Abstract

The utility model provides a novel HVAC (heating ventilating and air conditioning) assembly of an automobile air conditioner. An internal regulator consisting of a blower motor assembly and a warm air core body is fixed on the HVAC assembly through an injection molding shell; an external air duct comprises a left foot blowing air duct, a right foot blowing air duct, a left face blowing air duct, a right face blowing air duct, an inner-outer circulating air door and a cold-warm air door; an independent defrosting air opening and a middle face blowing air opening are arranged on the HVAC assembly and are fixed on the HVAC assembly through clamping spring nuts; and the left foot blowing air duct, the right foot blowing air duct, the left face blowing air duct and the right face blowing air duct are respectively independent blow molding pieces which are riveted with one another and supported by brackets. Therefore, the interchangeability of the HVAC assembly is greatly improved.

Description

A kind of novel automobile air-conditioner HVAC assembly

Technical field

The utility model relates to a kind of automotive hvac air-conditioning.

Background technology

The air outlet that the air conditioning for automobiles HVAC assembly function of prior art will defrost, blow pin, blow face is integrated on the left and right sides housing of HVAC assembly, and the HVAC assembly volume of this structure is bigger.Common different bridge instrumentation platform inner structure difference, and limited by the inner space, it is very big that the excessive air channel of air conditioner ventilation layout is influenced by the instrument desk inner structure, the design that dock with the HVAC passage in the ventilation air channel is difficult, so the bulky air conditioning for automobiles HVAC of assembly is difficult to general under the different instrument platform.Also there be not at present the exchange of HVAC assembly on different operator'ies compartment in integrated air port.Simultaneously the type air conditioning HVAC assembly adopts pipe type evaporator and pipe type warm braw, and volume is big, and the dispersed placement difficulty generally adopts arranged superposed, and this structure ventilation resistance is big, cause operating noise big, blower motor power consumption height.When arranged superposed was closed inefficacy at warm braw hot water, refrigerating function can be lost, poor reliability.

Summary of the invention

In order to realize that air conditioning for automobiles HVAC assembly can realize that the exchange of different operator'ies compartment is general, reduce operating noise simultaneously, reduce power consumption, improve system reliability, the utility model proposes a kind of novel automobile air-conditioner HVAC assembly.

The technical solution of the utility model is: a kind of novel automobile air-conditioner HVAC assembly, and by the blower motor assembly, the warm braw core body constitutes internal regulator, is fixed on the HVAC assembly by injection-moulded housing; The left and right pin air channel of blowing, left and right face air channel, internal-external cycle throttle, the changes in temperature air door etc. of blowing formed external air channel, it is characterized in that: the HVAC assembly is provided with independent defrosting air port and centre and blows the face air port and be fixed on the HVAC assembly by the jump ring nut; The left and right pin air channel of blowing, the left and right face air channel of blowing is respectively independent blowing part and rivets mutually, passes through stent support.

The utility model has been considered when designing under the requirement of the refrigeration that guarantees operator's compartment of the same type, heating energy, adopt advanced at present heat exchanger and relevant pioneering technology, reduce HVAC not with the volume of air port assembly part as far as possible, and each air outlet is designed to separate piece, the less HVAC of volume is not with the air port assembly part interchangeable general at different operator'ies compartment like this.And each air outlet redesigns the exchange commonality that can finish at different operator'ies compartment according to different bridge instrumentation platform structures.Newly-increased number of molds is few when the HVAC assembly of the new operator's compartment of exploitation like this, and other part is general fully except 6 air ports and 2 fixed supports.Greatly reduce development and maintenance cost.

On inner structure is arranged, optimize air inlet structure, make that the vaporizer side air intake is even.Reduce the probability that evaporator freezes effectively, improved the degree of utilization of evaporator.Adopt evaporator and warm braw arranged apart, improved reliability, reduction windage, the reduction operating noise of refrigeration.Optimize inner distinguished and admirable to, reduce to reduce windage.

The specific embodiment

A kind of novel automobile air-conditioner HVAC of the utility model assembly, its structure is seen accompanying drawing 1 and accompanying drawing 2, mainly is not with air port assembly part 1, defrosting air port 2, the right side to blow pin air port 3, the right side by HVAC and blows face air port 4, a left side and blow that face air port 6 is blown in face air port 5, centre, a left side is blown pin air port 7 and formed.Air conditioning functions such as the refrigeration of this later-model air conditioning for automobiles HVAC assembly, heating, pattern adjusting, blower motor adjusting are not with the air port assembly part to finish by HVAC, and this part is compact as far as possible, so that the layout of air-out interface.Dock in the corresponding air channel with car load of each air-out interface on need the HVAC assembly when HVAC assembly is installed on car load.These later-model six air-out interfaces are individual components on the HVAC assembly, the attachment point of six air-out interfaces and be fixed on HVAC and be not with assembly part design in air port to finish, like this when general other vehicle instrument desks, only need to design six new air-out interfaces and dock with the car load air channel and get final product.Only need to increase the mould of six air-out interfaces of new design, utilize the most existing product just can produce the air conditioning for automobiles HVAC assembly that cooperates other new model, can reduce cost of development greatly like this.

Optimization of inside structure is seen accompanying drawing 3, mainly is made up of internal-external cycle throttle 1, internal-external cycle throttle 29, evaporator core 10, cold and hot air door 11, warm braw core body 12.The internal-external cycle throttle of this later-model air conditioning for automobiles HVAC assembly adopts arc plate structure, under the situation of compact conformation, makes wind under interior circulation, outer circulation, two states reach the whole windward side of evaporator surface easily as far as possible.This later-model air conditioning for automobiles HVAC assembly evaporator core and warm braw core body are arranged apart.The cooling and warming wind direction is regulated and is finished by cold and hot air door 11, natural wind passes through internal-external cycle throttle, air-conditioning work during refrigerating state, the inner refrigerant circulation of evaporator, natural wind is by the evaporator core drop in temperature, cold and hot air door slides, and organizes air to flow through the warm braw core body, and pass through blowing engine, air port, air channel behind the drop in temperature flow in the operator's compartment.Natural wind passes through internal-external cycle throttle, heat the state space-time accent and do not work, cold and hot air door slides, and air flows through hot engine water heating warm braw core body, natural wind heats up by warm braw core body temperature, and pass through blowing engine, air port, air channel behind the temperature build-up flow in the operator's compartment.Thick high-efficiency evaporator and the parallel flow warm braw of this present state-of-the-art 38mm of novel employing simultaneously, the degree of utilization height of evaporator like this, good cooling effect, ventilation resistance is little, and operating noise is little, the reliability height.
