[background technology]
Battery in the current notebook computer is to adopt lithium battery mostly, because lithium is the very active element of a kind of chemical, and when accidental short circuit, bump occurring, easily on fire, blast.The incident that battery in the notebook computer sets off an explosion is more and more, makes user's life safety and property be subjected to great loss.Although occurred a variety of battery protection measures at present; but this class safeguard measure is to cut off the electricity supply when battery is short-circuited mostly; high temperataure phenomena is not solved; temperature in the notebook computer still can set off an explosion when too high, thereby can not effectively protect to play the measure of exploding of preventing.
[summary of the invention]
Main purpose of the present invention is to provide a kind of explosion protection for batteries of effectively protecting and battery anti-explosion method.
For reaching above purpose, the invention provides a kind of explosion protection for batteries, it is applicable in the explosive type electronic installation, wherein, is provided with a battery in this explosive type electronic installation; And this explosion protection for batteries comprises: a temperature-sensitive sticker, and it is in order to the temperature signal around the sensing battery and convert this temperature signal to the signal of telecommunication; This temperature-sensitive sticker control circuit that is coupled, and this control circuit is in order to receiving this signal of telecommunication, and will compare processing between this signal of telecommunication and the set point, and when this signal of telecommunication exceeds this set point, send a drive signal; This control circuit electrically operated valve that is coupled, and this electrically operated valve is in order to receiving this drive signal, and the action of opening according to this drive signal; This electrically operated valve is located at the liberation port place of a chiller, and stores refrigerant in this chiller, and when electrically operated valve was unlatching, refrigerant can outwards discharge and absorb a large amount of heats from liberation port.
The present invention also provides a kind of battery anti-explosion method, and to reach, wherein, this explosion protection for batteries comprises a temperature-sensitive sticker, a control circuit, an electrically operated valve and a chiller to this battery anti-explosion method by above-mentioned explosion protection for batteries.And this battery anti-explosion method may further comprise the steps: the temperature signal around the temperature-sensitive sticker sensing battery also converts this temperature signal to the signal of telecommunication; Control circuit receives the signal of telecommunication, and judges whether the signal of telecommunication exceeds a set point, and when exceeding, sends a drive signal; Electrically operated valve receives this drive signal, and the action of opening according to this drive signal; Discharge refrigerant in the chiller, absorb a large amount of heats simultaneously.
Compared to prior art; (burn soon, the explosion time) processing of in time lowering the temperature that can meet accident at battery of explosion protection for batteries of the present invention and battery anti-explosion method; avoid the generation of exploding, user's life safety is effectively protected, and makes user's loss drop to minimum.

Fig. 2 is the flow chart of battery anti-explosion method of the present invention.
[embodiment]
See also shown in Figure 1ly, explosion protection for batteries of the present invention is applicable to that this explosive type electronic installation can be a notebook computer in the explosive type electronic installation (figure do not show), is provided with a battery (figure does not show) in this explosive type electronic installation, and this battery can be a lithium battery; And this explosion protection for batteries comprises a temperature-sensitive sticker 10, and this temperature-sensitive sticker 10 also converts this temperature signal to the signal of telecommunication in order to the temperature signal (temperature signal can be the size of Current Temperatures, or is the rate of change of Current Temperatures) around the sensing battery; This temperature-sensitive sticker 10 couplings one control circuit 20, and this control circuit 20 is in order to receiving this signal of telecommunication, and will compare processing between this signal of telecommunication and the set point, and when this signal of telecommunication exceeds this set point, send a drive signal; This control circuit 20 couplings one electrically operated valve 30, and this electrically operated valve 30 is in order to receiving this drive signal, and the action of opening according to this drive signal; This electrically operated valve 30 is located at the liberation port place of a chiller 40, and stores refrigerant in this chiller 40, and in present embodiment, this refrigerant is solid carbon dioxide.When electrically operated valve 30 was unlatching, refrigerant can outwards discharge and absorb a large amount of heats from liberation port.
Please in conjunction with consulting Figure 1 and Figure 2, to reach, wherein, this explosion protection for batteries comprises a temperature-sensitive sticker 10, a control circuit 20, an electrically operated valve 30 and a chiller 40 to battery anti-explosion method of the present invention by an explosion protection for batteries; And this method may further comprise the steps:
Step 201: the temperature signal around the temperature-sensitive sticker 10 sensing batteries also converts this temperature signal to the signal of telecommunication;
Step 202: control circuit 20 receives the signal of telecommunication, and judges whether the signal of telecommunication exceeds a set point, and when exceeding, sends a drive signal; If when not exceeding, then return step 201;
Step 203: electrically operated valve 30 receives these drive signals, and the action of opening according to this drive signal;
Step 204: discharge refrigerant in the chiller 40, absorb a large amount of heats simultaneously.Refrigerant in distillation (for example; solid carbon dioxide is from the solid-state gaseous state that changes into) process need to absorb a large amount of heats, make that the temperature around the battery descends rapidly, thereby avoid the generation of exploding; user's life safety is effectively protected, and makes user's loss drop to minimum.
