Abstract
The invention provides a kind of heat exchanger for air-conditioner indoor machine fin flow guiding structure, obstruct reinforcement is set between upper cover panel beating and evaporimeter top fin, between upper cover panel beating and obstruct reinforcement, sealing gasket is set; By analyzing the ventilation situation of indoor set heat exchanger fin, find the position of heat exchanger fin generation fin sound, improved by structure and stop passing through of wind, thus eliminate fin sound, be easy to operation, simple, and low processing cost, add the mechanical strength of complete machine framework, result of use is good simultaneously, cost-saving, easy for installation.
Description
Technical field
The present invention relates to a kind of indoor apparatus of air conditioner air channel structure, specifically refer to the fin flow guiding structure at heat exchanger for air-conditioner indoor machine air outlet place.
Background technology
The buried indoor set in air-conditioning sky is the new architecture of answering the change of the multifarious demand in market and overall fitting space and growing up, and is applicable to the occasion of installing and maintenance width is less, is particularly useful for small apartment family and uses.Present user is more and more higher for the requirement reducing air conditioner noises, because the buried indoor set in family expenses sky can be arranged on bedroom, so more need the noise level effectively controlling indoor apparatus of air conditioner, and do not allow to occur abnormal noise, thus realize comprehensively quiet effect.But due to indoor apparatus of air conditioner structure itself, the buried indoor set in most of sky exists the noise that high frequency blows fin to be difficult to eliminate, and often can cause customer complaint.
The method that prior art solves this type of fin souffle problem increases refluence plate in air outlet side, the wind that fan is blown out is more smooth-going, thus make to blow to wind energy on fin perpendicular through, thus eliminate fin sound, but baffle configurations is complicated, enter repeatedly Theoretical Design and test and just can find reasonable scheme, and buried indoor set inner space, home-use sky is compact, use the words inherent space constraints of deflector, be difficult to install, and the increase of complete machine cost is also more.
Summary of the invention
For prior art Problems existing with not enough, technical problem to be solved by this invention is, by analyzing the ventilation situation of indoor set heat exchanger fin, find the position of heat exchanger fin generation fin sound, improved by structure and stop passing through of wind, thus eliminate fin sound, simultaneously cost-saving, easy for installation.
For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of heat exchanger for air-conditioner indoor machine fin flow guiding structure is provided, obstruct reinforcement is set between upper cover panel beating and evaporimeter top fin, between upper cover panel beating and obstruct reinforcement, sealing gasket is set.
Above-mentioned heat exchanger for air-conditioner indoor machine fin flow guiding structure, it intercepts reinforcement and is entrenched in the angle formed between fin windward side, evaporimeter top and upper cover panel beating.
Above-mentioned heat exchanger for air-conditioner indoor machine fin flow guiding structure, it intercepts reinforcement height is 8-12mm.
Above-mentioned heat exchanger for air-conditioner indoor machine fin flow guiding structure, it intercepts reinforcement longitudinal section is " U " shape structure.
Above-mentioned heat exchanger for air-conditioner indoor machine fin flow guiding structure, its sealing gasket extends to lee face by fin windward side, evaporimeter top.
Heat exchanger for air-conditioner indoor machine fin flow guiding structure tool of the present invention has the following advantages and Advantageous Effects:
Heat exchanger for air-conditioner indoor machine fin flow guiding structure of the present invention, reinforcement fitted seal pad is simultaneously intercepted by arranging between upper cover panel beating and evaporimeter top fin, effectively can intercept the air-flow by evaporimeter top fin, thus fundamentally solve high frequency and blow the noise produced problem of fin.
Intercepting reinforcement is entrenched in the angle formed between fin windward side, evaporimeter top and upper cover panel beating, draught effect is intercepted on the one hand better on windward side, on the other hand, it is more smooth that this chimeric structure can make inner air channel structure circulate, and avoids other noises occurring that air motion produces.
Intercepting reinforcement height is 8-12mm, not only makes whole framework intensity strengthen because increasing reinforcement, and effectively ensures that intercepting high velocity air blows to this position of fin, evaporimeter top generation noise.
Intercepting reinforcement longitudinal section is " U " shape structure, and weight reduction on the one hand, is convenient to processing simultaneously; On the other hand, it is more smooth that this fairshaped surface design makes inner air channel structure circulate, and avoids other noises occurring that air motion produces.
Sealing gasket extends to lee face by fin windward side, evaporimeter top, seals the gap between upper cover panel beating and evaporimeter top fin more comprehensively, intercepts air-flow, prevent noise.
The scheme of heat exchanger for air-conditioner indoor machine fin flow guiding structure of the present invention is easy to operation, simple, and low processing cost, and add the mechanical strength of complete machine framework, result of use is good simultaneously.

Detailed description of the invention
As shown in Figure 2, heat exchanger for air-conditioner indoor machine fin flow guiding structure of the present invention, arrange between upper cover panel beating 1 and evaporimeter top fin 8 and intercept reinforcement 9, between upper cover panel beating 1 and obstruct reinforcement 9, sealing gasket 7 is set, intercepting reinforcement 9 is entrenched in the angle formed between fin 8 windward side, evaporimeter top and upper cover panel beating 1, and intercepting reinforcement 9 is highly 8-12mm, is preferably 10mm, longitudinal section is " U " shape structure, and sealing gasket 7 extends to lee face by fin 8 windward side, evaporimeter top.
The course of work of the present invention is as follows:
The high velocity air of the blowout of centrifugal blower 5, air outlet 4 is blowed to by air inlet 3, arrange between upper cover panel beating 1 and evaporimeter top fin 8 and intercept reinforcement 9, between upper cover panel beating 1 and obstruct reinforcement 9, sealing gasket 7 is set, effective obstruct by the air-flow of evaporimeter top fin 8, thus is fundamentally solving high frequency and is blowing the noise produced problem of fin; Intercepting reinforcement 9 is entrenched in the angle formed between fin 8 windward side, evaporimeter top and upper cover panel beating 1, windward side intercepts draught effect better, it is more smooth that this chimeric structure can make inner air channel structure circulate, and avoids other noises occurring that air motion produces; Intercepting reinforcement 9 is highly 8-12mm, be preferably 10mm, not only make whole framework intensity enhancing, and this position of crack effectively avoiding high velocity air to blow between evaporimeter top fin 8 and upper cover panel beating 1 produces noise.Intercepting reinforcement 9 longitudinal section is " U " shape structure, and weight reduction, is convenient to processing.Sealing gasket 7 extends to lee face by fin 8 windward side, evaporimeter top, seals the gap between upper cover panel beating and evaporimeter top fin more comprehensively, intercepts air-flow, prevent noise.
Use embodiment of the present invention scheme, when obstruct reinforcement 9 is highly 10mm, the test data with structure in prior art contrasts as shown in Figure 3, and can be found by contrast, at 2000-3000HZ, average noise value obviously reduces 2-3dB.
The above is only to preferred embodiment of the present invention, and be not do other forms of restriction to the present invention, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But, everyly do not depart from the present invention program's content, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and remodeling, still belong to protection scope of the present invention.
