Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of humidity control, and specifically, relates to a humidity control device. Background Art
[0002] With the rapid development of the energy storage industry, the trend of large capacity and high power density of energy storage equipment has become increasingly obvious, resulting in higher and higher requirements for heat dissipation design, and the application of liquid cooling, an efficient cooling method, has become more and more common. Usually, the cooling system in the energy storage system relies on the drive of the chiller to transport the low-temperature coolant to the cooling unit of equipment such as the battery pack and PCS, and remove the heat of the equipment through convection heat transfer. However, when the ambient temperature and humidity are high, the low-temperature coolant causes the temperature of the cooling unit on the equipment to be lower than the ambient temperature and the temperature in the equipment cabin, which can easily cause condensation near the cooling unit inside the equipment to produce condensed water, causing electrical insulation failure, short circuit and other problems, and even causing safety accidents such as component burning, fire, and explosion.
[0003] At present, there are many finished dehumidifiers on the market that rely on thermoelectric refrigeration. When arranged, both the cold end and the hot end are inside the equipment cabin that needs to be dehumidified. In fact, the heat is circulating internally. In addition, the internal space of the equipment cabin is limited, and there are many restrictions on the layout. These factors lead to low dehumidification efficiency and insufficient dehumidification capacity of finished dehumidifiers, making it difficult to meet the dehumidification needs of energy storage equipment. Therefore, it is necessary to develop a humidity control device and system that can effectively control the humidity in the equipment cabin without affecting the heat dissipation effect of liquid cooling to prevent the occurrence of condensation.

DETAILED DESCRIPTION
[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The embodiments described in this application are only part of the embodiments of the utility model, not all of them. Based on the spirit of the utility model, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the utility model.
[0034] like Figure 1 As shown, embodiment 1 of the present application provides a humidity control device, including a humidity control module 20 , a control module 30 and a first box body 10 .
[0035] The first box body 10 includes a first opening 101, a second opening 102, a third opening 103 and a fourth opening 104; the humidity control module 20 is disposed at the third opening 103 of the first box body and partially extends into the first box body 10; the control module 30 is disposed inside the first box body 10;
[0036] The humidity control device further includes a temperature and humidity sensor 40 ; the humidity control device is disposed outside the regulated equipment compartment 110 , and is connected to the regulated equipment compartment 110 through a first pipeline 90 and a second pipeline 100 .
[0037] The humidity control module 20 is a thermoelectric cooling module, including a cold end 201 and a hot end 202. The cold end 201 extends into the first box body 10, and the hot end 202 is outside the first box body 10. The thermoelectric cooling module is small in size, does not introduce noise and vibration problems, does not require refrigerant, and is environmentally friendly.
[0038] The hot end 202 of the thermoelectric cooling module is provided with a first heat dissipation fan 203, which can ensure a good heat dissipation effect at the hot end to ensure a low temperature at the cold end and achieve a good humidity control effect.
[0039] After the humidity control module 20 is installed, the third opening 103 of the first box body is sealed, and the sealing method includes a sealing ring and a sealant. The good sealing of the first box body 10 can effectively prevent the humidity control area from exchanging water vapor with the outside world, which is conducive to ensuring a good humidity control effect.
[0040] The temperature and humidity sensor 40 includes a temperature sensor 41 and a humidity sensor 42, which are integrated and arranged on the control module 30. In this arrangement, the device structure is simple and compact, and internal wiring is reduced.
[0041] In a preferred but non-limiting embodiment of the present invention, Figure 2 As shown, the temperature and humidity sensor 40 is arranged inside the first box body 10, and the arrangement position can be flexibly selected according to actual needs.
[0042] Further preferably, Figure 3 As shown, the temperature and humidity sensor 40 is arranged inside the regulated equipment compartment 110, which can reflect the actual situation inside the regulated equipment compartment 110 in real time and improve the accuracy of humidity control.
[0043] like Figure 4 As shown, the humidity control device also includes a power module 50, which is arranged inside the first box body 10. In this way, there is no need to make protection requirements for the battery module itself, which facilitates the design or selection of the power module and reduces costs.
[0044] In a preferred but non-limiting embodiment of the present invention, Figure 5 As shown, the humidity control device also includes a second box body 60, and the power module 50 is arranged inside the second box body 60, so that the power module is not exposed to the high temperature and high humidity environment that may exist inside the first box body, which can reduce the use environment requirements when designing or selecting the battery module, reduce costs, and increase service life.
[0045] Further preferably, Figure 6 As shown, the power module 50 is arranged outside and exposed to the environment. This arrangement requires the battery module itself to have a high level of protection, but the arrangement position can be flexibly adjusted to facilitate the deployment of humidity control devices in various complex application scenarios.
[0046] like Figure 7 As shown, the first box body 10 further includes a fourth opening 104 located at the bottom of the first box body 10 .
[0047] The humidity control device further includes a water guide 70, which is arranged below the cold end 201 of the humidity control module and partially extends out of the first box body 10 through the fourth opening 104, and is used to receive condensed water dripping from the cold end 201 and guide it out of the first box body 10. The design of the water guide is conducive to collecting and discharging the condensed water inside the first box body, and preventing the condensed water from evaporating and increasing the humidity in the cabin when the humidity control module is not working.
[0048] After the water guide 70 is installed, the fourth opening 104 of the first box body is sealed, and the sealing method includes a sealing ring and a sealant. The good sealing of the first box body 10 can effectively prevent the humidity control area from exchanging water vapor with the outside, which is conducive to ensuring a good humidity control effect.
[0049] In a preferred but non-limiting embodiment of the present invention, the surface of the water guide 70 is coated with a hydrophobic coating, which can more effectively gather the condensed water flow and maximize the drainage effect.
[0050] The humidity control device also includes a drain valve 80, the opening and closing state of which can be controlled by the control module 30. The control module 30 can specify an operation strategy in real time according to the temperature and humidity conditions by controlling the linkage between the humidity control function module 20 and the drain valve 80, thereby ensuring and improving the humidity control effect of the humidity control device.
[0051] In a preferred but non-limiting embodiment of the present invention, the drain valve 80 is any one of a solenoid valve and an electric ball valve. The solenoid valve can achieve fine opening control to better ensure the drainage effect; the electric ball valve only has two states, open and closed, and is reliable in operation and has a long service life.
[0052] The drain valve 80 is connected to the portion of the water guide 70 extending out of the first box body 10 through a threaded connection, so as to realize opening the valve to discharge condensed water and closing the valve to seal the first box body 10. The threaded connection is sealed by raw tape or glue, and a good seal of the first box body 10 can effectively prevent the humidity control area from exchanging water vapor with the outside world, which is conducive to ensuring a good humidity control effect.
[0053] The control module 30 controls the drain valve 80 to open and drain water at a fixed time through a program. This strategy does not pay attention to the actual amount of condensed water generated. The opening cycle is determined based on the previous equipment test results. The control strategy is simple and does not require additional equipment.
[0054] Preferably, the control module 30 controls the drain valve 80 through a program to open the valve to drain water after the condensed water accumulates to a set water level. This strategy can achieve precise control of drainage, and drainage is started only when a certain amount of condensed water is reached, but corresponding detection components need to be added.
[0055] like Figure 8 As shown, Example 2 of the present application provides a humidity control system, including a regulated equipment compartment 110, a first pipeline 90, a second pipeline 100 and at least one set of humidity control devices as described above; the first box body 10 of the humidity control device also includes a first opening 101 and a second opening 102; the regulated equipment compartment is provided with a fifth opening 1101 and a sixth opening 1102; the first pipeline 90 connects the first opening 101 of the humidity control device and the fifth opening 1101 of the regulated equipment compartment; the second pipeline 100 connects the second opening 102 of the humidity control device and the sixth opening 1102 of the regulated equipment compartment.
[0056] The interior of the regulated equipment compartment 110, the first pipeline 90, the second pipeline 100 and the interior of the first box body 10 together constitute a closed humidity control area. The control module 30 controls the start and stop of the humidity control module 20 and the opening and closing of the drain valve 80 to achieve accurate and efficient humidity control in the area.
[0057] The beneficial effects of the utility model are as follows:
[0058] (1) The humidity control device of the present application guides the moisture in the controlled equipment compartment to condense on the outside, which can effectively reduce the safety hazards of the equipment such as insulation failure and short circuit caused by condensation.
[0059] (2) The humidity control device of the present application is arranged outside the equipment cabin to be controlled. While achieving the humidity control effect, it will not change the temperature in the cabin and will not cause negative effects due to temperature differences.
[0060] (3) The humidity control device of the present application is not limited by the space of the regulated equipment itself, and can be conveniently designed according to needs, making it easy to achieve good humidity control efficiency and a large dehumidification capacity.
[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
