Abstract
The utility model discloses a dehumidifying dampproof cabinet with a semiconductor. A semiconductor dehumidifying machine core 1 is arranged in the space of a relatively sealed cabinet. The cold and hot ends of a semiconductor refrigerating device are respectively connected with a porous condenser 3 and a radiator 4. A draught fan 5 which is used for pumping low wet cold air in a fixing direction to the radiator for heat exchange is arranged close to the radiator. The utility model which is especially suitable for being used as a collecting cabinet for camera apparatuses, magnetic tapes, magnetic discs, optical discs, etc. has the advantages of no temperature difference with the environment, low energy consumption, and automatic control.
Description
The utility model belongs to bin, especially high-grade moistureproof manufacturing field of hiding cabinet.
Along with popularizing of the arrival of information age and electronic teaching, people need be with some important objects, as shoot with video-corder and look (singing) dish, CD-ROM and lantern slide, transparency etc. as equipment, tape, disk, laser and carry out protection against the tide and receive and keep, and go mouldy in case it makes moist.At present, people generally adopt indoor dehumidifier to reach this purpose, but dehumidifier is that the whole interior space is carried out protection against the tide, and energy consumption is big, very flexible, especially at depositing object more after a little while, it is uneconomical more to seem.
The purpose of this utility model is a kind of semi-conductor dehumidifying moisture-resistant cabinet of design, makes its above shortcoming that can overcome prior art, and makes the inside and outside no temperature difference of cabinet, energy consumption is low, autocontrol performance is good advantage.
The purpose of this utility model is to realize by following design.
The semi-conductor dehumidifying moisture-resistant cabinet is made up of cabinet and desiccant body, and a dehumidifying movement is set in the space in the cabinet of sealing relatively; In the dehumidifying movement: the cold junction of semiconductor cooler is associated on the cold plate, and hot junction and radiator link, and one is used for that low temperature cold air orientation is evacuated to blower fan that radiator carries out heat exchange is arranged near the radiator; Dehumidifying movement bottom is provided with the outlet pipe interface of guiding condensed water outside cabinet.
After having adopted design as above, in the cabinet air behind condenser, contained moisture content dewfall and being excluded outside the cabinet on cold plate; The spreader surface of flowing through under the guiding of low humidity cold air at blower fan behind the cold plate with radiator generation heat exchange, becomes with cabinet external environment temperature dry low-grade fever air very nearly the same and flows back in the cabinet.Because dry low-grade fever air rises, flow downward again after becoming condensation air after the moisture absorption, in cabinet, form an air-flow dynamic circulation, whole dehumidification process carries out with the rule circulation of humid air in humid air in: the cabinet → (condensation after drying) low humidity cold air → (after the heat absorption behind the radiator) low-grade fever dry air → (becoming after the moisture absorption in cabinet) cabinet, makes that wet part of air is lowered and maintains on a certain suitable degree in the cabinet.
Because air is heated up by radiator again after the cold plate cooling in the cabinet, suitable selector and controlled condition, can on macroscopic view, make the temperature of air in the cabinet and environment temperature comparable, the no temperature difference exists, so it is consistent with the outer room temperature of cabinet all the time to be deposited object, so both capable of reducing energy consumption, make that again being deposited object can take out use at any time and not have the drawback of dewfall at room temperature.
Description of drawings is as follows.
Fig. 1 is the outside drawing of the utility model embodiment.
Fig. 2 is the side sectional structure chart of the utility model embodiment.
Fig. 3 is the partial sectional view of dehumidifying movement of the present utility model.
Fig. 4 is the outside drawing of radiator.
Fig. 5 is the outside drawing of cold plate.
Fig. 6 is the work block diagram of MCS.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.
In Fig. 1 and Fig. 2, the dehumidifying movement is placed in the interior space of cabinet of relative sealing, generally is placed on below in the cabinet, and the outer below of cabinet is equipped with water storage dish 9; Be provided with behind the door at cabinet and be convenient to the plastic cement magnetic stripe 8 that makes the cabinet door airtight.
Can see among Fig. 3, the essential structure of dehumidifying movement 1: the cold junction of semiconductor cooler 2 and cold plate 3 link, 12 is adiabatic installing rack, and semiconductor cooler hot junction and radiator 4 link, and is used for that the low humidity cold air is evacuated to axial flow blower 5 that radiator carries out heat exchange and is arranged near the radiator.The dehumidifier bottom is provided with the outlet pipe interface 6 of drawing condensed water outside cabinet.The basic structure of radiator as shown in Figure 4.Can find out in conjunction with Fig. 5, the essential structure of cold plate, plate is provided with eyelet 7 and groove 11, so that the condensation exchange is more abundant; For condensed water can be derived preferably, the lower end of cold plate is provided with the condensate water guide structure: the cold plate lower end has a water angle 10, and is aided with gutter 13.
What Fig. 6 exemplified is the operated by rotary motion of humidity control in the cabinet, and these settings are conventional basically.20 is transformer, in this example, civil power is reduced to 12V, and 3A becomes the direct current of 12V behind rectifier 21, and 22 is controllable silicon, and 23 is wave filter, and 2 is semiconductor cooler, and 5 is the direct current axial flow blower.
24 hygrometric degree of sensor signal is input to driver 26 with the controlled humidity index that is preset in the comparison amplifier 25 after relatively also amplifying, with control silicon controlled conducting degree, finally reach the purpose of humidity regulation in the cabinet with control refrigerator electric current or fan delivery.
Sensor 4 can be humidity sensor, also can be temperature sensor, during for the latter, can come humidity in the switch board by measuring condenser temperature and ambient temperature differences.
In an embodiment, test in the moisture-resistant cabinet of a conventional bookcase size, semiconductor cooler adopts 12703 (3A12V), has obtained gratifying effect.
In reality is implemented, detect and the setting of control system also can increase some other auxiliary circuit, such as overheating protection circuit etc.Also can be provided with in the system manually--automatic change-over, to be selected for use according to different situations.
