The two air supply modes of horizontal air supply mode and vertical air supply mode are at the corner of the laboratory and the middle part of the air outlet return opening, and because the air is not easy to directly flow through the positions, compared with the position through which the air directly flows, the temperature difference between the two air supply modes is larger, so that the uniformity of the temperature at different positions in the laboratory is poorer.

However, for some electronic products with smaller volume, small-sized electronic products are required to be placed on each layer, and the small-sized electronic products are placed on almost every corner of a laboratory, so that samples at every corner in the laboratory are required to be subjected to a basically similar temperature environment, and at the moment, the temperature uniformity requirements for all positions in the laboratory are relatively high, so that the horizontal air inlet and the vertical air inlet in the current stage cannot effectively meet the temperature uniformity requirements.

The laboratory 2 is used for placing a test sample, which can receive simulated environmental conditions, such as temperature conditions or humidity conditions, etc., in the laboratory 2 to complete the relevant test.

The air outlets 4 of a plurality of layers are arranged on the air outlet air deflector 21 so that the test cavity 23 is communicated with the air outlet end of the air conditioning chamber 3. Several layers of air return openings 5 are arranged on the air return air deflector 22 so that the test cavity 23 is communicated with the air return end of the air conditioning chamber 3.
As shown in fig. 3 and 5, specifically, each layer of air outlets 4 is provided with a plurality of air outlet holes, and the plurality of air outlet holes of each layer of air outlets 4 are uniformly distributed on the air outlet air deflector 21.

In short, in the temperature simulation test box provided by the embodiment, the test chamber 2 is arranged on the inner bottom plate 11 of the outer box body 1, so that the air conditioning chamber 3 with a notch is formed between the outer side wall of the test chamber 2 and the inner side wall of the outer box body 1, through the arrangement mode, air needs to flow through the right air conditioning chamber 33, the upper air conditioning chamber 32 and the left air conditioning chamber 31, the air flows through the whole air conditioning chamber 3 for a longer distance, the total length of the air conditioning chamber 3 can be prolonged under the condition that an air pipeline is not required to be additionally arranged, the flowing air in the air conditioning chamber 3 can be fully mixed conveniently, and the uniformity of the air temperature in the air conditioning chamber 3 can be improved, so that the air temperature after entering the test chamber 2 can be ensured to be more uniform; the left side at laboratory 2 sets up air-out aviation baffle 21 to set up the air outlet 4 of a plurality of layers on air-out aviation baffle 21, set up return air aviation baffle 22 on the right side of laboratory 2, and set up the return air inlet 5 of a plurality of layers on return air aviation baffle 22, make one side air-out of laboratory 2, the opposite side return air can guarantee the homogeneity of the interior different position temperature of whole laboratory 2, effectively satisfies the product of different volume sizes to the requirement of temperature homogeneity.
As can be appreciated, this embodiment proposes a new air supply mode: the air outlet 4 is arranged on one side of the laboratory 2, and the air return 5 is arranged on the other side corresponding to the laboratory 2. The flow direction of air from the air conditioning chamber 3 in the test was: flows in from one side air outlet 4 of the laboratory 2, flows through the laboratory 2, then flows out from the corresponding other side air return 5 of the laboratory 2, and then enters the air conditioning chamber 3, and circulates in this way. The position of the air outlet 4 can be arranged at any position on the air outlet side of the laboratory 2, so that the regulated air can be directly fed into each corner of the laboratory 2, and the temperature uniformity of the laboratory 2 is improved.
In the temperature simulation test chamber of the present embodiment, the air-conditioning chamber 3 of the flangeless type may be a front view of the flangeless type, that is, the air flow direction is the left side, the middle top, and the right side of the temperature simulation test chamber. In other embodiments, the shape of the notch may be a top view, i.e., the direction of air flow is left, middle back, right of the temperature simulation test chamber. Both of the above schemes can lengthen the path of air flow and improve the temperature uniformity in the laboratory 2.
Further, as shown in fig. 4 and 6, the air conditioning chamber 3 includes a left air conditioning chamber 31, an upper air conditioning chamber 32 and a right air conditioning chamber 33 which are sequentially communicated, the left air conditioning chamber 31 is communicated with the air outlet 4 of the air outlet deflector 21, the right air conditioning chamber 33 is communicated with the return air inlet 5 of the return air deflector 22, an evaporator 34 is provided at the upper portion of the right air conditioning chamber 33, and a fan body 35 is provided at the connecting corner between the upper air conditioning chamber 32 and the right air conditioning chamber 33 so as to cause the air flow in the right air conditioning chamber 33 to the left air conditioning chamber 31. Further, a heater 36 is provided in the upper air conditioning chamber 32 for heating air flowing through the upper air conditioning chamber 32. In the air conditioning chamber 3, the air returned from the laboratory 2 is sent to the heater 36 through the evaporator 34 and then through the fan body 35. The evaporator 34 is positioned above the return air deflector 22 and the heater 36 is positioned in the upper air conditioning chamber 3 of the test chamber, which ensures that the upper portion of the return air deflector 22 has an opening as close as possible for return air, thereby ensuring the uniformity of the temperature at each location in the test chamber 2.
Specifically, the blower body 35 for supplying air is located at the upper part of the evaporator 34 and is close to the evaporator 34, and is relatively far from the air outlet end of the air conditioning chamber 3, so that the air flow rate entering the test chamber 2 is relatively slow, and the consistency of the temperatures of the windward side and the leeward side of the test sample in the test chamber 2 is guaranteed.
Further, as shown in fig. 4, the temperature simulation test box further includes a rotation driving mechanism 6, the rotation driving mechanism 6 is disposed on the outer box 1, and an output shaft of the rotation driving mechanism 6 is in transmission connection with a rotating shaft of the fan body 35. In this embodiment, the rotary driving mechanism 6 is a motor, and the motor drives the fan body 35 to form a circulating fan together, so as to circulate the air in the air conditioning chamber 3 and the laboratory 2.
Further, as shown in fig. 7, the upper air conditioning chamber 32 further includes two first wind deflectors 37, and the two first wind deflectors 37 form a V-shaped flow guiding channel, a small opening end of the V-shaped flow guiding channel faces the heater 36, and a large opening end of the V-shaped flow guiding channel faces the fan body 35. In order to make the air in the air-conditioning chamber 3 better flow through the heater 36, two symmetrical first wind deflectors 37 are provided at the inflow end of the air flowing through the heater 36. Preferably, the first wind deflector 37 is inclined at 30-60 degrees with respect to the air flow direction so that air can more smoothly and entirely flow through the heater 36 so that the air flowing therethrough is heated better.
Further, as shown in fig. 6, a second wind deflector 38 is provided at a connecting corner between the upper air conditioning chamber 32 and the left air conditioning chamber 31, one end of the second wind deflector 38 is connected to an upper side wall of the upper air conditioning chamber 32 in an inclined manner, and the other end is connected to a left side wall of the left air conditioning chamber 31 in an inclined manner. In order to allow the air in the air-conditioning chamber 3 to flow better through the corners of the air-conditioning chamber 3, a second wind deflector 38 is provided at the corners of the air-conditioning chamber 3. Preferably, the second wind deflector 38 is inclined 45 degrees with respect to the air flow direction.
Illustratively, in some application scenarios, the second wind deflector 38 is in a circular arc configuration, which facilitates optimizing the flow of air and reducing the flow resistance.
Illustratively, in other applications, the second wind deflector 38 is in a flat plate-shaped structure, which not only satisfies the air guiding function, but also facilitates manufacturing and reduces production costs.
As shown in fig. 1 and 4, the temperature simulation test box further comprises a honeycomb plate 7, the honeycomb plate 7 is arranged on one side of the air outlet air deflector 21 facing the return air deflector 22, and a plurality of honeycomb holes are uniformly arranged on the honeycomb plate 7 at intervals. By arranging a plurality of honeycomb holes which are uniformly distributed, the air blown out by the air outlet air deflector 21 can be further homogenized, and the temperature uniformity of different positions in the laboratory 2 is improved. Specifically, the holes of the honeycomb plate 7 are perpendicular to the plate surface of the honeycomb plate 7 (i.e., the holes of the honeycomb holes penetrate through the plate surface of the honeycomb plate 7 along the thickness direction of the honeycomb plate 7), so that the air blown out by the air-out air deflector 21 can be sent out in the horizontal direction, and the temperature uniformity of the left side position and the right side position in the laboratory 2 is improved.
Because the test sample is loaded and heated, the position of the test sample needs to be provided with enough air quantity for the uniformity of the temperature in the whole test chamber 2, the air outlet 4 is arranged at the position of the air outlet air deflector 21 corresponding to the test sample, the air outlet 4 corresponds to the placing position of the test sample, and the number of layers of the air outlet 4 of the air outlet air deflector 21 of the test chamber corresponds to the number of layers of the test sample.
Illustratively, in some application scenarios, four layers of racks are arranged from top to bottom in the laboratory 2, and each layer is provided with a test sample, four layers of air outlets 4 are sequentially arranged at intervals from top to bottom in the air outlet air deflector 21, four layers of air return inlets 5 are sequentially arranged at intervals from top to bottom in the air return air deflector 22, and the four layers of air outlets 4, the test samples on the four layers of racks and the four layers of air return inlets 5 are arranged in a one-to-one correspondence along the horizontal direction.
For example, in order to obtain uniform temperature of the test samples placed on the same layer at different positions in the front and rear of the laboratory 2, the same air volume needs to be obtained, and the air outlets 4 of each layer of the air outlet air deflector 21 are uniformly distributed along the front and rear direction.
Further, as shown in fig. 5, the total area of the air outlets 4 of each layer of the air outlet deflector 21 gradually increases from top to bottom. It can be understood that, in order to obtain the same air quantity of the test samples placed on the upper, middle and lower layers, the total area of the air outlets 4 of each layer of the air outlet air deflector 21 is gradually increased from the upper layer to the lower layer, so as to maintain the temperature uniformity between the upper, middle and lower layers of the test box.
Further, the heat preservation layer is arranged in the outer box body 1, so that the outward conduction temperature of the temperature simulation test box is reduced, the stability of the environment in the whole test box is ensured, and the energy consumption of the air conditioning chamber 3 is reduced. Specifically, a door is provided in front of the outer casing 1, and the door can be closed and opened with respect to the outer casing 1. A temperature sensor is provided in the test chamber 23 of the laboratory 2 for detecting the temperature in the test chamber 23 in real time.
Further, as shown in fig. 2, a plurality of harness vias 13 are formed through the back plate 12 of the outer case 1. When the test specimen is placed in the test chamber 23 of the test chamber 2, it is necessary to simulate the operation of the test specimen in an electrified operating state, and one end of the wire is electrically connected to the test specimen through the wire harness via hole 13. The wire harness through holes 13 are tightly attached to the wires, so that the influence of the external temperature on the temperature of the laboratory 2 is reduced. Specifically, the harness via hole 13 performs sealing via hole of the harness by a circular sealing plug.
