Detailed Description
The invention is described in detail below with reference to the figures and examples.
The invention discloses a composite compact heat exchanger core, which comprises an end plate 1, a gas heat exchange unit 3 and a liquid heat exchange unit 2; the gas heat exchange units 3 and the liquid heat exchange units 2 are alternately stacked and arranged between the end plates 1; the flow channel of the liquid heat exchange unit 2 is larger than the heat exchange channel of the gas heat exchange unit 3. The height of the flow channel of the liquid heat exchange unit 2 can be adjusted according to the physical properties of cold and hot fluids and the requirements of use working conditions.
The flow channel of the liquid heat exchange unit 2 is provided with a fin 4 capable of improving the structural strength.
One embodiment of the invention is shown in FIG. 1, the fins are individual fins of a plurality of airfoil shapes (shown in FIG. 4 a) or S-shapes (shown in FIG. 5 a); the independent fins are arranged on the fin plates, and flow channels are formed between the fin plates and the gas heat exchange unit 3. The cross section of the flow channel is rectangular, and the independent fins support the liquid heat exchange unit 2, so that the structural strength is improved.
In this embodiment, the fins may be distributed in parallel at equal intervals as shown in fig. 4a and 5 a. Alternatively, the fins may be staggered and equally spaced as shown in fig. 4b and 5 b.
The airfoil type and the S-shaped fin are arranged in parallel to the flow direction of the fluid in the hot passage (flow passage of the liquid heat exchange unit).
In a second embodiment of the present invention, as shown in fig. 2, the fins are fins having a continuous cross-section in the shape of a "cross-section"; the inverted V-shaped fins are arranged on the partition plate 5 and can be directly placed or fixedly or movably connected. A flow passage is formed between the partition plate 5 and the gas heat exchange unit 3. The whole flow passage is divided by the inverted V-shaped fins.
In both embodiments, the fin height is equal to the channel height. After the fluid medium enters the fin plate channel, the fluid medium is disturbed by the fins, so that the flow boundary layer and the thermal boundary layer are broken and recombined, the heat exchange is enhanced, the heat exchange performance is improved, in addition, the equal-height fin structure can play a role in bearing and supporting the cold fluid through hole, and the strength of the heat exchanger is improved.
In a third embodiment of the present invention, as shown in fig. 3, the flow channel of the liquid heat exchange unit 2 is formed by splicing channels respectively arranged on two heat exchange plates. In this embodiment, the channel is formed by splicing two semicircular channels, and the size of the channel is larger than that of the heat exchange channel of the gas heat exchange unit 3.
In the three embodiments, in order to increase the heat exchange area of the working medium with poor heat transfer performance, the number of the heat exchange channels of the gas heat exchange unit 3 is multiple, and single-layer parallel arrangement or multi-layer parallel arrangement can be selected according to requirements. When the single-layer parallel arrangement is performed, the gas heat exchange unit 3 only needs to be provided with one layer of heat exchange plates, and when the multiple layers of parallel arrangement are performed, the gas heat exchange unit 3 needs to be provided with multiple layers of heat exchange plates to be stacked. The structure increases the heat exchange area of unit volume, and is beneficial to the working medium with poor heat transfer performance to flow through the channel of the gas heat exchange unit 3 for heat exchange. The heat exchanger core with the structure can reduce the volume of the core of the heat exchanger under the condition of the same heat exchange power.
The heat exchange channels of the gas heat exchange unit 3 are parallel straight channels or S-shaped channels or Z-shaped channels, and the adjacent heat exchange channels are equal in distance. Wherein, the S-shaped channel or the Z-shaped channel can be periodically and continuously distributed. The heat exchange channel is formed by etching technology, and is a millimeter-scale semicircular cross section channel in the embodiment. In addition, according to actual requirements, the cross section of the heat exchange channel can be any one of a circle, a semicircle, an ellipse, a semiellipse, a triangle, a rectangle and a trapezoid.
In order to ensure the heat exchange effect, the fluid (cold fluid) in the heat exchange channel of the gas heat exchange unit 3 and the fluid (hot fluid) in the flow channel of the liquid heat exchange unit 2 can be selected to perform concurrent or countercurrent heat exchange as required.
In the three embodiments, the heat exchanger core is a cube, and the cross section of the heat exchanger core can be set arbitrarily according to the requirements of use conditions. When a heat exchanger with compact structure and small volume is pursued, the cross-sectional dimension of the heat exchanger core perpendicular to the flow direction can be arranged to be close to a square. The fluid inlet and outlet of the gas heat exchange unit 3 and the fluid inlet and outlet of the liquid heat exchange unit 2 can be arranged on any two pairs of opposite sides of the heat exchanger core.
For example, 1, according to the use requirement, the inlet and outlet mode of the core body of the heat exchanger is set to a concurrent flow mode, wherein the inlet and outlet of the hot fluid channel are arranged on the top surface and the bottom surface of the heat exchanger, and the inlet and outlet directions of the cold fluid are arranged on any two opposite side surfaces of the heat exchanger.
2. According to the use requirement, the cold and hot fluid flowing mode of the heat exchanger is set to be a forward flow mode, wherein the inlet and the outlet of the hot fluid channel are arranged on any two opposite side surfaces of the heat exchanger, and the inlet and the outlet of the cold fluid are arranged on the top surface and the bottom surface of the heat exchanger.
3. According to the use requirement, the flow mode of cold and hot fluid of the heat exchanger is set to be a counter flow mode, wherein an inlet and an outlet of a hot fluid channel are arranged on the top surface and the bottom surface of the heat exchanger, and the inlet and the outlet of a cold fluid are arranged on any two opposite side surfaces of the heat exchanger.
4. According to the use requirement, the flow mode of cold and hot fluid of the heat exchanger is set to be a counter flow mode, wherein the inlet and the outlet of the hot fluid channel are arranged on any two opposite side surfaces of the heat exchanger, and the inlet and the outlet of the cold fluid are arranged on the top surface and the bottom surface of the heat exchanger.
In the above three embodiments, the heat exchange plates (etching plates) of the gas heat exchange unit 3, the heat exchange plates (i.e., partition plates or fin plates) of the liquid heat exchange unit 2, and the end plates 1 are welded by a diffusion welding process.
According to the invention, through the arrangement mode of alternately stacking the gas heat exchange units 3 and the liquid heat exchange units 2, the flow area of the channel on one side is increased, so that the heat exchanger is suitable for avoiding the problem of blockage of the flow channel when impurities such as particles exist in the working medium, the service life of the heat exchanger is prolonged, the flow resistance of fluid can be reduced, and the heat exchange effect is improved.
The gas heat exchange unit 3 can be stacked by adopting a plurality of layers of micro-channel etching plates, the heat exchange requirement when a working medium with poor heat transfer performance flows through the channel of the gas heat exchange unit is met, heat can be sufficiently transferred, the core body volume of the heat exchanger can be reduced under the condition of the same heat exchange power, and the heat exchange efficiency is improved.
