Description

A kind of constant-temperature circulating device of use PTC heating
Technical field
The present invention relates to a kind of constant-temperature circulating device of PTC heating.
Background technology
During enterprise's production refrigeration product, as environmental requirement is constantly strengthened, increasing enterprise needs Use the characteristics of super low temperature refrigeration agent such as R170, carbon dioxide, super low temperature refrigeration agent be on its critical-temperature, no matter pressure More high, it can all be maintained at gaseous state;Given this present invention carries out heated constant temperature processing when super low temperature refrigeration agent filling machine is used.
The content of the invention
It is an object of the invention to provide a kind of constant-temperature circulating device of PTC heating, the present invention is ultralow temperature refrigerant filling Machine provides a kind of suitable temperature environment, is that filling machine carries out the stable premise accurately filled.
In order to achieve the above object, the technical scheme is that:
A kind of constant-temperature circulating device of PTC heating, including refrigerant accumulator, PTC heaters, EGR, the first temperature Detection means and second temperature detection means;PTC heaters are installed in described refrigerant accumulator outside wall surface;Described Offered at the top of refrigerant accumulator in circulation import, described refrigerant accumulator and the first temperature-detecting device, institute are installed Tee one-way valve is installed in the refrigerant accumulator bottom stated, and described tee one-way valve one end connects with refrigerant accumulator bottom Logical, the second end is used as refrigerant accumulator liquid outlet as refrigerant accumulator inlet, the 3rd end;Described inlet is with entering Liquid pipe is connected, and described liquid outlet is connected with drain pipe;Described drain pipe and the inlet communication of EGR;Described circulation The outlet of device passes through pipeline and the circulation inlet communication at the top of refrigerant accumulator, and described EGR and circulation import Between pipeline on be also equipped with second temperature detection means;Circulation import at the top of described refrigerant accumulator also passes through pipe Road is connected with liquid feeding machine gun head.
Beneficial effects of the present invention are:The present invention provides a kind of suitable temperature environment for ultralow temperature refrigerant filling machine, is Filling machine carries out the stable premise accurately filled;PTC heaters of the present invention have that thermal resistance is small, heat exchange efficiency is high, are a kind of automatic constants Temperature, the electric heater of power saving.Security can be improved, will not be produced such as the table of electric heating tubing heater under any applicable cases Face " rubescent " phenomenon, so that cause scald, the potential safety hazard such as fire.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Embodiment 1
As shown in figure 1, a kind of constant-temperature circulating device of PTC heating of the present embodiment, including refrigerant accumulator 1, PTC heating dress Put 2, EGR 11, the first temperature-detecting device 3 and second temperature detection means 9;The described outside wall surface of refrigerant accumulator 1 On PTC heaters 2 are installed;The described top of refrigerant accumulator 1 offers circulation import 8, described refrigerant energy storage First temperature-detecting device 3 is installed, tee one-way valve 7, described three are installed in the described bottom of refrigerant accumulator 1 in device 1 Logical one end of check valve 7 is connected with the bottom of refrigerant accumulator 1, and the second end is used as refrigerant accumulator inlet 4, the 3rd end conduct Refrigerant accumulator liquid outlet 5;Described inlet 4 is connected with feed tube 12, and described liquid outlet 5 is connected with drain pipe 13; The import 6 of described drain pipe 13 with EGR 11 is connected;The outlet 10 of described EGR 11 passes through pipeline and refrigeration The circulation import 8 at the top of agent accumulator 1 is connected, and is also installed on the pipeline between described EGR 11 and circulation import 8 There is second temperature detection means 9;The circulation import 8 at the described top of refrigerant accumulator 1 also passes through pipeline and liquid feeding machine gun head 14 connections.
It is that a kind of PTC heaters are called ptc heater that the present embodiment, which proposes PTC heaters, is generated heat using PTC-ceramic Element is constituted with aluminum pipe.
A kind of constant-temperature circulating device of PTC heating of the present embodiment, described the first temperature-detecting device 3 detection refrigerant The real time temperature of accumulator 1;Described second temperature detection means 9 is used for the environment temperature of detecting system.First with refrigerant The conveying refrigerant of inlet 4 on the bottom tee one-way valve 7 of accumulator 1 enters refrigerant accumulator 1;Then 2 pairs of PTC heaters Described refrigerant accumulator 1 carries out entirety and is heated to assigned temperature(40 degrees Celsius)When, the refrigerant in refrigerant accumulator 1 EGR 11 is transported to by the liquid outlet 5 on tee one-way valve 7, EGR 11 is started working, when second temperature detection Device 9 detects system temperature and reaches design temperature(38 degrees Celsius)When, i.e., the described temperature of refrigerant accumulator 1 is higher than setting During temperature, PTC heaters 2 start fine setting decline temperature to design temperature, to reach state of the system with respect to constant temperature;Work as beginning During filling, EGR 11 is stopped, and refrigerant is conveyed to liquid feeding machine gun head 14 by refrigerant accumulator 1.External refrigeration Agent enters EGR by feed tube 12, and EGR starts next circulation.
The present embodiment provides a kind of suitable temperature environment for ultralow temperature refrigerant filling machine, is that filling machine carries out stablizing accurate The premise of filling;The present embodiment PTC heaters have that thermal resistance is small, heat exchange efficiency is high, are a kind of automatic constant-temperature, the electrical heating of power saving Device.Security can be improved, surface " rubescent " phenomenon such as electric heating tubing heater will not be produced under any applicable cases, from And cause scald, the potential safety hazard such as fire.
