Described radiating subassembly 113 is made of radiating fin core body 1131 and conduction backplate group 1132; Described radiating fin core body, will not be given unnecessary details by general known technology folding forming by fin, but does not especially preferably open the radiating fin of air regulator, and purpose is for guaranteeing the mechanical strength of its fin and radiating subassembly; Be configured with the mechanical strength that is beneficial to the raising radiating subassembly with this, produce distortion in the time of can effectively avoiding stepping up to assemble; Conduction backplate group is made of identical upper and lower conduction backplate 1132a, the 1132b of structure, more than the conduction backplate is an example, any cross section of last conduction backplate becomes the L type, it has side length with the radiating fin core body vertical backplate portion 11321 suitable with width, an end of vertical backplate portion forms the suitable end face backplate portion 11322 of end face length and width with the radiating fin core body, vertically backplate portion is responsible for covering radiating fin core body one side, and end face backplate portion is responsible for covering an end face of radiating fin core body; Last conduction backplate is responsible for covering a side and end face of radiating fin core body, the backplate that conducts electricity down is responsible for covering the another side and the other end of radiating fin core body, the radiating fin core body is interposed in the middle one lead welding and shaping of upper and lower conduction backplate, constitute radiating subassembly, described upper and lower conduction backplate not only is responsible for protection radiating fin core body, also be responsible for the calandria conduct electrical power on the Contact Heating assembly, construct with this and both can make things convenient for the technology assembling, can effectively improve the efficiency of heating surface again;
Further, but the heater of described heat generating component holds the first holding tank 112a that plate 1121 one sides have hold electrodes plate 1111, and the another side that the heater of heat generating component holds plate has the second holding tank 112b that can hold radiating subassembly conduction backplate; The two ends that this heater holds plate 1121 are provided with respectively steps up spring and sets recess 112c, steps up spring down and set recess 112d on the appearance;
Construct thus, the heater that battery lead plate is embedded in heat generating component holds on the plate, and radiating subassembly also is embedded in heater by the conduction backplate to be held on the plate, stack according to this, and combining closely mutually is integral; Several heaters hold the spring that steps up of plate one end and set jaw that steps up spring of recess formation holding, these heaters hold the spring that steps up of the plate other end and set the another jaw that steps up spring of recess formation holding, both guarantee to step up spring and the location assembling of heating core body, also ensured the location assembling of heating core body and upper and lower support;
Add two of stepping up spring step up portion by the first core body backplate, the second core body backplate to the heating core body both sides application of force;
With this, the heating core body can clamp very easily and be assembled into one, and assembly technology is simple, owing to need not the silica gel bonding between each parts, has fundamentally overcome the aging problem of assembly, and is safe and reliable, the useful life and the fail safe that have effectively improved heater;
The heater of described heat generating component holds the length and width size of the first holding tank 112a of plate should be suitable with the length and width size of the battery lead plate 1111 of anode component (or anode component), so that battery lead plate and heater hold firm and hard existing location and installation; The heater of described heat generating component hold plate the second holding tank 112b the length and width size should to conduct electricity the length and width size of backplate suitable with radiating subassembly so that radiating subassembly and heater hold firm and hard existing location and installation;
Further, first, second core body backplate can be set to construct identical; But battery lead plate is identical with the sheet material thickness of radiating subassembly conduction backplate, can be convenient for assembly, also can realize the configuration of parts unified standard, and help optimizing technology, reduce manufacturing cost.
After the preferred embodiment that describes in detail, be familiar with this technology personage and can clearly understand, can carry out various variations and modification not breaking away under following claim and the spirit, and the present invention also is not subject to the execution mode of illustrated embodiment in the specification.
