[embodiment]
In order to make, object of the present invention, technical scheme and useful technique effect are more clear to be understood, below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.Should be understood that, the embodiment of describing in this specification is only used to explain the present invention, is not in order to limit the present invention.
Please refer to shown in Fig. 1 to 2, a kind of electronic intelligence battery case 100, it comprises casing and is fastened on the lid (not shown) on casing, described casing comprises substrate 10 and from the upwardly extending sidewall 11 of substrate surrounding, the sidewall 11 of aforementioned surrounding encloses in the receiving space of formation refrigerating plant is also installed, and described refrigerating plant comprises power supply (DC24V), some cooling pieces 21, processes temperature signal module 22, relay 23 and temperature sensor 24.Aforementioned temperature signal processing module 22, relay 23 and cooling piece 21 series connection, described temperature sensor 24 is connected in parallel with processes temperature signal module 22, has so just formed a control circuit.Some cooling pieces 21 are connected in parallel, and each cooling piece 21 is provided with refrigeration end and heating end, and the heating end of aforementioned two adjacent cooling pieces links together by heat-conductive bridges 30, and an epitaxial lateral overgrowth of described heat-conductive bridges 30 is stretched on the sidewall 11 that is connected to casing.Specifically, described heat-conductive bridges 30 is orthogonal bulk roughly, its two ends are connected to refrigeration end and the heating end of cooling piece, at an epitaxial lateral overgrowth of the substantial middle position of described heat-conductive bridges, stretch and form the link 31 that another rectangular block shape is connected with battery case sidewall.
The casing of battery case generally adopts metal material to make, and therefore, above-mentioned heat-conductive bridges 30 just can be dispelled the heat by the sidewall of battery case casing after the heat of the heating end of cooling piece is derived.Yet, in the actual use procedure of battery case, tend to find that the radiating rate of wall box 11 of common battery case is limited.For more convenient release heat, the sidewall of the casing of electronic intelligence battery case of the present invention has adopted more specifically design concept, and specifically, at least one sidewall 12 of described casing or the part outer surface of a sidewall are processed to the sheet of dispelling the heat.Because the surface area of sidewall of heat radiation sheet is excessive with respect to common sidewall, therefore, the heat producing in battery pack work more easily leaves.
Impact for fear of the high temperature in the battery case external world on battery pack normal operation, the present invention is also by the sidewall 12 except the sheet that is made into dispel the heat, at least also have a sidewall to be provided with thermal insulation layer, the receiving space that the setting of thermal insulation layer just can enclose battery case sidewall like this forms a separate space of transmitting with extraneous inefficient heat.
The heat that electronic intelligence battery case of the present invention produces in the course of the work in order to discharge better battery pack, guarantee that battery pack is discharging and recharging under operational environment reliably, selected the metallic copper with good heat conductive performance to make heat-conductive bridges, and the outer surface of battery case casing substrate has been processed into heat radiation sheet.
The course of work of electronic intelligence battery case of the present invention is achieved in that when initial, battery pack in battery case is started working, when work is after the regular hour, when the heat that battery pack discharges accumulates gradually to the temperature of setting, temperature sensor 24 real-time monitors the problem in battery case, and temperature information is transferred to processes temperature signal module 22, processes temperature signal module 22 relatively decides the break-make of relay 23 mutually according to the temperature detecting and the temperature of setting, thereby controls the operating state of cooling piece 21.
What the power acquisition of the refrigerating plant of electronic intelligence battery case of the present invention was used is 24V DC power supply, can directly power taking in battery pack, adopted semiconductor chilling plate, and realized the high feature of refrigerating efficiency.In addition, Battery case is totally enclosed type, can avoid dust, rainwater to enter, and has alleviated pressure to follow-up maintenance.
Electronic intelligence battery case of the present invention, be not restricted to described in specification and execution mode, therefore for the personnel of familiar field, can easily realize additional advantage and modification, therefore in the situation that do not deviate from the spirit and scope of the universal that claim and equivalency range limit, the present invention is not limited to specific details, representational equipment and illustrates here and the examples shown of describing.
