Abstract

The utility model discloses a spraying and liquid storing type heat exchanger structure for a hot pump system, which comprises a casing, a pipe bunch, a fluid A entrance, a fluid A exit, a cryogen entrance and a cryogen exit. The utility model is characterized in that the entrance and the exit of the fluid A are connected to the pipe bunch in the casing, thus forming a fluid channel in the pipe bunch; the entrance and the exit of the cryogen are positioned on the wall of the casing, thus forming a cryogen channel outside of the pipe bunch; the bottom of the casing has an oil returning mouth; and the upper part of the pipe bunch has a cryogen allotter. Thus the utility model has the beneficial effects that the utility model can be used as an evaporator when in refrigeration and as a condenser when produce heat; a liquid storing machine is removed from the hot pump system, thus realizing a machine with multi functions, so as to enhance performance, reduce the quantity of cryogen and lower cost.

Description

Spray water storage type heat exchanger

Technical field

The utility model belongs to the refrigeration and air-conditioning technical field, is specifically related to a kind of spray water storage type heat exchanger that can be used for handpiece Water Chilling Units and heat pump.

Background technology

Mainly contain four critical pieces in the heat pump, two heat exchangers (evaporimeter and condenser), a compressor and an expansion valve.Direct expansion formula evaporimeter is widely used in the heat pump, its reason is that the advantage of direct expansion formula evaporimeter is both to have can be used as evaporimeter, can be used as condenser again, but direct expansion formula evaporimeter heat transfer property is poor, also needs a reservoir to store cold-producing medium unnecessary when heating.Thereby flooded evaporator replaced direct expansion formula evaporimeter gradually in large-scale handpiece Water Chilling Units, thereby improved heat transfer property greatly.But the shortcoming of flooded evaporator is: can not be used as condenser and full-liquid type and also need a large amount of cold-producing mediums, cost height, Heavy Weight in the heating mode purposes.

The utility model content

The purpose of this utility model provides a kind of spray water storage type heat exchanger that is used for heat pump, both can as condenser, can omit the reservoir that adds again when heating as evaporimeter when refrigeration.

For achieving the above object, the technical solution adopted in the utility model is: spray water storage type heat exchanger, comprise housing, place the tube bank in the housing, the import of fluid and outlet, the import of cold-producing medium and outlet, it is characterized in that: the tube bank in the import of fluid and outlet and the described housing connects to form the tube bank fluid passage, place the import and the outlet of the cold-producing medium on the housing, in described housing, form coolant channel outside the tube bank, be equipped with liquid refrigerant outlet and oil return opening in the bottom of described housing.Be in the chamber of described housing that the top of described tube bank also can be equipped with refrigerant distributor.

The beneficial effects of the utility model are: the utility model is in heat pump applications, not only can when freezing, be used as evaporimeter but also can when heating, be used as condenser, the cold-producing medium consumption that the utility model needs is few, self can store cold-producing medium unnecessary when heating, therefore can cancel the reservoir that adds in the heat pump, realized one-object-many-purposes, improved performance and reduce cost.The utility model also can be made evaporimeter and use in handpiece Water Chilling Units.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model structural representation;

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is that the utility model is made evaporimeter time spent fundamental diagram;

Fig. 4 is that the utility model is made condenser time spent fundamental diagram.

Among the figure: the 1-housing; The outlet of 2-gaseous refrigerant (evaporimeter) or import (condenser); The 3-fluid inlet; The 4-oil return opening; The 5-liquid refrigerant outlet; The 6-fluid issuing; The 7-refrigerant inlet; The 8-tube bank; The 9-refrigerant distributor.

The specific embodiment

Fig. 1, Fig. 2 is the utility model structural representation, diagram spray water storage type heat exchanger, comprise housing 1, place the tube bank 8 in the housing 1, fluid inlet 3 and outlet 6, the import 7 of liquid refrigerant and outlet (evaporimeter) 2 or the import (condenser) of gaseous refrigerant, it is characterized in that: the tube bank 8 in the import 3 of fluid and outlet 6 and the described housing 1 connects to form tube bank 8 fluid passage, the import 7 of cold-producing medium and the outlet 2 of gaseous refrigerant when making evaporimeter, make the import 2 of condenser time spent gaseous refrigerant and the shell wall that liquid refrigerant outlet 5 places housing 1, in described housing 1, form coolant channel outside the tube bank 8, be equipped with oil return opening 4 in the bottom of described housing 1.In the chamber of described housing 1, the top of described tube bank 8 also can be equipped with refrigerant distributor 9.During the work operation, the fluid of uniform temperature, in the tube bank 8 in fluid inlet 3 inflow heat exchanger housings 1, cold-producing medium enters in the heat exchanger shell 1 from refrigerant inlet 7, fluid and cold-producing medium are by the tube wall heat exchange of tube bank 8, fluid flows out from exporting 6 subsequently, and cold-producing medium is from exporting 2 or 5 outflow heat exchangers.

Fig. 3 is that the utility model is made evaporimeter time spent fundamental diagram (refrigeration), after the cold-producing medium that liquid state or gas-liquid two-phase mix enters heat exchanger inlets 7, be evenly distributed to above the tube bank 8 through distributor 9, liquid refrigerant is after tube bank 8 surfaces are by gasification, and upwards flowing arrives gas vent 2.The unevaporated refrigerant liquid of part flows to the bottom of housing 1, does pond attitude boiling after being heated, and upwards flows and arrive gas vent 2 in the gasification back.Parts of lubricating oil after the purification is got back to system from oil return opening 4.

Fig. 4 is that the utility model is made condenser time spent fundamental diagram (heating).After gaseous refrigerant entered heat exchanger inlets 2, gas was at tube bank 8 surface condensations.Condensed refrigerant liquid drops onto lower housing portion, flows out from liquid refrigerant outlet 5 then.Because the demand of filling quantity of refrigerant when heating is few when freezing, so unnecessary cold-producing medium can be stored at bottom in the water storage type heat exchanger shell 1 of the present invention when heating.

The utility model not only can be used as evaporimeter but also can be used as condenser when heating when freezing, spray water storage type heat exchanger has been realized one-object-many-purposes, has improved performance and has reduced cost.
