Abstract
The invention discloses a wall-mounted-type indoor unit of an air conditioner, wherein air can be introduced into a heat exchanger from different angles. The wall-mounted type indoor unit of the air conditioner comprises a shell, the heat exchanger and a wind wheel, wherein an air outlet and an air inlet are arranged on the shell, an air duct is formed between the air outlet and the air inlet, the heat exchanger and the wind wheel are arranged in the air duct, and the heat exchanger is of an arc body structure. The wall-mounted indoor unit of the air conditioner, with such a structure, not only has high heat-exchange efficiency and low noise, but also is beneficial to smooth flowing-down of condensed water at the same time.
Description
Technical field
The present invention relates to a kind of indoor apparatus of air conditioner, especially wall hanging type air conditioner indoor unit.
Background technology
Wall hanging type air conditioner indoor unit generally is made up of housing, heat exchanger and cross flow fan (comprising tubular wine wheel, spiral case, snail tongue).On housing, be provided with air outlet and air inlet, form the air channel between air outlet and the air inlet, heat exchanger and wind wheel are located in the air channel.Heat exchanger is the important component part of air conditioner room unit, and different heat exchange device structure has very big-difference to the indoor apparatus of air conditioner Effect on Performance.At present, people mainly concentrate on the heat exchange property of heat exchanger the research of wall hanging type air conditioner indoor unit, promptly consider how it is optimized from the heat exchange aspect.The raising that Along with people's requires heat pump performance, noise is low, air quantity greatly also progressively becomes the key factor that air-conditioning relates to.Therefore, be necessary from reducing noise and improving the air quantity aspect and how to consider that heat exchanging device structure and air conditioner structure are optimized.
As important component part of air conditioner room unit, the structure of heat exchanger has very important influence to indoor set interior flow field and sound field.Air-flow receives certain obstruction and constraint when flowing through heat exchanger, produce inevitable pressure drop, and the air-flow that gets into blower fan also demonstrates suitable inhomogeneities.From the angle of heat exchange, we hope mobile the be turbulent condition of air-flow in evaporimeter, to strengthen the heat exchange effect.Therefore, each designing unit and producer have developed many novel fin tube type surface coolers in recent years, like bellows-type, calking formula etc.; In these designs, the effect of special construction is to destroy flow boundary layer as far as possible, upsets and flows, and this has certain turbulence intensity with regard to the inlet air flow that makes crossflow fan.But from the angle analysis in crossflow fan flow field, then require inlet flow field more even, because the quality of inlet flow field directly has influence on the interior flow field (size and the position that comprise eccentric eddy) of crossflow fan and the uniformity of exit flow field.How under the prerequisite that guarantees heat exchange effect, improve inlet flow field, reduce noise? Seeking the reasonable Arrangement mode of heat exchanger and the Rational structure of indoor set promptly is a kind of effective solution.
Fig. 1 is the stereogram of traditional wall hanging type air conditioner indoor unit; Fig. 2 is the sectional structure chart of traditional wall hanging type air conditioner indoor unit.Like Fig. 1, shown in 2, heat exchanger 200 is arranged in the housing 100 with wind wheel 300, and air inlet 400 is above housing 100, and when operation of air conditioner, air is inhaled into from air inlet 400, gets into wind wheel through heat exchanger 200, discharges from the air outlet 500 of housing below again.The drawback of this structure is that the heat exchanger trailing edge is bigger apart from the variable in distance of wind wheel, can be found out by Fig. 1, and is minimum in A place distance, here air-flow the most rapidly, and the distance maximum at B place, the speed of air-flow is less relatively.This just causes air-flow bigger through the laggard strength difference of going into wind wheel of heat exchanger heat exchange, and the size and Orientation of air-flow is also inhomogeneous.In addition, in air-conditioning air inlet zone, exist a main inflow region, air-flow is comparatively concentrated in this zone.If adopt traditional heat exchanger arrangement, not only the inlet velocity size and Orientation of air-flow is extremely inhomogeneous, and dense degree also has very big difference.Simultaneously, multi-bended heat exchanger has opening at bending part, to when refrigeration condensed water mobile certain influence is arranged, and the fin opening part causes reviewing easily when manufacturing, and reviewing is easy to generate turbulent flow.Therefore, how considered optimizes inlet flow field when arranging heat exchanger, makes the inlet velocity field even.Generally speaking, if inlet flow field is optimized, the whole flow field of wind wheel also will be optimized so, and sound field also will make moderate progress, and the air inlet interaction noise that causes owing to inlet flow field is inhomogeneous also will reduce.
In addition, the air outlet of traditional wall hanging type air conditioner indoor unit is provided with snail tongue and wind guiding louver, and in the operation of air conditioner process, snail tongue and wind guiding louver place are prone to produce spiral, increase aerodynamic noise; Simultaneously, this structure makes that also air-out area is less and direction is single.
Summary of the invention
The technical problem that the present invention will solve provides a kind of heat exchanger and equates to the distance of wind wheel import, and promptly the wind wheel importer is to for radially, and this moment, air-flow was not turned back at inlet flow field, and air inlet is the most even, and flow losses are the wall hanging type air conditioner indoor unit of minimum also.
For addressing the above problem; Basic design of the present invention is: a kind of wall hanging type air conditioner indoor unit; Comprise housing, heat exchanger and wind wheel, on housing, be provided with air outlet and air inlet, form the air channel between air outlet and the air inlet; Heat exchanger and wind wheel are located in the air channel, it is characterized in that: said heat exchanger is the circular arc body structure.
