Description
Technical field
The present invention relates to a kind of heat transfer unit (HTU), particularly relate to a kind of tube-fin type radiator based on heat medium temperature.
Background technology
Tube-fin type radiator is a kind of common close-coupled radiator, and its fuse is combined by flat tube and the fin be welded on flat tube, because of the characteristic that it is efficient, compact, light and handy, is widely used as vehicle-mounted water tank and various oil radiator.To the tube-fin type radiator of this compact conformation, because flat tube configuration is relatively simple, therefore fin configuration serves crucial decisive role to the heat exchange of whole radiator and resistance performance.Common fin configuration comprises staggered, venetian blind type, corrugated, perforating type, straight formula etc.There are some researches show, relative to plain fin, use offset strip fin that the coefficient of heat transfer can be made higher, but meanwhile, resistance coefficient also can increase greatly, thus amplify the overall resistance of cooling system.
Because enough coolings are the prerequisites ensureing engine work; in order to ensure reliably; when designing radiator; the maximum radiating requirements of usual meeting needed for work selects fin configuration; and under the operating mode that radiating requirements is lower, heat medium temperature is relative with flow lower, the heat-sinking capability of cold side fin redundancy will cause the waste of resistance dissipative; engine temperature even also may be made too low, affect efficiency of combustion.If according to the different operating modes of engine, for different radiating requirements, multi-form radiating fin can be adopted, the condition that engine stabilizer runs can not only be met, and significantly will save resistance dissipative.
Summary of the invention
The object of the invention is to the waste for prior art heat-sinking capability under low heat emission operating mode, a kind of tube-fin type radiator based on heat medium temperature is provided.
The object of the invention is to be achieved through the following technical solutions: a kind of tube-fin type radiator based on heat medium temperature, comprises thermal medium entrance, head tube connector, fin, stationary pipes, motion pipe, motion pipe upper extending section, motion pipe lower extending section, thermal medium outlet, afterbody tube connector;

Fin is the cascaded structure of multiple " bow " font, is arranged in parallelly arranged between stationary pipes and motion pipe, and adjacent two fins are respectively with stationary pipes with move to manage and fix; Thermal medium enters into head tube connector by thermal medium entrance, is then entered in each stationary pipes and motion pipe by dispersion; When heat medium temperature is too high, motion pipe upper extending section is expanding by under heat effect, make motion pipe racks move the fin be fixed on motion pipe to move down, the fin on motion pipe and the adjacent fin stagger arrangement of being fixed in stationary pipes are come, and form stagger arrangement type fin.
Further, above-mentioned tube-fin type radiator also comprises motion pipe-in-pipe, and described motion pipe-in-pipe is enclosed within outside motion pipe upper extending section, and motion pipe-in-pipe upper end is fixed on head tube connector, and lower end is unsettled.
The present invention has following technique effect:
1. energy saving: the change that can realize fin configuration according to radiator heat side temperature, for different engine operating conditions, while guaranteeing heat exchange property, can control the resistance dissipative of radiator under low heat emission operating mode preferably.
2. applicability: this method is simple to operate, can be applied to the tube-fin type radiator of multiple automobile-used solution-air heat exchange.
3. be convenient to integration and modularized design: the program remains uniform in the design and production of fuse entirety, by pressure telescopic section according to temperature automatic adjustment position, thus changes fin configuration.Therefore assembling is simple, is applicable to the combinations matches optimization of upstream and downstream radiator in cooling system for vehicle.
4. the method use cost is low, processing technology is simple.

Detailed description of the invention
Below in conjunction with Figure of description, the invention will be further described.
As shown in Figure 1, a kind of tube-fin type radiator based on heat medium temperature of the present invention, comprises thermal medium entrance 1, head tube connector 2, fin 3, stationary pipes 5, motion pipe 6, motion pipe upper extending section 7, motion pipe lower extending section 8, thermal medium outlet 9, afterbody tube connector 10; Thermal medium entrance 1 is connected with head tube connector 2, and thermal medium outlet 9 is connected with afterbody tube connector 10; The two ends of stationary pipes 5 are connected with afterbody tube connector 10 with head tube connector 2 respectively, and motion pipe 6 upper end is connected with head tube connector 2 by motion pipe upper extending section 7, and motion pipe 6 lower end is connected with afterbody tube connector 10 by motion pipe lower extending section 8; Stationary pipes 5 and motion pipe 6 are alternately arranged successively.Described stationary pipes 5, motion pipe 6 are flat tube.
As shown in Figure 2, fin 3 cascaded structure in multiple " bow " font, as shown in Figures 3 and 4, fin 3 is arranged in parallel, and is arranged between stationary pipes 5 and motion pipe 6, and adjacent two fins 3 respectively with the stationary pipes 5 of both sides and motion pipe 6 fixing.
As shown in Figure 8, tube-fin type radiator also comprises motion pipe-in-pipe 11, and described motion pipe-in-pipe 11 is enclosed within outside motion pipe upper extending section 7, and motion pipe-in-pipe 11 upper end is fixed on head tube connector 2, and lower end is unsettled.Motion pipe-in-pipe 11 can prevent motion pipe upper extending section 7 outwardly under the pressure effect of thermal medium.
Motion pipe upper extending section 7 is made up of thermally sensitive thermal expansion material; Motion pipe lower extending section 8 is made up of the retractable material that elasticity is good, has certain elastoplasticity.Under the operating mode that radiating requirements is lower, because heat medium temperature is lower, motion pipe upper extending section 7 and motion pipe lower extending section 8 are in stable state, and motion pipe fin and stationary pipes fin form straight fin form; (Fig. 5), when radiating requirements is larger, heat medium temperature is very high, motion pipe upper extending section 7 expands under heat expansion effect, motion pipe 6 is made to drive the fin 3 be fixed on motion pipe 6 to move down (Fig. 6), fin 3 on motion pipe 6 comes with adjacent fin 3 stagger arrangement of being fixed in stationary pipes, form stagger arrangement type fin (Fig. 7), length due to motion pipe lower extending section 8 is 1/2 of finned length d, therefore the maximum displacement of motion pipe is 1/2 of finned length d, has both reached maximum radiating effect.
When cover has motion pipe-in-pipe 11, motion pipe upper extending section 7 can not convex (Fig. 8), the move distance on vertical direction larger (being less than 1/2 of finned length d), and effect is more obviously good; The overall heat exchange ability of radiator is promoted greatly, realizes enhanced heat exchange.
Therefore, the tube-fin type radiator that the present invention proposes, according to the temperature level of the thermal medium of radiator (deep fat or water), can realize the adjustment to fin distribution form.Under the operating mode that radiating requirements is higher, form the stagger arrangement type fin that coefficient of heat transfer is higher; And under the operating mode that radiating requirements is lower, keep the form of plain fin; Thus the resistance dissipative rationally reduced under low heat emission operating mode, improve radiator operating efficiency.
