[0043] Please refer to FIG1 for details. FIG1 is a flow chart of an embodiment of a dehumidification method provided by the present application.

[0044] As shown in FIG1 , the dehumidification method according to the embodiment of the present application may specifically include the following steps:

[0045] S1, adjusting the humidity in the first space according to a first dehumidification level.

[0046] The dehumidification method provided in the present application is performed by a dehumidification control device.

[0047] Specifically, the dehumidification control device adjusts the humidity in the first space according to the first dehumidification degree. In some embodiments, the first dehumidification degree reflects the dehumidification capacity of the first space.

[0048] In some application scenarios, the dehumidification control device adjusts the humidity in the first space according to the first dehumidification degree to reduce the humidity in the first space.

[0049] In some embodiments, the first dehumidification level is characterized by the ability to adjust the humidity of the first space, for example, reducing the humidity of the first space to 45%, 40%, 39%, 38%, 37%, 36%, 35%, 34%, 33%, 32%, 31%, 30%, 25% or 20%, etc., which is not limited here.

[0050] In some embodiments, the first space may be a relatively closed room or box, for example, a testing room.

[0051] S2, adjusting the humidity in the second space to a target humidity according to a second dehumidification degree.

[0052] The second space is arranged in the first space, the first dehumidification degree is lower than the second dehumidification degree, and the second space is used to accommodate the target object.

[0053] Specifically, the dehumidification control device adjusts the humidity in the second space disposed in the first space to the target humidity according to the second dehumidification degree. In some embodiments, the second dehumidification degree is used to reflect the dehumidification capacity of the second space.

[0054] In some application scenarios, the dehumidification control device adjusts the humidity in the second space according to the second dehumidification degree to reduce the humidity in the second space.

[0055] In some embodiments, the second space may be a relatively closed box or cavity. For example, the second space is a metal cavity.

[0056] In some embodiments, the second dehumidification level is characterized by the ability to adjust the humidity of the second space, for example, reducing the humidity of the second space to 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1% or 0.1%, etc., which is not limited here.

[0057] In some application scenarios, the target humidity is less than 20%. In some application scenarios, the target humidity is less than 10%. In some application scenarios, the target humidity is less than 5%. In some application scenarios, the target humidity is less than 3%.

[0058] In some embodiments, the target object is a semiconductor component, such as a processor device. In some application scenarios, the processor device may be a CPU (Central Processing Unit). In some application scenarios, the processor device may be an integrated circuit chip with signal processing capabilities. In some application scenarios, the processor device may also be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. The general-purpose processor may be a microprocessor, or the processor device may be any conventional processor.

[0059] In some embodiments, the target object is an electronic device, such as a storage medium. In some application scenarios, the storage medium may be a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a flash memory card, a disk, or an optical disk.

[0060] In some embodiments, the target object is a solid-state drive (SSD) without a main control unit. In this case, the target object includes a printed circuit board (PCB), a flash memory chip, or a PCB, a flash memory chip, and a cache chip. In some embodiments, the target object is any one or more of a PCB, a flash memory chip, and a cache chip.

[0061] In some embodiments, the target object is a biological specimen, such as an animal specimen, a plant specimen, an insect specimen, a fossil specimen, a cell specimen, or a virus specimen.

[0062] In some application scenarios, the target object is a biological sample.

[0063] By adjusting the humidity in the second space to the target humidity, the target object accommodated in the second space is maintained within a corresponding humidity range for storage, operation or testing.

[0064] In the above scheme, the humidity in the first space is adjusted according to a first dehumidification level; the humidity in the second space containing the target object is adjusted to a target humidity according to a second dehumidification level, where the first dehumidification level is lower than the second dehumidification level. The dehumidification method of the present application adjusts the humidity in the first space and the second space separately, thereby lowering the humidity in the second space where the target object is located to a lower level, thereby meeting the target object's humidity requirements. It can also alleviate the phenomenon of condensation and frost in the second space due to excessive humidity in low-temperature environments.

[0065] Please refer to FIG2 , which is a flow chart of another embodiment of the dehumidification method provided in the present application.

[0066] As shown in FIG2 , another embodiment of the dehumidification method provided by the present application may specifically include the following steps:

[0067] S11 , using a first dehumidification device to adjust the humidity in the first space and the second space according to a first dehumidification degree.

[0068] Specifically, the dehumidification control device uses the first dehumidification device to adjust the humidity of the first space and the second space according to the first dehumidification degree.

[0069] In some embodiments, the dehumidification control device uses the first dehumidification device to reduce the humidity in the first space according to the first dehumidification degree. In this case, the first dehumidification device dehumidifies the first space.

[0070] In some application scenarios, the first dehumidification device may be an industrial dehumidifier. Optionally, the first dehumidification device may further be an industrial dehumidifier such as a rotary dehumidifier or a compressor dehumidifier, which is not limited here.

[0071] In some application scenarios, the first dehumidification device may be an air conditioner.

[0072] In some embodiments, the first dehumidification level represents the ability of the first dehumidification device to adjust the humidity in the first space and the second space. For example, the first dehumidification device can reduce the humidity in the first space to 45%, 40%, 39%, 38%, 37%, 36%, 35%, 34%, 33%, 32%, 31%, 30%, 25%, or 20%, etc., without limitation herein.

[0073] In some application scenarios, after the second space is connected to the first space, the dehumidification control device uses the first dehumidification device to adjust the humidity in the second space according to the first dehumidification degree. After completing the above steps, the connection between the second space and the first space is disconnected.

[0074] S12: Utilize a second dehumidification device to adjust the humidity in the second space to a target humidity according to a second dehumidification degree.

[0075] The first dehumidification device has a lower dehumidification degree than the second dehumidification device, and the second dehumidification device is disposed in the first space and interacts with the second space. In some embodiments, the second dehumidification device interacts with the second space through gas interaction.

[0076] Specifically, the dehumidification control device uses the second dehumidification device to adjust the humidity in the second space to the target humidity according to the second dehumidification degree.

[0077] Exemplarily, the second dehumidification device contains a solid desiccant, such as any one or more combinations of zeolite molecular sieve, carbon molecular sieve, activated alumina, activated carbon, and silica gel.

[0078] In some application scenarios, the operation of adjusting the humidity in the second space to the target humidity by using the second dehumidification device is an operation of dehumidifying the second space by using the second dehumidification device so that the temperature value in the second space reaches the target humidity.

[0079] In some embodiments, the second dehumidification level represents the ability of the second dehumidification device to adjust the humidity in the second space. For example, the second dehumidification device can reduce the humidity in the second space to 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, or 0.1%, etc., without limitation herein.

[0080] It can be understood that the dehumidification degree of the first dehumidification device is less than that of the second dehumidification device, that is, the first dehumidification device can reduce the humidity of the space to no less than 20%, and the second dehumidification device can further reduce the humidity of the space to 15% or even below.

[0081] In some application scenarios, the target humidity is less than 20%. In some application scenarios, the target humidity is less than 10%. In some application scenarios, the target humidity is less than 5%. In some application scenarios, the target humidity is less than 3%.

[0082] In some embodiments, the second dehumidification device can selectively interact with the first space or the second space. For example, when the second dehumidification device interacts with the first space, it does not interact with the second space. For another example, when the second dehumidification device interacts with the second space, it does not interact with the first space. Optionally, the second dehumidification device interacts with the first space or the second space via gas.

[0083] After a period of research, the inventors of this application found that using only a second dehumidifier to adjust the humidity of the first and second spaces requires a large amount of time and energy to reduce the humidity in the second space to the target humidity due to the limited dehumidification capacity of the second dehumidifier per unit time. Considering the need to save energy and improve efficiency, a first dehumidifier is used to perform a first-level humidity adjustment on the first and / or second spaces, so that the humidity in the first and / or second spaces is lower than a certain range (for example, any one of 10%-15%, 15%-20%, 20%-25%, 20%-30%, or 25-30%), and then a second dehumidifier is used to perform a second-level humidity adjustment on the second space, further adjusting the humidity within the above range to the target humidity (any one of below 10%, below 5%, below 3%, or below 1%), so that the storage, operation, or testing of the target object meets the conditions.

[0084] It is understood that the first dehumidifier performs a first-stage humidity adjustment on the first space and / or the second space. As the first dehumidifier lowers the humidity in the first space and / or the second space, the second dehumidifier's second-stage humidity adjustment on the second space becomes more effective, i.e., the humidity in the second space is even lower. For example, if the humidity in the first space and / or the second space is 10% after dehumidification by the first dehumidifier, the second dehumidifier can further adjust the humidity in the second space based on this, bringing the humidity in the second space closer to 0%.

[0085] In the above scheme, the humidity in the first space is adjusted according to a first dehumidification level; the humidity in the second space containing the target object is adjusted to a target humidity according to a second dehumidification level, where the first dehumidification level is lower than the second dehumidification level. The dehumidification method of the present application adjusts the humidity in the first space and the second space separately, thereby lowering the humidity in the second space where the target object is located to a lower level, thereby meeting the target object's humidity requirements. It can also alleviate the phenomenon of condensation and frost in the second space due to excessive humidity in low-temperature environments.

[0086] Another embodiment of the dehumidification method provided in this application may specifically include the following steps:

[0087] S21 , using a first dehumidification device to adjust the humidity in the first space and the second space according to a first dehumidification degree.

[0088] S22: absorbing the first air in the second space by using the second dehumidification device and injecting the second air into the second space until the humidity in the second space reaches the target humidity.

[0089] The humidity of the second air is lower than the humidity of the first air.

[0090] Specifically, the dehumidification control device uses the second dehumidification equipment to absorb the first air in the second space and injects the second air into the second space until the humidity in the second space reaches the target humidity and then stops.

[0091] In some application scenarios, a suction pump and a discharge pump are provided in the second dehumidification device, and the second dehumidification device is connected to the second space through a first air inlet channel and a first air exhaust channel.

[0092] In some embodiments, the dehumidification control device uses a suction pump to draw the first air through the first air inlet channel into the second dehumidification device for dehumidification. The air after the dehumidification operation is the second air. The dehumidification control device then uses an output pump to inject the second air into the second space through the first exhaust channel, gradually reducing the humidity in the second space. When the humidity in the second space is less than or equal to the target humidity, the second dehumidification device ceases to regulate the humidity in the second space. Optionally, ceasing the humidity regulation in the second space by the second dehumidification device may also include closing the first air inlet channel and the first exhaust channel.

[0093] In the above scheme, the humidity in the first space is adjusted according to a first dehumidification level; the humidity in the second space containing the target object is adjusted to a target humidity according to a second dehumidification level, where the first dehumidification level is lower than the second dehumidification level. The dehumidification method of the present application adjusts the humidity in the first space and the second space separately, thereby lowering the humidity in the second space where the target object is located to a lower level, thereby meeting the target object's humidity requirements. It can also alleviate the phenomenon of condensation and frost in the second space due to excessive humidity in low-temperature environments.

[0094] Another embodiment of the dehumidification method provided in this application may specifically include the following steps:

[0095] S31: Utilize a first dehumidification device to adjust the humidity in the first space and the second space according to a first dehumidification degree.

[0096] S32: Utilize the second dehumidification device to absorb the first air in the second space and inject the second air into the second space.

[0097] S33, evaporating the water molecules in the second dehumidification device into the first space.

[0098] In some embodiments, the second dehumidification device includes a solid dehumidifier. Since the dehumidification capacity of the solid dehumidifier is limited, it can no longer dehumidify the first air if it adsorbs water molecules exceeding a certain threshold. That is, the second dehumidification device cannot meet the dehumidification conditions at this time, and therefore the solid dehumidifier in the second dehumidification device needs to be regenerated.

[0099] In some embodiments, before the step of evaporating the water molecules in the second dehumidification device into the first space, it also includes detecting whether the water molecule content in the second dehumidification device is greater than the water molecule content threshold. If so, the first air inlet channel and the first exhaust channel connecting the second dehumidification device to the second space are closed, and the second air inlet channel and the second exhaust channel connecting the second dehumidification device to the first space are opened to evaporate the water molecules in the second dehumidification device into the first space.

[0100] In some application scenarios, the operation of evaporating water molecules in the second dehumidification device into the first space may specifically include:

[0101] S331 , heating the third air, wherein the third air flows from the first space to the second dehumidification device through the second air inlet channel.

[0102] S332: Utilize the second dehumidification device to absorb the third air and inject the fourth air into the first space.

[0103] The water molecule content in the fourth air is higher than the water molecule content in the third air.

[0104] Specifically, the third air having a temperature higher than that of the solid dehumidifier in the second dehumidification device is used to heat and evaporate the water molecules in the solid dehumidifier, so that the water molecule content in the solid dehumidifier gradually decreases, thereby meeting the requirement of dehumidifying the first air in the second space again.

[0105] It is understandable that the lower the humidity of the third air, the stronger its ability to absorb water molecules, and further, the faster the speed at which the water molecule content in the solid dehumidifier in the second dehumidification device decreases.

[0106] S333: Determine whether the water molecule content in the second dehumidification device is lower than a first threshold.

[0107] If yes, jump to S334; if no, jump to S333.

[0108] S334, close the second air intake channel and the second exhaust channel, and open the first air intake channel and the first exhaust channel.

[0109] After completing the regeneration operation, the solid dehumidifier in the second dehumidification device can re-dehumidify the first air in the second space to obtain second air with lower humidity than the first air, and further inject the second air into the second space to reduce the humidity in the second space.

[0110] In some embodiments, after the third air enters the second dehumidifier, it regenerates the solid dehumidifier in the second dehumidifier, potentially heating the solid dehumidifier. If the temperature of the second space differs from that of the solid dehumidifier, the second air obtained after passing through the second dehumidifier may have a temperature difference with the air in the second space. To maintain a constant temperature in the second space, a heating and / or cooling device may be installed in the second dehumidifier or the first exhaust duct to ensure that the temperature of the second air is consistent with that of the second space. In some embodiments, the heating and / or cooling device is a Peltier (semiconductor cooling / heating plate).

[0111] S34: Utilize the second dehumidification device to absorb the first air in the second space and inject the second air into the second space until the humidity in the second space reaches the target humidity.

[0112] In the above scheme, the humidity in the first space is adjusted according to a first dehumidification level; the humidity in the second space containing the target object is adjusted to a target humidity according to a second dehumidification level, where the first dehumidification level is lower than the second dehumidification level. The dehumidification method of the present application adjusts the humidity in the first space and the second space separately, thereby lowering the humidity in the second space where the target object is located to a lower level, thereby meeting the target object's humidity requirements. It can also alleviate the phenomenon of condensation and frost in the second space due to excessive humidity in low-temperature environments.

[0113] Another embodiment of the dehumidification method provided in this application may specifically include the following steps:

[0114] S41: Utilize a first dehumidification device to adjust the humidity in the first space and the second space according to a first dehumidification degree.

[0115] S42: Utilize the second dehumidification device to absorb the first air in the second space and inject the second air into the second space.

[0116] S43 , during the process of the second dehumidification device dehumidifying the second space, in response to the number of water molecules exceeding a threshold, suspending air exchange between the second dehumidification device and the second space.

[0117] Specifically, on the one hand, in order to prevent the water molecules in the second dehumidification device from evaporating into the second space through the first exhaust channel, and on the other hand, in order to prevent the third air entering the first space from entering the second space through the first exhaust channel and causing the temperature in the second space to change, the dehumidification control device suspends the air exchange between the second dehumidification device and the second space.

[0118] In some embodiments, suspending the air exchange between the second dehumidification device and the second space may include closing the first air intake channel and the first air exhaust channel.

[0119] S44, evaporating the water molecules in the second dehumidification device into the first space.

[0120] S45 , utilizing the second dehumidification device to absorb the first air in the second space and injecting the second air into the second space until the humidity in the second space reaches the target humidity.

[0121] In the above scheme, the humidity in the first space is adjusted according to a first dehumidification level; the humidity in the second space containing the target object is adjusted to a target humidity according to a second dehumidification level, where the first dehumidification level is lower than the second dehumidification level. The dehumidification method of the present application adjusts the humidity in the first space and the second space separately, thereby lowering the humidity in the second space where the target object is located to a lower level, thereby meeting the target object's humidity requirements. It can also alleviate the phenomenon of condensation and frost in the second space due to excessive humidity in low-temperature environments.

[0122] Another embodiment of the dehumidification method provided in this application may specifically include the following steps:

[0123] S51: Utilize a first dehumidification device to adjust the humidity in the first space and the second space according to a first dehumidification degree.

[0124] S52: Utilize the second dehumidification device to absorb the first air in the second space and inject the second air into the second space.

[0125] S53 , during the process of the second dehumidification device dehumidifying the second space, in response to the number of water molecules exceeding a threshold, suspending air exchange between the second dehumidification device and the second space.

[0126] S54, evaporating the water molecules in the second dehumidification device into the first space.

[0127] S55, using the second dehumidification equipment again to exchange air with the second space.

[0128] Specifically, after the water molecules in the second dehumidifier are evaporated, the second dehumidifier meets the dehumidification condition. The dehumidification control device opens the first air inlet channel and the first air outlet channel, and uses the second dehumidifier to exchange air with the second space again, thereby adjusting the air humidity in the second space.

[0129] In some embodiments, the step of the dehumidification control device using the second dehumidification device to exchange air with the second space is to use the second dehumidification device to dehumidify the second space.

[0130] S56: Utilize the second dehumidification device to absorb the first air in the second space and inject the second air into the second space until the humidity in the second space reaches the target humidity.

[0131] In the above scheme, the humidity in the first space is adjusted according to a first dehumidification level; the humidity in the second space containing the target object is adjusted to a target humidity according to a second dehumidification level, where the first dehumidification level is lower than the second dehumidification level. The dehumidification method of the present application adjusts the humidity in the first space and the second space separately, thereby lowering the humidity in the second space where the target object is located to a lower level, thereby meeting the target object's humidity requirements. It can also alleviate the phenomenon of condensation and frost in the second space due to excessive humidity in low-temperature environments.

[0132] Another embodiment of the dehumidification method provided in this application may specifically include the following steps:

[0133] S61: Utilize a first dehumidification device to adjust the humidity in the first space and the second space according to a first dehumidification degree.

[0134] S62: Utilize a second dehumidification device to adjust the humidity in the second space to a target humidity according to a second dehumidification degree.

[0135] Specifically, the second dehumidification device contains a solid hygroscopic material, which is used to absorb water molecules in the air. The solid hygroscopic material includes any one or more of activated carbon, activated alumina, silica gel, carbon molecular sieve and zeolite molecular sieve.

[0136] Furthermore, the solid hygroscopic material must be recyclable. This is because the second dehumidifier cannot directly adjust the humidity in the second space to the target humidity in a single dehumidification cycle. This means that disposable hygroscopic materials like calcium oxide cannot be used. In other words, the solid hygroscopic material must be recyclable, meaning that after some processing, the water molecules within the hygroscopic material can be removed and the second space can be dehumidified again.

[0137] In the above scheme, the humidity in the first space is adjusted according to a first dehumidification level; the humidity in the second space containing the target object is adjusted to a target humidity according to a second dehumidification level, where the first dehumidification level is lower than the second dehumidification level. The dehumidification method of the present application adjusts the humidity in the first space and the second space separately, thereby lowering the humidity in the second space where the target object is located to a lower level, thereby meeting the target object's humidity requirements. It can also alleviate the phenomenon of condensation and frost in the second space due to excessive humidity in low-temperature environments.

[0138] Please refer to Figure 3, which is a flow chart of another embodiment of the dehumidification method provided in this application.

[0139] As shown in FIG3 , another embodiment of the dehumidification method provided by the present application may specifically include the following steps:

[0140] S101, dehumidifying the first space.

[0141] Specifically, the dehumidification control device uses the first-stage dehumidification equipment to dehumidify the first space.

[0142] Among them, the first-stage dehumidification equipment corresponds to the first dehumidification equipment mentioned above, which will not be described here.

[0143] S102: Reduce the humidity in the current first space until the current humidity is less than or equal to 30%.

[0144] Specifically, the dehumidification control device uses the humidity sensor in the first space to obtain the current humidity value in the first space, and determines whether the current humidity value in the first space is less than or equal to 30%. If the condition is not met, the humidity in the first space continues to be reduced.

[0145] S103, completing dehumidification of the first space.

[0146] Specifically, the dehumidification control device stops the dehumidification operation of the first space.

[0147] It is worth noting that, if the humidity sensor in the first space subsequently detects that the humidity in the first space is greater than 30%, the dehumidification control device will re-execute steps S101 to S103.

[0148] S104: Dehumidify the second space.

[0149] The second space accommodates the target object.

[0150] Specifically, the dehumidification control device uses the second-stage dehumidification equipment to dehumidify the second space.

[0151] Among them, the second-stage dehumidification equipment corresponds to the second dehumidification equipment mentioned above, which will not be described here.

[0152] S105: Reduce the humidity in the second space until the current humidity is less than or equal to 5%.

[0153] Specifically, the dehumidification control device uses the humidity sensor in the second space to obtain the current humidity value in the second space, and determines whether the current humidity value in the second space is less than or equal to 5%. If the condition is not met, the humidity in the second space continues to be reduced.

[0154] S106, completing dehumidification of the second space.

[0155] Specifically, the dehumidification control device stops the dehumidification operation of the second space.

[0156] It is worth noting that if the humidity sensor in the second space subsequently detects that the humidity in the second space is greater than 5%, the dehumidification control device will re-execute steps S104-S106. Furthermore, steps S101-S103 and S104-S106 can be performed in sequence or simultaneously, which is not limited here.

[0157] S107, cooling the second space.

[0158] Specifically, a refrigeration device is further provided in the second space, and the dehumidification control device uses the refrigeration device to perform a temperature-lowering operation on the second space.

[0159] In some embodiments, the refrigeration device is a semiconductor refrigeration chip. In some embodiments, the refrigeration device is a refrigeration liquid such as liquid nitrogen, liquid oxygen, liquid helium, dry ice, or a refrigeration solid.

[0160] After a period of research, the inventors of this application discovered that if the surface temperature of a low-temperature object (i.e., a target object) is below the dew point of the air and the air's water saturation reaches 100%, condensation and / or frosting will form on the surface of the low-temperature object. The extent of frosting and / or condensation on the target object's surface depends on the target object's surface temperature, the relative humidity of the environment, or the water content of the air.

[0161] Taking semiconductor devices as an example, in some application scenarios, semiconductor devices need to be installed on a test board to undergo low-temperature operation testing. If the humidity in the air is high, as the temperature drops, frost and / or condensation may appear on the surface of the semiconductor device or the test board. The frost and / or condensation on the surface of the semiconductor device or the test board can easily cause the semiconductor device or the test board to be damaged due to a short circuit.

[0162] Taking biological samples as an example, in some application scenarios, biological samples need to be observed or experimented in a low-temperature environment. If the humidity in the air is high, as the temperature drops, frost and / or condensation may appear on the surface of the biological samples and / or experimental equipment, which is not conducive to the immediate observation of the experimenter.

[0163] S108, adjusting the temperature of the second space until the current temperature is equal to the preset temperature.

[0164] Specifically, a temperature sensor is also provided in the second space. The dehumidification control device uses the temperature sensor to detect the current temperature value in the second space and determines whether the current temperature value is equal to the preset temperature. If the condition is not met, the humidity in the second space continues to be adjusted.

[0165] Optionally, the preset temperature is -40 degrees Celsius, -41 degrees Celsius, -42 degrees Celsius, -43 degrees Celsius, -44 degrees Celsius, -45 degrees Celsius, -46 degrees Celsius, -47 degrees Celsius, -48 degrees Celsius, -49 degrees Celsius, or -50 degrees Celsius. In some application scenarios, the preset temperature may be a preset temperature interval, and the preset temperature interval may be -50 degrees Celsius to -40 degrees Celsius, -50 degrees Celsius to -45 degrees Celsius, or -45 degrees Celsius to -40 degrees Celsius, which is not limited here.

[0166] S109, the second space cooling is completed.

[0167] Methods used by those skilled in the art to prevent frost on a target object at low temperatures mainly include using a heating element to heat the surface of the target object, applying an anti-frost coating on the surface of the target object, using a dehumidifier or air conditioner to control the ambient humidity, or vibrating the target object to prevent water vapor from adhering.

[0168] The inventors of this application have found that the above-mentioned conventional technical means all have certain shortcomings: the method of using a heating element to heat the surface of the target object makes it difficult to maintain the target object at a preset temperature, thereby failing to meet the testing and / or working requirements of the target object; the method of coating the surface of the target object may cause damage to the target object, and if the number of target objects is large, it is also difficult to coat the surface of the target objects in large quantities; the use of a dehumidifier commonly found in this field can only control the ambient humidity to above 10%, and if the target temperature is lower than -40 degrees Celsius, frost will still form on the surface of the target object; mechanically vibrating the target object is not suitable for target objects that are not resistant to vibration.

[0169] Furthermore, the inventors discovered that using only solid desiccant agents, such as zeolite molecular sieves, for humidity control suffers from low dehumidification efficiency. Once a solid desiccant absorbs a small amount of water vapor from the air, it loses its hygroscopic capacity and requires regeneration to regain its hygroscopic capacity. Consequently, relying solely on solid desiccant agents for humidity control requires significant time and energy to reduce the humidity in the second space to below 10%, resulting in low efficiency and high energy consumption.

[0170] It is precisely to address the shortcomings of the above-mentioned defrosting / dehumidifying methods that the inventors of the present application proposed the above-mentioned dehumidification method, which can further reduce the humidity of the second space accommodating the target object, and control the humidity in the second space within a very small range (for example, the humidity is controlled below 5%) without the assistance of other auxiliary dehumidification methods, so that frost and / or condensation will not occur on the surface of the target object at the target temperature.

[0171] The above scheme adjusts the humidity of the first space and the second space respectively, which can reduce the humidity of the second space where the target object is located to a lower level, thereby meeting the humidity requirements of the target object, and can also alleviate the phenomenon of condensation and frost in the second space due to excessive humidity in a low temperature environment.

[0172] Please refer to Figure 4, which is a schematic diagram of the structure of an embodiment of a test device provided by the present application. The test device 100 of the embodiment of the present application includes a first space 11 and a second space 12.

[0173] In some embodiments, the first space 11 is a test cabinet.

[0174] In some application scenarios, the number of the first space 11 is 1. In some application scenarios, the number of the first space 11 is not less than one.

[0175] In some embodiments, the second space 12 is a test box.

[0176] In some application scenarios, the number of the second space 12 is 1. In some application scenarios, the number of the second space 12 is not less than one.

[0177] It can be understood that the volume of the first space 11 is greater than the volume of the second space 12 .

[0178] A first dehumidifier 111 and a second dehumidifier 112 are provided within the first space 11. The second dehumidifier 112 interacts with the first space 11 and the second space 12. Specifically, the second dehumidifier 112 is connected to the second space 12 via a first air intake channel 13 and a first air exhaust channel 14. The second dehumidifier 112 is connected to the first space 11 via a second air intake channel 15 and a second air exhaust channel 16.

[0179] In some embodiments, the first dehumidification device 111 may be an air conditioner or a dehumidifier. The first dehumidification device 111 is used to reduce the humidity in the first space.

[0180] In some embodiments, the second dehumidification device 112 includes a solid dehumidifier. For example, the solid dehumidifier includes zeolite molecular sieve.

[0181] The second space 12 is disposed in the first space 11 . Furthermore, the second space 12 also accommodates a target object 121 and a test component 122 .

[0182] In some application scenarios, the target object 121 is a semiconductor device.

[0183] In some embodiments, the target object 121 is an electronic device, such as a storage medium. In some application scenarios, the storage medium may be a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a flash memory card, a disk, or an optical disk.

[0184] In some application scenarios, target object 121 is a solid-state drive without a main control unit. In this case, target object 121 includes a printed circuit board, a flash memory chip, or a printed circuit board, a flash memory chip, and a cache chip. In some embodiments, target object 121 is any one or more of a printed circuit board, a flash memory chip, and a cache chip.

[0185] In some application scenarios, the target object 121 is a biological specimen, such as an animal specimen, a plant specimen, an insect specimen, a fossil specimen, a cell specimen, or a virus specimen.

[0186] In some application scenarios, the target object 121 is a biological sample.

[0187] In some embodiments, the test component 122 is a test printed circuit board. In some application scenarios, the test component 122 is a test base, which is used to couple with the target object 121 to enable the target object 121 to work or be tested.

[0188] In some application scenarios, the testing component 122 may be a sampling device. In some application scenarios, the testing component 122 may be a cryo-microscope, which is not limited here.

[0189] The testing device 100 performs dehumidification according to the above-mentioned dehumidification method, so that the humidity in the second space 12 meets the testing requirements of the testing component 122 on the target object 121 at the target temperature.

[0190] Specifically, the test equipment 100 uses the second dehumidification equipment 112 to absorb the first air in the second space 12 through the first air inlet channel 13. The second dehumidification equipment 112 dehumidifies the first air to obtain the second air, and discharges the second air to the second space 12 through the first exhaust channel 14 until the humidity in the second space 12 reaches the target humidity.

[0191] It is worth noting that when the second dehumidifier 112 interacts with the second space 12, the second air inlet channel 15 and the second air outlet channel 16 are closed to prevent the second space 12 from communicating with the first space 11 and thereby increasing the humidity in the second space 12. Similarly, when the second dehumidifier 112 interacts with the first space 11, the first air inlet channel 13 and the first air outlet channel 14 are closed.

[0192] Understandably, the second dehumidifier 112 has a limited ability to absorb moisture molecules from the air in the second space 12. When the second dehumidifier 112's dehumidification capacity is insufficient, the first air inlet channel 13 and the first air outlet channel 14 are closed. At this point, the second dehumidifier 112 interacts with the first space 11, including opening the second air inlet channel 15 and the second air outlet channel 16.

[0193] To accelerate the evaporation of water molecules from second dehumidifier 112 into the first space, in some embodiments, a heating device is installed in second air inlet channel 15, ensuring that the temperature of the third air entering second dehumidifier 112 through second air inlet channel 15 is higher than that of the second dehumidifier. After the dehumidification capacity of second dehumidifier 112 is restored, second air inlet channel 15 and second air outlet channel 16 are closed, first air inlet channel 13 and first air outlet channel 14 are opened, and air exchange between second dehumidifier 112 and second space 12 is resumed.

[0194] Furthermore, the test requirement is that no frost forms at a target temperature, for example, the test requirement is that no frost forms within a temperature range of -30 degrees Celsius to -50 degrees Celsius.

[0195] In the above scheme, the humidity in the first space is adjusted according to a first dehumidification level; the humidity in the second space containing the target object is adjusted to a target humidity according to a second dehumidification level, where the first dehumidification level is lower than the second dehumidification level. The dehumidification method of the present application adjusts the humidity in the first space and the second space separately, thereby lowering the humidity in the second space where the target object is located to a lower level, thereby meeting the target object's humidity requirements. It can also alleviate the phenomenon of condensation and frost in the second space due to excessive humidity in low-temperature environments.

[0196] Please refer to Figure 5 , which is a schematic diagram of the structure of an embodiment of a test workshop provided by the present application. The test workshop 200 of the embodiment of the present application includes a first space 21 and a second space 22 .

[0197] In some embodiments, the first space 21 is a testing chamber.

[0198] In some embodiments, the first space 21 is a test cabinet.

[0199] In some embodiments, the second space 22 is a test box.

[0200] It can be understood that the volume of the first space 21 is greater than the volume of the second space 22 .

[0201] A first dehumidifier 211 and a second dehumidifier 212 are provided within the first space 21. The second dehumidifier 212 interacts with the first space 21 and the second space 22. Specifically, the second dehumidifier 212 is connected to the second space 22 via a first air intake channel 23 and a first air exhaust channel 24. The second dehumidifier 212 is connected to the first space 21 via a second air intake channel 25 and a second air exhaust channel 26.

[0202] In some embodiments, the first dehumidification device 211 may be an air conditioner or a dehumidifier. The first dehumidification device 211 is used to reduce the humidity in the first space.

[0203] In some embodiments, the second dehumidification device 212 includes a solid dehumidifier, for example, a zeolite molecular sieve.

[0204] The second space 22 is disposed in the first space 21 . Furthermore, the second space 22 also accommodates a target object 221 and a test component 222 .

[0205] In some application scenarios, the target object 221 is a semiconductor device.

[0206] In some embodiments, the target object 221 is an electronic device, such as a storage medium. In some application scenarios, the storage medium may be a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a flash memory card, a disk, or an optical disk.

[0207] In some application scenarios, target object 221 is a solid-state drive without a main control unit. In this case, target object 221 includes a printed circuit board, a flash memory chip, or a printed circuit board, a flash memory chip, and a cache chip. In some embodiments, target object 221 is any one or more of a printed circuit board, a flash memory chip, and a cache chip.

[0208] In some application scenarios, the target object 221 is a biological specimen, such as an animal specimen, a plant specimen, an insect specimen, a fossil specimen, a cell specimen, or a virus specimen.

[0209] In some application scenarios, the target object 221 is a biological sample.

[0210] In some embodiments, the test component 222 is a test printed circuit board. In some application scenarios, the test component 222 is a test base, which is used to couple with the target object 221 to enable the target object 221 to work or be tested.

[0211] In some application scenarios, the testing component 222 may be a sampling device. In some application scenarios, the testing component 222 may be a cryo-microscope, which is not limited here.

[0212] Specifically, the test workshop 200 uses the second dehumidification equipment 212 to absorb the first air in the second space 22 through the first air inlet channel 23. The second dehumidification equipment 212 dehumidifies the first air to obtain the second air, and discharges the second air to the second space 22 through the first exhaust channel 24 until the humidity in the second space 22 reaches the target humidity.

[0213] It is worth noting that when the second dehumidification device 212 interacts with the second space 22, the second air inlet channel 25 and the second air outlet channel 26 are closed to prevent the second space 22 from communicating with the first space 21 and thereby increasing the humidity in the second space 22. Similarly, when the second dehumidification device 212 interacts with the first space 21, the first air inlet channel 23 and the first air outlet channel 24 are closed.

[0214] Understandably, the second dehumidifier 212 has a limited ability to absorb moisture molecules from the air in the second space 22. When the second dehumidifier 212's dehumidification capacity is insufficient, the first air inlet channel 23 and the first air outlet channel 24 are closed. At this point, the second dehumidifier 212 interacts with the first space 21, including opening the second air inlet channel 25 and the second air outlet channel 26.

[0215] To accelerate the evaporation of water molecules from the second dehumidifier 212 into the first space, in some embodiments, a heating device is installed in the second air inlet channel 25, ensuring that the temperature of the third air entering the second dehumidifier 212 through the second air inlet channel 25 is higher than that of the second dehumidifier. After the dehumidification capacity of the second dehumidifier 212 is restored, the second air inlet channel 25 and the second air outlet channel 26 are closed, and the first air inlet channel 23 and the first air outlet channel 24 are opened, allowing the second dehumidifier 212 to exchange air with the second space 22 again.

[0216] In some embodiments, after the third air enters the second dehumidifier 212 and regenerates the solid dehumidifier in the second dehumidifier 212, the solid dehumidifier may be heated. If the temperature within the second space 22 differs from the temperature of the solid dehumidifier, a temperature difference may form between the second air obtained after passing through the second dehumidifier 212 and the air within the second space 22. To maintain a constant temperature within the second space 22, a heating and / or cooling device may be provided on the second dehumidifier 212 or the first exhaust duct 24 to ensure that the temperature of the second air is consistent with that of the second space 22. In some embodiments, the heating and / or cooling device is a Peltier (semiconductor cooling / heating plate).

[0217] In some embodiments, the test requirement is that no frost forms at a target temperature, for example, the test requirement is that no frost forms at a temperature range of -30 degrees Celsius to -50 degrees Celsius.

[0218] In the above scheme, the humidity in the first space is adjusted according to a first dehumidification level; the humidity in the second space containing the target object is adjusted to a target humidity according to a second dehumidification level, where the first dehumidification level is lower than the second dehumidification level. The dehumidification method of the present application adjusts the humidity in the first space and the second space separately, thereby lowering the humidity in the second space where the target object is located to a lower level, thereby meeting the target object's humidity requirements. It can also alleviate the phenomenon of condensation and frost in the second space due to excessive humidity in low-temperature environments.

[0219] Please refer to Figure 6, which is a schematic diagram of the structure of an embodiment of the test device provided by the present application. The test device 300 provided by the present application includes a first cavity 31 and a second cavity 32. The first cavity 31 and the second cavity 32 correspond to the first space and the second space mentioned above, respectively, and are not further described here.

[0220] The second cavity 32 is disposed in the first cavity 31. The first cavity 31 is further provided with a first dehumidification device 311 and a second dehumidification device 312. In this embodiment, the first dehumidification device 311 is a central air conditioner or an industrial dehumidifier, and the second dehumidification device 312 is a zeolite molecular sieve.

[0221] Furthermore, a target object 321 , a test component 322 and a cold stage 323 are also disposed in the second cavity 32 .

[0222] In some embodiments, the target object 321 is a semiconductor component, such as a processor device. In some application scenarios, the processor device may be a CPU (Central Processing Unit). In some application scenarios, the processor device may be an integrated circuit chip with signal processing capabilities. In some application scenarios, the processor device may also be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components.

[0224] In some embodiments, the target object 321 is a solid-state drive without a main control unit. In this case, the target object includes a printed circuit board, a flash memory chip, or a printed circuit board, a flash memory chip, and a cache chip. In some embodiments, the target object is any one or more of a printed circuit board, a flash memory chip, and a cache chip.

[0225] The test component 322 in this embodiment is a test board for performing tests on the target object 321, and the cold stage 323 is a semiconductor refrigeration component, which enables the target object to be cooled from a first temperature range of 0℃ to 110℃ to a second temperature range of -60℃ to -20℃ for low temperature testing.

[0226] Furthermore, the second dehumidifier 312 interacts with the first cavity 31 and the second cavity 32. Specifically, the second dehumidifier 312 is connected to the second cavity 32 via the first air inlet channel 33 and the first air outlet channel 34, and the second dehumidifier 312 is connected to the first cavity 31 via the second air inlet channel 35 and the second air outlet channel 36.

[0227] Among them, the specific interaction mode between the second dehumidification device 312 and the first cavity 31 and the second cavity 32 can be found in the above interaction mode between the second dehumidification device 212 and the first space 21 and the second space 22, which will not be repeated here.

[0228] In the above scheme, the humidity in the first space is adjusted according to a first dehumidification level; the humidity in the second space containing the target object is adjusted to a target humidity according to a second dehumidification level, where the first dehumidification level is lower than the second dehumidification level.
