Description

Technical Field

[0001] This utility model relates to a heat sink structure, and in particular to a multi-section heat exchange heat sink with a door liquid supply pipe inside the cabin. Background Technology

[0002] There are two basic types of existing hatch door heat sink liquid supply pipes. One type is located outside the hatch heat sink and connects to the hatch heat sink to provide circulating fluid. Figure 1 As shown, this method requires disconnecting the hatch supply pipe from the hatch when opening it. Repeated disassembly and reassembly can lead to unreliable connections and leaks, and it is also time-consuming and inefficient. Another method involves placing the hatch supply pipe inside the thermal sink of the hull, such as... Figure 2 As shown, this avoids the problem of disassembly when opening the hatch, but the internal hatch liquid supply pipe will occupy the internal space of the heat sink of the hull, reduce the space utilization rate, and increase the cost.

[0003] In addition, for longer heat sinks, the length of the corresponding liquid supply pipe will also increase accordingly. During actual heat exchange, as the length increases, the temperature of the medium in the liquid supply pipe will change continuously, resulting in a large difference in heat exchange effect before and after the heat sink, leading to uneven temperature before and after the heat sink and affecting the test results. Summary of the Invention

[0004] This invention addresses the technical problems of existing heat sinks where the liquid supply pipe needs to be disassembled when the hatch is opened if it is external, and occupies the space of the heat sink when it is internal, and the heat exchange is uneven for long heat sinks. The invention provides a multi-segment heat sink with the liquid supply pipe inside the heat sink that does not occupy its internal space, does not require disassembly when the hatch is opened, and ensures uniform heat exchange even for long heat sinks.

[0005] Therefore, the technical solution of this utility model is a multi-section heat exchange heat sink with a door liquid supply pipe inside the cabin, including a door heat sink, a cabin heat sink, a door liquid supply pipe, and a cabin liquid supply pipe. The door liquid supply pipe is located in the annular space formed by the cabin heat sink and the heat sink frame. One end of the door liquid supply pipe is connected to an external circulating medium storage tank, and the other end is connected to a main pipe on the door heat sink. The main pipe on the door heat sink includes an arc-shaped liquid inlet pipe and an arc-shaped liquid outlet pipe. The arc-shaped liquid inlet pipe is located below the door heat sink, and the arc-shaped liquid outlet pipe is located above the door heat sink. Several door circulating liquid branch pipes are provided between the arc-shaped liquid outlet pipe and the arc-shaped liquid inlet pipe. The diameter of the arc-shaped liquid outlet pipe and the arc-shaped liquid inlet pipe is larger than the diameter of the door circulating liquid branch pipes. The pipe at the connection between the door liquid supply pipe and the door heat sink is a flexible hose.

[0006] Preferably, the exposed portion of the liquid supply pipeline in the hatch is wrapped with a radiation shielding layer to reduce heat exchange between the internal medium and the external environment.

[0007] A multi-section heat exchange heat sink with a liquid supply pipe inside the cabin body. The liquid supply pipeline includes a main liquid inlet pipe and a main liquid outlet pipe. The ends of the main liquid inlet pipe and the main liquid outlet pipe that extend outside the heat sink are respectively connected to an external circulating medium storage tank. The heat sink is provided with several annular heat exchange branch pipes inside the cabin body, which connect the main liquid inlet pipe and the main liquid outlet pipe.

[0008] The main liquid inlet pipe of the cabin includes a first main liquid inlet pipe and a second main liquid inlet pipe. An auxiliary liquid inlet pipe is connected to the second main liquid inlet pipe. One end of the auxiliary liquid inlet pipe and the first main liquid inlet pipe extends outside the heat sink of the cabin and is connected to an external circulating medium storage tank. An insulation layer is provided on the outside of the auxiliary liquid inlet pipe.

[0009] Preferably, the liquid outlet main pipe of the chamber includes a first liquid outlet main pipe and a second liquid outlet main pipe. The first liquid outlet main pipe and the first liquid inlet main pipe are connected by an annular heat exchange branch pipe, and the second liquid outlet main pipe and the second liquid inlet main pipe are connected by an annular heat exchange branch pipe.

[0010] Preferably, the heat sink of the chamber is a multi-section cylindrical structure, and each adjacent cylindrical section is fixedly connected by fasteners.

[0011] The beneficial effects of this utility model are:

[0012] (1) This application sets the liquid supply pipeline of the hatch heat sink in the annular space formed by the heat sink and the heat sink frame, which does not occupy the internal test space, improves the space utilization rate, and since the connection with the hatch heat sink is made of a hose, the liquid supply pipeline does not need to be disassembled when opening the door, which reduces the workload and eliminates the risk of leakage caused by repeated disassembly, thus extending the service life.

[0013] (2) By dividing the main liquid inlet pipe of the chamber into the first liquid inlet pipe and the second liquid inlet pipe, connecting the auxiliary liquid inlet pipe to the second liquid inlet pipe, and setting the insulation layer on the auxiliary liquid inlet pipe, the circulating medium can directly enter the second liquid inlet pipe through the auxiliary liquid inlet pipe, which can avoid the problem of poor heat exchange effect after the circulating medium travels a long distance to reach the back of the heat sink of the chamber, and keep the front and rear temperatures of the heat sink of the chamber consistent.

[0014] (3) The liquid supply pipeline of the hatch is wrapped with a radiation shielding layer on the pipeline outside the heat sink, which can reduce the heat exchange between the medium inside the pipe and the outside, and ensure the heat exchange effect inside the tank; the liquid supply pipeline of the hatch is located inside the heat sink of the tank, which will generate heat exchange with the inside of the tank during the medium circulation process, which can improve the heat exchange efficiency inside the tank.

[0015] (4) The diameters of both the arc-shaped liquid outlet main pipe and the arc-shaped liquid inlet main pipe are larger than the diameter of the door circulating liquid branch pipe, which can ensure that there is sufficient pressure in the circulating liquid branch pipe to provide sufficient circulation power for the medium.

[0016] (5) The heat sink of the cabin is made into a multi-section structure. When the heat sink is long, it can avoid deformation in the middle. Fasteners are used for connection, which makes operation convenient.

[0017] (6) The first liquid inlet pipe and the second liquid inlet pipe can be connected to a liquid outlet pipe or to different liquid outlet pipes, depending on the specific working conditions. Attached Figure Description

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example 1

[0028] like Figure 3-4As shown, a multi-section heat exchange heat sink with a door liquid supply pipe inside the cabin includes a door heat sink 2, a cabin heat sink 1, a door liquid supply pipe 4, and a cabin liquid supply pipe. The door liquid supply pipe 4 is located in the annular space formed by the cabin heat sink 1 and the heat sink frame 3. One end of the door liquid supply pipe 4 is connected to an external circulating medium storage tank, and the other end extends to the outside of the heat sink and is connected to the main pipe of the door heat sink 2.

[0029] like Figure 5 As shown, the main pipe of the hatch heat sink 2 includes an arc-shaped liquid inlet pipe 5 and an arc-shaped liquid outlet pipe 6. The arc-shaped liquid inlet pipe 5 is located below the hatch heat sink 2, and the arc-shaped liquid outlet pipe 6 is located above the hatch heat sink 2. The two are symmetrically arranged and have the same size. Several hatch circulating liquid branch pipes 7 are provided between the arc-shaped liquid outlet pipe 6 and the arc-shaped liquid inlet pipe 5. The heat exchange medium enters the arc-shaped liquid inlet pipe 5 through the liquid inlet pipe of the hatch liquid supply line 4, and then enters the hatch circulating liquid branch pipes 7. After heat exchange, it returns to the external circulating medium storage tank through the liquid outlet pipe of the hatch liquid supply line 4 to enter the next cycle, thereby realizing the temperature control of the hatch heat sink 2.

[0030] The exposed portion of the liquid supply line 4 in the hatch is wrapped with a radiation shielding layer, which can effectively reduce the heat exchange between the internal medium and the outside, thus reducing energy loss. The liquid supply line 4 located inside the heat sink 1 of the cabin will exchange heat with the interior of the cabin during the medium circulation process, which can improve the heat exchange efficiency inside the cabin.

[0031] The external pipes at the connection between the hatch liquid supply line 4 and the hatch heat sink 2 are made of flexible hoses to reduce resistance when opening the door. The diameters of the arc-shaped liquid outlet main pipe 6 and the arc-shaped liquid inlet main pipe 5 are both larger than the diameter of the hatch circulating liquid branch pipe 7, which can ensure sufficient pressure in the hatch circulating liquid branch pipe 7 to provide sufficient circulation power for the medium.

[0032] The liquid supply pipeline of the chamber includes a main liquid inlet pipe and a main liquid outlet pipe. The ends of the main liquid inlet pipe and the main liquid outlet pipe that extend outside the heat sink 1 of the chamber are respectively connected to the external circulating medium storage tank. The heat sink 1 of the chamber is provided with several annular heat exchange branch pipes. The annular heat exchange branch pipes connect the main liquid inlet pipe and the main liquid outlet pipe. More precisely, the annular heat exchange branch pipe consists of two semi-circular heat exchange branch pipes that are connected to the main liquid inlet pipe and the main liquid outlet pipe respectively.

[0033] The circulating medium enters the tank's liquid inlet main pipe from the external circulating medium storage tank, and then enters the annular heat exchange branch pipe from the tank's liquid inlet main pipe. After sufficient heat exchange, it is transported back to the external circulating medium storage tank from the tank's liquid outlet storage tank to enter the next cycle, thereby realizing the temperature control of the tank's heat sink.

[0034] This application improves space utilization by placing the liquid supply pipeline of the heat sink 2 of the hatch in the annular space formed by the heat sink 1 of the cabin and the heat sink frame 3, without occupying the internal test space. Furthermore, since the connection with the heat sink 2 of the hatch is made of a flexible hose, the liquid supply pipeline does not need to be disassembled when opening the door, which reduces the workload and eliminates the risk of leakage caused by repeated disassembly, thus extending the service life.

[0035] Example 2

[0036] Unlike Example 1, as Figure 6 As shown, the main liquid inlet pipe of the cabin is divided into a first liquid inlet pipe 8 and a second liquid inlet pipe 10. The first liquid inlet pipe 8 and the second liquid inlet pipe 10 are connected to the main liquid outlet pipe of the cabin through an annular heat exchange branch pipe. The second liquid inlet pipe 10 is connected to the external circulating medium storage tank outside the cabin heat sink through an auxiliary liquid inlet pipe 9. One end of the first liquid inlet pipe that extends outside the cabin heat sink is connected to the external circulating medium storage tank. The circulating medium enters the first liquid inlet pipe 8 and the auxiliary liquid inlet pipe 9 from the external circulating medium storage tank. The circulating medium in the auxiliary liquid inlet pipe 9 further enters the second liquid inlet pipe 10, which is located at the rear section of the cabin heat sink 1. The circulating medium in the first liquid inlet pipe 8 and the second liquid inlet pipe 10 enters the main liquid outlet pipe of the cabin through the annular heat exchange branch pipe, and then returns to the external circulating medium storage tank to enter the next cycle, completing the heat exchange of the cabin heat sink 1.

[0037] An insulation layer can be installed on the outside of the liquid inlet auxiliary pipe 9 to avoid energy loss during long pipeline transportation, so as to achieve the same temperature at the front and rear ends of the heat sink 1 of the cabin.

[0038] When the heat sink 1 of the cabin is long, the main liquid inlet pipe can be divided into multiple sections according to the specific length and heat exchange requirements, and corresponding auxiliary liquid inlet pipes 9 with insulation layers can be added.

[0039] In this embodiment, the main liquid inlet pipe of the chamber is divided into a first liquid inlet pipe 8 and a second liquid inlet pipe 10. An auxiliary liquid inlet pipe 9 is connected to the second liquid inlet pipe 10. An insulation layer is provided on the auxiliary liquid inlet pipe 9. The circulating medium enters the second liquid inlet pipe 10 directly through the auxiliary liquid inlet pipe 9 without passing through the first liquid inlet pipe 8. This avoids the problem of poor heat exchange effect after the circulating medium travels a long distance to reach the rear of the chamber heat sink 1, and keeps the front and rear temperatures of the chamber heat sink 1 consistent.

[0040] Example 3

[0041] Unlike Embodiment 2, the main liquid outlet pipe of the chamber includes a first liquid outlet pipe 11 and a second liquid outlet pipe 12. The first liquid outlet pipe 11 and the first liquid inlet pipe 8, and the second liquid outlet pipe 12 and the second liquid inlet pipe 10 are connected by annular heat exchange branch pipes. The circulating medium enters the first liquid inlet pipe 8 and the liquid inlet auxiliary pipe 9 from the external circulating medium storage tank. The circulating medium in the liquid inlet auxiliary pipe 9 further enters the second liquid inlet pipe 10 located at the rear section of the heat sink 1 of the chamber. The circulating medium in the first liquid inlet pipe 8 enters the first liquid outlet pipe 11 through the annular heat exchange branch pipe. The circulating medium in the second liquid inlet pipe 10 enters the second liquid outlet pipe 12 through the annular heat exchange branch pipe. The second liquid outlet pipe 12 is connected to the liquid outlet auxiliary pipe 13. The circulating medium returns to the external circulating medium storage tank through the first liquid outlet pipe 11 and the liquid outlet auxiliary pipe 13, respectively, to enter the next cycle and complete the heat exchange of the heat sink 1 of the chamber.

[0042] Combining Embodiments 2 and 3, the first liquid inlet main pipe 8 and the second liquid inlet main pipe 10 can be connected to the same liquid outlet main pipe through an annular heat exchange branch pipe, or they can be connected to different liquid outlet main pipes respectively. The medium returns to the external circulating medium storage tank through different liquid outlet auxiliary pipes, which can be configured according to the specific working conditions.

[0043] Example 4

[0044] Unlike embodiments 1-3, the heat sink 1 of the cabin is a multi-section cylindrical structure, with adjacent sections fixedly connected by fasteners, making operation convenient. The multi-section structure of the heat sink 1 helps prevent deformation in the middle when the heat sink is long.

[0045] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
