Abstract
The utility model relates to a fan type heat exchanger for air conditioners. The utility model comprises a motor 14, a group of blades 16 which are arranged in a cylinder shape with a definite distance to form a fan, a pair of blade fixed seats 8 and 12 for arrangement of the blades 16, a fan shaft 5 and a pair of close covers 7, wherein, each blade 16 is hollow; the blade fixed seats 8 and 12 also comprise a pair of refrigerant through grooves 10 and 17 and reflux chambers 9 with the number equal to the number of the blades 16; the refrigerant through grooves 10 and 17 are communicated with the reflux chambers 9 which are communicated with hollow cavities of the blades 16; the fan shaft 5 also comprises a pair of refrigerant lead out and refrigerant lead in holes 6 and 18 which are respectively communicated with the refrigerant through grooves 10 and 17; the close covers 7 are covered on the blade fixed seats 8 and 12, and are positioned at one sides of the reflux chambers 9. The utility model has the advantages of excellent heat exchange performance, and integral volume of an inner machine of the air conditioners reduction.
Description
The utility model discloses a kind of idle call fan type heat exchanger, is to the blower fan of existing air-conditioning and the improvement of heat exchanger.
In the indoor set of traditional air-conditioning, these two on blower fan and heat exchanger parts independently separately are set respectively, and heat exchanger remains static.The shortcoming of this structure is: at first, the heat exchange property of heat exchanger is low, because in the air-conditioning work process, it can't realize cold air/hot gas is stirred; Secondly, the volume of air-conditioning is bigger, because it will satisfy to reserve heat exchanger and the necessary space requirement of blower fan is set.
The purpose of this utility model be to provide a kind of with blower fan and heat exchanger in traditional indoor apparatus of air conditioner unite two into one, heat exchanger by static become motion, heat exchange property is good, idle call fan type heat exchanger that can littleization indoor apparatus of air conditioner volume.
The purpose of this utility model reaches like this, a kind of idle call fan type heat exchanger, it comprises motor 14, the space certain distance is cylindric arrangement and constitutes one group of fan blade 16 of fan, be used to be provided with a pair of fan blade holder 8 of one group of fan blade 16,12, fan shaft 5, a pair of capping 7, each fan blade 16 is a hollow, a pair of fan blade holder 8,12 also include a pair of cold-producing medium groove 10,17 and the back cavity 9 that equates with fan blade 16 quantity, cold-producing medium groove 10,17 communicate with back cavity 9, back cavity 9 communicates with the hollow cavity of fan blade 16, fan shaft 5 also includes a pair of cold-producing medium and draws, hand- hole 6,18, cold-producing medium is drawn, hand- hole 6,18 respectively with a pair of cold-producing medium groove 10,17 communicate, a pair of capping 7 cap seals are at a pair of fan blade holder 8, on 12, and be positioned at one of back cavity 9 side.
The utility model makes the effect of one group of fan blade 16 with heat exchanger owing to done above-mentioned improvement, therefore not only has the heat exchange property excellence, and has the advantage that can dwindle the overall volume of indoor apparatus of air conditioner greatly.
Below in conjunction with accompanying drawing the utility model is further described below.
Fig. 1 is the utility model structure chart.
Fig. 2 is installed on the enforcement illustration on the indoor set of wall-hanging air conditioner for the utility model.
The shape of fan blade 16 of the present utility model is a watt shape.Help improving or improving the effect that cold air/hot gas blows out from air door 23 like this.
The utility model is considered the factors such as intensity of fan blade 16, can be at the place, centre position of a pair of fan blade holder 8,12, the place, centre position that also is fan blade 16 sets up fan blade fixed disk 11, and on the disk body of fan blade fixed disk 11, offer in order to intert the fan blade jack 15 of fan blade 16, the quantity of fan blade jack 15 equates with the quantity of fan blade 16.The number of setting up fan blade holder 11 certainly between a pair of fan blade holder 8,12 can be according to needing increase and decrease.
Two ends of one group of fan blade 16 of the present utility model are plugged on a pair of fan blade holder 8,12, the hollow cavity of each fan blade 16 communicates with back cavity 9 on the fan blade holder 8,12, and back cavity 9 communicates with cold-producing medium groove 10,17, cold-producing medium groove 10,17 again respectively with fan shaft 5 on cold-producing medium draw, hand- hole 6,18 communicates, cold-producing medium is drawn, hand- hole 6,18 communicates with the seal nipple 2 that sets separately.
The version of seal nipple 2 described in the utility model can be according to needing selection, select the structure of form shown in Figure 1 in this way, front end at seal nipple 2 processes liquid inlet and outlet hole 22,1 so, draw, go into through hole 3,21 and cold-producing medium into and out of the circular passage 20,19 and on the main body of seal nipple 2, offer cold-producing medium respectively, inlet opening 22 is introduced through hole 21 with cold-producing medium and is communicated, cold-producing medium introducing through hole 21 enters circular passage 20 with cold-producing medium and communicates, and cold-producing medium enters circular passage 20 and communicates with cold-producing medium introducing hole 18; Fluid hole 1 is drawn through hole 3 with cold-producing medium and is communicated, and cold-producing medium is drawn through hole 3 and gone out circular passage 19 with cold-producing medium and communicate, and cold-producing medium goes out circular passage 19 and communicates with cold-producing medium fairlead 6.
As shown in Figure 2, the utility model is installed on the support 25 of indoor apparatus of air conditioner by pair of bearings 4,13, and fixing with support 25 again after being installed on seal nipple 2 on the fan shaft 5.The a pair of cold-producing medium liquid inlet and outlet pipe 26,24 that is connected with compressor of air-conditioning is communicated with liquid inlet and outlet hole 22,1 respectively.
When air-conditioning work, when promptly being in the refrigerating/heating state, compressor operating, cold-producing medium enters inlet opening 22 by cold-producing medium feed tube 26, and then through cold-producing medium introducing through hole 21, cold-producing medium enters circular passage 20, cold-producing medium is introduced hole 18, cold-producing medium groove 17, back cavity 9, enter fan blade 16, cold-producing medium is from the hollow cavity of first piece of fan blade 16 circulation successively to the hollow cavity of one piece of fan blade 16 of tail not, then from corresponding to the back cavity 9 of one piece of fan blade 16 of tail not successively through cold-producing medium groove 10, cold-producing medium fairlead 6, cold-producing medium goes out circular passage 19, fluid hole 1 is after cold-producing medium drain pipe 24 passes back into compressor.In this process, because the rotation of motor 14, one group of fan blade 16 is rotation status, one group of fan blade 16 had both played fan, the effect of the heat exchanger of having held concurrently again, therefore, heat exchange is under the dynamic agitation state to be carried out, and the more static heat exchanger that is provided with of its heat exchange property is more excellent.
Though use-case of the present utility model is only lifted the air-conditioning that has reached the wall-hanging structure, this does not also mean that cabinet type or other air-conditioning is not suitable for adopting technical solutions of the utility model.That is to say that the technical program is suitable equally on various air conditioners, all belongs in this programme scope of design.
