Abstract
The invention provides a water-cooling cabinet temperature keeping regulation and control method capable of improving noise and condensed water and belongs to the field of computer communication. According to the invention, heat conduction and thermal convection are used as theoretical supporting points and keeping of a temperature inside a water-cooling cabinet is carried out by controlling a wind flow rate and a water flow rate, so that a heat dissipation effect is implemented and the problems of the noise and the condensed water are improved. According to the invention, automatic regulation on a power consumption load of the water-cooling cabinet can be conveniently carried out; not only is the requirement on heat dissipation of the water-cooling cabinet implemented, but also the problems of the noise and the condensed water are improved; heat dissipation power consumption of the cabinet is improved; PUE (Power Usage Effectiveness) of a computer room is reduced; and utilization efficiency of energy is improved.
Description
Technical field
The present invention relates to computer communication field, specifically utilize a kind of temperature to keep the method for heat radiation regulation and control, the problem that while solving water-cooled cabinet low-power consumption load, noise and condensate water produce.
Background technology
In order to reduce server radiating power consumption, current server product, starts to occur the design of complete machine cabinet heat radiation; And high-end customer has the demand of water-cooled cabinet application.Water-cooled cabinet is generally used for high power density product radiating requirements, and therefore Single Cabinet need to meet radiating requirements more than 40kw, for meeting this design requirement, need to select high performance fans, and guarantees that chilled water has a lower inflow temperature.
The load of part water-cooled cabinet is lower in actual applications, and water-cooled cabinet refrigerating capacity, as abundant startup, can cause inner supercooling, thereby brings the generation of high noisy and a large amount of condensate waters, and the power consumption that causes dispelling the heat is too high, affects the PUE level of machine room.
Summary of the invention
The object of this invention is to provide the design of a kind of refrigeration of the water-cooled cabinet for different loads situation and heat radiation regulate and control method, the method can effectively be improved noise and the condensate water problem under low load condition.
The present invention is take hot conduction and heat loss through convection as theory support point, thereby the maintenance of carrying out water-cooled cabinet internal temperature by the control of wind flow and discharge realizes radiating effect and improves noise and condensate water problem, concrete summary of the invention can be divided into following three aspects:
A) the enough reference quantities for guaranteeing that regulation and control are used, we are three temp probes of each placement before and after water-cooled coil pipe, utilize reading mean value for judging EAT and the leaving air temp of the refrigeration system of flowing through, and reduce test error, for waterway pipe design Inlet and outlet water temp probe and threeway regulating device, by the crawl of above device information, judge water-cooled cabinet refrigeration work state in addition;
B) utilize discharge in T-valve regulation coil pipe, and then control water flow temperature, avoid lower water temperature to cause the generation of a large amount of condensate waters; By regulating rotation speed of the fan to change the aqueous cold plate manage-style amount of flowing through, by changing heat transfer coefficient, change coil pipe refrigeration performance.
C) utilize leaving water temperature and leaving air temp to regulate and control reference quantity as water-cooled cabinet, leaving water temperature and leaving air temp are all set to a fixed temperature point.When leaving water temperature is higher than water temperature set point, improve T-valve aperture, leaving water temperature, lower than water temperature set point, reduces T-valve aperture; Leaving air temp is higher than wind-warm syndrome set point, improve rotation speed of the fan, leaving air temp is lower than wind-warm syndrome set point, reduce rotation speed of the fan, because of water-cooled cabinet water temperature and wind-warm syndrome variation and actual loading Horizontal correlation, therefore can utilize these control methods to complete fan and discharge control for load level, and then reduce rack noise and condensate water generation.
The invention has the beneficial effects as follows:
By the control of different components state, can effectively change water temperature and wind-warm syndrome, be applicable to the regulation and control of water-cooling system; Can effectively leaving water temperature and leaving air temp be controlled near a fixed value, make water-cooled cabinet effectively adapt to the refrigeration work of different power consumption load, and effectively improve noise problem and condensate water generation; Can easily carry out the automatic adjusting of water-cooled cabinet power consumption load, not only realize the requirement of water-cooled cabinet heat radiation, and improved noise and condensate water problem, improve cooling machine cabinet power consumption, reduce machine room PUE, improve efficiency of energy utilization.
Accompanying drawing explanation
Accompanying drawing 1 is measurement procedure figure of the present invention.
Embodiment
With reference to the accompanying drawings, content of the present invention is described to its implementation and the course of work with instantiation.
Content of the present invention is carried out to more detailed elaboration below:
D) interior of equipment cabinet is installed six air themperature probes and two cooling-water temperature sensors, and three-way control valve is installed in water route, for rack duty, surveys;
E) survey air inlet/outlet temperature and Inlet and outlet water temperature, for calculating, judge water-cooled cabinet operating load and the control of water-cooled cabinet actual working state.
F) by leaving water temperature and leaving air temp and the contrast of systemic presupposition temperature value, according to both differences, carry out the control of water route and air flow field, avoid the too low and too high problem of rotation speed of the fan of water temperature, thereby meet in water-cooled cabinet, under server heat dissipating state, improve noise level and condensate water problem.
Through detailed above design, we can easily carry out the automatic adjusting of water-cooled cabinet power consumption load, have not only realized the requirement of water-cooled cabinet heat radiation, and noise and condensate water problem have been improved, improve cooling machine cabinet power consumption, reduce machine room PUE, improve efficiency of energy utilization.
