Abstract
The utility model discloses a harmonica-shaped tube which comprises a body, inserted connection grooves and radiating grooves. The harmonica-shaped tube has the advantages that inner walls with the diameters gradually reduced from groove openings to the inner sides are arranged at the positions of the inserted connection grooves of the body, the longitudinal sections of the inner walls at the positions of the inserted connection grooves are in frustum shapes, the outer contours of the longitudinal sections of the inner walls at the positions of the inserted connection grooves are camber lines, the contact area between the harmonica-shaped tube and fins of a condenser is increased, and the connecting strength is easily improved; due to the inserted connection structure, leakage phenomena are effectively reduced, and the service life of the condenser is prolonged; the left end and the right end of the body are respectively provided with one radiating groove, a radiating plate is arranged in the middle of each radiating groove, the harmonica-shaped tube is radiated through the radiating grooves and the radiating plates, and the radiating effect of the harmonica-shaped tube is improved.
Description
Technical field
The utility model relates to a kind of harmonica-shaped tube, relates in particular to the harmonica-shaped tube in a kind of automotive air-conditioning condenser assembly field.
Background technology
The range of application of condenser is very wide, particularly in refrigerated air-conditioning system.Condenser is as one of main heat-transfer equipment, and the quality of its performance directly has influence on the overall work performance of device.Therefore, the strengthening of condenser diabatic process has obtained paying attention to more and more widely.In order to improve the overall performance of condensing plant, by each structure of modification of condenser being carried out to strengthening heat transfer to improve the efficiency of condenser, become a kind of trend of domestic and international condenser development.In traditional condenser, harmonica-shaped tube adopts welding manner and simple in structure mostly, and this assembly does not have radiator structure, and the radiating effect of harmonica-shaped tube is not good.
Summary of the invention
The utility model is intended to invent a kind of good heat dissipation effect and harmonica-shaped tube easy to connect.
A kind of harmonica-shaped tube comprises main body, inserting groove and radiating groove, the left and right two ends of main body are respectively provided with a radiating groove, described radiating groove middle part is provided with a heat sink, and main body one side is provided with some inserting grooves, and the inserting groove place of described main body is provided with from the notch inwall of undergauge gradually to the inside.
Preferably, the inwall longitudinal section at described inserting groove place is taper type.
Preferably, the outer contour of its longitudinal section of inwall at described inserting groove place is camber line.
Preferably, described heat sink height is identical with radiating groove height.
Preferably, total 55-65 of described inserting groove.
The beneficial effects of the utility model are:
1. the inserting groove place of main body is provided with from the notch inwall of undergauge gradually to the inside, the inwall longitudinal section at inserting groove place is taper type, the outer contour of its longitudinal section of inwall at inserting groove place is camber line, increase the contact area of harmonica-shaped tube and condenser fin, be conducive to improve bonding strength, this connected structure has effectively reduced Seepage, has increased the service life of condenser;
2. the left and right two ends of main body are respectively provided with a radiating groove, and radiating groove middle part is provided with heat sink, and harmonica-shaped tube dispels the heat by radiating groove and heat sink, has improved the radiating effect of harmonica-shaped tube.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the interior wall construction schematic diagram at harmonica-shaped tube inserting groove of the present utility model place.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, structure of the present utility model is described further.
As shown in Figure 1, 2, a kind of harmonica-shaped tube comprises main body 1, inserting groove 2 and radiating groove 3, the left and right two ends of main body 1 are respectively provided with a radiating groove 3, described radiating groove 3 middle parts are provided with a heat sink 4, main body 1 one sides are provided with some inserting grooves 2, inserting groove 2 places of described main body 1 are provided with from the notch inwall of undergauge gradually to the inside, the inwall longitudinal section at inserting groove 2 places is taper type, the outer contour of its longitudinal section of inwall at inserting groove 2 places is camber line, heat sink 4 height are highly identical with radiating groove 3, total 55-65 of inserting groove 2.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection domain of the present utility model.
