Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In one embodiment, referring to fig. 1, a temperature impact test chamber 100, the temperature impact test chamber 100 includes: the refrigerator includes a cabinet 110, a first damper 130, a heating device 150, and a cooling device 160. The case 110 has a first chamber 111, a second chamber 112, and a third chamber 113 arranged in parallel. A partition 120 is disposed on a wall of the first chamber 111 to divide the first chamber 111 into a first partition chamber 1111 and a second partition chamber 1112. The second body cavity 1112 communicates with the second chamber 112 through the first opening 115. The box 110 is provided with a first air port 114 through which the second chamber 1112 communicates with the outside. The separator 120 is provided with a communication port 121. The first damper 130 is movably disposed in the box 110 for selectively opening the first air opening 114 and the communication opening 121. One of the heating device 150 and the cooling device 160 is located in the first compartment 1111 and the other is located in the third compartment 113. The heating device 150 is used to heat the interior of the second chamber 112. The cooling device 160 is used for cooling in the second chamber 112.

In the temperature impact test chamber 100, the heating device 150 may be disposed in the first chamber 1111 or the third chamber 113 during assembly. The heating device 150 and the cooling device 160 may be pre-activated separately before the high and low temperature impact test is performed, so that the temperature in the second chamber 112 can be raised or lowered as soon as possible, thereby achieving an effective high and low temperature impact test. Since the case 110 is provided with the first air port 114 through which the second chamber 1112 is communicated with the outside, when the ambient temperature exposure test is performed, the first damper 130 is moved to open the first air port 114 and close the communication port 121, that is, the first air port 114, the second chamber 1112 and the second chamber 112 are in a conduction state. At this time, the external air can enter through the first air port 114 and sequentially flow into the second sub-chamber 1112 and the second chamber 112, so that the climate of the second chamber 112 is kept consistent with the external environment, thereby allowing the ambient temperature exposure test to be stably performed in the second chamber 112. Thus, the temperature impact test box 100 effectively meets the requirements of the environmental temperature exposure test on the premise of meeting the high and low temperature exposure test. Meanwhile, in the test process, the structural design is simple, and only the first air door 130 needs to be moved in the operation process, so that great convenience is brought to the test.

It should be noted that the arrangement positions of the heating device 150 and the cooling device 160 can be two ways: first, the heating device 150 is disposed in the first chamber 1111, and the cooling device 160 is disposed in the third chamber 113; second, the heating device 150 is disposed in the third compartment, and the cooling device 160 is disposed in the first compartment 1111. When the heating device 150 is disposed in the first sub-chamber 1111, if the first damper 130 is closed at the communication port 121, the communication between the first sub-chamber 1111 and the second sub-chamber 1112 is blocked, and the communication between the second sub-chamber 1112 and the outside is correspondingly opened; if the first damper 130 is closed at the first air port 114, the communication between the first sub-chamber 1111 and the second sub-chamber 1112 is opened, and the communication between the second sub-chamber 1112 and the outside is blocked accordingly.

It should be noted that the heating device 150 and the cooling device 160 respectively heat and cool the second chamber 112 in various ways, such as: a damper or an additional pipe is provided between the first split chamber 1111 and the second chamber 112 and between the third chamber 113 and the second chamber 112. In addition, the first chamber 111, the second chamber 112 and the third chamber 113 are sequentially arranged in the box body 110, for example: the first chamber 111, the second chamber 112, and the third chamber 113 are arranged in parallel at intervals in the height direction, the longitudinal direction, the width direction, and the like of the case 110.

Specifically, referring to fig. 1, the first chamber 111, the second chamber 112, and the third chamber 113 are disposed in parallel at intervals along the height direction of the box body 110.

Further, referring to fig. 1, the temperature impact test chamber 100 further includes a second damper 131. The box body 110 is provided with a second air opening 1121 for communicating the second chamber 112 with the outside. The second damper 131 is movably disposed on the cavity wall of the second chamber 112 and is used to open and close the second air hole 1121, so that the second air hole 1121 is additionally disposed in the second chamber 112 to form an air circulation together with the first air hole 114, the second sub-chamber 1112 and the second chamber 112, so as to accelerate the air circulation between the inside of the second chamber 112 and the outside, and thus the second chamber 112 is rapidly consistent with the outside climate.

Alternatively, the second damper 131 opens or closes the second orifice 1121 in a manner that is not limited to rotation, translation, rotation, and the like.

Further, referring to fig. 1, the temperature impact test chamber 100 further includes a first fan 140. The first fan 140 is located within the second chamber 1112. The first fan 140 is used to drive the airflow to be sucked from the first air inlet 114 and to flow through the second body cavity 1112, the second chamber 112 and the second air inlet 1121 in sequence. Therefore, referring to fig. 2, when the environmental temperature exposure test is performed, the second damper 131 is moved to open the second air opening 1121; then, the first fan 140 is turned on to drive the outside air flow to be sucked from the first air inlet 114, and the flow in the second chamber 1112 and the second chamber 112 is accelerated, so as to achieve the dynamic balance of the indoor and outdoor climates.

In one embodiment, referring to fig. 1, the first damper 130 is rotatably disposed in the box 110. The first damper 130 is rotated to the first position to close the first air port 114. When the first damper 130 rotates to the second station, the communication port 121 can be closed. Thus, when the first damper 130 is switched back and forth between the first station and the second station, the first air port 114 and the communication port 121 can be opened alternatively, so that the second chamber 1112 can be communicated with the outside or the first chamber 1111.

In one embodiment, referring to FIG. 1, the temperature shock test chamber 100 further includes a third damper 132. The third damper 132 opens and closes the first opening 115. In this embodiment, the third damper 132 is additionally provided, so that the opening and closing of the first opening 115 can be effectively controlled, and the flow direction of the air flow in the box 110 can be controlled.

Alternatively, the third damper 132 may open or close the first opening 115 by, but not limited to, rotation, translation, rotation, and the like.

In one embodiment, referring to fig. 1, the temperature impact test chamber 100 further includes a fourth damper 133. A second opening 116 is provided between the first chamber 1111 and the second chamber 112, and the fourth damper 133 opens and closes the second opening 116. Therefore, the first opening 115 and the second opening 116 realize the circulating flow of the air flow between the first chamber 111 and the second chamber 112, so that the temperature in the second chamber 112 can quickly reach the required temperature, which is beneficial to improving the temperature test efficiency.

In one embodiment, referring to fig. 1, the temperature impact test chamber 100 further includes a fifth damper 134, at least two third openings 117 are spaced between the second chamber 112 and the third chamber 113, and the opening and closing of all the third openings 117 are controlled by at least one fifth damper 134. When the at least two third openings 117 are opened, a gas flow circulation passage is formed between the second chamber 112 and the third chamber 113. If the cooling device 160 is installed in the third chamber 113, the fifth damper 134 is moved to open the third opening 117, so that the second chamber 112 is communicated with the third chamber 113. At this time, the cold air in the third chamber 113 rapidly enters the second chamber 112, so that the temperature in the second chamber 112 reaches the preset temperature value.

The number of the fifth dampers 134 may be one or more. When the number of the fifth dampers 134 is one, all the third openings 117 are uniformly controlled by the same fifth damper 134. When the number of the fifth dampers 134 is plural, the fifth dampers 134 may be controlled in one-to-one correspondence with the third openings 117.

Specifically, referring to fig. 1, there are two third openings 117 and two fifth dampers 134, the heating device 150 is located in the first sub-chamber 1111, and the cooling device 160 is located in the third sub-chamber. At this time, in the test process, please refer to fig. 2, the preparation mode is: the first damper 130 closes the communication port 121, the second damper 131 closes the second air port 1121, the third damper 132 closes the first opening 115, the fourth damper 133 closes the second opening 116, and the fifth damper 134 closes the third opening 117. The heating device 150 now heats the first compartment 1111 and the cooling device 160 cools the third compartment 113. Referring to fig. 2, the environmental temperature exposure test is: the second damper 131 and the third damper 132 are opened, and the first fan 140 is started, so that the external air flow is sucked from the first air inlet 114 and flows through the second chamber 1112, the second chamber 112 and the second air inlet 1121 in sequence, and air flow convection is formed, so that the temperature in the second chamber 112 reaches the ambient temperature. Referring to fig. 3, the high temperature exposure test is: the first damper 130 closes the first air port 114, the fourth damper 133 is opened, and the second damper 131 is closed, so that the first chamber 1111, the second chamber 1112 and the second chamber 112 are communicated with each other, and the temperature in the second chamber 112 is guaranteed to be heated to the set temperature. Referring to fig. 4, the low temperature exposure test is: the third damper 132 and the fourth damper 133 are closed, and the fifth damper 134 is opened, so that a flow is formed between the second chamber 112 and the third chamber 113, and the temperature in the second chamber 112 is ensured to be reduced to the preset temperature. Thus, the temperature impact test box 100 has the characteristics of simple structure, low cost, flexible configuration, short test time, high test efficiency and the like.

In one embodiment, referring to fig. 1, the heating device 150 includes a second fan 151 and a first heater 152.
