Abstract
The invention offers a kind of heat exchanger. Its structure comprises secondary refrigerant pipe in which the secondary refrigerant is flowed, many cooling fins fixed on the secondary refrigerant pipe, fan electromotor and air blow fan forcibly transported the outside air to the fan secondary refrigerant pipe and the cooling fins. The secondary refrigerant pipe is dropped down the direction of air exhaust of the air blow fan and inclined with the ground. The advantage of the invention is that the secondary refrigerant pipe is inclined to make the thickness of the liquid state secondary refrigerant form to uniform in the up-down part of the secondary refrigerant pipe; the exchange capacity of the liquid state secondary refrigerant flowed in the secondary refrigerant pipe and gaseous heat is increased; in the heat exchanger with certain space, the flow path of the secondary refrigerant is only changed to sharply improve the heat exchange performance.
Description
Technical field
The invention relates to the invention of heat exchanger, particularly be the invention that is applicable to heat exchanger on refrigerator or the air conditioner.
Background technology
Usually the refrigerant of refrigerator and air conditioner is through the cool cycles process of compression condensation-expansion-evaporation and produce cold air, makes food fresh or make the device of indoor refrigeration.
As shown in Figure 1, be the structure chart of the cooling heat exchanger that uses when cooling off of the refrigerant of the HTHP of discharging from the compressor that is arranged in equipment such as refrigerator and air conditioner, condensate and heat exchanger 3 includes: the refrigerant pipe 3a that is become S shape by the level alternating bending; The vertical a plurality of fin 3b that are provided with and play the effect of expansion heat exchange area on refrigerant pipe 3a.
Above-mentioned condensate and heat exchanger 3 be in order successfully to finish condensation process, disposes Air Blast fan 1 and fan electromotor 2 in a side of condensate and heat exchanger 3.
Gas coolant from compressor (not looking the figure) discharge HTHP, refrigerant pipe 3a along condensate and heat exchanger 3 flows, at this moment, by Air Blast fan 1 when condensate and heat exchanger 3 sides are blown, the gas coolant of flow air and refrigerant pipe 3a carries out heat exchange, is cooled to the liquid coolant of normal temperature high voltage state along the gas coolant of the mobile HTHP of refrigerant pipe 3a.
Fig. 2 is the condensation process that takes place among the refrigerant pipe 3a of the above-mentioned condensate and heat exchanger 3 of explanation.As shown in Figure 2, to be refrigerants flow along refrigerant pipe 3a existing condensate and heat exchanger 3, when refrigerant during from the gaseous state liquefy, under the effect of gravity, gathers a lot of liquid refrigerants below refrigerant pipe 3a.And then the thickness a that the liquid refrigerants below the refrigerant pipe 3a the occurs phenomenon bigger than the thickness b of top liquid refrigerants, therefore, under the situation in uneven thickness of liquid refrigerants, thereby the coefficient of heat conduction heat exchange performance that diminishes is reduced.
Have heat exchanger in order to improve heat exchange performance, the general rotating speed or the big or small size that increases air quantity or increase condensate and heat exchanger that increase blowing fan 1 of adopting enlarges schemes such as heat exchange area.
But, the scheme of above-mentioned raising heat-conductive characteristic, existing increases noise when increasing power consumption, and increases the size of heat exchanger, and then increases the product overall dimensions.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, a kind of size that does not increase the size or the rotating speed of Air Blast fan or do not increase heat exchanger is provided, but improve the structure of heat exchanger, the thickness of the refrigerant that flows in pipe is become evenly, thereby can improve the heat exchanger of heat exchange performance.
The technical scheme that solves the problems of the technologies described above is: a kind of heat exchanger, be equipped with the refrigerant pipe of the refrigerant that flows in its structure includes; Be fixed on a plurality of fin on the refrigerant pipe; To the Air Blast fan and the fan electromotor of refrigerant pipe and fin forced conveyance extraneous air, described refrigerant pipe is provided with along Air Blast fan air draft direction and ground inclination ground.
The invention has the beneficial effects as follows: refrigerant pipe of the present invention tilts, thereby the top and the bottom liquid refrigerants thickness of refrigerant pipe is formed evenly, the liquid refrigerants that flows in the refrigerant pipe and the heat-exchange capacity of gaseous state increase, in having the heat exchanger of certain space, only change its refrigerant flow, just can increase substantially its heat exchange performance.

The specific embodiment
The invention provides a kind of heat exchanger, the refrigerant pipe of the refrigerant that flows is housed in its structure includes; Be fixed on a plurality of fin on the refrigerant pipe; To the Air Blast fan and the fan electromotor of refrigerant pipe and fin forced conveyance extraneous air, described refrigerant pipe 301 is provided with along Air Blast fan 1 air draft direction and ground inclination ground.
The inclination angle of described refrigerant pipe 301 is that 40 degree are to the scope of 50 degree.
Described fin 302 is to be provided with in horizontal direction with ground.
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail:
Fig. 3 is the structure of condensate and heat exchanger of the present invention, as shown in Figure 3, dispose the Air Blast fan 1 and the fan electromotor 2 of heat exchanger 30 side forced conveyance extraneous airs in a side of condensate and heat exchanger 30, condensate and heat exchanger 30 forms with ground inclination towards the refrigerant pipe 301 of Air Blast fan 1 side.Refrigerant pipe 301 is to be connected on the compressor (not looking among the figure), and the refrigerant of the HTHP of discharging from compressor portion within it flows.
The fin 302 of above-mentioned condensate and heat exchanger 30 is to make wind pushing air form slick and sly flowing, and is fixed in horizontal direction on the refrigerant pipe 301 with ground, to unrestricted in its orientation.
As above the refrigerant pipe 301 of the condensate and heat exchanger of the present invention 30 of Gou Chenging is to be the formation that tilts towards Air Blast fan 1, and therefore, the thickness of the liquid refrigerants in the refrigerant pipe 301 is uniform.
Promptly, as shown in Figure 4, the air that the gaseous coolant of the HTHP of inflow refrigerant pipe 301 is carried by Air Blast fan 1 carries out the liquid refrigerants that heat exchange becomes high pressure, at this moment, because the refrigerant pipe 301 relative with Air Blast fan 1 is obliquely installed, the bottom a large amount of liquid refrigerants of generation deposits to downside under the gravity effect in refrigerant pipe 301, and the liquid refrigerants that refrigerant pipe 301 tops generate lets droop owing to surface tension diminishes, and therefore the thickness of the liquid refrigerants on refrigerant pipe 301 bottoms and top can be formed uniformly.
Because the upper and lower side thickness at the liquid refrigerants of refrigerant pipe 301 internal flows forms uniformly, thereby can improve the effect that the heat conduction between liquid state and gaseous state forms.Such result is the paper according to S.Fiedler and H.Auracher: during adverse current in the minor diameter tipping tube with the heat exchange of R-134a in the data pointed out draw.
Fig. 5 is the inclination of refrigerant pipe 301 and the curve map that the coefficient of heat conduction changes.When the tiltangle of refrigerant pipe 301 at about 40 degree when 50 degree end, the plain Re of Reynolds coefficient of heat conduction Nu under 75 and 100 condition separately increases gradually, is the tendency that reduces gradually after again.
The inclination angle of refrigerant pipe 301 forms about 40 degree to 50 degree situations, and is big compared with the coefficient of heat conduction of previous heat exchanger, finally can also can improve heat exchange performance under identical condition at rotating speed that does not increase Air Blast fan 1 or power.
