Description

A kind of novel gas turbine inter cooler plate-fin heat exchanger fluidal texture

Technical field

The utility model relates to plate-fin heat exchangers, and in particular to a kind of novel gas turbine inter cooler plate fin heat-exchanging Device fluidal texture.

Background technique

Plate-fin heat exchanger is compact-sized, heat exchange efficiency is high, is widely applied and space flight and aviation, petrochemical industry, refrigeration, ship Equal fields.

Existing heat exchanger core body is mostly cuboid-type, and coolant media flows to the other end from one end of core, and heating agent is from core Side is flowed through, and this structure interface is big, good effect of heat exchange；Since core thickness is small, heat dissipation reaction speed is fast.But this heat dissipation Mode is smaller to the utilization rate of refrigerant.

Summary of the invention

In view of the deficiencies of the prior art, the utility model provides a kind of novel gas turbine inter cooler plate-fin heat exchanger Fluidal texture.

A kind of novel gas turbine inter cooler plate-fin heat exchanger fluidal texture, it is characterised in that: including cuboid Plate-fin radiating core, the vertical refrigerant layer of several layers is equipped in the radiating core, is equipped between the refrigerant layer Hot-fluid layer；At least four layers of refrigerant passage arranged up and down are equipped in every layer of refrigerant layer, the neighbouring refrigerant is logical Road is sequentially connected end to end in turn logical and makes fluid S-shaped flowing between the refrigerant passage.

Further are as follows: the refrigerant passage is four layers, and the refrigerant inlet and refrigerant exit are located at the radiating core The same side；It is connected between the adjacent refrigerant passage by through-hole, the refrigerant inlet and the through-hole are located at the refrigerant Opposite both ends on channel.

The utility model has the beneficial effects that this structure makes refrigerant S-shaped flowing between refrigerant passage layer, work as air When by radiating core, the refrigerant temperature in refrigerant passage layer described in the direction from air inlet to air outlet is lower and lower, refrigerant Increase and increase the utilization rate of refrigerant with the heat exchange stroke of air, simultaneously because at air outlet in refrigerant passage refrigerant temperature It spends lower, increases the cooling effect of air at air outlet.

Specific embodiment

It elaborates with reference to the accompanying drawing to the utility model.It should be noted that a left side in the example of the utility model, In, the positional terms such as right, upper and lower, be only relative concept or be to refer to the normal operating condition of product each other, without answering This is considered restrictive.

As depicted in figs. 1 and 2, a kind of novel gas turbine inter cooler plate-fin heat exchanger fluidal texture, including it is rectangular The plate-fin radiating core of the bodily form, is equipped with the vertical refrigerant layer of several layers in the radiating core, between the refrigerant layer Equipped with hot-fluid layer；At least four layers of refrigerant passage arranged up and down are equipped in every layer of refrigerant layer, neighbouring is described cold Matchmaker channel 2 is sequentially connected end to end in turn logical and makes fluid S-shaped flowing between the refrigerant passage 2；

Wherein, the refrigerant passage 2 is four layers, and the refrigerant inlet 11 and refrigerant exit 12 are located at the radiating core 1 The same side, refrigerant inlet 11 is located at the lower part of radiating core side, and refrigerant exit 12 is located at the top of radiating core side, dissipates The upper surface of hot core is into hot gas face, and the lower end surface of radiating core is hot gas face；By leading between the adjacent refrigerant passage 1 Hole connection, the refrigerant inlet 11 are located at both ends opposite on the refrigerant passage 2 with the through-hole.It is logical in the refrigerant Heat-conducting plate is connected between the inner wall up and down in road 2.

Working principle of the utility model is: as shown in connection with fig. 2, entering the entrance in refrigerant passage at C for refrigerant, being at B Refrigerant goes out the outlet of refrigerant passage, enters the entrance of radiating core at A for hot-air, is that cold air goes out going out for radiating core at B Mouthful；Refrigerant S-shaped flowing between 2 layers of refrigerant passage, when air passes through radiating core, to cold described in the direction at D from A Refrigerant temperature in 2 layers of matchmaker channel is lower and lower.

The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this The principle of utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various change And improvement, these various changes and improvements fall within the scope of the claimed invention.The utility model requires protection scope It is defined by the appending claims and its equivalent thereof.
