Description
Technical field:
The utility model relates to air-conditioning technical field, in particular to a kind of heat exchanger.
Background technology:
In prior art, side plate poling hole inwall and the heat exchanger tube close contact of air-condition heat exchanger, in the time of air-conditioning unit operation, the collector and the branched pipe that are connected on compressor of air conditioner can produce larger impulsive force and vibration, so, and the heat exchanger tube vibration being connected with branched pipe, wall friction in the heat exchanger tube of vibration and side plate poling hole, easily make heat exchanger tube break, cause the generation of leakage phenomenon, its consequence is that unit can not normally move.
Utility model content:
The technical problem that the utility model solves: in the time of air-conditioning unit operation, be connected to impulsive force and the vibration that collector on compressor of air conditioner and branched pipe produce and make wall friction in heat exchanger tube and side plate poling hole, cause heat exchanger tube to break.
The utility model provides following technical scheme: a kind of heat exchanger, comprise the fin that offers through hole, offer the side plate in side plate hole, heat exchanger tube, branched pipe, collector, described heat exchanger tube is connected in series by U-shaped elbow by multiple U-shaped heat exchanger tube elements, described heat exchanger tube two ends are connected with branched pipe, described branched pipe is connected with collector, described U-shaped heat exchanger tube element interts in the through hole of fin, described U-shaped heat exchanger tube element two ends are by described side plate hole, the diameter in the side plate hole that one end of the described U-shaped heat exchanger tube element being connected with branched pipe is passed through is greater than the pipe external diameter of described U-shaped heat exchanger tube element.
By technique scheme, the diameter in the side plate hole of passing through due to one end of the U-shaped heat exchanger tube element being connected with branched pipe is greater than the pipe external diameter of described U-shaped heat exchanger tube element, so, when air-conditioning unit operation, make U-shaped heat exchanger tube element also produce vibration although be connected to impulsive force and the vibration that collector on compressor of air conditioner and branched pipe produce, but, wall friction in the side plate hole that U-shaped heat exchanger tube element but can not pass through with it, naturally can not cause heat exchanger tube to break and leakage of refrigerant, to ensure the normal operation of unit.In addition, because U-shaped heat exchanger tube element interts in the through hole of fin, the vibration that U-shaped heat exchanger tube element produces will pass to fin, and fin also produces vibration, but diameter be greater than the side plate hole of the pipe external diameter of U-shaped heat exchanger tube element can be to the generation of vibration cushioning effect of fin.
Apart from the above, technical scheme described in the utility model also has following beneficial effect:
(1) the easily quick side plate hole place that is greater than the pipe external diameter of U-shaped heat exchanger tube element by described diameter of swollen head in the time of heat exchanger tube expand tube, swollen head in heat exchanger tube when dilating outward, heat exchanger tube can obviously swell and constantly shrink, when swollen head is greater than the side plate hole place of pipe external diameter of U-shaped heat exchanger tube element by described diameter, can not be stuck or heat exchanger tube is pulled;
(2) interting when U-shaped heat exchanger tube element, U-shaped heat exchanger tube element easily by described diameter than the large side plate hole of U-shaped heat exchanger tube element tube external diameter, be difficult for by side plate hole stifled (gear) firmly, more can not pulled by side plate hole;
(3) in processing heat exchanger process, save the stretching process in the described side plate hole larger than U-shaped heat exchanger tube element tube external diameter, improved production efficiency;
(4) than prior art, process and describedly will remove the more material of side plate than the large side plate hole of U-shaped heat exchanger tube element tube external diameter, therefore, adopt the technical solution of the utility model can alleviate side plate weight, cut down finished cost.
As further improvement of the utility model, the diameter value in the side plate hole that one end of the described U-shaped heat exchanger tube element being connected with branched pipe is passed through is greater than 2.5～3.0 millimeters of the pipe external diameter values of described U-shaped heat exchanger tube element.
As further improvement of the utility model, Wei Ping hole, side plate hole or flanging bore that one end of the described U-shaped heat exchanger tube element being connected with branched pipe is passed through.If flanging bore, the flange direction of described flanging bore is same as the direction of the interspersed flanging bore of U-shaped heat exchanger tube element, and so the reason of design is: the flange bending place of flanging bore can produce circular arc, can facilitate U-shaped heat exchanger tube element to pass through.
As further improvement of the utility model, the side plate hole inwall that one end of the U-shaped heat exchanger tube element that described and U-shaped elbow is connected is passed through and U-shaped heat exchanger tube element close contact.As preferably, the side plate hole that one end of the U-shaped heat exchanger tube element that described and U-shaped elbow is connected is passed through is stretchable holes, and the stretching of described stretchable holes is highly 2.0～3.0 millimeters.So, can increase the contact area of heat exchanger tube and side plate stretchable holes, not only can prevent between heat exchanger tube and side plate stretchable holes loosening, side plate, fin and heat exchanger tube are connected in aggregates, and can reduce and the vibration of the heat exchanger tube of elbow coupling part, make heat exchanger tube be difficult for breaking and causing leakage because of vibration.
