Description
Technical field
The present invention relates to a kind of computer cabinet, relate in particular to a kind of constant temperature dehumidification rack.
Background technology
Existing computer cabinet structure is generally: several computer racks are located in the rack, but often because the heating of electronic devices and components, system is unstable a strong ventilation facility even cause easily, can use long-pending full dust to make hardware short worried serviceable life because of long-time equally, therefore the machine room that must build the constant temperature strong-force exhaust solves, but the cost of machine room is very expensive, and needs the professional to safeguard etc., and this most of enterprises and institutions reason of hanging back often.Design thus a kind of constant temperature dustproof computer rack, all be to adopt evaporation tube to be embedded in container inner wall to realize to the refrigeration cool-down of a container generally, can cause the container inner wall frosting like this, in the course of time frosting meeting is very serious, if use computer cabinet, then under the heating element effect, circuit board and components and parts can produce serious condensation and burn the computing machine components and parts.Be exactly that air-cooled Defrost method occurs in addition, can eliminate the frost in the container, but can't solve the condensation water problem, in general thinking concept, it is unique method that cold and hot exchange is finished in a container, and cold air directly acts on container, object in the cooled containers, owing to finish cold and hot exchange in same container, the condensate water wall cling phenomenon is insurmountable in the middle and lower part of container, generally is designed with the lower channel of condensate water more.Obviously this is the working environment that can't be applied to accurate electronic devices and components.
The patent No. such as before application is 2011203333925, name is called the movably Chinese utility model patent of thermostatic dustproof type computer cluster system, it is provided with refrigerating plant in cabinet, keep constant by checking the temperature controller in-cabinet temperature, has guaranteed system stability work.But just there is above-mentioned shortcoming in this device: the computer cabinet inwall produces condensation even frost easily, might cause damage to equipment within machine cabinet.
Summary of the invention
The present invention mainly is the problem that solves the prior art existing easy generation condensation of Computer rack even frosting, and a kind of constant temperature dehumidification rack that can keep air dried in the rack, guarantee the computer cabinet long-term stable operation is provided.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: a kind of constant temperature dehumidification rack, consisted of by cabinet and cabinet door, cabinet comprises the air compartment that on top, the hardware chamber at middle part and the refrigerated dehumidification chamber of bottom, go out air compartment and the refrigerated dehumidification chamber is connected by the air channel, at the indoor refrigerated dehumidification device that is provided with of refrigerated dehumidification, the indoor cold and hot air exchange chamber that also is provided with of described refrigerated dehumidification, be provided with dividing plate in the middle of the cold and hot air exchange chamber and cold and hot air exchange chamber be separated into damp-heat air discharges the chamber and cold dry air detaches the chamber, being provided with through hole on the dividing plate discharges chamber and cold dry air with damp-heat air and detaches the chamber and be connected, in discharging the chamber, damp-heat air is provided with evaporator, damp-heat air discharges on the wall of chamber and has air inlet, air inlet is connected to bottom, hardware chamber, damp-heat air discharges the bottom, chamber and is provided with condensation-water drain, detach the part wall at cold dry air and have air outlet, air outlet is connected with the air channel.Among the present invention cold and hot air exchange is separated from hardware is indoor, be provided with specially cold and hot air exchange chamber, hardware chamber and cold and hot air exchange chamber form independent seal cavity for son, the centre is connected by air outlet, like this so that cold and hot air exchange in special seal cavity, carry out, guaranteed that the hardware chamber is in the environment of relatively dry low temperature all the time, has solved the possibility of condensation.Again the damp-heat air switch room is divided in addition two zones that function is different, be that damp-heat air discharges the chamber and cold dry air detaches the chamber, lower in working order, damp-heat air is sent to the damp-heat air release room, run into the evaporator kapillary that is under the low-temperature condition, discharge condensate water, flow to condensation-water drain along tube wall, hot-air is cooled simultaneously.
As a kind of preferred version, described refrigerated dehumidification chamber is arranged in the drawer type casing, has opening in the side of cabinet bottom, and this drawer type casing is inserted in the cabinet bottom by opening, is fixed with cover plate at opening.The present invention has carried out modular design, and the refrigerated dehumidification chamber is integrated in the drawer type casing, has realized drawing and pulling type unit mounting means, is convenient to efficiently examination and maintenance.
As a kind of preferred version, the sealed chamber of described cold and hot air exchange chamber for being constituted by warming plate.The quad seal chamber that this cold and hot air exchange chamber is made of six warming plates.Cold and hot air exchange chamber and extraneous contacting have been completely cut off like this, so that heat interchange and refrigeration are better.
As a kind of preferred version, described air inlet is provided with two, and described air outlet is provided with two.So that air intake and air-out effect are better.
As a kind of preferred version, be provided with drip tray in the bottom of refrigerated dehumidification chamber, the condensation-water drain of described cold and hot air exchange chamber is connected with drip tray.Drip tray is used for collecting condensate water, and damp-heat air runs into the evaporator kapillary that is under the low-temperature condition in the damp-heat air release room, discharge condensate water, and condensate water flows in the drip tray by condensation-water drain.
As a kind of preferred version, described refrigerating plant includes condenser and compressor, and the pipeline that links to each other between described condenser and the compressor is through the top of drip tray, and pipeline becomes U-shaped above being positioned at drip tray.The connecting line of condenser and compressor curves U-shaped through drip tray, and the heat that condenser and compressor produce has just in time been taken away Trace Water Vapor in the drip tray, substantially can guarantee the evaporated condensation water outflow.
As a kind of preferred version, on the through hole on the described dividing plate centrifugal blower is installed.Centrifugal blower discharges in the chamber air with damp-heat air and is extracted into cold dry air and detaches in the chamber.
As a kind of preferred version, be provided with radiator window on the wall of described refrigerated dehumidification chamber, at radiator window cooling fan is installed.The refrigerated dehumidification indoor section at compressor and condenser place is designed to semi-open space, and air permeability and thermal diffusivity are better.
As a kind of preferred version, be provided with the fan that blows to the hardware chamber going out air compartment.Go out air compartment and be designed to full closeding state,, go out air compartment and form negative pressure under the effect of canyon at fan, cold wind is just up pumped naturally, can save like this setting of bottom fan, has played super-silent effect, also provides cost savings simultaneously.
Therefore, advantage of the present invention is that cold and hot air exchange is separated from hardware is indoor, be provided with specially cold and hot air exchange chamber, the hardware chamber is connected by air outlet with cold and hot air exchange chamber, so that cold and hot air exchange is carried out in special seal cavity, guaranteed that the hardware chamber is in the environment of relatively dry low temperature all the time, has solved the possibility of condensation.
