The novel flow dividing head comprises a flow dividing head body, a flow collecting cavity is formed in the flow dividing head body, a plurality of flow dividing holes are formed in the flow dividing head body, a flow guide base integrated with the flow dividing head body is arranged in the flow collecting cavity, a plurality of flow guide grooves are formed in the flow guide base in the circumferential direction, a closed base is formed between every two adjacent flow guide grooves, and flow guide plates are arranged on the two sides of each closed base. The end faces, facing the guide grooves, of the guide plates are provided with guide curved faces. The guide grooves communicate with the flow dividing holes correspondingly. The utility model has the advantages of improving the mass flow rate of refrigerant and improving the performance of functional energy efficiency.

Description

Technical Field

[0001] This utility model belongs to the technical field of air source heating and cooling units, and relates to a distributor head, especially a novel distributor head. Background Technology

[0002] When using the commonly used distributor head, the refrigerant cannot enter the distributor hole evenly, which results in the evaporator's evaporation capacity not being fully utilized, the refrigerant mass flow rate being reduced, and the unit's energy efficiency not being fully realized. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel diverter head that improves energy efficiency.

[0004] The objective of this utility model can be achieved through the following technical solution: A novel flow divider head includes a flow divider head body, which has a flow collecting cavity and multiple flow dividing holes. The flow collecting cavity contains a flow guide seat integrally formed with the flow divider head body. Multiple flow guide grooves are formed along the circumferential direction on the flow guide seat. A closed seat is formed between two adjacent flow guide grooves. Both sides of the closed seat have flow guide plates. A flow guide curved surface is formed on the end face of the flow guide plate facing the flow guide groove. The flow guide grooves are correspondingly connected to the flow dividing holes.

[0005] In the aforementioned novel distributor head, the distributor head body has a frustum groove.

[0006] Compared with existing technologies, this new type of distributor has the advantages of increasing refrigerant mass flow rate and improving functional efficiency. Attached Figure Description

[0007] Figure 1 This is a cross-sectional view of the new type of splitter head.

[0008] Figure 2 This is a structural diagram of the flow guide seat.

[0009] In the figure, 1 is the body of the flow divider; 2 is the flow collecting cavity; 3 is the flow dividing hole; 4 is the flow guide seat; 5 is the flow guide groove; 6 is the closing seat; 7 is the flow guide plate; 8 is the flow guide curved surface; and 9 is the frustum groove. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 , Figure 2As shown, this novel distributor head includes a distributor head body 1, a flow collecting cavity 2 inside the distributor head body 1, and multiple flow dividing holes 3 on the distributor head body 1. The flow collecting cavity 2 has a flow guide seat 4 integrally formed with the distributor head body 1. Multiple flow guide grooves 5 are formed on the flow guide seat 4 along the circumferential direction. A closed seat 6 is formed between two adjacent flow guide grooves 5. Both sides of the closed seat 6 have flow guide plates 7. The end face of the flow guide plate 7 facing the flow guide groove has a flow guide curved surface 8. The flow guide grooves 5 are correspondingly connected to the flow dividing holes 3. During operation, the refrigerant passes through the flow guide grooves 5 and is guided into the flow dividing holes 3 under the action of the flow guide curved surface 8 of the flow guide plate 7, so that the refrigerant is evenly distributed and promoted, thereby improving the unit's energy efficiency.

[0012] To elaborate further, the main body 1 of the distributor has a frustum groove 9. Before forging, the heated copper segment is formed into the product shape of the frustum groove 9 through a pressing die, and then the forging work continues to prevent damage from occurring inside the frustum groove 9.

[0013] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0014] Although this document frequently uses terms such as 1. flow divider body, 2. flow collecting cavity, 3. flow dividing hole, 4. flow guide seat, 5. flow guide groove, 6. closing seat, 7. flow guide plate, 8. flow guide curved surface, and 9. frustum groove, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
