[0002] Air-cooled heat pump chillers are widely used in modern building air conditioning systems and other fields. The condensers used in air-cooled heat pump chillers are generally traditional S-shaped metal tube structures. Because air-cooled heat pump chillers have high power when operating, traditional condensers are not convenient for distributing refrigerant, which is not conducive to increasing the contact area with the inside of the condenser. At the same time, they lack a structure for active condensation of the condenser, which is not convenient for improving the working efficiency of the condenser, and is not conducive to shortening the working stroke and improving working efficiency.

[0003] The purpose of this utility model is to provide an air-cooled heat pump chiller unit to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Example 1: As Figures 1-5 ,include

[0028] The base, with its top fixedly installed;

[0029] The condenser includes a frame tube 100, a horizontal tube 130 and a vertical tube 140 connected inside the frame tube 100, a bridge tube 150 connected to the top of the vertical tube 140, and heat dissipation fins 160 fixedly installed on the outer wall of the horizontal tube 130.

[0030] The cooling fan assembly includes a cooling fan 220, which is located at the bottom of the condenser.

[0031] The specific application scenario of this embodiment is as follows: By setting the frame tube 100, horizontal tube 130, and vertical tube 140 in combination, the contact area between the refrigerant and the inner wall of the condenser is increased, thereby increasing the condensation efficiency. At the same time, the cooling fan 220 is evenly fixedly installed at the bottom of the frame tube 100 and the heat dissipation fins 160 with air holes 161 are evenly distributed on the outer wall of the horizontal tube 130, which improves the condensation efficiency and the stability of the air-cooled heat pump chiller unit. By setting the bridge tube 150, the refrigerant can enter the bridge tube 150 when there is too much refrigerant inside the condenser, which increases the working cavity of the condenser and improves the pressure resistance of the refrigerant inside the condenser. The frame, compressor, evaporator, and fan are components in the existing air-cooled heat pump chiller unit and are used for temperature regulation. The compressor, evaporator, and fan are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0032] Example 2: As Figure 1 and Figure 2The frame tube 100 is rectangular. The input end of the frame tube 100 is fixedly connected to the inlet pipe 110, and the output end of the frame tube 100 is fixedly connected to the outlet pipe 120. The horizontal tube 130 is fixedly installed and connected along the length of the frame tube 100, and the vertical tube 140 is fixedly connected along the width of the frame tube 100. The horizontal tube 130 and the vertical tube 140 intersect and connect with each other. The wall thickness of the horizontal tube 130 and the vertical tube 140 is 1 mm. The heat dissipation fins 160 are L-shaped, and the included angle between the two sides of the heat dissipation fins 160 is 120°-150°. The surface of the heat dissipation fins 160 is evenly provided with air holes 161, which are hexagonal. The heat dissipation fins 160 are made of aluminum.

[0033] The specific application scenario of this embodiment is as follows: by delivering refrigerant to the inlet pipe 110 and then to the frame pipe 100, and subsequently into the horizontal pipe 130 and the vertical pipe 140 connected to the frame pipe 100, the high-temperature refrigerant is quickly dispersed into each flow channel in the frame pipe 100, the horizontal pipe 130 and the vertical pipe 140, thereby increasing the contact area between the refrigerant and the inner wall of the frame pipe 100, the horizontal pipe 130 and the vertical pipe 140, and thus accelerating the condensing efficiency of the condenser.

[0034] Example 3: As Figure 1 and Figure 3 The bridge pipe 150 is set as an inverted U-shape, and there are several bridge pipes 150. The placement direction of the bridge pipes 150 is parallel to that of the horizontal pipe 130.

[0035] The specific application scenario of this embodiment is as follows: by uniformly fixing the bridge pipe 150 on the top of the horizontal pipe 130, the refrigerant can enter the bridge pipe 150 when there is too much refrigerant inside the condenser, thereby increasing the working cavity of the condenser.

[0036] Example 4: Figure 5 The cooling fan assembly includes a housing 200, with support brackets 210 fixedly installed on the top outer wall of the housing 200, and connecting blocks (not shown in the figure) fixedly installed at the four corners of the bottom outer wall of the frame tube 100. The support brackets 210 and the connecting blocks are detachably fixedly installed by screws, and cooling fans 220 are evenly fixedly installed on the inner wall of the housing 200.

[0037] The specific application scenario of this embodiment is as follows: by setting up a cooling fan group to increase the heat dissipation efficiency of the frame tube 100, horizontal tube 130, vertical tube 140 and heat dissipation fins 160, the working efficiency of the air-cooled heat pump chiller unit is improved. By setting up the support corner 210 to cooperate with the connecting block, it is convenient to evenly install the cooling fan 220 below the frame tube 100, horizontal tube 130 and vertical tube 140, so as to actively improve the heat dissipation effect on the condenser.

[0038] The working principle of this utility model is as follows: When used by those skilled in the art, the refrigerant is delivered to the inlet pipe 110 and then to the frame pipe 100, and subsequently enters the horizontal pipe 130 and the vertical pipe 140 connected to the frame pipe 100. This quickly disperses the high-temperature refrigerant into the various channels of the frame pipe 100, the horizontal pipe 130, and the vertical pipe 140, thereby increasing the contact area between the refrigerant and the inner walls of the frame pipe 100, the horizontal pipe 130, and the vertical pipe 140, thus accelerating the condensing efficiency of the condenser. At the same time, the cooling fan 220 is turned on to provide air cooling for the frame pipe 100, the horizontal pipe 130, the vertical pipe 140, and the cooling fan 220 installed on the outer wall of the vertical pipe 140, thereby improving the heat dissipation efficiency. By setting the heat dissipation fins 160 to an L-shape, the contact area with the airflow is increased, thereby increasing the efficiency of the heat dissipation fins 160 in conducting heat from the vertical pipe 140 to the external environment, thus improving the working efficiency of the condenser.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
