The specific embodiment
[22] Fig. 1,2 partly illustrates one according to the air heating apparatus that is used for the automobile seating accommodation of the present invention.
[23] heating arrangement comprises a housing 10 that limits the pipeline 12 of air to be heated.An air-liquid-type H Exch 14 and an electric heater unit 16 are installed in series in pipeline 12.Electric heater unit 16 is installed in the downstream of H Exch 14 along air-flow direction (arrow F1).As what known, produce by a conveyer (not shown) through the windstream of piping, and the outlet (not shown) that passes the electric heater unit downstream is discharged in the seating accommodation of automobile in the H Exch upstream.
[24] usually, the refrigerant fluid with automotive engine offers H Exch 14.H Exch is arranged in housing 10, for example in the mode of a drawer, and occupies the whole square-section of pipeline 12 in the installation place.
[25] electric heater unit 16 can use basic unmodified heating resistor of resistance or CTP resistance.
[26] electric heater unit 16 is installed respectively with H Exch, separates with H Exch, and occupies the whole square-section of pipeline 12 in the installation place.
[27] compare with the layout that electric heater unit links together on the whole cross section of pipeline with H Exch, because electric heater unit occupies the entire cross section of pipeline, the spacing of it and H Exch can limit the loss owing to the venting pressure that exists electric heater unit to cause in the pipeline.
[28] mostly be 5% most for the minimizing with venting pressure loss, the charge air that promptly causes owing to the existence of electric heater unit is restricted to, should between the upstream face 16a of the downstream face 14b of H Exch 14 and electric heater unit 16, a minor increment be set.In addition, the aeration resistance of electric heater unit should be minimum.
[29] H Exch 14 and electric heater unit 16 can be installed parallel to each other, and promptly their surperficial 14b and 16a are parallel to each other; Perhaps not parallel installation promptly forms a non-vanishing angle between their surperficial 14b and the 16a.
[30] in an example shown, surperficial 14b and 16a are not parallel.Pipeline 12 is not a straight line in the downstream of H Exch 14, and cross-sectional plane successively decreases.The upper limb of electric heater unit 16 can be near the upper limb of H Exch 14, and its lower edge is away from the lower edge of H Exch.
[31] area that occupies less than H Exch of the area that occupies of electric heater unit.Can limit cost like this, particularly when the resistance that uses during as CTP resistance, the composed component of this resistance or the price is rather stiff of stone material.
[32] still, in order to guarantee effective heating of air, the area that electric heater unit provides should be too not little.Therefore electric heater unit not necessarily is in the direction that the air-flow direction of installation place is orthogonal in pipeline with it.
[33] when surperficial 14b and 16a were not parallel, the minor increment that needs between these two surfaces to meet was a mean distance.
[34] applicant is verified, and when the distance between surperficial 14b and the 16a or mean distance during more than or equal to 5 millimeters, the venting pressure loss may be limited to one 5% maxim.For most of devices, this distance is preferably 9 millimeter.
[35] in this case, the restriction of venting pressure loss is owing to do not have aerodynamical mutual action between two elements.
[36] on the other hand, in order to improve the energy efficiency of system, it is necessary that H Exch separates with electric heater unit.
[37] installation of electric heater unit 16 makes that flow air stream all passes electric heater unit 16 in pipeline 12.Therefore, (coefficient d ' adaptation) no better than 100% for the accommodation coefficient of electric heater unit.
[38] for this reason, electric heater unit 16 is placed in the framework, this framework does not have the gap or almost seamlessly cooperates with the pipeline 12 of housing.
[39] especially as Figure 1-3, the framework of electric heater unit has and the protruding 12a of pipeline 12 inwalls, type bar 20a, the 20b that 12b matches along two opposed edges at least, so that realize almost leak free assembling.
[40] cross section of type bar 20a, 20b is the outside U-shaped of opening. Projection 12a, 12b are the fins of some end protuberances, and these fins are arranged in U-shaped type bar.
[41] electric heater unit can be installed in the mode of drawer in the housing 10, and type bar 20a, 20b and protruding 12a, 12b constitute guiding device.
[42] framework of electric heater unit 16 has frame element 22a, 22b (Fig. 2) along two other relative limit.During installation frame, enter on fin 12a, the 12b in order to make framework, element 22a, 22b or the following element 22a that is introduced at least have groove 23a, the 23b (see figure 3) of laying fin 12a and 12b.
[43] lower frame member 22a is bearing on the diapire 12c of pipeline 12, and the wall that diapire 12c passes when entering with electric heater unit is relative.By making element 22a have a type bar that matches with complementary projection on the diapire 12c, can improve leak tightness herein.
[44] upper frame member 22b can have the electronic control circuit 28 of electric heater unit 16.
[45] certain, can consider that also electronic heating apparatus 16 is installed in other possibility in the housing 10, it provides the excellent sealing along duct wall.Therefore, the framework of electric heater unit can be furnished with the type bar of projection, is inserted in the hollow projection on the duct wall.
[46] in another modification shown in Figure 4, the hollow recess 18a, the 18b that form on fin 18 ends of protruding 12a, the 12b of pipeline 12 inwalls and electric heater unit 16 cooperate.Fin 18 is passed by the heating pole 19 that has resistance element.
[47] Fig. 4,5 partly illustrates another embodiment that is used for the air heating apparatus of automobile seating accommodation according to of the present invention.
[48] heating arrangement comprises a housing 30, and housing 30 limits the pipeline 32 of an air to be heated.An air-liquid-type H Exch 34 and an electric heater unit 36 are installed in series in pipeline 32.Electric heater unit 36 is installed in the downstream of H Exch 34 along the direction (arrow F2) of air flows, at one between the conveyer (not shown) of H Exch 34 upstreams and outlet at the seating accommodation in electric heater unit 36 downstreams.
[49] common, the refrigerant fluid of automotive engine is provided for H Exch 34.H Exch for example is arranged in housing 30 in the mode of drawer, and occupies the whole square-section of pipeline 32 in the installation place.
[50] electric heater unit 36 can use basic unmodified resistance of resistance or CTP resistance.
[51] in an example shown, electric heater unit 36 proximity thermal exchangers 34, but only occupying the part in its residing pipeline 32 cross section, the complementary portion 33 in pipeline 32 cross sections is occupied by a valve 38.
[52] valve 38 can move between an off position (shown in Fig. 4 solid line) and at least one open position (for example shown in the dotted line of Fig. 4), at off position, and this complementary portion in valve closed conduct 32 cross sections.
When [53] valve 38 was closed, flow air almost all was forced to pass electric heater unit in pipeline 32.Like this, the accommodation coefficient in electric heater unit when operation no better than 100%.
When [54] valve 38 was opened, the portion of air stream in the pipeline 32 passes split channel 33 to be passed through outside heating arrangement.Therefore, the venting pressure loss that produces owing to the existence of electric heater unit, be that being reduced to of charge air is minimum, less than 5%.
[55] as shown in Figure 5, electric heater unit 36 by one by two side 40a, 40b and two frame parts, be that the framework that underframe 42a and upper frame 42b constitute surrounds.
[56] framework of electric heater unit 36 can be connected with H Exch 34, form one can be in putting into housing 30 before stack-mounted sub-component in advance.
[57] frame part 42a, 42b prolong from a side of electric heater unit 36, form side plate 44a, the 44b of the S. A. 38a that supports valve 38.Can stagger with the position of the mid-plane of electric heater unit in the position of S. A., so that provide required swing degree of freedom (Fig. 4) for valve 38.

[59] in addition, the electronic control circuit 48 of actuator 46 and electric heater unit 36 can be combined in the framework, for example in the frame element 42b of its prolongation 44b supporting actuator.
[60] when H Exch can not provide the required heat of flow air in the water back 12, the operation of control electric heater unit 36 when closing valve 38 was so that there is the best efficiency of heating surface.
[61] when the supplementary heating that no longer needs electric heater unit 36 to provide, the outage of electric heater unit, and valve 38 is opened.At this moment electric heater unit does not move, but split channel 33 open the minimization of loss that will make venting pressure.
[62] it is pointed out that valve 38 can move, and also can be provided with the either large or small open position of a plurality of split channels 33, so that regulate the charge air of this passage between its off position and a unique open position.
[63] therefore, can be according to the needs that begin that add hot air, in electric heater unit 36 operations, portion of air stream can be diverted in the passage 33 that partially opens.
[64] Fig. 6 and 7 illustrates a variant embodiment of electric heater unit and corresponding valve 38.
[65] Fig. 4,6 with Fig. 5,7 in common element with identical numeral, and no longer redescribe.
[66] according to this modification, the integral body that electric heater unit 36 and valve 38 constitute is independent of H Exch 34 and is installed in the housing 30.
[67] install and to implement with similar mode shown in Fig. 1-3.
[68] therefore, the assembly that electric heater unit 36 and valve 38 constitutes fits on two opposite edges of type bar 50a, 50b, and the protruding 32a, the 32b that form on type bar 50a, 50b and passage 32 inwalls cooperate.
[69] the type bar can have the outside U-shaped cross section of opening, and the shape of projection can be the fin that extend in the type bar.
[70] if with reference to Fig. 7, a 50a in the type bar links to each other with the side 40a of heating arrangement framework, and another type bar 50b extends between the end of side plate 44a, 44b.
[71] edge 40b, type bar 50b and side plate 44a, 44b encirclement can be by valve 38 osed top split channels 33.
[72] in this embodiment, enough leave at valve 38 under the condition of H Exch 36, the axle of valve 38 can be positioned at the mid-plane of electric heater unit 36.
