Description

Technical Field

[0001] This utility model relates to the field of ship engine room cooling technology, and in particular to a louver with a seawater loop. Background Technology

[0002] Considering that in summer operating conditions (assuming 35℃), the temperature inside the engine room of a ship can typically reach above 40℃ due to the large amount of heat dissipation. Under such temperatures, a large number of equipment and electrical instruments inside the engine room will operate in a relatively unfavorable environment, and the crew will often be drenched in sweat during maintenance and inspection. In order to improve this environment, and at a relatively low cost, so that personnel and equipment can be in a more comfortable environment, and since these equipment and instruments are relatively expensive, this improvement in environment can also extend the life of the equipment and instruments. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, this utility model provides a louver with a seawater loop, which cools the incoming air and thus reduces the temperature inside the cabin.

[0004] This utility model embodiment provides a louver with a seawater loop, comprising:

[0005] Ventilation louvers, equipped with an outdoor temperature sensor for detecting outdoor temperature;

[0006] A seawater cooling coil is provided on the side of the ventilation louver inside the engine room, and the seawater cooling coil is equipped with a pressure sensor for detecting the air pressure blown into the engine room through the ventilation louver.

[0007] When the temperature detected by the outdoor temperature sensor is higher than the set temperature value and the pressure value detected by the pressure sensor is greater than the first set pressure value, the seawater delivery device is activated to supply seawater to the seawater cooling coil, so as to cool the air blown in through the ventilation louvers through the seawater cooling coil, thereby achieving cooling of the cabin.

[0008] In some embodiments of this utility model, the seawater conveying device includes:

[0009] A seawater pump is used to draw seawater and is connected to the seawater cooling coil through a seawater supply pipe and a seawater outlet pipe, respectively.

[0013] In some embodiments of this utility model, the louver with seawater loop further includes:

[0014] The control box is connected to the seawater pump, the seawater pipe inlet valve, the seawater pipe outlet valve, the outdoor temperature sensor, and the pressure sensor.

[0015] When the control box receives signals that the temperature detected by the outdoor temperature sensor is higher than the set temperature value and the pressure value detected by the pressure sensor is greater than the set pressure value, it controls the seawater conveying device.

[0016] In some embodiments of this utility model, if the temperature detected by the outdoor temperature sensor is lower than the set temperature value after the seawater conveying device is started, the seawater conveying device is stopped.

[0017] In some embodiments of this utility model, after the seawater conveying device is started, if the pressure value detected by the pressure sensor is lower than the second set pressure value, the seawater conveying device is stopped, wherein the second set pressure value is not greater than the first set pressure value.

[0019] If the pressure value detected by the pressure sensor is lower than the second set pressure value and the duration is longer than the set time value, the seawater conveying device shall be stopped.

[0020] In some embodiments of this utility model, the louver with seawater loop further includes:

[0021] An indoor temperature sensor is used to detect the temperature inside the cabin.

[0022] In some embodiments of this utility model, the seawater cooling coil is specifically disposed on a heat dissipation profile equipped with a finned structure.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Various embodiments and features of this application are described herein with reference to the accompanying drawings.

[0031] It should also be understood that although this application has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this application, which have the features described in the claims and are therefore all within the scope of protection defined herein.

[0032] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0033] Specific embodiments of this application are described below with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to ascertain the true intent based on the user's historical operations, and to avoid unnecessary or redundant details that would obscure this application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in various ways with substantially any suitable detailed structure.

[0034] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0035] This utility model embodiment provides a louver with a seawater loop, such as Figure 1 and Figure 2 As shown, it includes:

[0036] Ventilation louvers 1, which are equipped with an outdoor temperature sensor 2 for detecting the outdoor temperature;

[0037] Seawater cooling coil 3 is located on the side of the ventilation louver 1 inside the engine room, and the seawater cooling coil 3 is equipped with a pressure sensor 4 for detecting the air pressure blown into the engine room through the ventilation louver 1.

[0038] When the temperature detected by the outdoor temperature sensor 2 is higher than the set temperature value and the pressure value detected by the pressure sensor 4 is greater than the first set pressure value, the seawater delivery device is activated to supply seawater to the seawater cooling coil 3, so as to cool the air blown in through the ventilation louvers 1 through the seawater cooling coil 3, thereby achieving cooling of the cabin.

[0039] In the above technical solution, since the engine room ventilation louvers 1, the engine room ventilation fan and the corresponding seawater pump 5 are usually existing components in the ship equipment, the above device is an improvement on this basis, only adding seawater cooling coil 3, pressure sensor 4, temperature sensor, electric valve and control box 8 behind the ventilation louvers 1.

[0040] In this embodiment, the seawater conveying device includes:

[0041] Seawater pump 5 is used to draw seawater and is connected to the seawater cooling coil 3 through a seawater supply pipe and a seawater outlet pipe, respectively.

[0042] Seawater pipe inlet valve 6 is installed on the seawater supply pipe;

[0043] Seawater pipe outlet valve 7 is installed on the seawater pipe outlet pipe;

[0044] When the seawater conveying device is started, the seawater pump 5, the seawater pipe inlet valve 6, and the seawater pipe outlet valve 7 are all in the start state. The seawater pipe inlet valve 6 and the seawater pipe outlet valve 7 are both solenoid valves.

[0045] The louver with seawater loop also includes a control box 8, which is connected to the seawater pump 5, the seawater pipe inlet valve 6, the seawater pipe outlet valve 7, the outdoor temperature sensor 2, and the pressure sensor 4.

[0046] When the control box 8 receives a signal that the temperature detected by the outdoor temperature sensor 2 is higher than the set temperature value and the pressure value detected by the pressure sensor 4 is greater than the set pressure value, it controls the pneumatic operation of the seawater conveying device.

[0047] Specifically, as an example, when the temperature sensor detects that the outdoor temperature, i.e. the intake air temperature, exceeds the set temperature value (e.g., 30°C), and the pressure sensor 4 detects that it has reached or exceeded the first set pressure value (under normal circumstances, the cabin ventilation fan will run all year round), the electric valve will be opened (the seawater pipe inlet valve 6 and the seawater pipe outlet valve will be opened) to deliver seawater to the seawater cooling coil 3, thereby reducing the intake air temperature and thus changing the cabin ambient temperature.

[0048] In some embodiments of this invention, after the seawater conveying device is started, if the temperature detected by the outdoor temperature sensor 2 is lower than the set temperature value, the seawater conveying device is stopped. That is, when the inlet air temperature is detected to be lower than the set temperature value (personnel set value), the electric valve is automatically shut off, and the inlet air enters the cabin at the normal outdoor temperature.

[0049] In another embodiment of this utility model, after the seawater conveying device is started, if the pressure value detected by the pressure sensor 4 is lower than the second set pressure value, the seawater conveying device is stopped. The second set pressure value is not greater than the first set pressure value, and the second set pressure value can be zero. That is, when the pressure sensor 4 detects no pressure, the electric valve is automatically shut off, and air enters the cabin at the normal outdoor temperature.

[0050] Furthermore, if the pressure value detected by the pressure sensor 4 is lower than the second preset pressure value, the seawater conveying device is stopped, specifically including:

[0051] If the pressure value detected by the pressure sensor 4 is lower than the second set pressure value and the duration is longer than the set time value, then the seawater conveying device shall be stopped.

[0052] In some embodiments of this utility model, the louver with seawater loop further includes:

[0053] Indoor temperature sensor 9 is used to detect the temperature inside the cabin.

[0054] The seawater cooling coil 3 is specifically mounted on a heat dissipation profile equipped with a finned structure, thereby increasing the heat exchange area and efficiency between the seawater cooling coil 3 and the incoming air through the heat dissipation profile.

[0055] As can be seen from the above technical solution, the beneficial effects of the louver with seawater loop provided by the above embodiment of the present invention are: the system investment is low, it is easy to implement, and the engine room ventilation temperature is reduced, which effectively improves the internal environment of the engine room, extends the life of equipment and instruments, and allows the crew to work in a more comfortable environment.

[0056] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
