Abstract
The utility model discloses a heat exchanging tube for a tube-fin radiator, which consists of an inner tube (1) and an outer tube (2) closely sheathing the inner tube (1). Both ends of the inner tube (1) are provided with a protruding tube-plate joint section; and a plurality of through gutters (3) having the same length with the outer tube (2) is formed at the junction of the outer tube (2) and the inner tube (1). The heat exchanging tube for a tube-fin radiator is characterized in that if seepage occurs to the inner tube (1) when in use, the seepage water firstly flows into the through gutters (3) at the junction of the outer tube (2) and the inner tube (1), the outer tube (2) performs a protection function, and the seepage water flows out from the end by means of the through gutters (3), thereby effectively avoiding accidents resulted from that cooling water seeps into a motor due to the seepage of the inner tube (1)of the heat exchanging tube, and guaranteeing safe operation.
Description
Technical field
The utility model relates to radiator, especially relates to a kind of heat exchanger tube that is used for gilled tube radiator.
Background technology
Existing gilled tube radiator comprises Inlet and outlet water end cap, recirculation water end cap, heat exchanger tube, radiating fin and side plate, heat exchanger tube is common pipeline, the heat transferred cooling water that circulated air is drawn in the motor, cooling water flows in heat exchanger tube, and the radiating fin surface of thermal current outside heat exchanger tube flow through.Such structure, after gilled tube radiator used a period of time, if heat exchanger tube generation seepage, cooling water just can directly infiltrate motor, causes major accident easily.
The utility model content
Technical problem to be solved in the utility model is: a kind of heat exchanger tube that is used for gilled tube radiator is provided, and the cooling water that the use that this kind is used for the heat exchanger tube of gilled tube radiator can avoid heat exchanger tube generation seepage to cause infiltrates motor internal, thereby guarantees safety.
Solve this technical problem, the technical solution of the utility model is: a kind of heat exchanger tube that is used for gilled tube radiator, its by interior pipe with in closely being placed in the outer tube on the pipe form, the two ends of pipe all have the tube sheet joining section that stretches out in described, and described outer tube and interior pipe jointing place form many perforation tanks with the outer tube equal in length.
Described many connect the outer wall that tank is distributed in interior pipe.
The cross section of pipe and outer tube is ellipse in described.
A kind of heat exchanger tube that is used for gilled tube radiator of the utility model adopts such structure, in use, if seepage appears in interior pipe, the perforation tank of pipe and outer tube junction in percolating water at first can enter, outer tube can play protective action, flow out from the end by connecting tank then, the accident that the cooling water infiltration motor internal that so just can effectively avoid the interior pipe seepage of heat exchanger tube to cause brings can be guaranteed to use safely.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of heat exchanger tube that is used for gilled tube radiator, the outer tube 2 of pipe on 1 formed by interior pipe 1 and in closely being placed in, the two ends of interior pipe 1 all have the tube sheet joining section that stretches out, outer tube 2 and interior pipe 1 junction form many perforation tanks 3 with outer tube 2 equal in length, many connect tanks 3 be distributed in the outer wall of pipe 1.The outline of the interior pipe 1 of heat exchanger tube 12 and the cross section of outer tube 2 can be the cast of circle or oval or other cross sections.
As shown in Figure 3, gilled tube radiator comprises Inlet and outlet water end cap 6, many heat exchanger tubes 12, radiating fin 11, side plate 10, first tube sheet 4, second tube sheet 13, backing plate 9, cooling water runner 5, leakage alarm 8 and electric control part 7, every heat exchanger tube 12 all stretches into first tube sheet 4 near pipe 1 in the end of Inlet and outlet water end cap 6, one end outer tube 2 of every heat exchanger tube 12 close Inlet and outlet water end caps 6 all stretches into second tube sheet 13, backing plate 9 places between second tube sheet 13 and first tube sheet 4, first tube sheet 4, second tube sheet 13 and backing plate 9 form cooling water runner 5, and the perforation tank 3 of every heat exchanger tube 12 all communicates with cooling water runner 5.Leakage alarm 8 can be installed by hickey in the bottom of first tube sheet 4, and leakage alarm 8 stretches into cooling water runner 5.
The heat exchanger tube that is used for gilled tube radiator of this spline structure, in use, if seepage appears in interior pipe, the perforation tank of pipe and outer tube junction in percolating water at first can enter, outer tube can play protective action, flow out from the end by connecting tank then, the accident that the cooling water infiltration motor internal that so just can effectively avoid the interior pipe seepage of heat exchanger tube to cause brings can be guaranteed to use safely.
Claims (3)
