Description

The fixture of heat exchanger in the air-conditioner

The present invention relates generally to the fixture of heat exchanger in the air-conditioner, particularly relate to the improvement of fixture structure in this heat exchanger, with operational shock and the running noises of minimizing by the air-conditioner generation, and the leakage that prevents cold air.

With reference to Fig. 1, this is a decomposition phantom view that the air-conditioner of heat exchanger is arranged.In above-mentioned air-conditioner, heat exchanger 2 is fixed among the air-conditioning body 1 by a typical fixture.In other words, air-conditioning body 1 has a pair of fixed mount 3.Fixed mount 3 has fixed salient to divide 4 respectively, and this fixed mount 3 is contained on the wall inner surface of body 1.

Body 1 is held heat exchanger 2, and this heat exchanger 2 is contained in both sides to left and right sides stator (right stator 7 only is shown among the figure).Many blades 10 arranged vertical thick and fast prop up between left and right sides stator 7 and by left and right sides stator and hold.

The stator 7 of heat exchanger 2 has interior setting hook Button Handle 8, makes heat exchanger 2 enter fastener and fixed mount 3 engagements.Setting hook Button Handle 8 has a rectangle fastener hole 9 in each, such as the top that is fixed on respective fixation sheet 7 sides by welding.In above-mentioned air-conditioner, air-conditioning body 1 and heat exchanger 2 are to design like this, i.e. lacking slightly than the distance L between the fixed mount 3 of body 1 apart from l between the interior setting hook Button Handle 8 in the heat exchanger 2.

The fixed salient of each frame 3 divides 4 a hook end 5 is arranged, and this hook end 5 will flexibly hook in the rectangle fastener hole 9 of corresponding interior setting hook Button Handle 8 when frame 3 engagements of heat exchanger 2 and body 1.It is outside that fixed salient divides 4 end 5 the wedge of rising to the bait, thereby when frame 3 engagements of heat exchanger 2 and body 1, hook end 5 outwards hooks the rectangle fastener hole 9 of interior setting hook Button Handle 8.

Go to Fig. 2 and 3, heat exchanger 2 comprises many circulation pipe (not shown).Circulation pipe is horizontal-extending in heat exchanger 2, thereby their opposite end 6a (hereinafter referred to as " jag ") passes and the outstanding sheet 7 that is relatively fixed.In this case, the jag 6a of circulation pipe is fixed among many pipe fixing hole 7a of stator 7, and increases their external diameter, thereby after stator being assemblied on the heat exchanger 2, left and right sides stator 7 can not separate with heat exchanger 2 suddenly.

After being fixed on the jag 6a of circulation pipe on the stator 7, jag 6a is so interconnective by many semicircle tube connector 6, and the jag 6a of promptly per two adjacent arranged verticals interconnects by semicircle tube connector 6.At this moment, jag 6a can be best and the end welding of corresponding tube connector 6.

In above-mentioned heat exchanger fixing apparatus, body 1 and heat exchanger 2 are to design like this, and promptly the distance L between the interior setting hook Button Handle 8 of heat exchanger 2 is smaller a little than the distance L between the frame 3 of body 1.Like this, hook in the fastener hole 9 of fastener handle 8 and when making heat exchanger 2 with body 1 engagement at the hook end 5 that fixed salient is divided 4, flexiblely hook among the fastener hole 9 of fastener handle 8 up to hook end 5 till, the fixed salient of frame 3 divides 4 to be aduncate.Thereby, dividing 4 during at fixed salient with fastener handle 8 engagement of stator 7, fixed salient divides 4 outward pressures with outside unlatching fastener handle 8.

Under fastener handle 8 has been welded in situation on the left and right sides stator 7, the jag 6a of circulation pipe by continuously with they separately the end of tube connector 6 weld mutually.Thereby the high temperature spark that is produced when jag 6a is welded mutually with tube connector 6 also makes the fastener handle 8 of sheet 7 be heated, and therefore makes the zinc coating carbonization on the fastener handle 8.

When the jag 6a that makes tube connector 6 with circulation pipe continuously welded together, the welding torch (not shown) often bumped on interior setting hook Button Handle 8, thereby may make each fastener handle 8 change profile and size.Also have, when the jag 6a of tube connector 6 and circulation pipe welds together, the bending of setting hook Button Handle 8 in before the welding of pipe, causing inevitably.During 8 bendings of setting hook Button Handle, even when making curved hook Button Handle 8 be returned to original state by force, fastener handle 8 can not accurately be got back to its original state before the jag 6a that makes tube connector 6 with circulation pipe welds together and making in.

Above-mentioned heat exchanger fixing apparatus has following problems.

That is, when typical fixture is fixed on heat exchanger on the air-conditioning body, only utilized to hook the outside restoring force that fixed salient divides in the Button Handle of rising to the bait of stator on the heat exchanger, this restoring force attempts outwards to open stator.Like this, when the outside restoring force of dividing at fixed salient weakens, the said fixing device stably stationary heat exchangers on the air-conditioning body.

In addition, because the carbonization of zinc coating on the fastener handle of stator, may oxidation and gets rusty in its surface.Like this, As time goes on, rust staining may diffuse out air-conditioner, and getting rusty has weakened the fastener handle and made the fastener handle lost of life.

The fastener handle of heat exchanger and the fixed salient branch that body is put on the shelf may not have engagement tightly, and be loose thereby fixed salient divides with the engagement of fastener handle, and this makes that the engagement between heat exchanger and the air-conditioning body is loose.Because above-mentioned loose engagement may produce cold air at the air-conditioner run duration and reveal and running noises.Loose engagement also can cause damaged package between the time of shipment at air-conditioner.

An object of the present invention is to provide the device of heat exchanger in a kind of fixedly air-conditioner, can overcome above-mentioned problem and heat exchanger and air-conditioning body are fixed together, thereby make operational shock and running noises reduce to minimum, and prevent the leakage of cold air and improve the refrigeration of air-conditioner.

In order to achieve the above object, comprise according to heat exchanger fixing apparatus in the air-conditioner of a most preferred embodiment of the present invention: be contained in a pair of fixed mount of air-conditioning body inner surface on opposite side, each fixed mount has a fixed salient branch; At the left and right sides of heat exchanger both sides stator, each stator has many pipe fixing holes; And fastener handle piece that makes each stator and corresponding engagement.

With reference to Fig. 4, be depicted as and have the decomposition diagram that is fixed on the air-conditioner of heat exchanger on the air-conditioning body by fixture of the present invention.Heat exchanger 32 is fixed on the air-conditioning body 31 by following fixture.That is, air-conditioning body 31 has a pair of fixed mount 33.Fixed mount 33 has fixed salient respectively and divides 34, and this fixed mount is installed in the opposite side of body 31 upper wall inner surfaces.Each fixed salient divides 34 to have an inside hook at its end, thereby forms hook end 35.

Air-conditioning body 31 is holding in the palm heat exchanger 32, and this heat exchanger 32 has been loaded onto left and right sides stator 37 (right stator 37 only is shown among the figure) on the relative edge.Many heat-exchanger fins 60 are arranged between the left and right sides stator 37 and by left and right sides stator 37 thick and fast to be held.That is, the effect of two stators 37 is exactly to hold the heat-exchanger fin of heat exchanger 32 60.

Heat exchanger 32 also comprises many circulation pipe (not shown).Circulation pipe flatly extends in the inside of heat exchanger 32, thereby their two ends (not shown, hereinafter referred to as " jag ") passes and the stator 37 on outstanding both sides.In this case, the jag of circulation pipe is fixed in many pipe fixing hole (not shown) of stator 37, thereby, increased their external diameter.Therefore, after being contained in stator 37 on the heat exchanger 32, left and right sides stator 37 can not separate with heat exchanger 32 suddenly.

After the jag of circulation pipe was fixed on the two ends stator 37 in heat exchanger 32, jag interconnected by many semicircle tube connectors 36 by this way, and the jag that promptly every two-phase is faced arranged vertical connects by semicircle tube connector 36 mutually.At this moment, jag can be best and the end welding of corresponding tube connector 36.As shown in Figure 5, each stator 37 has many rectangle jacks 50.Jack 50 forms on each stator 37, thereby jack 50 is vertically separated with an interval and separates with tube connector 36.

The jack 50 of each stator 37 blocks fastener handle piece 40 so that fastener handle 40 is fixed on the stator 37.As following will the narration, carry out after the welding operation between the jag that is fixed on tube connector 36 and circulation pipe between fastener handle piece 40 and each stator 37.Each fastener handle piece 40 comprises many insertion ledges 41, will insert corresponding jack 50 on the stator 37, thereby fastener handle piece 40 is fixed on the stator 37.Fastener handle piece 40 also comprises a fastener annular section 42, with the fastener engagement of the hook end 35 of fixed projection 34 on generation and the respective fixation frame 33.Inserting ledge 41 interconnects by a support section 43 with fastener annular section 42.Insert ledge 41, fastener annular section 42 and support section 43 are combined into a monohook Button Handle piece 40.Fastener handle piece 40 is with right-angle bending four times, thereby forms as shown in Figure 5 trapezoidal.

Fig. 6 utilizes the fastener handle piece 40 of fixture of the present invention to be fixed on the amplification sectional view of the heat exchanger 32 on the air-conditioning body 31.As shown in the drawing, the insertion ledge 41 of each handle piece 40 tightly with respective fixation sheet 37 on jack 50 fixing, thereby ledge 41 closely contacts around the inner surface of jack 50 with stator 37.Here, preferably make each insertion ledge 41 of handle piece 40 that enough length is arranged, separate suddenly with the jack 50 of stator 37 to be suitable for preventing to insert ledge 41.

The fastener annular section 42 of each handle piece 40 has a rectangle fastener hole 42a, and fixed salient divides 34 hook end 35 to hook wherein.Rigid engagement for the hook end 35 that makes rectangle fastener hole 42a and ledge 34 preferably designs fastener hole 42a and projection 34 like this, makes the length of fastener hole 42a just in time be fit to the width of ledge 34.

The support section 43 of each handle piece 40 has the perhaps many contact ledges of inclined to one side contact devices 43a, and the altitude range of each ledge 43a is from 0.5mm to 5mm.When the handle piece 40 on being fixed on stator 37 meshes with respective fixation projection 34, contact ledge 43a will produce with the outer surface of stator 37 and contact.When inserting jacks 50 and make each handle piece 40 with stator 37 fixedly the time by inserting projection 41 since contact ledge 43a and between the support section 43 of the outer surface of stator 37 and handle piece 40 a formation gap " h ".Because the gap " h " that forms between stator 37 and support section 43, handle piece 40 has elasticity at contact ledge 43a place.

In the present invention, it is turning-ins that fixed salient divides the wedge of 34 hook end 35, thereby at the stator 37 of heat exchanger 32 during with 33 engagements of body 31 upper holders, hook end 35 is to hook inwards among the rectangle fastener hole 42a of handle piece 40.Be fixed on the distance between the handle piece 40 of stator 37 on the heat exchanger 32, more longer a little than the distance L between body 31 upper holders 33.

The operational effect of said fixing device will be in following narration.

In above-mentioned heat exchanger fixing apparatus, air-conditioning body 31 and heat exchanger 32 are such designs, promptly are fixed on the distance between the handle piece 40 on the stator 37 of heat exchanger 32, and be more longer slightly than the distance L between body 31 upper holders 33.Like this, hook among the fastener hole 42a of fastener handle piece 40 so that heat exchanger 32 when producing engagement at hook end 35 with body 31 with fixed projection 34, on the fixed mount 33 fixing outstanding 34 will be outwardly-bent as shown in phantom in Figure 6, till hook end 35 flexibly hooks among the fastener hole 42a of fastener handle piece 40.Therefore, divide 34 during with fastener handle piece 40 engagement of stator 37 at fixed salient, fixed salient divides 34 to have inwardly close inside restoring force.Because this inside restoring force, fixed salient are divided the 34 inside respectively flexiblely fastener annular sections 42 of extruded hook Button Handle piece 40.

On the other hand, hook buckled handle ring 40 its support section 43 have with fixed mount 33 on fixed salient divide the outwards power partially of 34 inside pressure in contrast.The outwards inclined to one side power of each handle piece 40 is caused by contact protrusion 43a on the support section 43, when the handle piece 40 of this projection 43a on being fixed on stator 37 divides 34 engagements with fixed salient, contacts with the outer surface of respective fixation sheet 37.In fixture of the present invention, fixed salient divides the outwards dynamic balance partially of 34 inside restoring force and handle piece 40, thereby can be maintained fixed sheet 37, the stationary state between handle piece 40 and the heat exchanger 32 more reliable and more rigidly.

In the present invention, the jag of circulation pipe under the situation that fastener handle piece 40 is not contained on the stator 37, the end welding of the outside of stator 37 and tube connector 36 separately continuously.Thereby, when the jag of weld cycle pipe continuously and their tube connectors 36 separately terminal, the not interference that causes by fastener handle piece 40.Therefore the time of the jag of weld cycle pipe and tube connector 36 saved, and the saving of time has improved the productivity ratio of air-conditioner.Further, during the welding of the jag of circulation pipe and tube connector 36 was not finished, fastener handle piece 40 was not contained on the respective fixation sheet 37 always, like this welding jag during with tube connector 36 the high temperature spark of generation can not contact with fastener handle piece 40.Like this, each fastener handle piece 40 does not have the profile that produces owing to welding operation and the variation of size.Because fastener handle piece 40 does not have the heating of high temperature spark, the zinc coating on the fastener handle piece 40 can carbonization.Therefore, fixture of the present invention has prevented the problem that produces owing to the possible carbonization of zinc coating.

As mentioned above, according to the present invention in the air-conditioner fixture of heat exchanger more reliable and more rigidly heat exchanger is fixed on the air-conditioning body.Therefore fixture has prevented the running noises that the vibration owing to heat exchanger produces.Fixture has also prevented the cold air leakage of air-conditioner, has therefore improved the refrigeration of air-conditioner.Another advantage of fixture is that this device is convenient to the welding of the jag and the tube connector of circulation pipe, thereby improves welding efficiency.

Though most preferred embodiment of the present invention is to disclose for the purpose of illustration, the one skilled in the art needs only the scope and spirit without prejudice to following public claim, can carry out various improvement, increase and alternative.
