Description
Technical field
The present invention relates to a kind of multi-fan refrigerator air duct.
Background technology
Along with development and the continuous lifting of level of consumption of technology, volume frostless, big, the rapid wind cooling refrigerator that freezes are increasingly becoming
The close product looked at of consumption institute.Wind cooling refrigerator relatively direct cooling refrigerator is compared, and has many advantages.But relative, the consumption of wind cooling refrigerator
Electricity is also above general direct cooling refrigerator.Therefore, how to reduce wind cooling refrigerator power consumption, designing energy-efficient air channel structure becomes
The emphasis of each producer research and probe.
Existing wind cooling refrigerator air channel is mainly by for the evaporator assemblies of heat exchange, duct main, fan component, supply air duct with return
Wind air channel forms.As a example by hiding lower frostbite cold refrigerator in dual temperature district, refrigeration is main with air channel circulation uses following 2 kinds of modes.
(1) one is single evaporator, single fan structure.Duct main and vaporizer are installed in refrigerating chamber, blow at cold room
MOD is installed on air channel, and temperature sensor is all arranged in room between 2.By door opening and closedown, control cold preservation
The refrigeration of room.The defect of this kind of scheme is, owing to vaporizer and circulating fan are placed on refrigerating chamber, refrigerating chamber refrigeration cannot be single
Solely close.Thus when freezing reaches design temperature, and when cold room needs to continue refrigeration, freezing temperature may proceed to decline, and makes
Become the energy waste that refrigerating chamber is supercool and unnecessary.
Meanwhile, because of refrigerating return air temperature, refrigeration chamber creates large effect to evaporating temperature, directly results in freezing
Return air heat transfer temperature difference is relatively low, and when refrigeration, freezing indoor temperature goes up not down often.
Due to above-mentioned actual condition, this kind of endless form can cause evaporating temperature and system effectiveness to be freezed at refrigerating simultaneously
Notable change is there is so that system, in each cooling cycle, has longer time deviation optimum operating condition during with freezing separate refrigeration
Point, causes system effectiveness relatively low, and power consumption is bigger than normal.
(2) another kind is double evaporators dual-system structure.Between the circulation of air channel, room and kind of refrigeration cycle all independent, each room have from
The vaporizer of body, fan stack assembly etc..This kind of scheme avoids the shortcoming of the cooling condition deviation that former scheme is caused,
Between the control such as the design by valve and refrigeration system is each, the flow of room, can realize each compartment temperature and independently control.The shortcoming of the program
Being, owing to each room is required for independent evaporator assemblies, shared space is relatively big, causes wind cooling refrigerator plot ratio relatively
Low, add substantial amounts of material and manufacturing cost.
As shown in Figure 5, for one of prior art dual temperature district refrigerator air flue structure, single aerofoil fan 5 and air door 8 is used to tie
Structure realizes many warm areas function, duct main and vaporizer and is installed in refrigerating chamber, is provided with electronic wind on cold room supply air duct
Door, and between 2, temperature sensor is all arranged in room, by door opening and closedown, controls the refrigeration of cold room.This kind of scheme
Defect be, owing to vaporizer and circulating fan are placed on refrigerating chamber, refrigerating chamber refrigeration cannot individually be closed, thus when freezing
Reach design temperature, and when cold room needs to continue refrigeration, freezing temperature may proceed to decline, cause refrigerating chamber supercool and need not
The energy waste wanted.Meanwhile, when door opening and closedown, air circulation changes, and because refrigerating return air wind path is
Relatively independent, so when door opening and closedown, evaporating temperature and system effectiveness can significantly change so that system is in each system
In cold cycle, having longer time deviation optimum operating condition point, cause system effectiveness relatively low, power consumption is bigger than normal.
For many warm areas wind cooling refrigerator refrigerator, air channel is the most also only with single fan and the combining form of air door, owing to air channel is longer,
Farther out, produced by single fan, blast and air quantity are the most not enough for air supplying distance, cause refrigerating efficiency low, and power consumption is big.Along with wind
Becoming increasingly popular of cold refrigerator, above-mentioned technological difficulties become problem demanding prompt solution.
Summary of the invention
The present invention is for avoiding weak point present in above-mentioned prior art, it is provided that a kind of multi-fan refrigerator air duct, existing to solve
Having in technology, between low during height when ducting assembly takies larger volume, refrigerating efficiency, part, room cannot the asking of separate refrigeration and closedown
Topic.
The present invention solves that technical problem is by the following technical solutions.
A kind of multi-fan refrigerator air duct, it is structurally characterized in that, including can and air cooling refrigerator evaporator, refrigerator each between room air-supply wind
Road and return airway form the duct main of complete ducting system, and described duct main includes front shroud, back shroud, foam wind
Road and at least two fan；Described foam air channel is arranged between described front shroud and described back shroud；
It is provided with fixed plate on described back shroud, by described fixed plate, the vaporizer of described back shroud with refrigerator is fit together.
The construction features of a kind of multi-fan refrigerator air duct of the present invention lies also in:
Described fixed plate is aluminum plate.
Described fan is aerofoil fan and/or centrifugal fan.
Described centrifugal fan is closed type centrifugal fan or open centrifugal fan.
Compared with the prior art, the present invention has the beneficial effect that:
A kind of multi-fan refrigerator air duct of the present invention, mainly includes front shroud, back shroud and foam air channel etc..This refrigerator air duct is extremely
Being provided with 2 fans less, each fan has independent air channel, can at least between 2 room or region blow.This kind of wind
Road structure can carry out different designs for the many temperature-zone refrigerators of single evaporator and multi-evaporator；By reasonably design, can realize each
Individual warm area reaches design temperature the most simultaneously, it is ensured that system Effec-tive Function in whole cooling cycle, reduces the consumption of refrigerator
Electricity.This air channel structure can solve in prior art, low during height, part when ducting assembly takies larger volume, refrigerating efficiency
Between room cannot separate refrigeration and the problem of closedown.
The refrigerator air duct of the present invention, in particular for multi-chamber's wind cooling refrigerator, can be come individually by the design in multiple fans and air channel
Ground or simultaneously cool down multiple rooms.
A kind of multi-fan refrigerator air duct of the present invention, has cocoa and carries out difference for the many temperature-zone refrigerators of single evaporator and multi-evaporator
