Background technique

Heating,Ventilating and Air Conditioning assembly is that air conditioning for automobiles realizes one of refrigeration or the most important components of heat-production functions, because it is mounted on Inside crew module, therefore to the more demanding of its level of noise.And one of the noise factor for influencing automobile Heating,Ventilating and Air Conditioning assembly is exactly it Inner flow passage structure (participates in Fig. 1), and the inner flow passage structure of Heating,Ventilating and Air Conditioning assembly includes fresh wind port left shell 1, the right shell of fresh wind port Body 2, air duct upper housing 3, internal-external cycle throttle 4, warm wind motor 5, right shell body 6, air duct lower case 7 and left shell 8.Existing HVAC is empty Adjusting the air duct upper housing 3 of assembly is 55mm with the center line C of runner at a distance from, the center line C of air duct lower case 7 and runner away from From for 98mm, and warm wind motor 5 arranges (referring to fig. 2) perpendicular to ground horizontal line, this Heating,Ventilating and Air Conditioning assembly inner flow passage knot Structure is rotated by warm wind motor, and the blade on warm wind motor 5 is made to drive air to generate the air-flow for blowing to Heating,Ventilating and Air Conditioning air outlet, The air-flow of generation strikes in the runner inner wall of Heating,Ventilating and Air Conditioning case, and appearance is because of air duct upper housing 3, air duct lower case 7 during this Uneven with runner distance between centers, generating air-flow cannot uniformly spread in transmission process, also generate vortex, turbulent flow, reduce Air quantity, and biggish noise is generated, reduce comfort level.

Therefore, it is necessary to develop a kind of inner flow passage structure of new Heating,Ventilating and Air Conditioning assembly.

Utility model content

This is to provide a kind of inner flow passage structure of Heating,Ventilating and Air Conditioning assembly with novel purpose, in warm wind motor driven air During generating the air-flow for blowing to Heating,Ventilating and Air Conditioning air outlet, air quantity can be effectively improved, air-flow is prevented to be hindered, and drop Noise is generated in the low Heating,Ventilating and Air Conditioning assembly course of work.

The inner flow passage structure of Heating,Ventilating and Air Conditioning assembly described in the utility model, including air duct upper housing, and and air duct The air duct lower case that upper housing is cooperatively connected, the air duct upper housing and air duct lower case surround to form runner；The warm wind electricity Machine is mounted in air duct upper housing and air duct lower case；

The upper end of the axial line of the warm wind motor is tilted to the right, and the folder between the axial line and vertical line of warm wind motor Angle is 3 °~7 °；

The right end of the center line of the runner tilts down, and the angle between the center line and horizontal line of runner be 3 °~ 7°。

Further, the angle between the axial line and vertical line of the warm wind motor is 5 °；

Angle between the center line and horizontal line of the runner is 5 °.

The utility model has the advantage that the axial line of the warm wind motor in Heating,Ventilating and Air Conditioning assembly and vertical line offset Positive 5 degree, and runner center line at warm wind motor and horizontal line are at positive 5 degree of adjustment；By arrange above and runner adjust energy Being effectively improved air-flow, uniformly diffusion and air quantity transmit and lead to generate vortex, turbulent flow in uneven situation in runner, improve simultaneously Air quantity, reduces the operating noise of Heating,Ventilating and Air Conditioning assembly air outlet.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

The inner flow passage structure of Heating,Ventilating and Air Conditioning assembly as shown in Figure 3 and Figure 4, including fresh wind port left shell 1, fresh wind port are right Shell 2, air duct upper housing 3, internal-external cycle throttle 4, warm wind motor 5, right shell body 6, air duct lower case 7 and left shell 8.Wherein, Fresh wind port left shell 1 and the encirclement of fresh wind port right shell body 2 form fresh wind port, and internal-external cycle throttle 4 is arranged in 1 He of fresh wind port left shell In the cavity that fresh wind port right shell body 2 is formed.The air duct upper housing 3 and the encirclement of air duct lower case 7 form runner, and are located at fresh air The lower section of mouth.The warm wind motor 5 is mounted in air duct upper housing 3 and air duct lower case 7.The right shell body 6 and left shell 8 are matched Close connection.The upper end of the axial line D of the warm wind motor 5 is tilted to the right, and between the axial line D and vertical line A of warm wind motor 5 Angle be 3 °~7 °.The right end of the center line C of the runner tilts down, and between the center line C and horizontal line B of runner Angle is 3 °~7 °.
