It is compared in technology, the present invention realizes cooling in such a way that phase transformation is evaporated, and load box need not just be reloading with large-scale air-cooler, load
The volume of case is reduced.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings, but the embodiment in attached drawing is not constituted to any limit of the invention
System, for those of ordinary skill in the art, without creative efforts, can also obtain according to the following drawings
Other attached drawings.
Fig. 1 is the structural schematic diagram of load box of the invention.
Fig. 2 is the circuit block diagram of load box of the invention.
Specific embodiment
The invention will be further described with the following Examples.
See Fig. 1 and Fig. 2, in the present embodiment, the shell of load box is an airtight cabinet 1, is fixed with multi-disc in cabinet 1
High-power resistance piece 3, each equidistantly arrangement of sheet resistance piece 3.
Decafluoropentane 4 is contained in cabinet 1, each sheet resistance piece 3 is all immersed in Decafluoropentane 4.Decafluoropentane 4 is as exhausted
The fluorine carbon medium of edge, form are fluid, can submerge and be filled between each sheet resistance piece 3, and will not make each 3 phase of sheet resistance piece
Mutually short circuit.Further, since the non-combustible fluid that Decafluoropentane 4 is non-toxic and tasteless, staff can directly contact, band carries test process
Middle fluid will not cause spontaneous combustion because of the electric spark on resistor disc 3.
At the top of cabinet 1, one gas outlet 11, the input of gas outlet 11 and the condenser 9 being set to outside cabinet 1 are set
Port connects.One liquid return hole 12 is set at the top of the right side wall of cabinet 1, then by the output port of liquid return hole 12 and condenser 9
Connect.After 4 phase transformation of Decafluoropentane, gaseous 4 emersion liquid level of Decafluoropentane, and condenser 9 is discharged to by gas outlet 11
In, it is cooled in condenser 9 and becomes liquid again, the Decafluoropentane 4 of liquid is flowed back in cabinet 1 by liquid return hole 12, forms circulation.
Band carries in test process, and 3 heating power of resistor disc, heat is absorbed by Decafluoropentane 4, makes the temperature of Decafluoropentane 4
Rise, since the gasification boiling point of Decafluoropentane 4 only has 55 DEG C, Decafluoropentane 4 is easy for reaching boiling point, to undergo phase transition latent
Heat releases amount of heat, and heat is evaporated into gaseous Decafluoropentane 4 and takes away, and realizes the cooling of resistor disc.
Resistor disc 3 during the energization, is commonly present local temperature and steeply rises phenomenon in a short time, if local temperature is super
181 DEG C are crossed, pyrolytic will occur for Decafluoropentane 4.To avoid 4 pyrolytic of Decafluoropentane, load box is stirred configured with more
Machine 2 is mixed, wherein the blade 21 of each blender 2 is evenly distributed on the inner bottom surface and surrounding inner wall of cabinet and is immersed in ten fluorine penta
In alkane 4, the motor of each blender 2 is set on the outside of cabinet, and every blade 21 is connected to corresponding motor by shaft；Then
Controller 7 is set in 1 outer wall of cabinet, each blender 2 is electrically connected controller 7；Then, it is arranged in cabinet 1 multiple
Temperature sensor B, and be distributed in each temperature sensor B near resistor disc 3, then by each temperature sensor B and controller 7
Electrical connection.In this way, when controller 7 detects the detection temperature of any one temperature sensor B higher than setting threshold values, controller
7 just start each blender 2 immediately starts low speed operation, makes 4 thermally equivalent of Decafluoropentane, avoids the temperature of local Decafluoropentane 4
Degree steeply rises in a short time.
Certainly, it can also start always blender 2 during resistor disc 3 is powered and be stirred, and without local temperature
Degree detection.
Further, display 8 not shown in the figure is set in the outer wall of cabinet 1, is arranged in the inner left wall of cabinet 1
Liquid level sensor 6, liquid level sensor 6 and display 8 are electrically connected controller 7, and controller 7 is detected by liquid level sensor 6
When too low to liquid level, control display 8 carries out level alarm and shows, staff is notified to carry out fluid infusion.Since Decafluoropentane 4 is exhausted
Edge, it is static pressure type that liquid level sensor 6, which is selected, by hydraulic conversion at electric signal by way of realize level gauging, therefore energy
Decafluoropentane 4 is measured.The baroceptor 5 to connect with controller 7 is set in the inside top surface of cabinet 1, controller 7 is logical
When crossing baroceptor 5 and detecting 1 air pressure inside of cabinet too low (mean occur gas leakage), passing through display 8, to carry out gas leakage alert
Report, notifies staff to check.Be sticked temperature sensor A at gas outlet 11, and temperature sensor A is also electric with controller 7
Connection, controller 7 pass through the temperature of temperature sensor A real-time detection gaseous state Decafluoropentane 4, adjust condensation in real time according to the temperature
The condensation rate of device 9 makes Decafluoropentane 4 keep disengaging balance.
It should be noted that due to temperature sensor A, temperature sensor B, blender 2, resistor disc 3, baroceptor 5,
Liquid level sensor 6, controller 7, display 8, condenser 9 are the prior art, herein not the internal structure to above-mentioned electric appliance and
Circuit is repeated.
