This electric heater unit 17 can be in single district heater 1, that is, make the heating of whole passenger compartment feasible, or be in multizone heater 1, think multiple zones of different heating of passenger compartment, such as, driver side and passenger side are separated, or the demist of footwell and heating are separated.
For this reason, separator can be provided with in heater 1, this separator be arranged as such as substantially in the centre of framework 21 and the longitudinal side being parallel to framework 21 in the level of axis A1 extend, and another separator may be provided with, this another separator be arranged as such as substantially in the centre of framework 21 and the cross side being parallel to framework 21 in the level of axis A2 extend, so that framework 21 is divided into four different pieces, such as: front left, front right, rear left and right, for the zones of different be associated of the correspondence of passenger compartment heats.
Air stream is disposed in the shell 29 of framework 21 thus air stream to be heated heats through their heater module 27, these shells 29 are defined by longitudinal wall of framework 21 in the example shown and can be inserted between the through region 30 of framework 21, to adjust air stream.
Gross calorific value needed for the quantity basis of heater module 27 is determined, this depends on application.These heater modules 27 are arranged as and are parallel to each other and extend in the mode be directly exposed to through the air stream of unit heater 19 in the whole length of the framework 21 of unit heater 19.
In addition, heater module 27 can comprise positive temperature coefficient (PTC) type resistive element.These elements are protected avoids superheated and overcurrent.
In variant in figure 3, heater module 27 comprises two longitudinal electrodes 31, each longitudinal electrode 31 separately around heat dissipation device 33, described heat dissipation device 33 such as by bending or corrugated metal band formed and carry against PTC resistive element or stone 35.In order to clearly, heat dissipation device 33 does not have complete illustrating in figure 3.Certainly, heat dissipation device 33 extends in the whole length of electrode 31.
In another variant (not shown) of heater module 27, electrode clamping resistive element, and the heat dissipation device formed by metal band is arranged as the free exterior face against described electrode.In other words, heater module 27 is made up of two heat dissipation devices, and described two heat dissipation devices, around two electrodes, are furnished with PTC stone or resistive element between described two electrodes.
Two electrodes 31 of heater module 27 are connected to different electromotive force by two the first electric terminals 37, such as, in vehicle available the first electromotive force (such as cell voltage) and the second electromotive force of such as earthing member.
In example in fig. 2, if be provided with three heater modules 27, then row six terminals 37 are had to be supplied with electric energy.
With reference to figure 2,4 and 5, it is seen that framework 21 comprises device for guiding and possibly for heater module 27 being remained on the device in the shell 29 of framework 21.
With reference to guide device, framework 21 comprises multiple guiding flank 39 on its air intake face A and its air outlet slit face B, such as be roughly X-shaped shape, along the direction orientation tilted relative to the direction of insertion D of heater module in the shell 29 of framework 21, as indicated by the arrow, such as, with the angle of 2 ° to 88 °.
This kind of orientation is convenient to the guide heaters module 27 when heater module 27 is inserted in framework 21.
In addition, these guide flanks 39 also to provide the structural strengthening of framework 21, the pliability of limiting frame 21 the machinery performance hence improved in the torsion of framework 21.In the level that can be arranged on shell 9 perpendicular to the additional rib portion 41 of direction of insertion D and/or through region 30 place, for the local strengthening of framework 21.
What flank 39 can be arranged in the shell 29 of framework 21 is arranged in the either side of the pass-through zone 30 of framework 21 on the either side receiving heater module 27.When heater module 27 is inserted in the shell 29 of framework 21, move along flank 39 in the level of shell 29 with the contact point of heater module 27.
On the air intake face A that flank 39 equally alternately can be arranged in framework 21 and on the B of air outlet slit face.More accurately, if the first flank 39 is arranged on the A of air intake face, then next flank is arranged on the B of air outlet slit face.In this case, the flank 39 on two relative face A, B is not aspectant, but is biased in the mode making heat loss balance.
To notice, framework 21 and flank 39 form single one-piece parts, and it is manufactured by moulding of plastics materials.
Therefore, when heater module 27 to be inserted in along direction of insertion D from the left side Fig. 2 and 4 in the shell 29 be associated of framework 21, heater module 27 is guided along shell 29 constantly by continuous print flank 39.
For this reason, two distance d in succession between flank 39, the more accurately last contact point P of the first flank 39 and the heater module 27 be inserted into
1with the first contact point P of next the second flank 39
2between distance d calculated, to ensure the lasting guiding of described heater module 27 during the insertion of heater module 27.
In addition, flank 39 can be arranged about in the axis of symmetry A1 and A2 of framework 21 or both substantially symmetrically in the mode of balanced top/bottom and/or left/right heat loss.
Paying particular attention to, does not align on the same axis in the crosspoint of three X-shaped flanks 39 in succession, thus these crosspoints are relative to each other biased along the direction (that is, along direction A2) perpendicular to the incoming direction D of heater module 27.
Also will notice, one or more crosspoints of X-shaped flank 39 be arranged in define shell 29 edge on, that is, and wall (it is the border between shell and adjacent through region 30) conllinear.This is by by stacked for another structural detail of itself and framework and limit the negative effect to heat loss that such intersection may cause.
In an identical manner, one or more crosspoints of X-shaped flank 39 are arranged as and the PTC stone of heater module 27 or resistive element conllinear.
Framework 21 can comprise other the additional device for guide heaters module 27, such as on the wall of shell 29 towards one or more protuberances 43 that the inside of shell 29 extends.
For the device for being remained on by heater module 27 in framework 21, framework 21 can comprise flexible hook portion 45, and described flexible hook portion 45 is essentially S shape, such as, be used as the flexible base against the end of heater module 27.
Framework 21 may further include flexible strip 47, and described flexible strip 47 is for being applied to heater module 27 by frictional force.For this reason, the direction D that reed 47 and heater module 27 are inserted into shell 29 becomes non-zero angle.
In addition, framework 21 can be fixed, such as, be snapped into module 23, and can comprise buckle sheath 51 for this reason, and the complementary snap features 53 that module 23 supports is inserted in described buckle sheath 51.
With regard to control module 23 itself, the material manufacture can bearing the high temperature reached in the operation of heater 17 of this control module 23, and can be formed by the module body 23a be fixed together and lid 23b, be such as fastened togather by buckle device 54.
In addition, module 23 comprises supply of electric power circuit, on the support member that this supply of electric power circuit is arranged on such as printed circuit board (PCB) and be also known as bus by two metallic conductors 55 and 55'() be connected to power supply, wherein the first conductor 55 can be in the first electromotive force, and the second conductor 55' can be in the second electromotive force.Such as, supply of electric power circuit comprises electron transistor (not shown), for allowing or the flowing of block current flow in heater module 27.
In addition, when related transistor allows current flowing, be connected to conductor 55, terminal 37 that the terminal 57 of 55' conveys electrical current to heater module 27.Comprise in the example of three heater modules 27 showing electric heater unit 17, six terminals 57 are set to six terminals 37 of the correspondence for supplying power to heater module 27.For this reason, terminal 37 and 57 is connected, and such as soldered or crimping connects, and when crimping connects, crimping point 59 manufactures by connecting.
In addition, supply of electric power circuit can receive information about the electric power that will be delivered via connector 61.
In addition, the heat loss caused in order to the opening (air stream to be heated is through described opening) compensated needed for the connection of terminal 37 and 57 is uneven, the heel 25 contrary with module 23 can be that the heat loss comprising opening 63 balances root, and described opening 63 is designed to make air stream to be heated through them.
It is therefore clear that, the structure of framework 21 and flank 39 both for guide heaters module during being inserted into framework 21 at heater module also for structurally reinforced frame, this structure makes the assembling of heater 17 convenient, and the degeneration that the excessive pliability avoiding heater module 27 can be held as heated the framework 21 of device module 27 in addition causes.
