Description

Technical Field

[0001] The utility model relates to the field of thermoacoustic heat pumps, in particular to a cooling component and a thermoacoustic heat pump device. Background Technique

[0002] A thermoacoustic heat pump is a device that can convert low-temperature heat energy into high-temperature heat energy, and it has broad application prospects in various fields. Through research, it is found that during the operation of current thermoacoustic heat pump devices, a large amount of heat is formed at the three-way pipe. The specific reasons are as follows:

[0003] First, after the linear motor operates for a long time, heat is generated. Since the linear motor is located on one side of the three-way pipe, the heat will radiate towards the three-way position (as shown by the arrow Va in Figure 1 );

[0004] Second, during the process of heat continuously transferring from the cold end of the regenerator to the hot end through the thermoacoustic effect, the temperature of the hot end continuously rises. Most of the heat will be taken away by the heat exchanger at the hot end, but there is still a part of the heat radiating towards the three-way position (as shown by the arrow Vb in Figure 1 );

[0005] Third, due to the blocking of the acoustic capacitance membrane, the gas is slightly compressed at this position, and then the heat radiating towards the three-way position will be released (as shown by the arrow Vc in Figure 1 ).

[0006] Furthermore, when the thermoacoustic heat pump device needs to be switched to refrigeration, a large amount of heat at the three-way pipe may radiate to the heat exchanger. Correspondingly, due to the radiation of heat, the refrigeration efficiency of the entire thermoacoustic heat pump device will be affected.

[0007] Therefore, a cooling component and a thermoacoustic heat pump device are needed to solve the above problems. Content of the Utility Model

[0008] The purpose of the utility model is to provide a cooling component and a thermoacoustic heat pump device to reduce the temperature at the three-way position of the thermoacoustic heat pump device and improve the refrigeration efficiency and operation stability of the entire thermoacoustic heat pump device.

[0009] To solve the above technical problems, the utility model provides a cooling component, including a housing, at least two flow guiding plates, a water inlet hole, a water outlet hole, and a cooling water circulation system;

[0010] A plurality of the flow guiding plates are fixedly installed inside the housing, and the inner cavity of the housing is divided into a plurality of interconnected chambers along the axial center line direction of the housing;

[0011] When the component to be cooled is placed inside the housing, an S-shaped flow passage is formed around between the plurality of chambers;

[0012] The water inlet hole and the water outlet hole are respectively arranged in the two outermost chambers, and the height of the water inlet hole is higher than that of the water outlet hole.

[0013] The input end and the output end of the cooling water circulation system are respectively connected to the water inlet hole and the water outlet hole.

[0014] Furthermore, both ends of the housing are arranged in a frustum shape, and the outer diameter decreases from inside to outside.

[0015] Furthermore, an opening is provided in the middle of the housing.

[0016] Furthermore, sealing rings are provided at both ends of the housing.

[0017] Furthermore, the housing includes two half-shells that can be fixedly connected;

[0018] A plurality of guide half-pieces are fixedly installed on the inner walls of both half-shells;

[0019] When the two half-shells are fixedly connected, the two guide half-pieces in the same horizontal plane enclose to form the guide plate.

[0020] Furthermore, a gap for the cooling water to pass through is formed between the guide half-piece and the top wall or the bottom wall of the inner cavity of the half-shell.

[0021] Furthermore, two adjacent gaps are arranged in a staggered manner.

[0022] Furthermore, one side of the guide half-piece has an arc surface that matches the outer wall of the component to be cooled.

[0024] The thermoacoustic heat pump body has a tee pipe;

[0025] The housing wraps and is fixedly installed outside the tee pipe.

[0026] Furthermore, the guide plate is engaged with the outer wall of the tee pipe.

[0027] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0035] The temperature reduction component and the thermoacoustic heat pump device of the present invention will be described in more detail below with reference to the schematic diagrams, in which the preferred embodiments of the present invention are shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present invention.

[0036] In the following paragraphs, the present invention will be described more specifically by way of example with reference to the drawings. The advantages and features of the present invention will be clearer according to the following description. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the embodiments of the present invention.

[0037] Embodiment 1

[0038] As Figures 2 to 4As shown in the figure, an embodiment of the present utility model provides a cooling component, which includes a housing 1, at least two flow guide plates 2, a water inlet hole 3, a water outlet hole 4, and a cooling water circulation system (not shown in the figure).

[0039] A plurality of the flow guide plates 2 are fixedly installed inside the housing 1, and the inner cavity of the housing 1 is divided into a plurality of interconnected chambers 5 along the axial center line direction of the housing 1.

[0040] In addition, when the component to be cooled (such as the three-way position of a thermoacoustic heat pump device) is placed inside the housing 1, an S-shaped flow channel is formed around between the plurality of chambers 5 for the circulation of cooling water, so that the cooling water can completely cover the position wrapped by the housing 1 during the circulation process, thereby improving the cooling effect.

[0041] The water inlet hole 3 and the water outlet hole 4 are respectively arranged in two outermost chambers 5, that is, on the outer walls at both ends of the housing 1, to ensure that the cooling water can fully cover the component to be cooled.

[0042] It should be particularly noted that the height of the water inlet hole 3 is higher than that of the water outlet hole 4, so that the cooling water can flow out along the water outlet hole 4 under the action of gravity, reducing the power required for the circulation of the cooling water.

[0043] Wherein, the input end and the output end of the cooling water circulation system are respectively connected to the water inlet hole 3 and the water outlet hole 4 to form a cooling water circulation system, completing the cooling operation of the components inside the housing 1, thereby avoiding the situation that the heat exchanger of the thermoacoustic heat pump device is greatly affected due to the too high temperature at the three-way position, resulting in a low refrigeration efficiency of the thermoacoustic heat pump device.

[0044] It should be noted that the cooling water circulation system includes a cooling water tank, a circulation pump, and a circulation pipe. This is prior art and will not be elaborated here.

[0045] By arranging the housing 1, the three-way position of the thermoacoustic heat pump device is wrapped, and by arranging the flow guide plates 2 in the housing 1 that can divide the inner cavity of the housing 1 into a plurality of chambers 5, when the housing 1 is sleeved on the three-way position, a plurality of chambers 5 can form an S-shaped flow channel around. Furthermore, when the cooling water circulation system injects the cooling water into the housing 1 through the water inlet hole 3, the cooling water can flow along the S-shaped flow channel and be discharged from the water outlet hole 4 to take away the heat on the surface of the three-way position, thereby achieving the purpose of reducing the temperature of the three-way position of the thermoacoustic heat pump device and improving the refrigeration efficiency and operation stability of the entire thermoacoustic heat pump device.

[0046] In this embodiment, the housing 1 is further defined such that when the housing 1 is connected to the tee position of the thermoacoustic heat pump device, a sealed cavity can be formed to ensure the normal operation of the cooling water heat dissipation. Specifically, both ends of the housing 1 are provided with a frustum-shaped structure, and the outer diameter decreases from the inside to the outside to be hermetically connected to the pipe at the tee position.

[0047] Wherein, sealing rings are provided at both ends of the housing 1, that is, sealing rings are built into the frustum-shaped structure to ensure the sealing performance of the connection between the housing 1 and the tee position of the thermoacoustic heat pump device.

[0048] In addition, an opening is provided in the middle of the housing 1, so that the housing 1 forms a tee structure to complete the wrapping of the tee position of the thermoacoustic heat pump device.

[0049] In this embodiment, to facilitate the installation of the housing 1 at the tee position of the thermoacoustic heat pump device, the housing 1 is further defined here.

[0050] Specifically, the housing 1 includes two half-shells that can be fixedly connected, and the two half-shells are connected by welding to facilitate the installation of the housing 1 at the tee position to form a wrapping.

[0051] Please continue to refer to Figure 4 , and a plurality of guide half-pieces 6 are fixedly installed on the inner walls of both half-shells.

[0052] Wherein, when the two half-shells are fixedly connected, the two guide half-pieces 6 located in the same horizontal plane enclose the guide plate 2 to guide the cooling water.

[0053] In addition, a gap 7 for the cooling water to pass through is formed between the guide half-piece 6 and the top wall or the bottom wall of the inner cavity of the half-shell, and the adjacent two gaps 7 are arranged in a staggered manner, so that an S-shaped flow channel is formed around the plurality of guide plates 2, the tee position, and the housing 1 for the circulating flow of the cooling water to ensure the heat dissipation effect on the tee position.

[0054] In other embodiments, one side of the guide half-piece 6 has an arc surface matching the outer wall of the component to be cooled. Through the arc surface, the guide half-piece 6 can be clamped with the outer wall of the tee position of the thermoacoustic heat pump device for positioning, so as to further facilitate the assembly of the two half-shells.

[0055] Embodiment Two

[0056] As Figure 5 shown, on the basis of Embodiment One, this embodiment also proposes a thermoacoustic heat pump device to improve the refrigeration efficiency of the thermoacoustic heat pump device and correspondingly improve the operation stability by adding a cooling component.

[0057] Specifically, the thermoacoustic heat pump device includes a thermoacoustic heat pump body 8 and the cooling component described in the first embodiment. For the structural description of the specific cooling component, reference can be made to the introduction in the first embodiment, which will not be elaborated here.

[0058] In this embodiment, the thermoacoustic heat pump body 8 has a tee pipe 81, and the housing 1 is wrapped around and fixedly installed outside the tee pipe 81.

[0059] By adding a cooling component at the tee pipe 81 of the thermoacoustic heat pump device to dissipate heat from the tee pipe 81, the influence on the heat exchanger caused by excessive heat of the tee pipe 81 can be reduced. Correspondingly, the situation where the refrigeration rate of the heat exchanger is low due to the influence of heat can be effectively avoided. Therefore, the refrigeration efficiency of the thermoacoustic heat pump device can be effectively improved, and the operation stability can be correspondingly improved.

[0060] It should be noted that the deflector 2 is engaged with the outer wall of the tee pipe 81 to facilitate the formation of an S-shaped flow channel.

[0061] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
