In this way, the higher position can avoid other components blocking the first air flow channel 211 and the second air flow channel 212, and can achieve centralized arrangement of the first air flow channel 211 and the second air flow channel 212.

[0058] In some embodiments of the present disclosure, with reference to Figure 1As shown in FIG. 1, the air flow channel 21 can be provided with a blocking adjustment member 3, and the heat transfer control structure can include the blocking adjustment member 3 for opening or closing the air flow channel 21 or adjusting the opening degree of the air flow channel 21 when the air flows through. In this way, when heat exchange is needed to be performed by using the air flow channel 21, the blocking adjustment member 3 can be used to open the air flow channel 21, and the opening degree of the air flow channel 21 can be adjusted to adjust the heat exchange efficiency, and the heat exchange efficiency can be increased by increasing the opening degree of the air flow channel 21 and decreased by decreasing the opening degree of the air flow channel 21, so that the heat exchange efficiency can be flexibly adjusted. Correspondingly, when heat exchange by using air is needed to be stopped, the air flow channel 21 can be closed, so that the reliability of the air use experimental device can be improved. Here, the heat transfer control structure can control the opening and closing of the blocking adjustment member and the adjustment of the opening degree to control the heat transfer and the transfer efficiency.

[0059] In some embodiments of the present disclosure, reference is made to Figure 1 and Figure 3 to Figure 5 As shown in FIG. 1, the blocking adjustment member 3 can be rotationally connected to the air flow channel 21, that is, the blocking adjustment member 3 can be used to open or close the air flow channel 21 by rotation, and the air flow channel 21 can be connected with a stop structure 4, and the blocking adjustment member 3 and the stop structure 4 are separably overlapped, wherein when the blocking adjustment member 3 is separated from the stop structure 4 or spaced, the blocking adjustment member 3 is in an open position for opening the air flow channel 21, and when the blocking adjustment member 3 is overlapped with the stop structure 4, the blocking adjustment member 3 is in a closed position for closing the air flow channel 21, and at this time, since the blocking adjustment member 3 is overlapped with the stop structure 4, the stop structure 4 can limit the blocking adjustment member 3 from rotating in the opposite direction to open the air flow channel 21, so that the self-locking of the blocking adjustment member 3 can be achieved. When at least one of the first air flow channel 211 and the second air flow channel 212 is provided with the blocking adjustment member 3 and the stop structure 4, the first air flow channel 211 and the second air flow channel 212 can be ensured to be used as one-way flow channels.

[0060] It should be noted that when the blocking adjustment member 3 rotates clockwise to open the air flow channel 21, the opposite direction mentioned above refers to counterclockwise rotation. When the blocking adjustment member 3 rotates counterclockwise to open the air flow channel 21, the opposite direction mentioned above refers to clockwise rotation.

[0061] In some embodiments of the present disclosure, reference is made to Figure 1 and Figure 3 to Figure 7As shown in FIG. 1, the blocking adjustment member 3 can include a plurality of separable overlapping blocking adjustment plates 31, and each of the plurality of blocking adjustment plates 31 is rotationally connected with the air flow channel 21, so that when the plurality of blocking adjustment plates 31 simultaneously open the air flow channel 21, the flow area of the air flow channel 21 can be increased. Among them, the innermost blocking adjustment plate 31 and the stop structure 4 are separably overlapped, so that when the plurality of blocking adjustment plates 31 close the air flow channel 21, the plurality of blocking adjustment plates 31 are overlapped together, and the innermost blocking adjustment plate 31 is overlapped with the stop structure 4. At this time, such a design can prevent the plurality of blocking adjustment plates 31 from rotating in the opposite direction to open the air flow channel 21.

[0062] It should be noted that the innermost blocking adjustment plate 31 can be understood as the blocking adjustment plate 31 that opens or closes the air flow channel 21 last among the plurality of blocking adjustment plates 31.

[0063] In some embodiments, referring to Figure 4 As shown in FIG. 1, the stop structure 4 can be configured as a stop protrusion. Of course, referring to Figure 6 As shown in FIG. 1, the stop structure 4 can also be configured as a protruding portion protruding from the air flow channel 21, and the present disclosure does not make too many limitations on this.

[0064] In some embodiments of the present disclosure, referring to Figure 1 and Figure 7 As shown in FIG. 1, a rotation reset structure 5 can be connected between the blocking adjustment member 3 and the air flow channel 21, and the rotation reset structure 5 is used to reset the blocking adjustment member 3 to close the air flow channel 21. That is, when the blocking adjustment member 3 opens the air flow channel 21, the rotation reset structure 5 can store a reset force, and when it is needed to close the air flow channel 21, the rotation reset structure 5 can reset the blocking adjustment member 3 to close the air flow channel 21 through the reset force, so that the reliable closing of the air flow channel 21 by the blocking adjustment member 3 can be realized.

[0065] In some embodiments, referring to Figure 7 As shown in FIG. 1, the rotation reset structure 5 can be configured as a rotation shaft, and the rotation axis of the rotation shaft extends in the horizontal direction and is located above the center of gravity of the blocking adjustment member 3, so that when the blocking adjustment member 3 opens the air flow channel 21, part of the gravity of the blocking adjustment member 3 can be converted into the reset force through the rotation shaft, thereby facilitating the automatic reset of the blocking adjustment member 3 by the rotation shaft cooperating with the gravity of the blocking adjustment member 3.

[0066] In some embodiments, the rotating reset structure 5 can also be configured as an elastic reset structure, which can have an elastic force to drive the blocking adjustment member 3 to close the air flow channel 21, that is, when the blocking adjustment member 3 opens the air flow channel 21, the elastic reset structure can store the elastic force to achieve automatic reset of the blocking adjustment member 3. In this case, the elastic reset structure can be configured as a torsion spring to adapt to the rotation of the blocking adjustment member 3. Of course, the elastic reset structure can also be configured as a tension spring.

[0067] In some embodiments of the present disclosure, referring to Figure 1 In some embodiments of the present disclosure, referring to

[0068] In some embodiments of the present disclosure, referring to Figure 1 In some embodiments of the present disclosure, referring to

[0069] In some embodiments of the present disclosure, referring to Figure 1As shown in FIG. 1, at least one of the first air flow channel 211 and the second air flow channel 212 is provided with a fan 6 for powering air flow. Rotation of the fan 6 can drive air flow, thereby improving reliability of heat exchange. In some embodiments, the first air flow channel 211 can be provided with the fan 6, and the second air flow channel 212 can be provided without the fan 6, or the second air flow channel 212 can be provided with the fan 6, and the first air flow channel 211 can be provided without the fan 6, or both the first air flow channel 211 and the second air flow channel 212 can be provided with the fan 6.

[0070] Next, the disclosure will introduce the specific use process of the air flow channel 21 in combination with the above specific embodiments. Referring to FIG. 1, Figure 1 to Figure 7 As shown in FIG. 1, when the inner machine 10 and the outer machine 20 cooperate to refrigerate, and when mutual heat exchange between the inner machine chamber 11 and the outer machine chamber 12 is required, the fan 6 in the second air flow channel 212 is started, the fan 6 pushes the plurality of blocking adjustment plates 31 in the second air flow channel 212 to open, so that the air in the outer machine chamber 12 flows into the inner machine chamber 11, and then the air in the inner machine chamber 11 becomes positive pressure, and the positive pressure air pushes the plurality of blocking adjustment plates 31 in the first air flow channel 211 to open, so that the air in the inner machine chamber 11 flows into the outer machine chamber 12, at this time, mutual heat exchange between the inner machine chamber 11 and the outer machine chamber 12 can be achieved, in addition, since the air in the inner machine chamber 11 enters the outer machine chamber 12, and the air in the outer machine chamber 12 enters the inner machine chamber 11, the above-mentioned arrangement can also achieve air pressure balance of the inner machine chamber 11 and air pressure balance of the outer machine chamber 12. When it is required to stop the mutual heat exchange between the inner machine chamber 11 and the outer machine chamber 12, the fan 6 is stopped, at this time, the rotating shaft can convert the gravity of the blocking adjustment plate 31 into a reset force, so that the plurality of blocking adjustment plates 31 are automatically reset to close the first air flow channel 211 or the second air flow channel 212, and then the arrangement of the stop structure 4 can achieve self-locking of the blocking adjustment plate 31.

[0071] In some embodiments of the disclosure, referring to FIG. 1, Figure 1 As shown in FIG. 1, the experimental equipment can also be provided with an external heat exchange channel 7 for heat exchange between the experimental equipment and the external environment, so that heat exchange between the experimental equipment and the external environment can facilitate adjustment of the temperature of the inner machine chamber 11 or the outer machine chamber 12 in the experimental equipment.

[0072] In some embodiments, referring to FIG. 1, Figure 1As shown in FIG. 1, the external heat exchange passage 7 can include an external air inlet passage 71 and an external air outlet passage 72. The external air inlet passage 71 is configured to allow air outside the experimental apparatus to enter the experimental apparatus, for example, to enter the inner machine chamber 11 or the outer machine chamber 12 of the experimental apparatus. The external air outlet passage 72 is configured to allow air inside the experimental apparatus to flow out to the outside of the experimental apparatus, for example, to flow out of the inner machine chamber 11 or the outer machine chamber 12 of the experimental apparatus. Thus, by using the heat exchange between the experimental apparatus and the external air, the temperature of the inner machine chamber 11 can be prevented from being too high or too low, or the temperature of the outer machine chamber 12 can be prevented from being too low or too high. In addition, the arrangement of the external air inlet passage 71 and the external air outlet passage 72 can also ensure the air pressure balance of the experimental apparatus and prevent air pressure fluctuation. In some other embodiments, the external heat exchange passage 7 can only include the external air inlet passage 71, which is configured to allow air outside the experimental apparatus to enter the experimental apparatus. In this way, the external air and the air inside the experimental apparatus are mixed to achieve the effect of adjusting the temperature inside the experimental apparatus.

[0073] In some embodiments of the present disclosure, with reference to Figure 1 As shown in FIG. 1, the external air inlet passage 71 can be in communication with one of the inner machine chamber 11 and the outer machine chamber 12, and the external air outlet passage 72 can be in communication with one of the inner machine chamber 11 and the outer machine chamber 12. In this way, when it is necessary to lower or raise the temperature of the inner machine chamber 11, the external air inlet passage 71 can be in communication with the inner machine chamber 11, and at this time, the external air outlet passage 72 can be in communication with either of the inner machine chamber 11 and the outer machine chamber 12. Similarly, when it is necessary to raise or lower the temperature of the outer machine chamber 12, the external air inlet passage 71 can be in communication with the outer machine chamber 12, and the external air outlet passage 72 can be in communication with either of the inner machine chamber 11 and the outer machine chamber 12. In some embodiments, a damper can be arranged at the external air inlet passage 71, and the damper is configured to open or close the external air inlet passage 71. In this way, the external air inlet passage 71 can be flexibly opened or closed. The opening and closing principle of the damper is well known to those skilled in the art, and will not be described here in detail.

[0074] In some embodiments, with reference to Figure 1 As shown in FIG. 1, the external air inlet passage 71 and the external air outlet passage 72 can both be in communication with the outer machine chamber 12. In this way, the heat exchange between the outer machine chamber 12 and the external air, for example, the external atmosphere, can be quickly achieved to quickly raise or lower the temperature of the outer machine chamber 12.

[0075] In some embodiments, with reference to Figure 1As shown in FIG. 1, the external air inlet passage 71 is adjacent to the bottom of the outer machine chamber 12, and the external air outlet passage 72 is adjacent to the top of the outer machine chamber 12. Here, when the inner machine 10 and the outer machine 20 cooperate to refrigerate, the temperature of the outer machine chamber 12 is usually higher than the temperature of the external atmosphere, so the external air inlet passage 71 is arranged lower to facilitate the automatic entry of cooler external air into the outer machine chamber 12, and the external air outlet passage 72 is arranged higher to facilitate the automatic discharge of the hotter air in the outer machine chamber 12 to the outside, such as the external atmosphere.

[0076] Optionally, as shown in FIG. 1, the inner machine 10 can be connected with a first air flow passage 211, and the outer machine 20 can be connected with a second air flow passage 212. The first air flow passage 211 and the second air flow passage 212 can be connected with the heat transfer passage 2, and the heat transfer passage 2 can be connected with the inner machine chamber 11 and the outer machine chamber 12. Figure 1 As shown in FIG. 1, the external air outlet passage 72 can be connected with a fan 6, and the fan 6 is used to send the air in the outer machine chamber 12 to the outside of the experimental equipment.
