Further,, when ambient temperature is lower than the unlatching temperature value, processor closing axle flow fan.
Temperature when the external world is lower than this unlatching temperature value, and axial flow blower quits work, energy savings.
Further, axial flow blower can be for more than two.
Further, temperature control equipment comprises the alarm that is electrically connected with processor, the alarming value of processor preset temperature, and when ambient temperature is higher than this alarming value, the alarm signal that gives the alarm.
Further, alarm is the sound and light alarm lamp.
Further, temperature control equipment also comprises the overtemperature trip switch, and the overtemperature trip switch is electrically connected with processor, and with the load end conducting, processor preset the trip temperature value, when ambient temperature reached the trip temperature value, the overtemperature trip switch tripped.
Further, the overtemperature trip switch is contactor or on-load switch.
Simultaneously, a kind of capacitor box that contains the said temperature control device also is provided.
A kind of capacitor box comprises cabinet and said temperature control device, and temperature control equipment is installed in the cabinet.
Further, axial flow blower is located at the top of cabinet.
Further, the bottom of cabinet also is provided with air vent.
The installation shaft flow fan on the cabinet top of capacitor box, and have air vent in the cabinet bottom, cool breeze is from beneath entering, and hot blast is forced to discharge from the cabinet top, lets the air in the capacitor box form convection current.Heat in the very fast capacitor box that leaves has reduced the temperature of electric capacity, prevents that capacitance temperature is too high.

[embodiment]
For the ease of understanding the utility model, will more comprehensively describe the utility model with reference to relevant drawings below.Provided the first-selected embodiment of the utility model in the accompanying drawing.But the utility model can be realized with many different forms, be not limited to embodiment described herein.On the contrary, provide the purpose of these embodiment be make the disclosure of the utility model comprehensively thorough more.
Need to prove, when element is called as " being fixed in " another element, it can be directly on another element or also can have element placed in the middle.When an element is considered to " connection " another element, it can be to be directly connected to another element or possibly to have element placed in the middle simultaneously.Term as used herein " vertical ", " level ", " left side ", " right side " and similar statement do not represent it is unique embodiment just for illustrative purposes.
Only if definition is arranged in addition, the employed all technology of this paper are identical with the implication of the those skilled in the art's common sense that belongs to the utility model with scientific terminology.Among this paper in the instructions of the utility model employed term be not intended to be restriction the utility model just in order to describe the purpose of concrete embodiment.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
See also Fig. 1, temperature control equipment 100 comprises processor 110, temperature sensor 120 and axial flow blower 130.
Temperature sensor 120 is used to gather ambient temperature information, and is electrically connected with processor 110.Temperature sensor 120 sends to processor 110 with the ambient temperature information that collects.
Axial flow blower 130 is electrically connected processor 110.Axial flow blower 130 can be for more than two.In order better to reach radiating effect, in the present embodiment, axial flow blower 130 is the large power shaft flow fan about 40W.
Processor 110 is set one and is opened temperature value, and when ambient temperature was higher than the unlatching temperature value that processor 110 sets, processor 110 sent open command; Make axial flow blower 130 unlatching work; Promote air flow to take away heat, the temperature around reducing prevents that the temperature of electric capacity is too high.When ambient temperature was lower than the unlatching temperature value, processor 110 sent stop signal to axial flow blower 130, and axial flow blower 130 is quit work, and saved the energy.In the present embodiment, axial flow blower 130 is two.
Temperature control equipment also comprises alarm 140.Alarm 140 is electrically connected with processor 110.Be appreciated that alarm 140 is mechanical alarm or electronic alarm, perhaps alarm 140 can omit.In the present embodiment, alarm 140 is the sound and light alarm lamp.
Similarly, processor 110 is set the alarming value of a temperature, and when ambient temperature was higher than alarming value, processor 110 was to alarm 140 order that gives the alarm.Alarm 140 sends alerting signal and reminds the load of operator on duty's closed portion, reduces the load heat radiation, prevents that load from damaging.
Temperature control equipment 100 also comprises overtemperature trip switch 150, and overtemperature trip switch 150 is electrically connected with processor 110, and and load end conducting.Be appreciated that overtemperature trip switch 150 is contactor or on-load switch or omission.In the present embodiment, overtemperature trip switch 150 is a relay.
Similarly; Processor 110 is also set a trip temperature value, and after axial flow blower 130 continuous firings, ambient temperature continues to raise and reach the trip temperature value; Alarm 140 is in alarm condition always, and then processor 110 sends trip signal to overtemperature trip switch 150.150 tripping operations of overtemperature trip switch are broken off load end and supply voltage, and formation is opened circuit, and electric capacity is quit work.By the time temperature drops to when being lower than alarming value, could open the electric capacity that is disconnected, and it is reworked.Stop the electric capacity heat radiation on the one hand and reduce temperature, protect electric capacity on the other hand, prevent to cause circuit to burn, capacitance damage because temperature is too high.
Simultaneously, a kind of capacitor box (figure does not show) that contains said temperature control device 100 also is provided.
