It is further used as the improvement of technical solutions of the utility model, refrigerant inlet pipe and exit are located at the same of tank body
Side.
It is further used as the improvement of technical solutions of the utility model, refrigerant exit is located at the middle part of the bottom surface of tank body.
It is further used as the improvement of technical solutions of the utility model, refrigerant inlet pipe is horizontally arranged on tank body.
It is further used as the improvement of technical solutions of the utility model, the height of refrigerant inlet is more than two points of the height of tank body
One of.
It is further used as the improvement of technical solutions of the utility model, tank body is equipped with fixed seat for fixing.
It is further used as the improvement of technical solutions of the utility model, check valve is equipped in refrigerant inlet pipe and refrigerant outlet pipe.
The beneficial effects of the utility model：This is conducive to the liquid storage tank structure of oil return, is arranged in tank body using by refrigerant inlet
Refrigerant exit is arranged in tank body bottom surface and arc-shaped curved surface is made in the bottom surface of tank body method on top so that lubricating oil exists
The resistance smaller flowed in tank body, lubricating oil can be fully entered refrigerant outlet pipe by gravity and flowed out, not only avoided in pipeline
There are gases, while avoiding lubricating oil and accumulating in tank base so that system takes liquid more effective, contributes to system oil return.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the overall structure diagram of the liquid storage tank structure conducive to oil return in the utility model embodiment.
Specific implementation mode
Referring to Fig.1, the liquid storage tank structure of the utility model for the benefit of oil return, including tank body 1, the top of tank body 1 is equipped with cold
Matchmaker's import 2, refrigerant inlet 2 connect refrigerant inlet pipe 3, and the bottom surface of tank body 1 is equipped with refrigerant exit 4, and refrigerant exit 4 connects refrigerant outlet pipe
5, the bottom of tank body 1 is arc-shaped curved surface.
Specifically, the setting of the arc-shaped curved surface of 1 bottom of tank body, reduces the resistance that lubricating oil flows in tank body 1, and make
The bottom of tank body 1 can be converged under gravity by obtaining lubricating oil, finally be flowed out from refrigerant outlet pipe 5.And the gas in tank body 1
Body is then gathered in 1 top of tank body, will not enter pipeline.Therefore, it avoids in pipeline that there are gases, while avoiding lubricating oil and existing
Accumulate 1 bottom of tank body so that system takes liquid more effective, contributes to system oil return.
As the utility model preferred embodiment, refrigerant outlet pipe 5 is L-shaped, and refrigerant outlet pipe 5 includes being connect with tank body 1
Connecting pin and with the orthogonal exit in connecting pin.
As the utility model preferred embodiment, refrigerant inlet pipe 3 and exit are located at the same side of tank body 1, specifically
, in the installation of fluid reservoir, refrigerant inlet pipe 3 and exit are arranged in the same side of tank body 1, the sky of installation can be saved
Between, keep structure compacter.
As the utility model preferred embodiment, refrigerant exit 4 is located at the middle part of the bottom surface of tank body 1 so that lubrication
The flowing convergence of oil is more convenient.
As the utility model preferred embodiment, refrigerant inlet pipe 3 is horizontally arranged on tank body 1, prevent lubricating oil into
When entering tank body 1, it is directly impinging refrigerant outlet pipe 5.
As the utility model preferred embodiment, the height of refrigerant inlet 2 be more than the height of tank body 1 two/
One so that lubricating oil has certain gravitional force, the flowing of fluid more smooth.
As the utility model preferred embodiment, tank body 1 is equipped with fixed seat 6 for fixing.
As the utility model preferred embodiment, it is equipped with check valve in refrigerant inlet pipe 3 and refrigerant outlet pipe 5, is prevented
Fluid pours in down a chimney.
This is conducive to the liquid storage tank structure of oil return, is arranged on 1 top of tank body, by refrigerant outlet pipe 5 by being arranged refrigerant inlet pipe 3
In 1 bottom surface of tank body and the method that arc-shaped curved surface is made in 1 bottom surface of tank body so that the flowing and aggregation of fluid are more smooth, simultaneously
Gas can be converged to 1 top of tank body, gas is avoided to enter pipeline.Compact overall structure, and manufacturing cost is low, has higher
Promotional value.
Certainly, the invention is not limited to the above embodiment, and those skilled in the art are without prejudice to originally
Equivalent variations or replacement can be also made under the premise of utility model spirit, these equivalent modifications or replacement are all contained in the application
