Abstract
The utility model discloses a cooling unit evaporator comprising an outer cylinder of a heat exchanger, a heat exchanging pipe and an end plate which is connected with the heat exchanging pipe, wherein the end plate which is provided at one end of the outer cylinder of the heat exchanger comprises an inner end plate and an outer end plate, the inner end plate is provided with two symmetrical connecting holes which are used for connecting the heat exchanging pipe. A plurality of the heat exchanging pipes is bent to the ports of the two ends towards bent pipes of the inner end plate, and the two ends ports are expansion connected with the connecting holes, the corresponding grooves of the ports of the two ends of the heat exchanging pipes are arranged on the outer end plate separately. The grooves form an isolated cavity chamber after the inner end plate locks with the outer end plate mutually, one end port of the cavity chamber of the corresponding heat exchanging pipe is connected with a coolant liquid-inlet pipe, and the other end port of the cavity chamber is connected with the coolant return-air pip. The evaporator of the utility model is good in the heat exchanging effect, simple in structure, low in production costs without any leakage.
Description
Technical field
The utility model relates to a kind of evaporimeter, mainly is to be used for the refrigerating plant evaporimeter that the Cool-water Machine for Industry field particularly relates to some acidity, corrosive substance cooling.
Background technology
Existing stainless steel evaporimeter mainly is to adopt spiral heat exchange tube, and referring to Fig. 1, its joint is welded, and not only plumb joint leaks easily, and refrigerant directly flows through from spiral heat exchange tube, and heat exchange area is little, does not have sufficient heat exchange, thereby influences refrigeration.
The utility model content
The purpose of this utility model is at the problems referred to above, provide a kind of simple in structure, cost is low, heat-transfer effect good, antileakaging refrigerating plant evaporimeter.
For achieving the above object, the technical solution adopted in the utility model is: a kind of refrigerating plant evaporimeter, comprise the heat exchanger urceolus, the end plate of heat exchanger tube and connection heat exchanger tube, described end plate is located at an end of described heat exchanger urceolus and by interior, outer end plate constitutes, on inner end plate, be arranged with the connecting hole that is used to connect described heat exchanger tube, described heat exchanger tube is complex root and bends to the bend pipe of the two ends mouth of pipe towards described inner end plate, and its two ends mouth of pipe difference expanded joint is in described connecting hole, and on outer end plate, be respectively equipped with and described heat exchanger tube two ends mouth of pipe corresponding groove, described groove outer end plate in described fastens the back and forms isolated each other chamber, the chamber of the corresponding heat exchanger tube one end mouth of pipe connects the refrigerant feed tube, and the chamber of the corresponding other end mouth of pipe connects the refrigerant muffler.
Because evaporimeter of the present utility model adopts the many bend pipes that bend to U-shaped directly to be connected on the end plate, the heat exchange area of itself and evaporimeter is bigger, the heat exchange effect is relatively good, and heat exchanger tube in the middle of do not have joint and with the end plate expanded joint together, can not produce leakage; One end of many heat exchanger tubes connects one of them chamber, and being connected to the refrigerant feed tube by this chamber, the other end is connected to another chamber and is connected in the refrigerant muffler by this chamber, realizes that refrigerant is in the shunting of each heat exchanger tube with compile, it is relatively simple for structure, and manufacturing cost is lower.
