Definitions
- the present invention relates to a heat exchanger, in particular arranged for placement in a compartment of a vessel, which is provided with heat exchanging elements and a base with an inlet and outlet which are connected to the heat exchanging elements for transporting a liquid from the inlet through the heat exchanging elements to the outlet for exchanging heat between said liquid and outboard water, wherein the heat exchanger further comprises an anti-fouling system arranged to reduce fouling of the heat exchanging elements.
- Heat exchanger for a marine vessel for instance in the form of box coolers, are known. Liquid, for instance cooling liquid from the engine of the vessel, is fed from the inlet of the heat exchanger through the exchanging elements, for instance in the form of a bundle of tubes, to the outlet.
- the heat exchanging elements are in contact with low temperature sea water in the compartment such that the liquid is cooled.
- a problem associated with these type of heat exchangers is fouling of in particular the heat exchanging elements. This bio-fouling is due to the growth of organisms such as algae, mussels, clams, seaweed and the like on said heat exchanging elements which reduces the capacity of the heat exchanger.
- the heat exchanger as referred to in the preamble is characterized in that the anti-fouling system comprises at least one vibrating device in contact with the heat exchanger and arranged for vibrating the heat exchanging elements to reduce fouling thereof. Tests have concluded that by vibrating the heat exchanging elements, for instance in the form of a bundle of tubes, fouling is reduced or even prevented.
- the vibrating devices are therefore arranged to induce such a vibrating motion to the heat exchanging elements that this vibrating motion alone significantly reduces or even prevents fouling of these heat exchanging elements.
- the anti-fouling system is according to a further preferred embodiment arranged to reduce fouling with at least 50% compared to fouling in a non-treated heat exchanger. It is however preferred if the anti-fouling system is arranged to vibrate the heat exchanging elements such that due to the vibrating, i.e. the oscillating movement of the heat exchanging elements, fouling is substantially prevented.
- the vibrating devices are in direct contact with the heat exchanging elements or base, which is in direct connection to the heat exchanging elements, to conduct the vibrating movement from the vibrating device to the heat exchanging elements. More preferably, the vibrating device is arranged for transferring at least the majority of the kinetic energy of the vibrating motion of said vibrating device to said heat exchanging elements and/or base. This results in an energy efficient anti-fouling system.
- the anti-fouling system comprises a controller for controlling the vibrating device or more preferably a plurality of vibrating devices.
- the controller may hereto be provided with an oscillating power source for providing a control signal for controlling the vibrating device to vibrate with a predetermined frequency.
- the control signal may be an alternating current having the predetermined frequency.
- the vibrating motion of the vibrating device is transferred to the heat exchanging elements, such that also the heat exchanging elements vibrate with a frequency which may be different from the vibrating frequency of the vibrating devices.
- the anti-fouling system preferably comprises a plurality of vibrating devices for vibrating the heat exchanging elements to improve the anti-fouling action, in particular for a larger heat exchanger.
- the system comprises a plurality of vibrating devices and a controller arranged for controlling the vibrating devices to vibrate the heat exchanger in phase.
- Each of the vibrating devices hereby vibrates with the same frequency such that the heat exchanger, for instance the base, oscillates in phase.
- the energy required for efficiently vibrating the heat exchanging elements to reduce fouling thereof is hereby reduced.
- the anti-fouling system is arranged to vibrate the heat exchanging elements with a frequency in the range of 20 to 100 kHz.
- a controller may be arranged to control the vibrating device such that the heat exchanger is vibrated with a frequency in the above mentioned range. The vibrating device may therefore vibrate with the same frequency in the range of 20 to 100 kHz.
- the anti-fouling system is arranged to vibrate the heat exchanging elements with an amplitude of 1 to 10 micrometer.
- the vibrating devices preferably oscillates with an amplitude in the same range, wherein the oscillating movement of vibrating device preferably substantially corresponds to the oscillating movement of the heat exchanging elements.
- the vibrating device comprises an ultrasonic transducer. These transducer are arranged to produce a high frequency vibration.
- the transducers are not used for creating ultrasound but to impart a vibrating motion to the heat exchanging elements.
- the vibrating device comprises a piezoelectric transducer.
- Such transducers are widely available and typically comprise two vibrating elements sandwiching a piezoelectric element. By supplying an alternating current to electrodes of the piezoelectric element, the piezoelectric element contracts and expands and thereby moves the vibrating elements. At least one of these vibrating elements is preferably in contact with the base and/or the heat exchanging elements.
- this heat exchanger may be provided with at least one vibrating device for vibrating the heat exchanging elements in the form of the plates.
- the vibrating device may for instance be provided on a base plate, which preferably also holds the in- and outlets.
- the heat exchanger is however arranged for placement in a compartment of a vessel, wherein the heat exchanging elements are arranged for exchanging heat between said liquid and outboard water in the compartment.
- the base comprises a wet section arranged to extend in the compartment and from which the heat exchanging elements protrude and a dry section provided with the inlet and the outlet and arranged to extend outside of the compartment.
- the base is preferably plate shaped and is arranged to be accommodated in a correspondingly shaped opening of the compartment.
- the heat exchanging elements typically protrude from a first wet side of the base arranged to be in contact with the water in the compartment and the inlet an outlet are provided on an opposite dry side arranged to extend outside the compartment.
- the base may be provided with connecting holes provided near the edge of the base.
- the vibrating device is provided on the dry section of the base and preferably in direct contact therewith.
- the vibrating device may for instance be provided on the dry side also provided with the inlet and outlet or on a circumferential surface of the base, i.e. a surface extending perpendicularly the dry and wet sides of base. Due to the fact that the vibrating device is on the dry section, and therefore on the outside of the compartment in use, the vibrating device is not exposed to outboard water. This increases the lifetime of the vibrating device and requires less maintenance of the anti- fouling system compared to sea water exposed anti-fouling systems.
- the anti-fouling system further comprises a sensor for sensing the vibrating amplitude and/or frequency of the heat exchanging elements and which is connected to a controller, wherein the controller is arranged to control the vibrating device in dependency of the sensed vibrating amplitude and/or frequency by the sensor for vibrating the heat exchanging elements with a predetermined frequency and/or amplitude.
- the controller comprises a proportional-integral-derivative controller (PID controller) for driving the vibrating devices using the sensed vibration as feedback. More preferably, the predetermined
- the frequency/amplitude corresponds to the range of amplitudes and frequencies as mentioned above.
- the frequency and/or amplitude of the oscillating movement of the heat exchanging elements may be measured by measuring the oscillating movement of the base.
- the heat exchanger comprises a plurality of transducers as vibrating devices, wherein at least one of the vibrating devices is arranged as the sensor for sensing the vibrating amplitude and/or frequency.
- transducers can operate as actuators and sensors, one of the vibrating devices is used as sensor. A separate part for sensing the amplitude and/or frequency is then not necessary.
- the senor comprises an ultrasonic transducer, even more preferably a piezoelectric transducer.
- the sensor is provided on the dry section of the base as described above for the vibrating device as such. It is moreover preferred that the sensing device is in direct contact with the base to improve the quality of the

- a system further comprises a sensor as described above, more preferably in the form of a vibrating transducer.
- the invention furthermore relates to a method for reducing fouling of a heat exchanger for a vessel, preferably arranged in a compartment of said vessel, which is provided with heat exchanging elements and a base with an inlet and outlet which are connected to the heat exchanging elements for transporting a liquid from the inlet through the heat exchanging elements to the outlet for exchanging heat between said liquid and outboard water, preferably in the compartment, wherein the method comprises the step of vibrating the heat exchanging elements to reduce fouling thereof.
- the step of vibrating preferably comprises vibrating the heat exchanging elements with a frequency in the range of 20 to 100 kHz. It is further preferred if the step of vibrating comprises vibrating the heat exchanging elements with an amplitude of 1 to 10 micrometer.
- the present invention is further illustrated by the following Figures, which show a preferred embodiment of the system according to the invention, and are not intended to limit the scope of the invention in any way, wherein:

- the heat exchanger 2 comprises heat exchanging elements 4 in the form of a bundle of tubes 41 bent in U-shape, see figure 3.
- the bundle of tubes 41 extends and is in contact with sea water W in the compartment 101.
- the compartment 101 is partially enclosed by the hull 102 of the vessel 100.
- the compartment 101 is further provided with side walls 106, a top wall 105 and end walls (not shown). Sea water W is allowed to enter through openings 103 and exits the compartment 101, after passing through the bundle of tubes 41, through openings 104.
- the heat exchanger 2 is provided with a base plate 3 from which the tubes 41 of the tube bundle protrude.
- the tubes 41 extend from an inlet side 42 in an U-shape to an outlet side 43.
- the inlets 42 and outlets 43 of the tubes 41 are connected to respective inlet and outlet manifolds 51 and 61, to which an inlet 5, respectively outlet 6 are connected.
- the base plate 3 of the heat exchanger 2 is connected on a flange 105 a surrounding an opening in top wall 105 of the compartment 101.
- the edges of the base plate 3 are thereto provided with connecting holes 34, see figure 4.
- a part 31 of the lower side of the base plate 3 is contact with sea water W, and is therefore referred to as the wet section 3a, whereas the top side 32 and edge surface 33 are outside the compartment and therefore form a dry section 3b of the base 3.
