Description

Technical Field

[0001] The invention relates to a fully enclosed electric-liquid integrated refrigerant and fluorine pump. Background Art

[0002] Data centers are the core of modern information technology infrastructure, containing a large number of servers and storage devices for processing, storing and transmitting large amounts of data. Servers are one of the most critical components in data centers, responsible for running applications and services. Since servers generate a lot of heat when processing high-load tasks, heat dissipation is an important issue in data center design and operation.

[0003] In new energy or data centers, it is necessary to transport easily vaporized media, such as Freon or other refrigerant media. Refrigerants are easily vaporized, and when pumping liquids, they need to be fully sealed and leak-proof; at the same time, no metal powder can fall into the medium during the process to avoid affecting the operation of the refrigeration system.

[0004] In refrigeration systems, a structure in which the motor and pump are separated is generally used to transport the refrigerant medium. However, this structure is large in size and cannot meet the installation requirements of a miniaturized refrigeration system. It has poor practicality and also poses certain safety hazards. Summary of the invention

[0005] The purpose of the present invention is to provide a technical solution for a fully enclosed electro-hydraulic integrated refrigerant and fluorine pump in response to the deficiencies in the prior art, which can not only make the structure of the entire pump compact and meet the installation requirements of a miniaturized refrigeration system and the transportation requirements of the refrigerant medium, but also achieve a fully enclosed connection between the pump and the motor, making it less likely to leak and preventing metal powder from falling in, thereby greatly improving the safety and reliability of the pump when in use.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A fully enclosed electric-liquid integrated refrigerant and fluorine pump, comprising

[0008] impeller;

[0009] a rotor, in which magnetic poles are embedded;

[0010] and coils;

[0011] Features:

[0012] The impeller and the rotor are an integrally processed structure or a detachable connection structure. The coil is energized to generate a magnetic field, and the magnetic poles are forced to rotate in the magnetic field, so that the rotor drives the impeller to rotate synchronously, thereby realizing stable transportation of the refrigerant. Through the design of the above structure, not only can the structure of the entire pump be compact, meeting the installation requirements of a miniaturized refrigeration system and the transportation requirements of the refrigerant medium, but also a fully enclosed connection between the pump and the motor can be achieved, which is not prone to leakage and prevents metal powder from falling in, greatly improving the safety and reliability of the pump when in use.

[0013] Furthermore, a support ring is provided inside the rotor to support the magnetic poles and prevent the magnetic poles from being deformed, thereby improving the stability and reliability of the rotor during rotation.

[0014] Furthermore, it also includes a fastener, which passes through the rotor and the magnetic poles and is connected to the impeller, so as to realize a detachable connection between the rotor and the impeller and meet the installation requirements of pumps of different sizes.

[0015] Furthermore, it also includes a volute, a pump casing and a back cover. The back cover is connected to the volute through the pump casing. A cover plate is provided between the volute and the pump casing for limiting the impeller and the rotor. Through the design of the volute, pump casing, back cover and cover plate, the entire pump can be fully enclosed, which is not easy to cause leakage and can also prevent metal powder from falling in, thereby greatly improving the reliability of the pump during use.

[0016] Furthermore, the coil is connected to the pump housing, the cover plate and the rear cover through a support frame, and the support frame improves the stability of the coil installation.

[0017] Furthermore, the rotor and the impeller are connected to the volute and the rear cover through a connecting shaft. Both ends of the connecting shaft are provided with shaft sleeves, and bearings are provided between the shaft sleeves and the rotor. The design of the above structure can lock the forward and backward moving distance of the rotor and the impeller without movement, which greatly improves the stability and reliability of the pump during operation, and at the same time can reduce noise and wear.

[0018] Furthermore, the bearing is a ceramic bearing or a wear-resistant bearing.

[0019] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0020] 1. The present invention can not only make the structure of the entire pump compact, meeting the installation requirements of a miniaturized refrigeration system and the transportation requirements of a refrigerant, but also realize a fully enclosed connection between the pump and the motor, making it less likely to leak and preventing metal powder from falling in, thereby greatly improving the safety and reliability of the pump when in use.

[0021] 2. A support ring is provided inside the rotor to support the magnetic poles and prevent them from deformation, thereby improving the stability and reliability of the rotor during rotation.

[0022] 3. A bearing is provided between the shaft sleeve and the rotor, which can lock the forward and backward moving distance of the rotor and the impeller and prevent them from moving, thus greatly improving the stability and reliability of the pump during operation, and at the same time reducing noise and wear.
