Description

Title: A heat exchanger arranged for exchanging heat between a first medium and a second medium and a method of exchanging heat between a first medium and a second medium using the heat exchanger
Description:
According to a first aspect, the present disclosure relates to a heat exchanger arranged for exchanging heat between a first medium and a second medium.
According to a second aspect, the present disclosure relates to a method of exchanging heat between a first medium and a second medium using the heat exchanger according to the first aspect of the present disclosure.
The heat exchanger according to the present disclosure is arranged for exchanging heat between a first medium and a second medium, wherein the heat exchanger comprises a first flow arrangement comprising first flow sections, a second flow arrangement comprising second flow sections, wherein the first flow sections and the second flow sections are provided alternated with respect to each other and extend in a radial direction away from a central axis.
Providing the first flow sections and the second flow sections alternate with respect to each other and extending in a radial direction is beneficial for allowing for a relative efficient heat transfer while allowing to realise a relative compact heat exchanger.
Preferably, the first flow sections and the second flow sections completely surround the central axis. This is beneficial for realising an attractive form factor. More specifically, by completely surrounding the central axis a relative large heat exchange capacity may be realised while maintaining a relative compact heat exchanger.
It is beneficial if one of the first flow sections and the second flow sections is provided with a dividing wall element extending in a tangential direction relative to the central axis and arranged for dividing the corresponding first flow sections and the second flow sections in at least two flow sub-sections. This is beneficial for allowing to maintain a laminar flow of the first medium and/or second medium over a relative broad range of flow parameters such as flow rate.
Preferably, the dividing wall element extends along the one of the first flow sections and the second flow sections between an inlet opening and an outlet opening of the one of the first flow sections and the second flow sections. This is beneficial for allowing to maintain a laminar flow of the first medium and/or second medium over a relative broad range of flow parameters such as flow rate.
In an embodiment, one of the first flow sections and the second flow sections is provided with a plurality of the dividing wall elements and a distance between neighbouring dividing wall elements of the plurality of dividing wall elements is different. This is beneficial for allowing to maintain a laminar flow of the first medium and/or second medium over a relative broad range of flow parameters such as flow rate.
In a further embodiment, the distance between neighbouring dividing wall elements is equal to or larger than a thickness of the dividing wall elements in the radial direction. This is beneficial for allowing to maintain a laminar flow of the first medium and/or second medium over a relative broad range of flow parameters such as flow rate.
In another embodiment, a ratio of a wettable perimeter of a flow sub-section and a flow cross-section of the flow sub-section is in the range of 0.5 to 2 time a ratio of a wettable perimeter of the corresponding flow section and the flow cross-section of the corresponding flow section.
In yet another embodiment, the heat exchanger comprises a housing arrangement arranged for housing the first flow arrangement and the second flow arrangement.
In a practical situation, the heat exchanger further comprises a third flow arrangement, wherein the third flow arrangement is provided at an outer perimeter of the first flow sections and the second flow sections. This in particular beneficial when, during use, the cooler medium of the first medium and the second medium is flowing through the third flow arrangement for reducing heat loss to the surrounding of the heat exchanger and thereby realising a relative efficient heat exchanger, or in other words, realising a relative low energy loss to the surrounding of the heat exchanger.
Furthermore in a practical situation, the housing arrangement comprises the third flow arrangement. This in particular beneficial when, during use, the cooler medium of the first medium and the second medium is flowing through the third flow arrangement for reducing heat loss, via the housing of the heat exchanger, to the surrounding of the heat exchanger and thereby realising a relative efficient heat exchanger, or in other words, realising a relative low energy loss to the surrounding of the heat exchanger via the housing of the heat exchanger.
It is beneficial if the heat exchanger further comprises: - a first coupling arrangement comprising a first inlet arranged for allowing the first medium to enter the heat exchanger and a first outlet arranged for allowing the second medium to exit the heat exchanger; - a second coupling arrangement comprising a second inlet arranged for allowing the second medium to enter the heat exchanger and a second outlet arranged for allowing the first medium to exit the heat exchanger; wherein the first flow arrangement is coupled for fluid flow with the first inlet and the second outlet and the second flow arrangement is coupled for fluid flow with the second inlet and the first outlet.
Preferably, the first coupling arrangement and the second coupling arrangement are releasably connected to the housing arrangement. This is beneficial for allowing to provide maintenance to the heat exchanger in a practical manner.
In an embodiment, the dividing wall element extends along the one of the first flow sections and the second flow sections between the first coupling arrangement and the second coupling arrangement.
In a further embodiment, the layout of the first coupling arrangement and the second coupling arrangement is identical.
In another embodiment, the third flow arrangement is coupled for fluid flow with the first inlet and the second outlet or with the second inlet and the first outlet.
In yet another embodiment, a joint flow cross-section of the first flow sections is larger than a flow cross-section of the first inlet and/or wherein a joint flow cross- section of the second flow sections is larger than a flow cross-section of the second inlet, preferably wherein the joint flow cross-section of the first flow sections is in the range of four to eight times larger than the flow cross-section of the first inlet and/or wherein the joint flow cross-section of the second flow sections is in the range of four to eight times larger than a flow cross-section of the second inlet, more preferably wherein the joint flow cross-section of the first flow sections is more than eight times larger than the flow cross-section of the first inlet and/or wherein the joint flow cross- section of the second flow sections is more than eight times larger than a flow cross- section of the second inlet. This is beneficial for reducing the velocity of the first medium and/or the second medium thereby increasing an efficiency of the heat exchanger. This is beneficial for allowing to realize a relative low velocity of the first medium and/or the second medium when present in the first flow sections and/or the second flow sections. A relative low velocity is beneficial for realizing a relative large heat transfer between the first medium and the second medium. In addition a relative low velocity is beneficial for allowing to realize a laminar flow of the first medium and/or the second medium when present in the first flow sections and/or the second flow sections.
The present disclosure relies at least partly on the insight that a relative low flow velocity of the first medium and/or the second medium causes a relative long presence of the first medium and/or the second medium inside the heat exchanger which is beneficial for exchanging a relative large amount of the heat between the warmer medium and the colder medium.
In a practical situation a wettable perimeter of a section of the first flow sections 5 and/or the second flow sections is smaller than 2.5 times the flow cross-section of the section of the first flow sections and/or the second flow sections, preferably wherein the section of the first flow sections and/or the second flow sections is in the range of 2.5 to 3.5 times the flow cross-section of the section of the first flow sections and/or the second flow sections.
Furthermore in a practical situation, the heat exchanger comprises an equal number of first flow sections and second flow sections.
It is beneficial if the first coupling arrangement, the second coupling arrangement, the first flow arrangement and/or the second flow arrangement are obtained by additive manufacturing.
Preferably, the heat exchanger comprises a thermoelectric generator arranged for generating electrical energy based on the temperature difference of the first medium and the second medium, preferably wherein the thermoelectric generator is provided between a first flow section of the first flow sections and a second flow section of the second flow sections.
According to a second aspect, the present disclosure relates to a method of exchanging heat between a first medium and a second medium using the heat exchanger according to any one of the preceding claims, the method comprising the steps of: - providing the first medium, via the first inlet, to the heat exchanger; - providing the second medium, via the second inlet, to the heat exchanger; - removing the first medium, via the second outlet, from the heat exchanger;
- removing the second medium, via the first outlet, from the heat exchanger.
Embodiments of the heat exchanger according to the first aspect of the present disclosure as presented previously are also applicable to the method according to the second aspect of the present disclosure, and vice versa.
Effects of the heat exchanger according to the first aspect of the present disclosure as presented above correspond to or are similar to effects of the method according to the second aspect of the present disclosure
In a practical situation, the first medium and the second medium are liquids.
It is beneficial if the cooler one of the first medium and the second medium is provided to the third flow arrangement.
Preferably, one of the first medium and the second medium is steam condensate.
In an embodiment, at least one of the first medium and the second medium is maintained in a laminar flow.
In a further embodiment, the flow speed of the first medium and/or the second medium in the first flow sections and/or the second flow sections is lower than 0.5 m/s.
The device is configured in a modular design, comprising multiple interchangeable and/or detachable components, each configured to perform distinct functions, which can be assembled or reconfigured without altering the overall structural integrity or functional capability of the device. This modular configuration allows for easy customization, maintenance, and scalability of the device to meet various operational requirements.
