Description
Technical field
The utility model relates to a kind of field of automobile air conditioner, particularly the rearmounted evaporator of a kind of air conditioning for automobiles.
Background technology
Evaporator is one of major part of air conditioning for automobiles, the effect of evaporator is vaporization of being seethed with excitement in evaporator by the liquid refrigerant after reducing pressure by regulating flow, absorb the heat of evaporator surface surrounding air and lower the temperature, cold air blows in compartment by blower fan again, reaches the object of cooling.At present, evaporator comprises the housing with air outlet, the evaporator core being arranged on the blower fan in housing and being connected with expansion valve, described evaporator core is arranged between blower fan and air outlet, by blower fan, hot outside is sucked, blow to the cooling of evaporator core place, through cooled wind again from air outlet blowout, reach the object of cooling-air.Existing evaporator is mostly mounted in the top of automobile, compares and takies interior space, and meanwhile, during starting of air conditioner, the noise of blower fan is comparatively large, affects the traveling comfort taken.In order to solve the problem, first some vehicle changes evaporator into rearmounted or prefixed form.As China national Department of Intellectual Property announced on October 23rd, 2013, notification number is the automobile finisher of 203246287, the housing of this evaporator is placed between right back backplate in compartment and right lateral side vehicle body, and air outlet is connected with the cold air import being located at ceiling in car by airduct.The problem that existing evaporator takes up room greatly although this evaporator to some extent solves, noise is large in use procedure, but also have the following disadvantages: the air channel that blower fan blowout wind is formed is L-shaped, there is dead angle in the contact surface territory of wind and evaporator core, thus affects air output and the refrigeration of evaporator.
Summary of the invention
The purpose of this utility model is that existing rearmounted evaporator air output is low, the problem of poor refrigerating efficiency in order to solve, and the rearmounted evaporator of a kind of air conditioning for automobiles provided.
To achieve these goals, the rearmounted evaporator of air conditioning for automobiles designed by the utility model, it comprise there is mounting seat and air outlet housing, be arranged on blower fan in housing and evaporator core, described evaporator core is arranged between blower fan and air outlet, and the wind direction flow-guiding channel that described blower fan and air outlet are formed is in the shape of the letter V; Described evaporator core is vertically arranged in the middle part of wind direction flow-guiding channel, the lower end of blower fan, and the two ends of evaporator core are all fixed in inner walls, and the mounting seat under evaporator core and housing is perpendicular.During work, refrigerant is by flowing into evaporator core after expansion valve throttling, and the refrigerant after throttling evaporates and absorbs heat in evaporator core, evaporator core ambient air temperature is reduced and becomes cold air, starts blower fan and is blown out from air outlet by cold air.
Further, described expansion valve is H type expansion valve, is arranged on the outer wall of housing, is connected by connection pipe with evaporator core.The small volume of H type expansion valve, refrigerant by expansion valve and connection pipe and evaporator core UNICOM, thus transmits cold air.
Further, be provided with an air quantity diversion block between housing sidewall, between blower fan and evaporator core, described air quantity diversion block is one piece of downward arc.Fast by arranging this air quantity diversion, the wind at blower fan place can be divided into upper and lower two parts guiding evaporator core place, the wind that blower fan is blown is not staying dead angle through evaporator core, more balances, is evenly distributed in around evaporator core.
Compared with prior art, the rearmounted evaporator tool of air conditioning for automobiles that the utility model obtains has the following advantages:
1, by evaporator core is vertically arranged, such structure makes gas longitudinally to circulate, and cold air can scatter uniformly in core body, has constantly taken away the cold air in whole core body during air intake, core body just not easily frosting, final refrigeration also can obviously promote.
2, wind direction flow-guiding channel is in the shape of the letter V design, and the wind energy that blower fan is produced all is passed to evaporator core place enough to greatest extent, thus hot blast is become cold wind, is transported to air outlet place, can improve air output and the refrigerating capacity of evaporator by actv..
3, the upper and lower side of evaporator core is all in wind direction flow-guiding channel, and the wind sufficient heat exchange with in wind direction flow-guiding channel, further ensure that its cooling rate and refrigerating capacity.
Accompanying drawing explanation
Fig. 1 is the structural representation of evaporator in embodiment.
In figure: housing 1, mounting seat 11, air outlet 12, wind direction flow-guiding channel 13, blower fan 2, evaporator core 3, expansion valve 4, connection pipe 5, air quantity diversion block 6.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
The rearmounted evaporator of the air conditioning for automobiles that the present embodiment provides, as shown in Figure 1, it comprise there is mounting seat 11 and air outlet 12 housing 1, be arranged on blower fan 2 in housing 1 and evaporator core 3, described evaporator core 3 is arranged between blower fan 2 and air outlet 12, and is connected with expansion valve 4.During installation, housing 1 is arranged on the left back wheel hub of automobile or right back wheel hub, and housing 1 is fixedly connected with wheel hub by mounting seat 11.
The wind direction flow-guiding channel 13 that above-mentioned blower fan 2 and air outlet 12 are formed is in the shape of the letter V; Evaporator core 3 is vertically arranged in the middle part of wind direction flow-guiding channel 13, the lower end of blower fan 2, and the two ends of evaporator core 3 are all fixed on housing 1 inwall, and evaporator core 3 is perpendicular with the mounting seat 11 under housing 1.
