Regulating valve 32 is used to adjust the flow of coolant liquid in inlet pipe 30, the i.e. flow of the coolant liquid of inflow recirculating zone 103；Return liquid temperature
It spends sensor 41 to be arranged on liquid back pipe road 40, for monitoring the temperature of coolant liquid in liquid back pipe road 40；Control system with it is above-mentioned
Feed liquor temperature sensor 31, feed liquor flow control valve 32 and time 41 signal of liquid temperature sensor connection, control device are used for root
The aperture that feed liquor flow control valve is adjusted according to feed liquor temperature sensor and the temperature difference returned between liquid temperature sensor, specifically, working as
When the total calorific value of electronic equipment increases, the temperature of coolant liquid will be increased in liquid back pipe road 40, and work as feed liquor temperature sensor 31
When being greater than the set value with the temperature difference returned between liquid temperature sensor 41, control device will adjust opening for feed liquor flow control valve 32
Degree increases the flow into the coolant liquid of recirculating zone 103, this increased part cryogenic liquid, which will enter cabinet body 10, joins
With heat exchange, so that the temperature of electronic equipment be made to be maintained in appropriate range；Conversely, the total calorific value when electronic equipment is reduced
When, the temperature of coolant liquid will reduce in liquid back pipe road 40, and when feed liquor temperature sensor 31 and return between liquid temperature sensor 41
Temperature difference when being less than setting value, control device will adjust the aperture of feed liquor flow control valve 32, make the cooling into recirculating zone 13
The flow of liquid reduces.In short, control system can be according to feed liquor temperature sensor 31 and the temperature difference tune for returning liquid temperature sensor 41
Section enters the coolant rate in cabinet body 10, and the calorific value that the flow of coolant liquid can be made total with electronic equipment is mutually fitted
It answers.
When the coolant rate for entering cabinet body 10 changes, overflow from 102 top liquid level of electronic equipment settlement
The flow of the coolant liquid flowed in overflow area 101 can also change therewith.In order to make the liquid level in overflow area 101 remain at one
In a suitable range, which further includes liquid level sensor 90 and returns liquid stream adjustable valve 42, and liquid level passes
Sensor 90 is arranged in overflow area 101, for monitoring the liquid level of coolant liquid in overflow area 101；Return liquid stream adjustable valve 42
It is arranged on liquid back pipe road 40, for adjusting the flow of coolant liquid in liquid back pipe road 40, i.e., the coolant liquid flowed out from overflow area 101
Flow；Control system is connect with above-mentioned liquid level sensor 90 and time liquid stream adjustable valve 42, for according to liquid level sensor
The liquid level of 90 displays adjusts back the aperture of liquid stream adjustable valve 42.Specifically, when the coolant liquid into cabinet body 10
When flow increases, the coolant liquid overflowed in overflow area 101 increases therewith, and liquid level increases in overflow area 101, works as liquid level sensor
When the liquid level of 90 displays is greater than upper limit value, the aperture of liquid stream adjustable valve 42 is adjusted back by control device, is made from overflow
The flow for the coolant liquid that area 101 is flowed out increases, so that excessive coolant liquid be made to flow out overflow area 101 in time；Conversely, when entering machine
When the flow of the coolant liquid of cabinet ontology 10 is reduced, the coolant liquid overflowed in overflow area 101 is reduced therewith, liquid in overflow area 101
Face reduces, and when the liquid level that liquid level sensor 90 is shown is less than lower limit value, adjusts back flow quantity by control device and adjusts
The aperture of valve 42 reduces the flow of the coolant liquid flowed out from overflow area 101, guarantees that the liquid level in overflow area 101 remains
In a suitable range.
When the total calorific value of 10 inner electronic equipment of cabinet body tends towards stability, feed liquor flow control valve 32 and time flow quantity
The aperture of regulating valve 42 will also tend towards stability, into the coolant rate of cabinet body 10 and the coolant liquid of outflow cabinet body 10
Flow reaches unanimity, and 10 cooling system of cabinet body reaches stable state.
In addition, when the liquid submersion cooling machine cabinet operation irregularity, may result in liquid level in overflow area 101 it is excessively high or
It is too low, in order to find failure in time and be handled, low liquid level switch can also be set in overflow area 101 and high liquid level is opened
It closes, low liquid level switch is for monitoring the alarm point of the low liquid level in overflow area 101, if the liquid level in overflow area 101 reaches low liquid level
Point is alerted, then alert；High level switch is used to monitor the high liquid level alarm point in overflow area 101, if overflow area 101
Interior liquid level reaches high liquid level alarm point, then alert.
By above description as can be seen that the liquid submersion cooling machine cabinet optimizes cabinet body 10 by the way that partition is arranged
The runner of interior coolant liquid has carried out effective tissue and adjusting to the flowing of coolant liquid, has improved the cycle efficieny of coolant liquid, into
And improve the cooling effect of electronic equipment；Meanwhile the revolving speed by adjusting propeller 20 makes the flow and separate unit of coolant liquid
