Abstract
The invention discloses a double-parallel-flow evaporator assembly, and relates to the technical field of automobile air conditioner manufacturing. The double-parallel-flow evaporator assembly comprises an evaporator core body and an expansion valve. The evaporator core body is of a double-parallel-flow structure, and the expansion valve is in an H shape. The evaporator core body is communicated with the expansion valve through a connecting pipe. The evaporator core body is arranged in an evaporator core body box in an evaporator shell, the connecting pipe and the expansion valve are arranged on the outer portion of the evaporator core body box, and the evaporator core body and one end of the connecting pipe are fixedly connected together through a fixing box in a radial sealing mode. The other end of the connecting pipe is inserted into the expansion valve, and the connecting pipe and the expansion valve are fixedly connected together through a fixing bolt and a press plate. According to the double-parallel-flow evaporator assembly, the problems that an air conditioning evaporator for a construction engine is large in mounting size, poor in heat dissipation performance, poor in vibration resisting performance of the expansion valve and prone to loosening, the sealing performance of a whole air conditioner system is influenced, and maintenance is inconvenient are solved.
Description
Technical field
The present invention relates to construction engine air-conditioning technical field, especially a kind of efficiently two parallel flow evaporator core assembly apparatus.
Background technology
Construction engine multiplex (MUX) does field in the open, and working environment is exceedingly odious; For betterment works locomotive driving operating personnel's working environment, the general supporting air-conditioning system that has of construction engine, for regulating the temperature of driving in building.Be contained in the refrigerating function of driving the evaporator assembly in building by evaporator core assembly reality; And expansion core is made up of evaporator core assembly, expansion valve component two parts.The evaporator core of existing construction engine air-conditioning also adopts more traditional pipe type and stacked structure, and this structure heat dispersion is very limited; But can only merely rely on the volume that increases evaporator core to realize if improve heat dispersion, installation volume increases, and can reduce refrigeration along with the corresponding windage of increase of volume increases; And the general F type expansion valves that use of the expansion valve that this structure adopts, its seal form is end face seal, when use, is connected with system by screwed pipe joint, on construction engine, vibration resistance is poor, easily causes looseningly, affects the sealing of whole air-conditioning system; more Traditional evaporator assemblies mounting structure is that evaporator core assembly is all wrapped in to enclosure interior on the other hand, and changing expansion valve need, by housing completely knocked down, waste time and energy.On the other hand, strengthen driving space, building owing to meeting the demand needs of the increasing of user to loader drive operating space, space, driving building after adjustment, the space of leaving evaporimeter installation for is relatively little, and space becomes, and to evaporimeter refrigeration performance, requirement further improves greatly; On the basis of the existing air-conditioning installing space of car load, apply traditional evaporator core to promote the difficulty of heat pump performance very large ensureing that air-conditioning system parts do not exceed in this case, and cost also can increase.
Summary of the invention
The object of this invention is to provide a kind of two parallel-flow evaporator assembly, this pair of parallel-flow evaporator assembly it can to solve engineering machine vehicle air-conditioner evaporator installation volume large, heat dispersion is poor and expansion valve vibration resistance is poor, easily loosening, affects the problem of whole air-conditioning system sealing.
In order to address the above problem, the technical solution used in the present invention is:
This pair of parallel-flow evaporator assembly, includes evaporator core and expansion valve, and described evaporator core is the evaporator core with two concurrent flow structures, and described expansion valve is H type expansion valve; Described evaporator core is connected with expansion valve by tube connector; Described evaporator shell is arranged in the evaporator core case in evaporator shell, and described tube connector and described expansion valve are arranged on the outside of described evaporator core case.
In above technical scheme, further scheme is: one end of described evaporator core and described tube connector is fixed together by set bolt radial seal; The other end of described tube connector inserts in described expansion valve, by set bolt and pressing plate, described tube connector and described expansion valve is fixed together.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention adopts the evaporator core of two concurrent flow structures that radiating efficiency is high, under equal volume, has higher heat dispersion, and the performance of air-conditioning is improved.
2, the present invention adopts the H type expansion valve of accurate positioning; And expansion valve is arranged on to evaporator core case outside, easy access and replacing, expansion valve only needs bolt to fix, and when dismounting, needed space is little, easily maintenance.
3, H expansion valve of the present invention adopts the form of radial seal, and sealing and vibration resistance are all good.
