Description

Technical Field

[0001] This utility model relates to the field of seawater constant temperature regulation technology, and in particular to a test bench simulation seawater temperature water system. Background Technology

[0002] The benchtop seawater constant temperature system is primarily used for laboratory testing of marine engines, ensuring that equipment or samples operate at a constant water temperature, with a temperature adjustment range of 18℃ to 60℃. Through precise temperature control and regulation, this system adapts to experimental or testing environments requiring stable water temperatures. The system's working principle consists of several key components. First, the user sets the target temperature through the control system, and the system adjusts the water temperature according to the set value. Temperature sensors monitor seawater temperature changes in real time and feed the data back to the benchtop control system for precise adjustment.

[0003] In terms of temperature regulation, the system can automatically activate the corresponding heating or cooling devices according to different water temperatures. When the water temperature is lower than the set value, the heat generated by the engine heats the seawater to raise the water temperature; when the water temperature is higher than the set value, the cooling device is activated to lower the water temperature with ambient temperature cooling water or chilled water, thereby ensuring that the water temperature is always maintained within the set range.

[0004] Existing heating devices typically employ traditional heat exchangers. These exchangers contain heat exchange coils, through which a heat transfer medium is introduced to exchange heat with flowing seawater, thus raising the water temperature. However, this method has several significant drawbacks. First, the heat exchange efficiency is low, primarily because the heat exchange process between the heat transfer medium and seawater is limited by the heat transfer area and flow pattern of the coils, resulting in insufficient heat transfer. Second, due to uneven seawater flow within the heat exchanger and design issues with the heat exchange coil layout, the temperature rise is not uniform, easily creating temperature differences within the water body. This makes it impossible to ensure a consistent seawater temperature throughout the system, thus affecting testing accuracy and equipment stability. Utility Model Content

[0005] The purpose of this invention is to overcome the limitations of existing technologies where heating devices typically employ traditional heat exchangers. These devices use heat exchangers with heat exchange coils to introduce a heat transfer medium into the coils for heat exchange with flowing seawater, thereby raising the water temperature. However, this heat exchange method has several significant drawbacks. First, the heat exchange efficiency is low, primarily because the heat exchange process between the heat transfer medium and seawater is limited by the heat transfer area and flow pattern of the coils, resulting in insufficient heat transfer. Second, due to uneven seawater flow within the heat exchanger and design issues with the heat exchange coil layout, the uniformity of the water temperature increase is poor, easily leading to temperature differences within the water body. This makes it impossible to ensure a consistent seawater temperature throughout the system, thus affecting testing accuracy and equipment stability. A benchtop system for simulating seawater temperature is provided. A partition is installed inside the heat exchanger, dividing its interior into two independent chambers: a first chamber and a second chamber. Several fins are arranged on the heat exchange tubes to increase the heat exchange area and improve heat exchange efficiency. The fins further divide the first and second chambers into several independent sub-spaces, which, together with staggered circular through-holes, form channels for seawater flow. This structural design, combined with the partition, maximizes the heat exchange path and improves the heat exchange effect. Furthermore, the staggered circular through-holes can impact and disperse the seawater flowing between adjacent sub-spaces, reducing its flow velocity and improving the uniformity of heating, further optimizing the overall heating process.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The engine inlet water pipe and the engine return water pipe are interconnected. A heat exchanger and a heat exchanger are connected in series on the engine return water pipe. The heat exchanger and the heat exchanger exchange heat the seawater flowing in the engine return water pipe to maintain a constant water temperature. The open auxiliary water tank is connected to the engine inlet water pipe through a conduit, and a control valve is installed on the conduit.

[0008] Preferably, the heat exchanger consists of an outer frame and two sealing covers, the two sealing covers closing the openings on both sides of the outer frame to form a sealed structure;

[0009] A partition is provided at the center of the interior of the outer frame, which divides the interior of the outer frame into two independent chambers: a first chamber and a second chamber.

The fins and heat exchange tubes are arranged perpendicular to each other, and the heat exchange tubes on both sides of the partition are interconnected via connecting pipes. The fins divide the first and second chambers into several independent sub-spaces, and staggered circular through-holes form seawater flow channels. This structural design, combined with the partition, maximizes the heat exchange path and improves the heat exchange effect.

[0012] Preferably, the top of the outer wall of the heat exchanger is provided with an inlet pipe and an outlet pipe, which are connected in series on the engine return water pipe. The inlet pipe is connected to the first chamber, and the outlet pipe is connected to the second chamber.

[0013] The multiple fins divide the first chamber and the second chamber into multiple independent and enclosed subspaces. The fins are provided with circular through holes, so that the subspaces are interconnected to form heat exchange channels for seawater flow.

[0014] Preferably, a circular hole is provided through the bottom end of the side wall of the partition, through which the first chamber and the second chamber are connected to each other;

[0015] The fins have three circular through holes, with equal spacing between two adjacent circular through holes. The circular through holes on adjacent fins are staggered. Through the staggered circular through holes, the seawater flowing between adjacent subspaces can be impacted and dispersed, reducing its flow velocity, improving the uniformity of heating, and further optimizing the effect of the entire heating process.

[0016] Preferably, sealing strips are adhered to both sides of the fin in the first and second chambers, and a sealing gasket is adhered to the back of the sealing cover.

[0017] Sealing strips and gaskets are used to ensure the airtightness of the subspace formed between two adjacent fins, so that seawater can only flow through the circular through-holes on the fins and the heat exchange channels formed by the subspace.

[0018] Preferably, the bottom of the outer wall of the heat exchanger is provided with a refrigerant inlet pipe and a refrigerant outlet pipe;

[0019] Both the heat transfer medium inlet pipe and the refrigerant inlet pipe are equipped with control valves. These control valves are used to control the flow rate of the heat transfer medium inlet pipe and thus change its heat exchange efficiency.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This test bench simulates seawater temperature and water system by dividing the heat exchanger into two independent chambers, a first chamber and a second chamber, using a baffle plate. Several fins are arranged on the heat exchange tubes to increase the heat exchange area and improve efficiency. The fins also divide the first and second chambers into several independent sub-spaces, with staggered circular through-holes forming channels for seawater flow.

These devices involve setting up heat exchangers and arranging heat exchange coils within them to introduce a heat transfer medium that exchanges heat with flowing seawater, thereby raising the water temperature. However, this heat exchange method has several significant drawbacks. First, the heat exchange efficiency is low, primarily because the heat exchange process between the heat transfer medium and seawater is limited by the heat transfer area and flow pattern of the coils, resulting in insufficient heat transfer. Second, due to uneven seawater flow within the heat exchanger and design issues with the heat exchange coil layout, the uniformity of the temperature increase is poor, easily leading to temperature differences within the water body. This makes it impossible to ensure a consistent seawater temperature throughout the system, thus affecting testing accuracy and equipment stability. A benchtop system for simulating seawater temperature is provided. A partition is installed inside the heat exchanger, dividing its interior into two independent chambers: a first chamber and a second chamber. Several fins are arranged on the heat exchange tubes to increase the heat exchange area and improve heat exchange efficiency. The fins further divide the first and second chambers into several independent sub-spaces, which, together with staggered circular through-holes, form channels for seawater flow. This structural design, combined with the partition, maximizes the heat exchange path and improves the heat exchange effect. Furthermore, the staggered circular through-holes can impact and disperse the seawater flowing between adjacent sub-spaces, reducing its flow velocity and improving the uniformity of heating, further optimizing the overall heating process.
