(5) embodiment
As shown in Figure 1, the utility model comprises outer container 10, interior case 20, radiator fan 30 and heat exchanger 40.Consult Fig. 2 again.Wherein interior case 20 is configured in the outer container 10; Radiator fan 30 is configured in and reaches under the outer container 10 on the interior case 20; Heat exchanger 40 is configured between outer container 10 and the interior case 20, and faces the wall that is connected on interior case 20.
Outer container 10 is provided with door-plate 11, so that the maintenance personal is convenient near the equipment in the case, if the space permission, preferably a left and right sides door-plate 11 is respectively established in front and back, so more helps the maintenance personal near the equipment in the case.
Interior case 20 is main equipment and peripheral auxiliary equipment actual placement part thereof, as signal transmission apparatus, photosignal conversion equipment, space between interior case 20 and the outer container 10 should be as far as possible little, to save the cost of space and outer container, but should keep suitable space and be radiated to interior case 20 via outer container 10 with the radiation heat that reduces sunlight, and provide air flow required space, in order to radiator fan 30 hot-air of inside is discharged.
As shown in Figure 2, the example in being configured in the case 20, this casing adopt two-shipper to set up meter, are respectively one group 21 cun to 23 cun adjustable standard rack and one group 19 cun standard rack.This casing comprises switchboard, power supply unit, connector etc.For keeping in repair the convenience of the equipment in it, case 20 is also established an openable door-plate 21 in this.
The Exposure to Sunlight heat energy that radiator fan 30 is absorbed outer container 10 is got rid of rapidly outside the casing, can utilize the louvre 15 on the pedestal door-plate 14 in pedestal 13 fronts to introduce the lower air of temperature, and be discharged by the louvre 16 of outer container.So, can reduce heat radiation that outer container 10 absorbed to interior case 20.This radiator fan 30 can be selected to be arranged under the strongest area of illumination of amount of sunlight to obtain best radiating efficiency.
Shown in Fig. 3-6, this heat exchanger 40 comprises a shell, and its central interior is provided with a horizontal baffle 47, roughly it is divided into upper and lower two compartments 49,48.Heat exchanger 40 inside mainly comprise bottom fan 41, top fan 42, radiating fin 43, condenser pipe 44.Condenser pipe 44 outer distribution radiating fins 43, condenser pipe 44 are and uprightly vertically are provided with and pass dividing plate 47, and the epimere of condenser pipe 44 and hypomere are laid respectively within the upper and lower compartment 49,48.The principle of work of heat exchanger by: bottom fan 41 is shown in down compartment 48 according to arrow and is caused one air-flow, and this air-flow circulates between following compartment 48 and interior case 20, its temperature because of the heat that heater produces of interior case 20 than the ambient temperature height.The top fan 42 of being located at heat exchanger 40 tops is shown in compartment 49 according to arrow and causes another strand air-flow, and this air-flow circulates between last compartment 49 and temperature-controlled cabinet outside, and its temperature is communicated in outside air, so compartment 48 is low down.
Consult Fig. 3 and Fig. 6 simultaneously, condenser pipe 44 hypomeres in following compartment 48 are by the heat of radiating fin 43 absorption circulations in the air-flow of following compartment 48, and the interior refrigerant of condenser pipe 44 hypomeres evaporates because of heat absorption and be upwards mobile.On the other hand, condenser pipe 44 epimeres in last compartment 49 also are discharged into heat in the air-flow by radiating fin 43, and the refrigerant temperature in condenser pipe 44 epimeres descends, and proportion increases, so flow downward.This one upwards and downward flowing makes refrigerant form natural convection condenser pipe 44 in, thereby improves the efficient of hot biography.
The characteristics of the utility model temperature-controlled cabinet are: this casing has the inside and outside double-deck design, the height that its outer layer box body can effectively stop Exposure to Sunlight and be produced is warm, and utilize radiator fan 30 suitably to discharge heat, in addition, its heat exchanger utilizes fan and radiating fin to make the refrigerant in the condenser pipe produce temperature difference at high and low diverse location, and then causing the proportion difference, therefore refrigerant produces convection current up and down and reaches better heat radiating effect.Find that through experiment when the pyrotoxin of 250 watts (Watt) was arranged in the casing, the temperature difference with environment in the casing can be controlled in below 6 degree Celsius, can meet the operating temperature requirement of most main equipments.
