Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, and more specifically, to a structure for heating a gas-liquid separation refrigerant by utilizing a reactor. Background Art

[0002] An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source to a high-level heat source. It can convert low-level heat energy that cannot be directly used into usable high-level heat energy, thereby achieving the purpose of saving some high-level energy. The temperature of the gas-liquid separator in the air source heat pump is generally -30° during use, so the refrigerant in the gas-liquid separator needs to be heated before use.

[0003] The prior art discloses a top-outlet integrated air source heat pump unit, including a chassis body, a sleeve-type condenser is arranged at the bottom end of the chassis body, a balance tank and an economizer are arranged on the chassis body next to the right end of the sleeve-type condenser, a gas-liquid separator is arranged in the sleeve-type condenser, a compressor is arranged next to the front end of the sleeve-type condenser, the compressor is connected to the sleeve-type condenser, the gas-liquid separator and the U-shaped condenser through a four-way valve connecting pipeline, the U-shaped condenser is arranged in the top of the chassis body, an electric control box is arranged at one end of the compressor away from the sleeve-type condenser, a fan installation port is opened at the top of the chassis body, the fan installation port is arranged above the center of the U-shaped condenser, a fan is arranged on the fan installation port, and the economizer is connected to the U-shaped condenser and the balance tank through a throttling component. The scheme arranges the gas-liquid separator in the sleeve-type condenser, and uses the low temperature of the gas-liquid separator to help the condenser improve the condensation efficiency.

[0004] However, the surface of the condenser in the prior art is usually cold during use, which will reduce the efficiency of the gas-liquid separator in heating the refrigerant; and the air source heat pump in the prior art ensures smooth operation of the current by adding an inductor, but the inductor is a heat-generating device, and the prior art does not take any heat dissipation treatment for the inductor, which easily causes the temperature inside the electric control box to rise, which will not only affect the performance of the internal components and reduce the efficiency of each component, but may even cause the performance of the entire equipment to decline and reduce the service life of the equipment. Therefore, the prior art has the technical problems of low heating efficiency of the refrigerant by the gas-liquid separator and ineffective heat dissipation of the inductor. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art that the heating efficiency of the gas-liquid separator for the refrigerant is low and the reactor does not obtain reasonable heat dissipation, and provides a structure for heating the gas-liquid separation refrigerant by using the reactor.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A structure for heating a gas-liquid separation refrigerant using a reactor comprises a gas-liquid separator and a reactor coil arranged outside the gas-liquid separator, wherein two ends of the reactor coil are respectively vertically spirally wound from the top or bottom end of the gas-liquid separator to the other end of the gas-liquid separator.

[0008] The utility model discloses a structure that utilizes an inductor to heat a gas-liquid separation refrigerant. The inductor coil generates heat when in use. The two ends of the inductor coil are respectively vertically spirally wound from the top or bottom end of the gas-liquid separator to the other end of the gas-liquid separator, so that the inductor coil heats the refrigerant for the gas-liquid separator. Not only the inductor coil is effectively cooled, but also the heating efficiency of the gas-liquid separator for the refrigerant is improved, and the temperature inside the electric control box and the performance of the internal components are not affected. The technical problems in the prior art that the heating efficiency of the gas-liquid separator for the refrigerant is low and the inductor does not effectively cool down are effectively solved.

[0009] Furthermore, the reactor coil is attached to the outer wall of the gas-liquid separator. Attaching the reactor coil to the outer wall of the gas-liquid separator not only reduces the heat conduction efficiency, improves the efficiency of heating the refrigerant, but also improves the fixing strength between the reactor coil and the gas-liquid separator.

[0010] Furthermore, a base is provided at the bottom of the gas-liquid separator, and the lower end of the reactor coil can be fixed to the base. The lower end of the reactor coil is fixed to the base to support the reactor coil.

[0011] Furthermore, the base is provided with a fixing ring coaxially arranged with the gas-liquid separator, the fixing ring is provided with a notch, the bottom end of the reactor coil is provided with a first fixing plate, and the first fixing plate can be vertically inserted into the notch. The base is provided with a fixing ring coaxially arranged with the gas-liquid separator, the fixing ring is provided with a notch, and the first fixing plate at the bottom end of the reactor coil is vertically inserted into the notch, so that the rotation of the reactor coil can be restricted.

[0012] Furthermore, the inner wall diameter of the fixing ring is larger than the outer wall diameter of the gas-liquid separator, and a flanged groove is provided between the inner wall of the fixing ring and the outer wall of the gas-liquid separator, and the reactor coil can be accommodated in the flanged groove. Since the inner wall diameter of the fixing ring is larger than the outer wall diameter of the gas-liquid separator, the distance between the inner wall of the fixing ring and the outer wall of the gas-liquid separator is set as the flanged groove, so that the reactor coil can be accommodated in the flanged groove, forming a partial wrapping of the reactor coil, and having a radial limiting effect on the reactor coil.

[0013] Furthermore, the notch penetrates from the inner wall of the fixing ring to the outer wall of the fixing ring, and the direction of the notch is parallel to the radial direction of the fixing ring. The notch penetrates from the inner wall of the fixing ring to the outer wall of the fixing ring, and the direction of the notch is parallel to the radial direction of the fixing ring, so that the first fixing plate is only limited by the rotation restriction, and the length of the first fixing plate in the radial direction of the fixing ring is not limited.

[0014] Furthermore, when the first fixing plate is placed in the notch, one end of the first fixing plate away from the gas-liquid separator passes through the outer wall of the fixing ring, and a gap is provided between the end of the first fixing plate away from the gas-liquid separator and the outer wall of the fixing ring. When the first fixing plate is placed in the notch, one end of the first fixing plate away from the gas-liquid separator passes through the outer wall of the fixing ring, and a gap is provided between the end of the first fixing plate away from the gas-liquid separator and the outer wall of the fixing ring, so that it is convenient to manually remove the connection between the reactor coil and the fixing ring by lifting the end of the first fixing plate.

[0015] Furthermore, a second fixing piece that can be vertically inserted into the notch is provided at the top of the reactor coil, and the position of the second fixing piece in the vertical direction coincides with the position of the first fixing piece. A second fixing piece that can be vertically inserted into the notch is provided at the top of the reactor coil, and the position of the second fixing piece in the vertical direction coincides with the position of the first fixing piece, so that either end of the reactor coil can be plugged and limited with the fixing ring, which is convenient for installation.

[0016] Furthermore, it also includes a heat preservation protective cover sleeved on the outer periphery of the reactor coil, the bottom of the heat preservation protective cover is placed on the upper end surface of the fixing ring, and the inner diameter of the heat preservation protective cover is larger than the inner diameter of the fixing ring. The heat preservation protective cover is sleeved on the outer periphery of the reactor coil to achieve the effect of heat preservation and protection, and the bottom of the heat preservation protective cover is placed on the upper end surface of the fixing ring to support the heat preservation protective cover; since the inner diameter of the heat preservation protective cover is larger than the inner diameter of the fixing ring, the contact between the heat preservation protective cover and the reactor coil can be avoided, thereby improving the heat preservation effect of the reactor coil.

[0017] Furthermore, a limiting boss is provided on the top of the fixing ring, and a groove is provided on the bottom of the thermal insulation protective cover, and the limiting boss can be vertically inserted into the groove. A limiting boss is provided on the top of the fixing ring, and a groove is provided on the bottom of the thermal insulation protective cover, so that the limiting boss can be vertically inserted into the groove, thereby limiting the rotation of the thermal insulation protective cover.

The two ends of the inductor coil are respectively vertically spirally wound from the top or bottom end of the gas-liquid separator to the other end of the gas-liquid separator, so that the inductor coil heats the refrigerant for the gas-liquid separator. Not only the inductor coil is effectively cooled, but also the heating efficiency of the gas-liquid separator for the refrigerant is improved, and the temperature inside the electric control box and the performance of the internal components are not affected.

[0027] Embodiment 1

[0028] like Figure 1 The figure shows a first embodiment of the utility model which utilizes a reactor to heat a gas-liquid separation refrigerant structure.

[0029] A structure for heating a gas-liquid separation refrigerant using a reactor comprises a gas-liquid separator 1 and a reactor coil 2 arranged outside the gas-liquid separator 1, wherein both ends of the reactor coil 2 are respectively vertically spirally wound from the top or bottom of the gas-liquid separator 1 to the other end of the gas-liquid separator 1. The reactor coil 2 is attached to the outer wall of the gas-liquid separator 1.

[0030] In this embodiment, if Figure 1 As shown, the reactor coil 2 will generate heat when in use. The two ends of the reactor coil 2 are respectively vertically spirally wound from the top or bottom of the gas-liquid separator 1 to the other end of the gas-liquid separator 1, so that the reactor coil 2 heats the refrigerant for the gas-liquid separator 1. Not only the reactor coil 2 is effectively dissipated, but also the heating efficiency of the gas-liquid separator 1 for the refrigerant is improved, and it will not affect the temperature inside the electric control box and the performance of the internal components, and effectively solves the technical problems in the prior art that the heating efficiency of the gas-liquid separator 1 for the refrigerant is low and the reactor is not effectively dissipated.

[0031] In this embodiment, if Figure 1 As shown, attaching the reactor coil 2 to the outer wall of the gas-liquid separator 1 not only reduces the heat conduction efficiency and improves the efficiency of heating the refrigerant, but also improves the fixing strength of the reactor coil 2 and the gas-liquid separator 1.

[0033] like Figure 1 to Figure 2 The figure shows a second embodiment of the utility model, which utilizes a reactor to heat a gas-liquid separation refrigerant structure.

[0034] This embodiment is similar to the first embodiment, except that: a base 3 is provided at the bottom of the gas-liquid separator 1, and the lower end of the reactor coil 2 can be fixed to the base 3.

The notch 41 penetrates from the inner wall of the fixing ring 4 to the outer wall of the fixing ring 4, and the direction of the notch 41 is parallel to the radial direction of the fixing ring 4. When the first fixing plate 21 is placed in the notch 41, the end of the first fixing plate 21 away from the gas-liquid separator 1 passes through the outer wall of the fixing ring 4, and there is a gap between the end and the outer wall of the fixing ring 4. A second fixing plate 22 which can be vertically inserted into the notch 41 is provided at the top of the reactor coil 2 , and the position of the second fixing plate 22 in the vertical direction coincides with the position of the first fixing plate 21 .

[0035] In this embodiment, if Figure 1 As shown, the lower end of the reactor coil 2 is fixed to the base 3 to support the reactor coil 2 .

[0036] In this embodiment, if Figure 1 As shown, a fixing ring 4 coaxial with the gas-liquid separator 1 is provided on the base 3, a notch 41 is provided on the fixing ring 4, and the first fixing plate 21 at the bottom end of the reactor coil 2 is vertically inserted into the notch 41 to limit the rotation of the reactor coil 2.

[0037] In this embodiment, if Figure 2 As shown, since the inner wall diameter of the fixing ring 4 is larger than the outer wall diameter of the gas-liquid separator 1, the distance between the inner wall of the fixing ring 4 and the outer wall of the gas-liquid separator 1 is set as the flange groove 42, so that the reactor coil 2 can be accommodated in the flange groove 42, forming a partial wrapping of the reactor coil 2, and having a radial limiting effect on the reactor coil 2.

[0038] In this embodiment, if Figure 1 As shown, the notch 41 penetrates from the inner wall of the fixing ring 4 to the outer wall of the fixing ring 4, and the direction of the notch 41 is parallel to the radial direction of the fixing ring 4, so that the first fixing plate 21 is only limited in rotation without limiting the length of the first fixing plate 21 in the radial direction of the fixing ring 4.

[0039] In this embodiment, if Figure 1As shown, when the first fixing plate 21 is placed in the notch 41, the end of the first fixing plate 21 away from the gas-liquid separator 1 passes through the outer wall of the fixing ring 4, and a gap is provided between the end of the first fixing plate 21 away from the gas-liquid separator 1 and the outer wall of the fixing ring 4, so that it is convenient to manually remove the connection between the reactor coil 2 and the fixing ring 4 by lifting the end of the first fixing plate 21.

[0040] In this embodiment, if Figure 1 As shown, a second fixing plate 22 which can be vertically inserted into the notch 41 is provided at the top of the reactor coil 2, and the position of the second fixing plate 22 in the vertical direction coincides with the position of the first fixing plate 21, so that either end of the reactor coil 2 can be plugged and limited with the fixing ring 4 for easy installation.

Among them, the top of the fixing ring 4 is provided with a limiting boss 43, and the bottom of the heat preservation protective cover 5 is provided with a groove 51, and the limiting boss 43 can be vertically inserted into the groove 51.

[0044] In this embodiment, if Figure 3 As shown, a thermal insulation protective cover 5 is put on the outer periphery of the reactor coil 2 to achieve the effect of thermal insulation and protection. The bottom of the thermal insulation protective cover 5 is placed on the upper end surface of the fixing ring 4 to support the thermal insulation protective cover 5. Since the inner diameter of the thermal insulation protective cover 5 is larger than the inner diameter of the fixing ring 4, the thermal insulation protective cover 5 can be prevented from contacting the reactor coil 2, thereby improving the thermal insulation effect of the reactor coil 2.

[0045] In this embodiment, if Figure 3 and Figure 4 As shown, a limiting boss 43 is provided on the top of the fixing ring 4 , and a groove 51 is provided on the bottom of the heat preservation protective cover 5 , so that the limiting boss 43 can be vertically inserted into the groove 51 , thereby limiting the rotation of the heat preservation protective cover 5 .
