In the present embodiment, in conjunction with Fig. 1, two electronic devices in rack are described the different heat dissipation capacity in the situation that, the surface temperature of electronic device A is higher than normal range of operation value, and the surface temperature of electronic device B is in the scope of normal range of operation value.
In the time connecting the startup power supply of electronic device A in rack and electronic device B, control part 10 is controlled starting fan unit 52 and is started, thereby fan 51 is activated.Electronic device A is activated rear running, after electronic device A running, produces heat, and the temperature in electronic device A surface and rack is raise.
Device temperature inductor 311 senses that the air themperature in rack is 45 DEG C so, device temperature is 45 DEG C of numerical signals 45 that are converted to device temperature through device temperature AD converter, and numerical signal 45 is stored this numerical signal 45 by storage part 8 after being gathered by device temperature collecting unit 721.The normal temperature range value that comparing section 9 logarithm value signals 45 and configuration part 6 are set be not more than 40 compare after, obtaining device difference is 5.Control part 10 is controlled refrigeration switching module according to device difference 5 and is started, thereby refrigeration module is activated.
Because continuing running, electronic device A produces more heat, device temperature inductor 311 senses that the surface temperature of electronic device A is 55 DEG C, the signal that surface temperature is 55 DEG C is converted to numerical signal 55 through device temperature AD converter 312, and numerical signal 55 is stored this numerical signal 55 by storage part 8 after being gathered by device temperature collecting unit 721.The normal temperature range value that comparing section 9 logarithm value signals 55 and configuration part 6 are set is not more than 40 and compares, and obtains device difference 15.Device difference 15 obtains analog signal through DA transducer 313a and is loaded into stepper 313b above, and stepper 313b angle of rotation increases the opening increasing that drives electric expansion valve 313c, thereby the flow of cold Guan Zhongleng liquid strengthens.The logical supercooled liquid import 314b of cold liquid enters the cold liquid passage 314a of cold drawing 314, and the cold of cold liquid is discharged by the aperture of cold drawing.Cold drawing 314, by the stent support of 2 millimeters thick, is suspension type and is arranged on electronic device A above, and have gap between electronic device A.Cold liquid carries out endothermic process in cold liquid passage 314a, and then logical supercooled liquid outlet 314c outflow cold drawing 314 returns in refrigeration module 1.The flow that the surface temperature of electronic device A increases cold liquid in corresponding cold drawing 314 strengthens.
In the time that device temperature inductor 321 senses that the surface temperature of electronic device B is 39 DEG C, 39 DEG C of signals of surface temperature are converted to numerical signal 39 through device temperature AD converter 322, and numerical signal 39 is stored this numerical signal 39 by storage part 8 after being gathered by device temperature collecting unit 722.The normal temperature range value that comparing section 9 logarithm value signals 39 and configuration part 6 are set is not more than 40 and compares, and obtains numerical signal 39 within normal temperature range value is not more than 40 scopes.Stepper 323b does not regulate electric expansion valve 323c opening, and electric expansion valve 323c keeps closing cold tubulose state, so that cold liquid does not flow in cold drawing 324.Thereby radiating module 32 does not dispel the heat to electronic device B.
In the time that electronic device A and electronic device B are stopped, air themperature inductor 41 is responded to 40 DEG C of the interior air themperatures of rack, 40 DEG C of signals of air themperature obtain air themperature value 40 through air themperature AD converter, and air themperature value 40 is stored this air themperature value 40 by storage part 8 after being gathered by air themperature collecting unit 71.Control part 10 judges that air themperature value 40 is within normal temperature range value is not more than 40 scopes, and control part 10 is controlled refrigeration switching module and closed, thereby refrigeration module 1 is closed.Now fan 51 continues to electronic device A and electronic device B blowing, it is 35 DEG C when air gas temperature inductor 41 senses air themperature, 35 DEG C of signals of air themperature obtain air themperature value 35 through air themperature AD converter 42, and air themperature value 35 is stored this air themperature value 35 by storage part 8 after being gathered by air themperature collecting unit 71.Control part 10 judges that fan that air themperature value 35 is set in configuration part 6 cuts out value range and be not more than in 35 scopes, and control part 10 is controlled fan closing unit 53 and closed, thereby fan 51 is closed.

According to radiator involved in the present invention, control respectively on different electronic devices the cold flow quantity of cold drawing in radiating module by least one radiating module and control part, realize the man-to-man heat radiation of different electronic devices.By adopting device temperature inductor to sense that the temperature on electronic device surface and the normal temperature range value of configuration part setting are through relatively obtaining device temperature difference, control part is controlled the cold flow quantity of cold drawing in radiating module according to device temperature difference, thereby realize, the electronic device of different heat degree is dispelled the heat, simultaneously energy savings.By refrigeration module, flow controlling unit are arranged on outside rack, the vibrations that refrigeration module produces can not produce vibrations to the electronic device in rack and damage, and are convenient to refrigeration module and flow controlling unit to carry out installation and maintenance.Fan continues, to rack blowing, so can avoid the frosting of cold drawing dewfall after refrigeration module is closed.
Stepping motor in flow controlling unit in the present embodiment and electric expansion valve combination, thus stepper regulates the openings of sizes of electric expansion valve to control cold flow quantity according to difference analog signal.
Refrigeration module in the present embodiment, flow controlling unit are arranged on outside rack, and the vibrations that refrigeration module produces can not produce vibrations to the electronic device in rack and damage, and are convenient to refrigeration module and flow controlling unit to carry out installation and maintenance.Fan continues rack to dry after refrigeration module is closed.
Support is in the present embodiment used for supporting cold drawing, makes between cold drawing and electronic device gappedly, combines use can prevent that refrigeration module from closing rear electronic device surface sweating and frosting with fan.
Above-mentioned execution mode is preferred case of the present invention, is not used for limiting the scope of the invention.
Comparing section is also not only limited to the PID controller in preferred case, also can adopt other as nerve network controller.
