Description

TECHNICAL FIELD

[0001] The utility model relates to heat exchanger technical field, concretely is a single heat source channel many cold source channel and cold source do not mix heat exchanger. BACKGROUND

[0002] In modern industrial production and many application scenarios, heat exchange is a crucial process. Whether in chemical industry, pharmaceutical, electronics, energy production or heating, ventilation and air conditioning industries, accurate temperature control has a decisive influence on product quality, production efficiency and energy utilization efficiency. For example, in the chemical synthesis process, different chemical reaction steps often need to be carried out in a specific temperature range to ensure the selectivity and yield of the reaction; in electronic equipment production, chip manufacturing and packaging process need accurate temperature control to ensure the performance and reliability of the product.

[0003] Traditional conventional heat exchanger usually has only a single cold heat source channel. When there are multiple temperature sections to be controlled in the application scenario, for example, in a large data center, the servers in different areas of the computer room have different temperature control corresponding to the heat dissipation demand of different workloads, according to the traditional method, multiple independent heat exchangers need to be set up to meet the heat dissipation demand of different temperature sections.

[0004] Multiple independent heat exchangers must be controlled by multiple temperature control groups. Each temperature control group contains temperature sensors, controllers and related regulating valves and other components. In some places where the temperature control accuracy is not particularly high, but there are multiple temperature sections that need to be heat exchanged, such as ordinary industrial plants for temperature control of different process links, the configuration of multiple temperature control groups will greatly increase the cost.

[0005] Multiple heat exchangers and temperature control groups need to occupy a large space when installed. In places where space resources are scarce, such as ship engine rooms, a large number of heat exchangers and temperature control equipment will make the engine room layout crowded, not only affecting the installation and maintenance of other equipment, but also possibly affecting the overall performance of the ship, such as limiting the loading capacity of goods or affecting the operation space of personnel.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figures 1-3 As shown, an embodiment of this utility model proposes a heat exchanger with a single heat source channel and multiple cold source channels, and the cold sources are not mixed. It includes a heat exchanger body 1, a lifting ring 2 installed on the top of the heat exchanger body 1, a first cold source channel 3 and a second cold source channel 4 provided inside the heat exchanger body 1, the first cold source channel 3 and the second cold source channel 4 are separated by a partition 5, an mounting plate 6 is fixedly installed on the side of the heat exchanger body 1, a fixing foot 7 is fixedly installed on the bottom of the heat exchanger body 1, a heat source inlet and outlet pipe 8 is connected to the side wall of the fixing foot 7, the heat source inlet and outlet pipe 8 is connected to a fixing pipe 9, and a heat exchange pipe 10 is connected to the fixing pipe 9.

[0026] The heat exchanger body 1 is a container-like structure with a specific shape and size. It is the core main part of the entire heat exchanger and houses all other components.

[0027] Function: To provide a closed space for the heat exchange process, ensuring that the heat source and cold source can effectively transfer heat within it, while protecting the internal channels and components from external environmental interference.

[0028] Four lifting rings 2 are provided and distributed on the top of the heat exchanger body 1.

[0029] Function: Facilitates the hoisting and relocation of heat exchangers. During installation, maintenance, or replacement of heat exchangers, hoisting equipment can be used to safely lift the heat exchanger using lifting rings 2, allowing it to be accurately placed in the predetermined position.

[0030] The first cold source passage 3 and the second cold source passage 4 are located inside the heat exchanger body 1 and are separated by a partition 5.

[0031] Function: To provide two independent flow paths for the cold source, ensuring that different cold sources do not mix. This allows the heat exchanger to handle two cold sources of different temperatures or properties simultaneously, meeting the needs of applications with special requirements for the cold source and improving the applicability and flexibility of the heat exchanger.

[0032] The partition 5 is located between the first cold source channel 3 and the second cold source channel 4, directly separating the two.

[0033] Effect: Prevents the mixing of cold sources in the channel, ensuring that each cold source channel can flow according to the predetermined temperature and flow, thereby improving the utilization efficiency of the cold source and the accuracy of heat exchange.

[0034] The mounting plate 6 is fixedly installed on the side of the heat exchanger body 1, and the side is provided with a mounting flange hole.

[0035] Effect: By installing the flange hole, the heat exchanger can be firmly installed on the predetermined equipment or support using bolts and other connecting parts, ensuring that the heat exchanger remains stable during operation and does not displace or damage due to vibration or other external forces.

[0036] The fixed foot 7 is fixedly installed at the bottom of the heat exchanger body 1, and is provided with a threaded hole.

[0037] Effect: Through bolt connection with the installation plane, such as the ground or equipment foundation, further enhancing the stability of the heat exchanger. At the same time, the side wall of the fixed foot 7 is connected with the heat source inlet and outlet pipe 8, providing a channel for the heat source to enter and exit.

[0038] The heat source inlet and outlet pipe 8 is connected to the side wall of the fixed foot 7 and is connected to the fixed pipe 9.

[0039] Effect: As a channel for the heat source to enter and exit the heat exchanger, it allows the heat source to smoothly flow into and out of the heat exchanger body 1 and exchange heat with the cold source inside.

[0040] The fixed pipe 9 is connected to the heat source inlet and outlet pipe 8 and is connected to the heat exchange pipe 10.

[0041] Effect: It plays a connecting and transitional role in the heat source flow path, ensuring that the heat source can be evenly distributed to the heat exchange pipe 10, ensuring uniformity and efficiency of heat exchange.

[0042] The heat exchange pipe 10 is connected by one heat source inlet and outlet pipe 8 to another heat source inlet and outlet pipe 8, and is arranged alternately and parallel inside the heat exchanger body 1.

[0043] Effect: Increases the contact area between the heat source and the cold source, improving the efficiency of heat exchange. The heat source flows in the heat exchange pipe 10, and the cold source flows in the cold source channel, transferring heat through the pipe wall to achieve an efficient heat exchange process.

[0044] The working principle of the heat exchanger is as follows: the heat source enters through the heat source inlet and outlet pipe 8 connected to the side wall of the fixed foot 7, flows into the heat exchange pipe 10 arranged alternately and in parallel inside the heat exchanger body 1 through the fixed pipe 9 connected to the heat source inlet and outlet pipe 8. In the heat exchanger body 1, there are a first cold source channel 3 and a second cold source channel 4 separated by the partition plate 5, and the cold source flows in the two independent channels respectively. When the heat source flows in the heat exchange pipe 10, heat is transferred to the surrounding cold source through the pipe wall. Due to the special arrangement of the heat exchange pipe 10, the contact area between the heat source and the cold source is increased and the internal flow field is optimized, so that the heat can be efficiently transferred. At the same time, the independent arrangement of the cold source channel ensures that the cold sources are not mixed, and the utilization efficiency of the cold source is improved. The lifting ring 2 at the top facilitates the hoisting and installation of the heat exchanger, the mounting plate 6 at the side is connected to other equipment through the mounting flange hole, and the screw hole on the fixed foot 7 at the bottom is used for further stable installation. These structures together ensure the stability and reliability of the heat exchanger during operation.

[0045] As shown in Figure 1 some embodiments, the four lifting rings 2 are arranged on the top of the heat exchanger body 1. During installation, when the heat exchanger needs to be placed in a designated position, such as being installed on a specific equipment support in an industrial plant, the four lifting rings 2 provide stable connection points for hoisting equipment. By connecting suitable ropes or chains with the lifting rings 2, the heat exchanger body 1 can be safely and smoothly lifted, ensuring that it can be accurately installed in the predetermined position, avoiding damage to the heat exchanger or danger caused by uneven force during hoisting.

[0046] As shown in Figure 1 some embodiments, the mounting plate 6 has mounting flange holes on the side. The presence of the mounting flange holes allows the mounting plate 6 to be connected to other equipment or supports through bolts and other connecting components.

[0047] As shown in Figure 1 some embodiments, the fixed foot 7 is provided with screw holes. The arrangement of the screw holes allows the fixed foot 7 to be connected to the installation plane through bolts.

[0048] As shown in Figure 3 some embodiments, the heat exchange pipe 10 is connected to another heat source inlet and outlet pipe 8 in a circular and reciprocating manner. The circular and reciprocating design of the heat exchange pipe 10 allows the heat source to flow through a longer path in the heat exchanger. The heat source enters from one heat source inlet and outlet pipe 8, flows out from another heat source inlet and outlet pipe 8 through the circular and reciprocating heat exchange pipe 10, which increases the contact time and contact area between the heat source and the cold source.

[0049] As shown in Figure 2As shown, in some embodiments, the heat exchange pipes 10 are arranged alternately and in parallel inside the heat exchanger body 1; the alternately and in parallel arranged heat exchange pipes 10 greatly increase the contact area of the heat source and the cold source. Inside the heat exchanger body 1, this arrangement enables the heat exchange pipes 10 to make full use of the space, so that when the heat source flows in the pipes, the heat source can exchange heat with the surrounding cold source on a larger area.

[0050] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
