With this setting, it can be avoided that the high-temperature and high-humidity gas is discharged into the environment, resulting in an increase in the temperature and humidity of the environment, improving the environmental protection of the use of the temperature and humidity test chamber.

It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model are shown in the drawings, rather than all the structures.

They are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] This embodiment provides a humidifying system for a temperature and humidity test chamber. Its humidifying pipe has a simple structure, is easy to process, reduces the material and labor costs of the humidifying pipe, and can condense and recycle the high-temperature and high-humidity gas discharged from the pressure relief port of the temperature and humidity test chamber, avoiding the increase in the temperature and humidity of the environment caused by the discharge of the high-temperature and high-humidity gas into the environment, and improving the environmental protection of the use of the temperature and humidity test chamber.

[0040] Specifically, as Figures 1-3 shown, the humidifying system for the temperature and humidity test chamber includes a humidifying device 100, a humidifying pipe 200, a spoiler air drum 300, a pressure relief pipeline 400 and an air heat exchanger 500.

[0041] The humidifying device 100 is arranged outside the box 10 of the temperature and humidity test box, and is used to make steam. The humidifying device 100 is provided with a steam outlet. The humidifying device 100 generally heats water to form steam, and discharges the steam through the steam outlet. The humidifying tube 200 is arranged in the box 10, and the steam inlet 210 of the humidifying tube 200 is connected to the steam outlet. Along the length direction of the humidifying tube 200, a plurality of steam exhaust ports 220 are arranged at intervals at the top of the humidifying tube 200. The steam discharged from the humidifying device 100 enters the humidifying tube 200 through the steam inlet 210 of the humidifying tube 200, and is discharged from the humidifying tube 200 through the steam exhaust port 220 of the humidifying tube 200. The steam discharged from the steam exhaust port 220 of the humidifying tube 200 is used to increase the humidity in the box 10. The turbulent air drum 300 is arranged in the housing 10 and is located above the humidifying tube 200. The turbulent air drum 300 is used to turbulent the steam discharged from the exhaust port 220, so that the humidity in the housing 10 is more uniform. The inlet of the pressure relief pipeline 400 is connected to the pressure relief port 11 of the housing 10. An air heat exchanger 500 is arranged at the outlet of the pressure relief pipeline 400. The air heat exchanger 500 is used to condense the high-temperature and high-humidity gas discharged from the outlet of the pressure relief pipeline 400. The pressure relief pipeline 400 is provided with a first drain port 411, and the condensed high-temperature and high-humidity gas is discharged from the first drain port 411.

[0042] The humidification system for the temperature and humidity test chamber provided in this embodiment directly opens a steam exhaust port 220 for exhausting steam at the top of the humidification tube 200. Compared with the prior art in which the steam exhaust port 220 is formed by welding a bend pipe, the setting of the bend pipe is omitted, the processing procedure of the humidification tube 200 is simplified, and the processing difficulty and production cost of the humidification tube 200 are reduced. In addition, by providing a turbulent wind drum 300, the steam can be disturbed and stirred, so that the steam can flow to various places in the box body 10, thereby improving the uniformity of the humidity in the box body 10. Through the cooperation of the pressure relief pipeline 400 and the air heat exchanger 500, it is possible to avoid the high-temperature and high-humidity gas from being discharged into the environment, resulting in an increase in the temperature and humidity of the environment, thereby improving the environmental friendliness of the use of the temperature and humidity test chamber. When the temperature and humidity test chamber is used indoors, it is also possible to avoid false alarms of the temperature and humidity test chamber, thereby improving the working reliability of the temperature and humidity test chamber.

[0043] Further, see Figure 2, in the length direction of the humidifying pipe 200, along the direction away from the steam inlet 210 of the humidifying pipe 200, the area of the steam outlet 220 gradually increases. After the steam enters from the steam inlet 210 of the humidifying pipe 200, a part of it will flow in the humidifying pipe 200 along the length direction of the humidifying pipe 200, and a part of it will be directly discharged from the steam outlet 220 at the top of the humidifying pipe 200. Therefore, the farther away from the steam inlet 210 of the humidifying pipe 200, the smaller the amount of steam in the humidifying pipe 200 and the slower the flow rate. By setting the area of the steam outlet 220 farther away from the steam inlet 210 of the humidifying pipe 200 to be larger and larger, it can make the amount of steam discharged from each steam outlet 220 not differ much, improving the humidifying uniformity of the humidifying pipe 200 and also improving the humidifying efficiency of the humidifying pipe 200 to a certain extent.

[0044] Further, continue to refer to Figure 2 and Figure 3 , an installation flange 230 is provided at the steam inlet 210 of the humidifying pipe 200, and a humidifying pipe bracket (not shown in the figure) is provided on the inner wall of the box body 10. The humidifying pipe 200 is installed on the humidifying pipe bracket through the installation flange 230. Fixing the humidifying pipe 200 through the installation flange 230 and the humidifying pipe bracket facilitates the installation and disassembly of the humidifying pipe 200.

[0045] Further, continue to refer to Figure 1 and Figure 3 , along the length direction of the humidifying pipe 200, a plurality of second drain ports 240 are provided at intervals at the bottom of the humidifying pipe 200. Inside the box body 10, a first water receiving tray 600 is provided below the second drain port 240, and the first water receiving tray 600 is used to collect the condensed water discharged from the second drain port 240. By providing the second drain port 240 to discharge the condensed water in the humidifying pipe 200, it can avoid the accumulated water in the humidifying pipe 200 affecting the humidifying efficiency of the humidifying pipe 200. And, by using the first water receiving tray 600 to collect the condensed water discharged from the humidifying pipe 200, it can avoid the condensed water directly dripping to the bottom of the box body 10 and affecting the environment inside the box.

[0046] Further, continue to refer to Figure 1 , the temperature and humidity test chamber further includes a spray humidifying device 700. The spray humidifying device 700 is arranged below the turbulent flow air drum 300 and is used to spray atomized water. The turbulent flow air drum 300 is used to disturb the atomized water sprayed by the spray humidifying device 700 so that the atomized water can uniformly humidify the environment inside the box body 10.

[0047] Specifically, when the humidification by only the humidifying pipe 200 is difficult to meet the needs of the test samples inside the box body 10, the spray humidifying device 700 can be started to assist the humidifying pipe 200 in humidification to improve the humidifying efficiency.

[0048] Optionally, the steam outlet and the steam inlet 210 of the humidifying pipe 200 can be connected through a high-temperature resistant hose. Compared with using a copper pipe for connection, on the one hand, the material cost is reduced; on the other hand, the high-temperature resistant hose can be bent arbitrarily and is suitable for various installation environments; furthermore, it can be directly fixed with a hose clamp, making installation and disassembly more convenient.

[0049] It should be noted that since the steam temperature is relatively high, a high-temperature resistant hose is selected to ensure the reliability of the connection between the humidifying device 100 and the humidifying pipe 200.

[0050] Furthermore, a heat insulation layer is wrapped outside the high-temperature resistant hose. By setting the heat insulation layer, the heat exchange efficiency between the steam and the outside air during the steam transportation process can be reduced, thereby reducing the risk of the steam being condensed into water. As a result, with the power of the humidifying device 100 remaining unchanged, more steam is used to humidify the environment inside the box, reducing the energy consumption to a certain extent and improving the humidifying efficiency.

[0051] Furthermore, continue to refer to Figure 1 , a return air plate 900 is further provided inside the box body 10. The return air plate 900 divides the box body 10 into a test space and a fitting space. The test space is used to place test samples, and the fitting space is used to place fittings such as the turbulent flow air drum 300, the spray humidifying device 700, and the humidifying pipe 200. An air outlet (not shown in the figure) is provided above the return air plate 900. The air outlet is disposed opposite to the turbulent flow air drum 300. The turbulent flow air drum 300 sends the humid air into the test space through the air outlet. A return air port (not shown in the figure) is provided below the return air plate 900. The air in the test space enters the fitting space through the return air port, forming an air circulation.

[0052] Furthermore, the first drain port 411 can be arranged at the lowest position in the height direction of the pressure relief pipeline 400. With such an arrangement, the condensed water in the pressure relief pipeline 400 can be fully converged to the first drain port 411 and discharged through the first drain port 411, avoiding the accumulation of condensed water in the pressure relief pipeline 400.

[0053] Optionally, continue to refer to Figure 1 , in this embodiment, the pressure relief pipeline 400 is in an L shape, including a horizontal section 410 and a vertical section 420 extending upward in the vertical direction. The opening of the horizontal section 410 is connected to the pressure relief port 11, and the opening of the vertical section 420 is disposed opposite to the air heat exchanger 500. The drain port is arranged at the bottom of the horizontal section 410. Since the high-temperature and high-humidity gas discharged from the pressure relief port 11 is lighter and will move upward, the vertical section 420 is provided to better guide the movement of the high-temperature and high-humidity gas.

[0054] Further, in a possible embodiment, a second water receiving tray 800 is provided below the first drain outlet 411. The second water receiving tray 800 is used to store the condensed water discharged from the first drain outlet 411, preventing the condensed water from being randomly discharged and polluting the environment. In another possible embodiment, the humidification system for the temperature and humidity test chamber further includes a drain pipe (not shown in the figure). The inlet of the drain pipe is communicated with the first drain outlet 411, and the condensed water is drained away through the drain pipe.

[0055] This embodiment also provides a temperature and humidity test chamber, including the above-mentioned humidification system for the temperature and humidity test chamber.

[0056] Since the temperature and humidity test chamber adopts the above-mentioned humidification system for the temperature and humidity test chamber, the cost is reduced, and both the working reliability and the environmental friendliness in use are relatively high.

[0057] Further, continue to refer to Figure 1 , the temperature and humidity test chamber further includes a cooling system, a liquid supply system and a liquid return system. The cooling system includes an evaporator 20 arranged inside the temperature and humidity test chamber, and a compressor 30, a condenser 40 and a throttling device (not shown in the figure) arranged outside the temperature and humidity test chamber. The compressor 30, the condenser 40, the throttling device and the evaporator 20 are sequentially communicated to form a refrigerant circulation loop. The liquid inlet of the condenser 40 is communicated with the liquid outlet of the liquid supply system, the liquid outlet of the condenser 40 is communicated with the liquid inlet of the liquid return system, the inlet of the air heat exchanger 500 is communicated with the liquid outlet of the liquid supply system, and the outlet of the air heat exchanger 500 is communicated with the liquid inlet of the liquid return system. By arranging the evaporator 20 inside the box body 10, the air inside the box body 10 can be cooled. By arranging the condenser 40 and the air heat exchanger 500 to share the liquid supply system and the liquid discharge system, the structure of the temperature and humidity test chamber can be simplified.

[0058] Further, the humidifying pipe 200 is arranged above the evaporator 20. With this arrangement, it can be avoided that the hot steam discharged from the humidifying pipe 200 contacts and exchanges heat with the evaporator 20, resulting in the condensation of the hot steam by the evaporator 20, so as to ensure the reliability of the humidifying pipe 200 in humidifying the air.

[0059] Optionally, in this embodiment, the first water receiving tray 600 can also collect the condensed water generated by the evaporator 20.

[0060] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
