It can be understood that the present embodiment provides a new air supply manner: the air outlet 4 is arranged on one side of the test chamber 2, and the air return inlet 5 is arranged on the other corresponding side of the test chamber 2. The air flow direction in the test from the air-conditioning room 3 was: flows in from the air outlet 4 on one side of the test chamber 2, flows through the test chamber 2, flows out from the air return opening 5 on the other side of the test chamber 2, enters the air conditioning chamber 3, and circulates in this way. The position of air outlet 4 can set up the optional position in 2 air-out one sides in laboratory, so all can directly send into the air after the regulation to every corner of 2 laboratories to promote the homogeneity of 2 temperatures in laboratory.
In the temperature simulation test chamber of the present embodiment, the air conditioning chamber 3 of the cutaway-edge-type may be a cutaway-edge-type in front view, that is, the direction of air flow is the left side, the middle top, and the right side of the temperature simulation test chamber. In other embodiments, the test chamber may be a notched shape in plan view, i.e., the air flow direction is from the left, middle, and right sides of the temperature simulation test chamber.

Further, a heater 36 is provided in the upper air-conditioning chamber 32 for heating the air flowing through the upper air-conditioning chamber 32. In the air-conditioning room 3, the air returned from the laboratory 2 is sent to the heater 36 through the evaporator 34 and then the blower body 35. The arrangement of the evaporator 34 above the return air guide 22 and the heater 36 in the upper air-conditioning compartment 3 ensures that the upper part of the return air guide 22 has as far upward an opening for return air as possible, thereby ensuring temperature uniformity at each location in the laboratory 2.
Specifically, the fan body 35 of air supply is located 34 upper portions of evaporimeter and is close to evaporimeter 34, and compares far away apart from the air-out end of air conditioning room 3, can guarantee that the air flow rate that gets into in laboratory 2 is relatively slow, is favorable to guaranteeing the uniformity of the temperature of test sample windward side and leeward side in laboratory 2.

In order to make the air in the air-conditioning compartment 3 better flow through the heater 36, two symmetrical first air deflectors 37 are provided at the inflow end of the air flowing through the heater 36. Preferably, the first wind guard 37 is inclined at 30 to 60 degrees with respect to the air flowing direction so that the air can flow more smoothly and entirely through the heater 36 so that the air flowing therethrough is better heated.
Further, as shown in fig. 6, a second wind deflector 38 is provided at a corner of the connection between the upper air-conditioning compartment 32 and the left air-conditioning compartment 31, and one end of the second wind deflector 38 is connected to the upper side wall of the upper air-conditioning compartment 32 in an inclined manner and the other end is connected to the left side wall of the left air-conditioning compartment 31 in an inclined manner. In order to make the air in the air-conditioning room 3 flow better through the corners of the air-conditioning room 3, a second wind deflector 38 is provided at the corners of the air-conditioning room 3. Preferably, the second wind deflector 38 is inclined at 45 degrees with respect to the air flow direction.
For example, in some application scenarios, the second wind deflector 38 has a circular arc structure, which facilitates optimizing the air flow and reducing the flow resistance.
In other application scenarios, the second wind deflector 38 is a flat plate structure, which not only satisfies the function of air diversion, but also facilitates manufacturing and reduces production cost.

Through the arrangement of 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 (that is, the holes of the honeycomb holes penetrate through the plate surface of the honeycomb plate 7 in the thickness direction of the honeycomb plate 7), so that the air blown out by the air outlet air guide plate 21 can be sent out in the horizontal direction, and the temperature uniformity of the left position and the right position in the laboratory 2 is improved.
Because the test sample can generate heat when being carried, for the homogeneity of temperature in whole laboratory 2, need make the test sample position obtain enough big amount of wind, so only set up air outlet 4 in the position that air-out aviation baffle 21 corresponds the test sample, air outlet 4 corresponds with the mounted position of test sample, the number of piles of 4 air outlets and the test sample of air-out aviation baffle 21 of proof box are put the number of piles one-to-one.

For example, in order to achieve the same temperature uniformity of the test samples arranged in the same layer and 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 and air guide plate 21 are uniformly distributed along the front and rear direction.
Further, as shown in fig. 5, the total area of each layer of the outlet 4 of the outlet air deflector 21 gradually increases from top to bottom. It can be understood that, in order to make the test samples placed on the upper, middle and lower layers obtain the same air volume, so as to maintain the uniformity of the temperature between the upper, middle and lower layers of the test box, the total area of each layer of air outlets 4 of the air outlet air deflector 21 is gradually increased from the upper layer to the lower layer.
Further, be provided with the heat preservation in the outer box 1, reduce the outside conduction temperature of temperature simulation test case, guarantee the stability of whole proof box internal environment, also help reducing the energy consumption of air-conditioning room 3. Specifically, a door is provided in front of the outer case 1, and the door can be closed and opened with respect to the outer case 1.

Further, as shown in fig. 2, a plurality of harness through holes 13 are perforated in the back plate 12 of the outer case 1. After the test sample is placed in the test cavity 23 of the laboratory 2, the running condition of the test sample in the electrified working state needs to be simulated, and one end of the lead is electrically connected with the test sample through the wire harness through hole 13. The wiring harness through hole 13 is tightly attached to the lead, so that the influence of the external temperature on the temperature of the laboratory 2 is reduced. Specifically, the wire harness via hole 13 performs a sealed via hole of the wire harness by a circular sealing plug.
