Description

Technical Field

[0001] The utility model relates to the technical field of water source heat pumps, in particular to a water source heat pump. Background Art

[0002] A water source heat pump is a heat pump system that uses water as a heat source or heat sink for heating, cooling, and hot water production. It is an efficient and energy-saving air conditioning device that utilizes the stable temperature characteristics of the water body to absorb heat from the water body in winter for heating, and discharges indoor heat to the water body in summer to achieve a cooling effect. In the heating mode, the water source heat pump absorbs heat from the water body through the water source heat exchanger, and then uses equipment such as a compressor to increase the temperature and release the heat to the indoor space to achieve heating. In the cooling mode, the water source heat pump transfers indoor heat to the water body through the water source heat exchanger to achieve a cooling effect. The water source heat exchanger is a key component of the water source heat pump system, responsible for heat exchange with the water body, transferring heat from the water body to the heat pump system or releasing heat from the heat pump system to the water body.

[0003] For example, the Chinese patent "A water source heat pump device" with announcement number CN214634381U includes a heat pump body, a filtering mechanism is provided on the heat pump body, the filtering mechanism includes a filter box, the upper and lower end surfaces of the filter box are respectively provided with a water inlet and a water outlet, a connecting pipe is provided on the bottom end surface of the filter box, which is located at the water outlet and is used to connect the heat pump body and the filter box, a filter mounting plate is provided in the filter box, the upper end portion of the filter mounting plate is fixedly connected to the inner wall of one end of the filter box, the lower end portion of the filter mounting plate is bent upward and fixedly connected to the side wall of the filter box, and a filter is provided on the filter mounting plate.

[0004] Although the above-mentioned prior art can realize the use of water source heat pumps, in actual use, on the one hand, the electric control cabinet of the water source heat pump is difficult to dissipate heat. During the use of the water source heat pump, the heat generated by the electronic components inside the electric control cabinet will accumulate in the electric control cabinet, causing the temperature inside the electric control cabinet to rise, thereby reducing the performance of the electronic components. On the other hand, the water source heat pump is prone to vibration during operation. The vibration generated by the water source heat pump during operation will reduce the stability of the water source heat pump unit, thereby affecting the performance of the water source heat pump. Therefore, it does not meet the existing needs. In this regard, we propose a water source heat pump. Utility Model Content

[0005] The utility model aims to provide a water source heat pump to solve the problems in the above background technology that the water source heat pump electric control cabinet is difficult to dissipate heat and the water source heat pump is prone to vibration when working.

[0006] To achieve the above object, the utility model provides the following technical solutions: a water source heat pump, comprising a base, a fixing frame is arranged on both sides above the base, a rubber pad is fixedly arranged at the lower end of the fixing frame, and the rubber pad is fixedly connected to the base, a water source heat pump unit is fixedly arranged inside the fixing frame, and a mounting plate is fixedly arranged between the fixing frames on both sides; and further comprising:

[0007] An electric control cabinet is arranged at the upper end of the mounting plate, a mounting frame is fixedly arranged on one side of the electric control cabinet, a motor is fixedly arranged at the middle position of one side of the mounting frame, and four fan blades are fixedly arranged on the outside of the motor output shaft;

[0008] The air grille is arranged inside the two sides of the electric control cabinet. There are three air grilles, and the air grilles correspond to the positions of the fan blades. Three covering strips are fixedly arranged on both sides of the outside of the electric control cabinet, and the covering strips correspond to the positions of the air grilles.

[0009] Preferably, dampers are fixedly provided at the four corners of the lower end of the base, and a support spring is fixedly provided between the fixed end of the damper and the telescopic end of the damper.

[0010] Preferably, a slot is provided inside one side of the electric control cabinet, and the slot is communicated with the air grid, and an insert plate is provided inside the slot, the insert plate is slidably matched with the slot, and one end of the insert plate extends to the top of the electric control cabinet.

[0011] Preferably, a filter is fixedly provided inside the plug plate, and the filter corresponds to the position of the air grille.

[0012] Preferably, a plurality of air holes are provided at the upper and lower parts inside the mounting frame.

[0013] Preferably, an electric control element is arranged at a middle position inside the electric control cabinet, and the electric control element is fixedly connected to the electric control cabinet.

[0014] Preferably, a drain outlet is fixedly provided below one side of the water source heat pump unit, and a water inlet is fixedly provided on one side of the water source heat pump unit below the drain outlet.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can accelerate the air circulation inside the electric control cabinet through the motor and the fan blades. When the heat source water pump is working, the electric control components inside the electric control cabinet will generate heat. At this time, the motor is turned on to make the output shaft of the motor drive the fan blades to rotate. At this time, the rotating fan blades form a low pressure around them. The low-pressure area will cause the surrounding air to flow to the fan blades. At the same time, the outside air is sucked into the electric control cabinet through the air grid on one side. The air is forced to pass through the gap between the fan blades, so that the air is accelerated and pushed to the rear of the fan blades to form an airflow. At this time, the airflow with a lower temperature takes away the heat inside the electric control cabinet and is discharged from the inside of the electric control cabinet through the air grid on the other side, preventing the heat generated by the electric control components when they are working from accumulating inside the electric control cabinet, thereby improving the performance of the electric control components.

[0017] 2. The utility model can buffer the vibration generated by the water source heat pump during operation through the damper and the support spring. The vibration generated during the operation of the water source heat pump unit is transmitted to the base through the fixed frame. At the same time, during the vibration transmission process, the rubber pad absorbs part of the vibration by deformation, and the remaining vibration is transmitted to the damper and the support spring, causing the damper and the support spring to deform. The damper and the support spring absorb the generated vibration by deformation. When the vibration stops or weakens, the damper and the support spring release the stored energy to restore the base to its initial position, thereby avoiding the reduction of the stability of the water source heat pump unit due to vibration.

[0018] 3. The utility model can intercept dust in the inhaled air through the plug board and the filter. When heat dissipation is performed, the outside air enters the interior of the electric control cabinet through the air grid on one side. At this time, the dust in the air is intercepted by the filter on the plug board, so that clean air enters the interior of the electric control cabinet, and the dust-containing air enters the interior of the electric control cabinet to prevent the short circuit of the electric control component circuit. After a period of time, the plug board is pulled out of the slot and the dust attached to the filter is processed, and the processed plug board is reinserted into the slot to prevent the dust on the filter from clogging the filter mesh, thereby increasing the air intake of the electric control cabinet.

[0027] The air grille 11 is arranged inside the two sides of the electric control cabinet 10. There are three air grilles 11, and the positions of the air grilles 11 and the fan blades 19 correspond. Three covering strips 12 are fixedly arranged on both sides of the outside of the electric control cabinet 10, and the positions of the covering strips 12 and the air grilles 11 correspond.

[0028] During use, when the heat source water pump is working, the electric control element 13 inside the electric control cabinet 10 will generate heat. At this time, the motor 18 is turned on, so that the output shaft of the motor 18 drives the fan blades 19 to rotate. At this time, the rotating fan blades 19 form a low pressure around them. The low-pressure area will cause the surrounding air to flow to the fan blades 19. At the same time, the outside air is sucked into the electric control cabinet 10 through the air grid 11 on one side. The air is forced to pass through the gaps in the fan blades 19, so that the air is accelerated and pushed to the rear of the fan blades 19 to form an airflow. At this time, the airflow with a lower temperature takes away the heat inside the electric control cabinet 10 and is discharged from the inside of the electric control cabinet 10 through the air grid 11 on the other side.

[0029] See also Figure 1 and Figure 2 A damper 7 is fixedly provided at the four corners of the lower end of the base 1, and a support spring 8 is fixedly provided between the fixed end of the damper 7 and the telescopic end of the damper 7, so that the vibration generated when the water source heat pump is working can be absorbed by the damper 7 and the support spring 8.

[0035] Working principle: the vibration generated during the operation of the water source heat pump unit 3 is transmitted to the base 1 through the fixing frame 2. At the same time, during the vibration transmission process, the rubber pad 6 absorbs part of the vibration by deformation, and the remaining vibration is transmitted to the damper 7 and the support spring 8, so that the damper 7 and the support spring 8 are deformed. The damper 7 and the support spring 8 absorb the generated vibration by deformation. When the vibration stops or weakens, the damper 7 and the support spring 8 release the stored energy to restore the base 1 to its initial position. When heat dissipation is performed, the outside air enters the interior of the electric control cabinet 10 through the air grid 11 on one side. At this time, the dust in the air is intercepted by the filter 16 on the plug board 15, so that clean air enters the interior of the electric control cabinet 10, and the dust-containing air enters the interior of the electric control cabinet 10 to prevent the electric control element 13 circuit from being short-circuited after entering the interior of the electric control cabinet 10. After a period of time, the plug board 15 is pulled out of the slot 14 and the dust attached to the filter 16 is processed, and the processed plug board 15 is reinserted into the slot 14.
