Definitions
- the invention relates to heat exchangers for air conditioning and heat pump applications.
- it relates to heat exchangers for use in automotive industry.
- AC mode air conditioning mode
- the heat exchanger works as an ordinary condenser.
- the refrigerant at the inlet at a typical operation point is in gaseous state and needs to be cooled inside the core in order to deliver liquid, subcooled refrigerant at outlet.
- the cores are usually configured in manner ensuring that number of tubes in first pass is significantly greater than number of tubes in second pass.
- Number of tubes in second pass may be usually 8-12 when total number of tubes may be equal or above 60 for some specific application.
- This solution is beneficial, because it allows decrease in pressure drop in first pass, where density of refrigerant is small and consequently the volumetric flow is significant.
- the refrigerant is condensed, i.e. it is fluid or mostly fluid, while its density is significantly higher and in connection to that volumetric flow is also significantly lower.
- heat exchangers adapted to work in a so-called HP mode (heat pump mode).
- HP mode the temperature of refrigerant at inlet is lower than temperature of air flowing through the core.
- Refrigerant is heated inside core and in the second pass temperature of refrigerant is higher and due to that density is smaller than in the first pass.
- the object of the invention is, among others, a heat exchanger comprising a first manifold and a second manifold connected by a bundle of tubes, configured to provide an inlet pass, an outlet pass and an intermediate pass for a heat exchange fluid, characterized in that the heat exchanger comprises controlling means adapted to switch between a first state, in which co-flow of the heat exchange fluid in the outlet pass and the intermediate pass with counterflow in the inlet pass is enabled, and a second state in which co-flow of the heat exchange fluid in the inlet pass and the intermediate pass with counterflow in the outlet
- the heat exchanger is further comprising an inlet port associated with the inlet pass and an outlet port associated with an outlet pass, wherein both are located on the first manifold.
- the flow between the inlet pass, the intermediate pass and the outlet pass is blocked within the second manifold, wherein the heat exchanger further comprises an outside channel, the outside channel being adapted to receive the fluid from and distribute the fluid to the inlet pass, intermediate pass and the outlet pass.
- the outside channel is adapted to receive the fluid from and distribute the fluid to the inlet pass, intermediate pass and the outlet pass at places which promote the flow through and from specific tubes within the pass, while hindering the flow through and from the remaining ones.
- the outside channel is fluidly connected to the second manifold such that there is a first opening at the level of the inlet pass, a second opening at the level of the intermediate pass, and a third opening at the level of the outlet pass to enable flow between the passes and the manifold.
- each of the openings is located in the lower section of respective pass.
- the heat exchanger further comprises a tubular body connected fluidically to the first manifold so that it can receive the fluid from and distribute the fluid to the inlet pass, intermediate pass and the outlet pass, wherein the tubular body comprises the controlling means.
- the controlling means comprise a valve assembly, the valve assembly comprising two baffles connected to each other and adapted to cooperate with the tubular body so that in the first state they block fluid flow between the inlet pass and the intermediate pass, and in the second state they block fluid flow between the intermediate pass and the outlet pass.
- controlling means are adapted to switch between the first state and the second state based on temperature of the core and/or environment of the heat exchanger.
- Another object of the invention is an air conditioning circuit comprising a heat exchanger as described above.
- Figs. 1 and 2 present heat exchanger according to the invention, wherein Fig. 1 shows the heat exchanger in heat pump mode, while Fig. 2 shows the heat exchanger in air conditioning mode.
- a heat exchanger 1 comprises a first manifold 2 and a second manifold 3 connected by a bundle of tubes 4.
- the heat exchanger is configured to provide an inlet pass 5, an outlet pass 6 and an intermediate pass 7 for a heat exchange fluid, the intermediate pass 7 being located between the inlet pass 5 and the outlet pass 6.
- the tubes 4 within the bundle are spaced with respect to each other to enable heat exchange with a second fluid, for example air, travelling through the spaces between the tubes. Said spaces may comprise fins for facilitating the heat exchange.
- the heat exchanger 1 further comprises an inlet port 8 associated with the inlet pass 5 and an outlet 9 port associated with an outlet pass 6, wherein both are located on the first manifold 2.
- the heat exchanger 1 further comprises controlling means 50 adapted to switch between a first state, in which co-flow of the heat exchange fluid in the outlet pass 6 and the intermediate pass 7 with counterflow in the inlet pass 5 is enabled, and a second state in which co-flow of the heat exchange fluid in the inlet pass 5 and the intermediate pass 7 with counterflow in the outlet pass 5 is enabled. This may be done by selectively blocking the flow between the passes by the controlling means 50.
- the controlling means 50 are adapted to receive the fluid from and distribute the fluid to the inlet pass 5, intermediate pass 7 and the outlet pass 6.
- One example of implementation of controlling means adapted for switching between the first state and the second state may be integrating them into or with a tubular body 10 connected fluidically to the first manifold 2 so that it can receive the fluid from and distribute the fluid to the inlet pass 5, intermediate pass 7 and outlet pass 6.
- the controlling means 50 may comprise a valve assembly with two baffles 41, 42 connected to each other (for example by a rod 43), and adapted to cooperate with the tubular body 10 so that in the first state they block fluid flow between the inlet pass 5 and the intermediate pass 7, and in the second state they block fluid flow between the intermediate pass 7 and the outlet pass 6.
- the switching between the first and second states may be controlled automatically or manually. Other ways of effecting the blocking and enabling the flow as explained above are also possible as long as they allow to execute reliably the functioning of the heat exchanger.
- the flow between the inlet pass 5, the intermediate pass 7 and the outlet pass 6 may be blocked within the second manifold 3.
- the heat exchanger then further may comprise an outside channel 11, the outside channel 11 being adapted to receive the fluid from and distribute the fluid to the inlet pass 5, intermediate pass 7 and the outlet pass 6.
- the outside channel 11 then is fluidly connected to the second manifold 3 such that there is a first opening 31 at the level of the inlet pass 5, a second opening 32 at the level of the intermediate pass 7, and a third opening 33 at the level of the outlet pass 6.
- the outside channel 11 is adapted to receive the fluid from and distribute the fluid to the inlet pass 5, intermediate pass 7 and the outlet pass 6 at places which promote the flow through and from specific tubes within the pass, while hindering the flow through and from the remaining ones of said pass.
- each of the openings 31, 32, 33 is located in the lower section of respective pass 5, 7, 6.
- the controlling means 50 are set to the first state.
- the refrigerant enters the heat exchanger through the inlet port 8 and then travels through the inlet pass 5.
- the fluid then is turned and flows in the intermediate pass 7 as well as the outlet pass 6, as allowed by the controlling means 50, both in a direction opposite to the direction within the inlet pass 5.
- the fluid then may exit the heat exchanger through the outlet port 9.
- the controlling means are set in the second state.
- the refrigerant enters the heat exchanger through the inlet port 8 and then travels through the inlet pass 5, as well as the intermediate pass 7 in the same direction, as allowed by the controlling means 50.
- the fluid then is turned and flows in the outlet pass 6 in a direction opposite to the direction within the inlet and intermediate passes 5, 7.
- the fluid then may exit the heat exchanger through the outlet port 9.
- the switching between the first state and the second state allows to achieve optimal performance, connected to the amount of tubes within passes, without reversing the flow within the same heat exchanger.
- the controlling means 50 can be driven based on temperature, e.g. thermostatic valve or pressure e.g. pressure valve.
- Thermostatic valve can be beneficial due to fact that with system in a switch of state, it will adjust its position according to more probable position. For example, it will switch to AC mode in summer when temperature of the environment and/or core will be high, or HP mode when temperature of the environment and/or the core will be low, for example in winter.
- valves e.g. rotating valve, actuators e.g. driven by various factors, including solenoid, core, repartition of tubes, number of passes etc.
- actuators e.g. driven by various factors, including solenoid, core, repartition of tubes, number of passes etc.
- inlet, intermediate and outlet passes may be neighbored by further passes, and necessarily be directly connected to inlet and/or outlet ports. Nevertheless, the general concept can still be applicable.
